Medici, Islam, and Early Modern Diplomacy

The Grand Duchy of Tuscany emerged in the sixteenth century as a consolidated territorial state under the Medici, inheriting elements of Florence’s republican legacy while adapting to the logic of princely rule. Situated at the heart of the Italian peninsula – between Spanish Habsburg-controlled territories to the west and an Ottoman-dominated Mediterranean to the east – Tuscany occupied a geopolitical position that both enabled and constrained its role as a bridge between Christian Europe and the Islamic world. Though structurally a small power, like other Italian states, it nevertheless possessed the capacity to develop a more ambitious and wide-ranging diplomacy than is often assumed, operating within a highly fluid, multipolar, and interconnected diplomatic environment.Footnote ¹²

Despite this potential, the historiography on Medici Tuscany’s relations with Islamic polities has long remained narrowly circumscribed. Scholars have predominantly focused on the Islamic presence within Tuscany, such as diplomats and travellers like the Druze emir Fakhr al-DinFootnote ¹³ and, above all, merchants, captives, slaves, and Muslim women – thus using Islamic actors primarily as a backdrop for reconstructing the institutional, political, cultural, and military history of the grand duchy.Footnote ¹⁴ A similar dynamic is evident in studies of the Order of St. Stephen, where Islamic societies tend to appear merely as the antagonistic ‘other’ necessary for narrating Tuscan maritime warfare and crusading ideology. This inward-looking tendency has overshadowed the fact that Islamic powers were not simply ‘present in Tuscany’ but were active interlocutors with whom the grand duchy negotiated and interacted, and to whom it consciously projected itself in pursuit of its own political, diplomatic, commercial, and even dynastic objectives.Footnote ¹⁵ The present study seeks to redress this imbalance by reconsidering Islamic states as full partners in diplomatic exchange – agents with their own agendas, constraints, and expectations rather than passive components of Tuscan history.

In contrast to dominant historiographical models that privilege large empires and maritime republics, this study therefore examines how the Medici engaged in cross-confessional diplomacy with Islamic powers in the Mediterranean. The Medici had to fashion a diplomatic identity that projected sovereignty and reliability while negotiating from a position of relative weakness. Building on the Florentine state’s earlier experience of negotiations with Islamic polities in the Middle Ages, Medici cross-confessional diplomacy thus exemplifies a mode of engagement characterised by adaptability, calculated pragmatism, and the strategic use of symbolic, social, and material resources.Footnote ¹⁶ In a premodern context in which state institutions were often fragile, Medici envoys resembled the ‘diplomatic entrepreneurs’ described by Erik Thomson: individuals who mobilised personal resources, practical expertise, and extensive cross-cultural networks to advance state interests.Footnote ¹⁷

This flexible infrastructure enabled Medici Tuscany to pursue diplomatic strategies that balanced Christian affiliation with interfaith engagement, revealing a constant tension between ideological posture and practical necessity. As part of the Res publica Christiana, Tuscany was embedded in a framework that demanded ideological cohesion against Islam and a public commitment to crusade.Footnote ¹⁸ Yet, in practice, commercial imperatives, political survival, and the pursuit of strategic autonomy encouraged more nuanced forms of interaction. Tuscan and non-Tuscan agents acting on behalf of the Medici frequently operated under strict confidentiality; official correspondence was carefully crafted to obscure direct dealings with Islamic authorities; and embassies to Islamic courts were often couched in deliberately ambiguous terms. Such practices were not anomalous but reflected broader patterns of early modern diplomacy, which functioned less through rigid institutional structures than through overlapping jurisdictions, hybrid identities, and multi-layered networks of authority.Footnote ¹⁹

In this sense, Medici Islamic Mediterranean diplomacy exemplifies what Stephen Krasner defines as ‘organized hypocrisy’, namely a stable public rhetoric of non-intervention that could be formally upheld even as rulers discreetly violated it when interests required. This disjunction between normative discourse and diplomatic practice was not incidental but structural, allowing the Medici to address multiple audiences simultaneously.Footnote ²⁰ Although formally constrained by its close relations with the Holy See and its integration within the Spanish–Habsburg system, the Medici exploited such ambiguities to assert a degree of autonomy. The grand dukes used their titles and papal connections to reinforce legitimacy while cultivating relations with Muslim rulers to extend regional influence. The latter, in turn, pursued similarly pragmatic forms of diplomacy with Christian powers, often cutting across confessional divides. Early modern Tuscan–Islamic relations thus reveal not only the strategies of a small state in a complex geopolitical arena but also the limits within which such strategies operated, both materially and conceptually.Footnote ²¹ In this respect, it appears appropriate to include Safavid Persia in the analysis. Although not a Mediterranean state in the strict sense, lacking direct access to the sea, it exerted a significant albeit indirect influence on Mediterranean affairs through its military, diplomatic, and commercial activities.Footnote ²² Moreover, Medici–Safavid negotiations during the period under consideration were largely oriented towards the Mediterranean, encompassing proposals for joint military action in the Levant and Tuscan participation in trade routes linking Persia to Mediterranean markets.Footnote ²³ This orientation further underscores how Safavid Persia entered Medici horizons primarily through Mediterranean strategic concerns, even as it remained external to the region’s institutional frameworks.

Aims and Structure

This Element reassesses the diplomatic history of the early modern Mediterranean by examining the Grand Duchy of Tuscany’s sustained engagement with Islamic polities between 1574 and 1610, showing how a small but ambitious state sought to operate across confessional boundaries while remaining structurally constrained. Three analytical strands – self-fashioning, patronage, and negotiation – structure both the approach and the organisation of the study, in dialogue with actor-oriented and praxeological perspectives developed by Hillard Thiessen and Christian Windler.Footnote ²⁴

First, self-fashioning forms a crucial dimension of Medici diplomatic activity. The grand duchy consistently sought to craft and project an image of sovereign authority that exceeded its material power, adopting ceremonial codes, rhetorical strategies, and forms of representation designed to affirm parity with much larger states. Through these practices, diplomacy became a stage upon which the Medici articulated their political identity and aspirations within a competitive international arena.

A second axis is patronage. Medici diplomacy relied heavily on a dispersed network of envoys, brokers, merchants, and informants who operated across the Mediterranean’s multiple cultural and political frontiers. The mobilisation of such figures – often personally tied to the ruling house – underscored the extent to which early modern diplomacy depended on personalised authority, patronage networks, and flexible loyalties. Through these agents, the Medici maintained channels of communication and negotiation that formal institutions alone could not sustain.

Finally, the study emphasises the role of negotiation – not simply in the transactional sense, but as a sustained process through which meanings, categories, and hierarchies are continually redefined. Cross-confessional diplomacy required Tuscan agents to navigate complex interpretive frameworks, balancing ideological expectations with pragmatic needs and translating between distinct political cultures. These negotiations reveal diplomacy as a dynamic and relational practice, shaped as much by symbolic communication as by material interests.

These three strands are explored through three interconnected case studies, each capturing a distinct yet complementary dimension of Medici engagement with Islamic powers and illustrating how diplomatic practice operated across courts, ports, and informal networks. The first section examines Tuscany’s late sixteenth-century efforts to re-establish formal diplomatic and commercial relations with the Ottoman Empire, focusing on Bongianni Gianfigliazzi’s mission to Constantinople under Grand Duke Francesco I. By comparing Gianfigliazzi’s account with other diplomatic narratives of his mission, this section shows how political autonomy was performed rather than possessed and how it remained embedded within the hierarchies of the Catholic world, even in the Ottoman capital.

The second section shifts westward to explore Medici negotiations with North African powers, particularly the Ottoman government in Algiers and the Saadian sultanate of Morocco. Drawing on the correspondence between the Corsican merchant Andrea Gaspari and Grand Duke Francesco I, it reconstructs a dense web of commercial diplomacy, intelligence gathering, and informal patronage, emphasising how Gaspari sought to secure Medici favour through the exercise of diplomatic functions in the Maghreb.

The final section examines a ‘diplomatic incident’ involving the Safavid Empire, namely the 1610 negotiations for the release of Safavid captives in Livorno. The arrival of Shah Abbas I’s agent, Khoja Safar, forced Grand Duke Cosimo II to balance relations with a Muslim ally against the ideological constraints of engaging with a non-Christian sovereign. The episode underscores the role of intermediaries, the ambiguity of legal and religious status, and the interaction between high diplomacy and everyday port practices, while also revealing the structural limits of Medici diplomacy – particularly its reliance on Tuscan categories to interpret unfamiliar political realities.

Taken together, these three cases will show that Medici diplomacy operated not through a fully coherent or sovereign system, but through adaptive, situational practices shaped by asymmetries of power, institutional constraints, and the need to reconcile ideological commitments with strategic interests. Rather than acting merely as a client of larger powers, the Medici tried to craft a diplomatic identity grounded in autonomy, reliability, and pragmatism – yet one that remained contingent, negotiated, and often constrained in both scope and effectiveness.

1.1 Introduction

Upon learning that Duke Cosimo I (r. 1537–1574) had dispatched his galleys to help the Knights of St. John (also known as Knights of Malta) in the defence of the Maltese islands in 1565, the Ottoman government responded with a decision of significant political, diplomatic, and commercial consequence for Medici policy in the Levant. Albertaccio degli Alberti, the Florentine bailo (the official delegate tasked with supervising both diplomatic and commercial affairs) in Constantinople, was ordered by Grand Vizier Sokollu Mehmed Pasha to leave the city, along with all the Florentines residing there, as the Medici, by assisting the sultan’s enemies, had violated the ahidnâme (capitulations) that obliged them to remain allies of the Ottoman Empire.Footnote ²⁵ Florence, which for over a century had maintained political and commercial relations with the Sublime Porte – and benefited from agreements and privileges granted to its community in the Ottoman Empire since the late 1450s – found itself barred from trade in the Ottoman Levant.Footnote ²⁶

This abrupt rupture dealt a serious blow to Tuscan trade in the Eastern Mediterranean, which had long depended on the export of Florentine woollen cloth and manufactured goods in exchange for raw silk and spices carried along Asian trade routes. Following an earlier decline in the first half of the sixteenth century, largely caused by the Ottoman–Safavid conflict of 1532–1555, Tuscan commerce in the Levant continued to wane for two interconnected reasons. Politically, Medici alignment with the Habsburgs and Cosimo I’s establishment of the crusading Order of St. Stephen in 1562 cast the Duchy of Florence more as a Mediterranean adversary than as a friendly polity in Ottoman eyes. Economically, the Tuscan cloth industry increasingly turned toward Western markets – particularly Spain – reflecting the strong ties the Medici had cultivated with the Spanish Monarchy since their restoration to power in the 1530s.Footnote ²⁷

A fully fledged diplomatic policy aimed at re-establishing political and commercial ties between the Duchy of Tuscany (elevated to a grand duchy in 1569) and the Ottoman Empire only emerged in the early 1570s. As both Florentine and Ottoman sources attest,Footnote ²⁸ Grand Duke Francesco I de’ Medici (r. 1574–1587) launched a concerted effort to revive relations with the Sublime Porte, which had further deteriorated after the Battle of Lepanto owing to the anti-Ottoman activities of the Order of St. Stephen.Footnote ²⁹ Francesco’s motivations were twofold. On the one hand, he sought to elevate the grand duchy’s status as an autonomous Mediterranean power, and the Porte offered a prominent stage on which to project the duchy’s newly consolidated rank, with the papal creation of the grand ducal title and its imperial ratification (1576) forming the political prelude. Accreditation at the Ottoman court would translate that legal status into Mediterranean recognition. On the other hand, facing growing pressure from the Florentine Wool Guild (Arte della Lana), which emphasised the need to restore commercial ties amid ongoing crises in Western markets, Francesco pursued a new capitulation that could revive Levantine demand for Tuscan woollens and secure protections for his merchants in key Ottoman ports and cities.

Francesco thus made the renewal of Medici–Ottoman relations a central aim of his foreign policy, capitalising on a favourable geopolitical and diplomatic context – marked by the decline of Venetian trade in the Levant during and after the War of Cyprus (1570–1573), and by the increasing Ottoman engagement with Western powers at the outset of Murad III’s reign (r. 1574–1595). His objectives were likewise twofold: first, to secure a new set of capitulations from the sultan while diplomatically dissociating the grand duchy from the naval operations of the Knights of St. Stephen against Ottoman ships, ports, and subjects – stressing that the Order’s galleys acted under papal and Spanish authority; and second, to attract Levantine merchants to Livorno by offering assurances of free circulation and favourable commercial conditions.Footnote ³⁰

However, after a series of preliminary and discreet diplomatic initiatives, it was only in the spring of 1577 that Grand Vizier Sokollu Mehmed Pasha advised Francesco I to send a fully accredited ambassador to formalise new capitulations.Footnote ³¹ Francesco’s initiative reflected a broader Medici strategy aimed at reshaping Tuscany’s image not only within the Ottoman Empire but across the Mediterranean. By securing new capitulations, the Medici sought to place themselves on an equal footing with their principal competitors in the Levant – namely, the French and the Venetians. The ensuing diplomatic mission, entrusted to the Knight of Malta and Florentine patrician Bongianni Gianfigliazzi (c. 1549–1616), proved unsuccessful. Despite a highly favourable reception in Constantinople, Gianfigliazzi, adhering strictly to instructions from Florence, refused to comply with Murad III’s demand that the new treaty include a clause guaranteeing that the galleys of the Order of St. Stephen would refrain from attacking Ottoman vessels.Footnote ³²

Perhaps precisely because of its unexpected outcome, Gianfigliazzi’s embassy has attracted considerable scholarly attention, with each study emphasising different aspects. Historiography has examined the mission’s origins, development, and conclusion, shedding light on the intended diplomatic treaty, the controversies surrounding the galleys of St. Stephen, the ambassador’s navigation of courtly alliances and rivalries at the Porte, and, finally, the rich cultural exchanges between Florence and Constantinople prompted by Gianfigliazzi’s journey to the Ottoman capital in 1578.Footnote ³³

Building on this substantial body of historiographical research, the following section seeks to reinterpret Gianfigliazzi’s diplomatic mission, with particular emphasis on a previously neglected dimension: diplomatic representation. Recent scholarship has highlighted the centrality of representation in shaping early modern cross-cultural encounters, especially within the Ottoman context, where ceremonial practices, visual self-fashioning, and interconfessional dynamics were crucial in defining political legitimacy and facilitating intercultural communication.Footnote ³⁴ By interweaving Tuscan sources with Venetian, French, and Spanish materials, the section examines how Gianfigliazzi presented himself at the Ottoman court and, by extension, how he embodied the authority of the Medici grand dukes. It also considers how his approach was perceived by other agents with whom he interacted daily in Constantinople.

1.2 Why Bongianni Gianfigliazzi?

Bongianni Gianfigliazzi, born in Florence, hailed from one of the city’s oldest and most respected patrician families, noted for its loyalty to the Medici. The earliest record of him dates to April 1568, when, at the age of eighteen, he entered the Order of St. John as a novice – a decision likely motivated by a family strategy to consolidate its prestige at the court of Cosimo I.Footnote ³⁵ From that moment onwards, investiture as a knight required, alongside the vows of poverty, chastity, and obedience, a one-year period of military apprenticeship designed to complement the religious training received by the novice in Malta.Footnote ³⁶ It was during this apprenticeship that Gianfigliazzi first demonstrated his valour. According to Giacomo Bosio, in the summer of 1570 some twenty Algerian galleys under Uluç Ali Pasha attacked vessels of the Order on which Gianfigliazzi was serving. During the fighting, one of these ships was abandoned by its commander and left exposed to the Algerine corsairs. Gianfigliazzi, risking his life, did not flee; instead, he distinguished himself by assisting the sub-scrivener Michele Calli in preventing the enemy from capturing the vessel’s standard.Footnote ³⁷ Although Bosio records that only Calli was formally honoured in Malta by the grand master, it is very likely that Gianfigliazzi was also present and received recognition for his bravery in the encounter.Footnote ³⁸

After completing his novitiate and receiving the investiture, Gianfigliazzi took part in the Battle of Lepanto (7 October 1571), during which he was wounded and captured by the Ottomans before the tide turned in favour of the Holy League. He was brought to Constantinople and disappears from the record until his ransom, which, according to Vanna Arrighi, occurred approximately six years later.Footnote ³⁹ As a member of the Florentine patriciate and of the Maltese Order, it is likely that Gianfigliazzi was not subjected to hard labour in the Ottoman capital. It is reasonable to assume that, as a highly valued war prisoner, he fell into the hands of an Ottoman grandee or one of the few admirals who had survived Lepanto, who saw in him an opportunity either to demand a substantial ransom or to secure an exchange for Muslim captives.Footnote ⁴⁰

Bongianni Gianfigliazzi’s years as a war prisoner in Constantinople may have allowed him to acquire knowledge of Ottoman politics and the customs of the capital’s elite, and to establish personal connections with various courtly figures. This experience provided him with insights that likely influenced Francesco I’s decision to entrust him with representing the grand duke in Constantinople.Footnote ⁴¹ Indeed, in one of his earliest letters, dated 20 November 1577, Gianfigliazzi wrote to the Tuscan Secretary of State about his mission, making clear both his prior familiarity with Ottoman court etiquette and the importance he attached to diplomatic representation as a means of safeguarding Francesco’s reputation:

The advice Gianfigliazzi offered in this letter – regarding the necessity of wearing a long Ottoman caftan, as required by protocol for ambassadors to the Sublime Porte, rather than a short Florentine robe – cannot, however, be taken as primary evidence that this knowledge was the reason Francesco entrusted him with the mission. Indeed, the language used by the knight makes clear that he had already received orders to depart for Constantinople.

To understand this decision, it is useful not only to consider the knowledge Bongianni Gianfigliazzi likely acquired during his captivity but also to examine Francesco I’s decision to appoint a fully accredited ambassador to the Porte in 1577. Compared with earlier diplomatic agents sent from Florence to the Ottoman court, Gianfigliazzi’s appointment represented an unprecedented development in Medici–Ottoman relations. Previous attempts to renew relations with the sultan and secure commercial privileges for Tuscan subjects had been entrusted to two merchants and a soldier, who conducted negotiations discreetly and without ambassadorial credentials. In 1574, for example, Ludovico Canacci, a merchant of the Wool Guild, was sent to Constantinople not as the grand duke’s envoy but as the mandatario of the guild consuls. According to his instructions, Canacci, using a safe-conduct issued by Sokollu Mehmed Pasha to Florence, was to travel covertly from Ancona to Ragusa and thence to the Ottoman capital.Footnote ⁴³

However, Canacci failed, due to the contemporaneous attacks by the galleys of St. Stephen on Ottoman vessels, and a second attempt was made in 1575 by Camillo Terranova, a Florentine merchant resident in Constantinople. Acting on his own initiative, Terranova persuaded the Porte’s dragoman and Lucchese renegade, Hürrem Bey, to explore once more the possibility of reopening negotiations with the grand vizier, although he did not pursue them further.Footnote ⁴⁴

The last attempt, and perhaps the most illuminating for understanding Gianfigliazzi’s mission, was that of the soldier Pietro Ammannati, who was dispatched in early 1577 to the Bosphorus in secret, carrying a new letter from Francesco I to Sokollu Mehmed, in which the former reiterated the desire to renew ‘the friendship, commerce, and good understanding that has already existed between the Majesty of the Grand Seigneur and our Florentine Republic’ and the ‘most flourishing state of Tuscany’.Footnote ⁴⁵ Details of this attempt are preserved in the dispatches of the Venetian bailo in Constantinople Giovanni Correr. In a report to the doge, on 17 June 1577, Correr provides a vivid account of this unusual mission. He noted that Ammannati was known to many merchants in Constantinople, having previously been there as a captive ‘together with a Knight of Malta, Buonfigliazzi, his master, and was freed together with him.’ However, the bailo emphasised that Ammannati was ‘no man of business, [since] he cannot read or write, but rather a small soldier.’ According to Correr, Ammannati departed from Ancona for Ragusa but, receiving no assistance from the Ragusans, who did not recognise him, resolved to present himself to the local sanjakbey. Claiming to be French and carrying letters of great importance for the grand vizier, he secured an escort who accompanied him until he delivered the letters to the dragoman Hürrem Bey. The latter immediately presented Ammannati to Sokollu Mehmed, in whose presence the Florentine former captive submitted Francesco I’s letter. After a brief dialogue concerning his journey, Ammannati was dismissed and instructed to reside in Hürrem Bey’s house until the grand duke’s message was examined and a decision made.Footnote ⁴⁶

The grand vizier’s reply arrived promptly. Translated by Hürrem Bey and dispatched to Florence in mid-July 1577, Sokollu Mehmed’s letter combined courtesy with caution. Addressed to ‘the glorious lord among the great Christian princes, the Grand Duke of Florence, Don Francesco’, it acknowledged receipt of the grand duke’s letters and his desire to renew the ancient friendship once enjoyed with the Porte, along with confirmation of certain capitulations. However, while expressing willingness to uphold this relationship, the grand vizier made clear that the confirmation of capitulations could only be granted once a fully accredited ambassador had presented himself at court, ‘according to the [Ottoman] custom’.Footnote ⁴⁷ The letter thus placed the onus on Francesco I to send a formally accredited envoy, elevating the negotiations from the level of discreet intermediaries such as Canacci, Terranova, and Ammannati to recognised diplomatic engagement. This signalled the sultan’s willingness to reopen political communication with Tuscany and imposed a condition that effectively tested the seriousness of the grand duke’s intentions after years of low-profile diplomatic attempts.

At this turning point in relations between Florence and the Ottoman court, the choice of a fully accredited ambassador to Constantinople fell upon Gianfigliazzi for several reasons, not solely because of his prior knowledge of Ottoman etiquette. Regarding the commercial aspects of the negotiations, it was clear that Gianfigliazzi possessed relevant expertise. Indeed, according to the Florentine merchant and traveller Filippo Sassetti, the ideas underlying his treatise ‘On Trade between Tuscany and the Levantine Nations’ in support of Tuscan-Ottoman commerce were in fact Gianfigliazzi’s own, as Sassetti revealed in a letter of September 1577.Footnote ⁴⁸

In addition, after receiving his commission, Gianfigliazzi reported that, on his own initiative, he had assembled six of the most experienced Florentine merchants to review the text of the new set of capitulations. In this exercise, he revealed his diplomatic approach, aimed at enhancing the image and reputation of the grand duke, through two key recommendations. Firstly, he proposed that the term ‘Tuscans’ in the capitulations be replaced with ‘subjects of the Most Serene Grand Duke’, in order, as he explained, to prevent other merchants from benefiting from future commercial privileges in the Ottoman Empire. Secondly, he urged a decision regarding the status of the envoy sent to reside in Constantinople (whether ambassador or bailo), ensuring that the choice would secure some ‘advantage over the other’ diplomatic actors.Footnote ⁴⁹ This consideration was far from merely nominal: whereas the ambassador functioned as a diplomatic envoy vested with the full authority of a sovereign and charged with the execution of a specific mission, the bailo combined the ambassador’s representative and negotiatory functions with responsibilities pertaining to the protection of a nation’s mercantile community – duties typically associated with a consul. Nevertheless, within the intricate hierarchy of diplomatic precedence at the Ottoman court, the ambassador customarily ranked above the bailo. Consequently, the choice between the two, which Gianfigliazzi entrusted to the discretion of the grand duke, appears to have been shaped both by the specific objectives of the diplomatic undertaking and by the desire to secure enhanced representational advantages at the Porte.Footnote ⁵⁰

Setting aside these details – which attest to Bongianni Gianfigliazzi’s unquestionable loyalty to the grand duke and his direct involvement with the Florentine commercial sector pressing for the reopening of negotiations with the Ottomans – a possible explanation for his selection as diplomatic agent emerges from a letter sent in early 1578 by the head of the Spanish espionage network in Constantinople, the Venetian Aurelio Santa Croce, to Hürrem Bey. Santa Croce confirmed that he had received Francesco I’s most recent correspondence, in which it was indicated that he had followed both his own advice and that of Hürrem Bey regarding the appointment of Gianfigliazzi as his ambassador to negotiate the Medici-Ottoman capitulations.Footnote ⁵¹

Beyond his principal role as coordinator of King Philip II of Spain’s (r. 1556–1598) spies in Constantinople, Santa Croce was also a merchant active in both the lucrative business of slave redemption and the trade in Italian textiles. He regularly provided various Italian powers, including Venice, Genoa, and Florence, with valuable reports on the daily Ottoman affairs, using his brother Giovanni Antonio as intermediary.Footnote ⁵² These factors, together with the correspondence between Santa Croce and the grand duke revealed in the letter to Hürrem Bey, indicate that the Venetian spymaster, with the assistance of the dragoman, orchestrated the reopening of negotiations between Florence and the Porte, seeking personal and financial advantage in light of the substantial debts he had accumulated.Footnote ⁵³

Beyond the fact that Gianfigliazzi’s appointment resulted not from a private grand ducal decision but from counsel provided by a merchant and a renegade in Constantinople, two further, interrelated considerations appear reasonable. First, Gianfigliazzi likely became acquainted with both Santa Croce and Hürrem Bey during his captivity in Constantinople and maintained relations with them after his ransom. Indeed, according to another letter from Santa Croce to Hürrem Bey in 1578, he was instructed to deliver ‘a sum of money on behalf of the Grand Duke’, who was eager to see the Venetian spymaster in Florence soon.Footnote ⁵⁴ Second, this suggests that Santa Croce may also have orchestrated Ammannati’s earlier mission, particularly given that he similarly facilitated diplomatic dialogue between the Spanish Monarchy and the Ottoman court around the same period. In spring 1577, for instance, he had introduced another former Christian captive, the Spaniard Martín Vázquez de Acuña, to Hürrem Bey and Grand Vizier Sokollu Mehmed, laying the groundwork for Spanish–Ottoman negotiations.Footnote ⁵⁵ This pattern underscores Santa Croce’s behind-the-scenes influence and suggests that his attempts at rapprochement were carefully calibrated to serve personal ambition: to enhance his status as a cross-cultural mediator in both Ottoman and Western courts by aligning his initiatives with the Mediterranean policies of the Medici and the Spanish Habsburgs.

1.3 Self-Fashioning and Representing the Grand Duke in Constantinople

Analysing the composition of Bongianni Gianfigliazzi’s embassy, the selection of gifts for the sultan, and the route chosen to reach Constantinople highlights the importance the grand duke attached to diplomatic representation and to crafting a strong image of himself and his state, both for Ottoman interlocutors and for other Western representatives on the Golden Horn. As Ulrike Ilg has noted, the embassy was conceived as a vehicle through which the grand duke sought to impress the Ottoman government, the local elite, and the wider community of Western ambassadors, merchants, and travellers gathered on the Bosphorus, thereby displaying the power, wealth, and authority of the Grand Duchy of Tuscany in the Levant.Footnote ⁵⁶ Although, unlike in the case of Ludovico Canacci, the formal diplomatic instructions given to Gianfigliazzi in the summer–autumn of 1577 have not survived, the extensive correspondence he maintained with Francesco I de’ Medici allows the reconstruction of the entire journey from Florence to Constantinople.Footnote ⁵⁷

Accompanying Gianfigliazzi and his immediate household, including his servant Pietro Ammannati, were other knights of the Order of St. John, notably the Florentine Francesco Taddei and the Milanese Francesco Spina. To this initial group were added the textile merchant Iacopo Mormorai – designated to serve as resident bailo should negotiations succeed – the court musician Giulio Caccini, and the painter Iacopo Ligozzi, recently entered into Medici service, together with ten Ottoman slaves newly freed by Francesco I. In line with diplomatic standards of the period, the heterogeneous composition of the embassy and the prestige of certain members reflected Francesco I’s intention to present himself in Constantinople as the ruler of a state whose subjects included knights, patricians, men devoted to the arts, and even freed Muslim slaves.Footnote ⁵⁸

Diplomatic representation, however, derived its force not solely from the standing of the embassy’s members. As recent studies arising from the material turn in diplomatic history have shown, gifts were powerful instruments capable of conveying performative messages regarding the donor’s wealth, authority, and grandeur, as well as the posture and intent of the giver towards the recipient.Footnote ⁵⁹ Alongside this symbolic function, diplomatic gifts also served a practical purpose: they publicised luxury goods and rarities obtainable only through exchange with specific geopolitical regions.Footnote ⁶⁰ As Özden Mercan has demonstrated in her detailed analysis of the gifts presented by Gianfigliazzi’s embassy to members of Murad III’s court, the objects chosen by the Medici were intended not merely to display the grand duke’s generosity and splendour, but above all to draw the attention of the Ottoman elite to luxury goods they might continue to enjoy once stable diplomatic and commercial relations were re-established – thereby directly challenging the Venetian monopoly over precious wares and textiles in the Ottoman market.Footnote ⁶¹

The inventory of gifts brought by Gianfigliazzi in the spring of 1578 included, beyond a large quantity of silk and wool garments embroidered with gold, a range of luxury items tailored to the political and diplomatic rank of the Ottoman court’s members. These comprised a coach for the sultan, ‘crossbows, small sets of scissors, golden flowers, feather flowers, silk flowers, candied fruits and other confections’,Footnote ⁶² crystal jugs; special oils reputed to counteract poisons; tables inlaid with pietre dure; and two Portuguese world maps, perhaps intended to signal the Medici as a unique commercial partner capable of bridging the eastern Mediterranean with the Atlantic world.Footnote ⁶³

The enormous expenditure borne by the Medici treasury to acquire and dispatch these gifts underscores the high importance attached to securing an agreement with the sultan. Nonetheless, these costs appear to have indirectly reduced the funds available to the ambassador for his journey. Although on 28 February 1578 Francesco I instructed his treasurer to allocate no less than 6,000 scudi to cover Gianfigliazzi’s mission expenses,Footnote ⁶⁴ only a few days later the ambassador wrote to the grand duke requesting ‘some further assistance’ to meet the mounting costs, which had even compelled him to leave certain members of his embassy behind in Florence, including the musician Caccini and the painter Ligozzi.Footnote ⁶⁵

While some of the most prestigious gifts travelled by sea for logistical reasons, departing from the port of Livorno on a Lucchese galley, as in the case of the coach destined for the sultan, Gianfigliazzi and his embassy followed the Adriatic-Balkan route to reach the Ottoman capital.Footnote ⁶⁶ The logistics of this expedition further underscore the importance attached to diplomatic representation. Transporting an ivory-adorned coach while the ambassador followed the well-established route used by other Western envoys demonstrates that the grand duke intended to make his engagement highly visible, ensuring from the outset that his embassy would be regarded on par with those of other contemporary major powers. Indeed, news of the Tuscan embassy’s departure and journey towards Ottoman territories spread rapidly across the Mediterranean.

As early as 27 November 1577, Spanish informants in Constantinople reported to the Viceroy of Naples that Sokollu Mehmed Pasha had dispatched a çavuş to Ragusa to receive ‘the ambassador of the Grand Duke of Tuscany, who is expected to arrive to confirm the capitulation of peace with this Great Turk’.Footnote ⁶⁷ By 26 February 1578, the secretary of the French embassy, Sébastien de Juyé, informed King Henry III (r. 1574–1589) that reports were circulating of the imminent arrival of the Florentine ambassador and bailo within the Ottoman Empire, noting that they had loaded their possessions onto a Lucchese galleon sailing under the French flag, which had already departed from Livorno.Footnote ⁶⁸ In a subsequent dispatch of 15 April, Juyé confirmed that ‘on the third of this month there arrived in this port the Lucchese galleon under the [French] royal flag, transporting the Duke of Florence’s gift to be presented by his ambassador and bailo to the Grand Seigneur.’ According to his informants, the gift consisted of ‘a carriage adorned and worked in ivory, flowers of silk and gold thread made by the nuns there, and confitures or pastes from Genoa.’ Beyond the details of the present itself, Juyé’s report also revealed the identity of the ambassador, whom he identified as ‘a certain Knight Giovan Filiassi [sic].’Footnote ⁶⁹ Similar news was relayed almost simultaneously by other diplomatic observers: the Venetian bailo Barbarigo reported it to Venice,Footnote ⁷⁰ while Giovanni Margliani, the Milanese agent sent to Constantinople by Philip II, transmitted parallel intelligence to Madrid.Footnote ⁷¹ These observations demonstrate not only the vigilance of French, Venetian, and Spanish intelligence in monitoring Medici diplomacy in the Levant, but also the extent to which the Tuscan embassy had already attracted attention before reaching Ottoman territory. The entire diplomatic community in Constantinople was aware that Tuscany’s direct negotiation with the sultan had the potential to alter both Levantine commercial dynamics and the broader political balance of the Mediterranean. Far from keeping Gianfigliazzi’s mission secret, as had been the case with Canacci and Ammannati, Francesco I deliberately sought to signal that the Grand Duke of Tuscany had dispatched an accredited ambassador, accompanied by lavish gifts, to Constantinople.

After spending three weeks at the port of Ancona, from late March to mid-April, due to the unavailability of a suitable vessel for crossing the Adriatic, the Tuscan embassy finally reached Ragusa in early May. From there, Gianfigliazzi reported to the grand duke not only the excellent reception he had received from the local authorities but also that the Sanjak of Herzegovina had already dispatched a safe-conduct, along with several janissaries and a çavuş, to escort him for the remainder of his journey, in accordance with the sultan’s orders.Footnote ⁷² Accordingly, upon departing from the territory subject to the Republic of Ragusa and entering Ottoman lands, Gianfigliazzi’s account of the journey consistently emphasised the exceptional treatment and hospitality afforded to him by Ottoman local authorities at each stage.Footnote ⁷³ For example, in a letter from Cernizza (present-day Cernica, Romania), he reported that the sanjakbey Sinan Bey Boljanić, brother-in-law of Grand Vizier Sokollu Mehmed, had sent one hundred horses belonging to leading figures of his court to escort him to the residence prepared for his stay. Gianfigliazzi highlighted the ‘most gracious welcome’ he received, noting that ‘the kindness and affection that were shown to me, many friends told me, had never before been extended to anyone’. Such was Sinan Bey’s generosity that, upon the embassy’s departure, Gianfigliazzi accepted not only the customary accompaniment of janissaries and a çavuş but also the company of the governor’s nephews and relatives, as previously advised in letters from Sokollu Mehmed Pasha.Footnote ⁷⁴

The favourable impression that the Ottoman government anticipated regarding Gianfigliazzi’s arrival in Constantinople was not solely based on his own interpretation of earlier experiences. Upon reaching Adrianople in early June, he reported that, near Philippopolis, he had encountered Ragusan envoys returning from the Ottoman capital, who informed him that he was awaited at the Porte with ‘desire’. Similar sentiments were conveyed by the ambassador of the Holy Roman Empire, David Ungnad von Sonnegg, with whom Gianfigliazzi dined in Adrianople and from whom he received useful advice on negotiating.Footnote ⁷⁵

Encouraged by his fruitful encounter with Ungnad and by the favourable reports circulating regarding his arrival at the Ottoman court, Gianfigliazzi reached the district of Ponte Piccolo, approximately ten miles from Constantinople, on 18 June 1578. Ponte Piccolo (Küçükçekmece), renowned for the bridge completed by the Ottoman architect Mimar Sinan in 1560, served in the sixteenth century as the customary stopping point for Christian ambassadors preparing their formal entry into the Ottoman capital. The halt was effectively obligatory: it allowed news of the ambassador’s imminent arrival to spread through Constantinople and Galata, alerted merchants of his nation, and enabled allied diplomatic agents to be invited to witness the procession.

The ceremonial entry into the city functioned as a barometer for Western observers in the Golden Horn, indicating the quality of a sovereign’s diplomatic representation. It was simultaneously a performative act that signalled respect for the sultan while reaffirming the prestige of his court.Footnote ⁷⁶ In this respect, the embassy of Francesco I was no exception. Gianfigliazzi recalled that on Sunday, 22 June, he entered Constantinople with due pomp, welcomed not only by Ottoman courtiers and high officials but also by the Holy Roman ambassador Joachim von Sinzendorf, the Venetian bailo Barbarigo, and the influential Jewish broker Joseph Nasi, along with envoys from Ragusa and Lucca and representatives of the Latin-rite Christian community of Galata. Sinzendorf even remarked that, had he not been bound by strict orders to remain at his residence, he would have come in person to greet him.Footnote ⁷⁷

Gianfigliazzi’s testimony suggests that he sought to convey to Francesco I, the highly visible and ceremonially staged nature of his arrival, recognised both by Ottoman officials and by the broader community of Western representatives in Constantinople. Up to that point, the spectacle of his entry fulfilled its representational function, affirming the Grand Duchy of Tuscany’s status as a legitimate Mediterranean power worthy of ceremonial recognition alongside the major European polities. However, other diplomatic agents in Constantinople offered markedly different assessments, indicating a far less unanimous or enthusiastic reception than Gianfigliazzi portrayed. Sébastien de Juyé, for instance, noted that the Florentine ambassador had not received the honours accorded to the Venetian bailo, with whom Gianfigliazzi aspired to be considered equal, particularly since no official provision had been made for him by the sultan, as was customary for ‘ambassadors of great princes.’Footnote ⁷⁸ Similarly, Spanish informants observed that, despite the lavish gifts Gianfigliazzi had brought, the reception fell short of expectations, failing to match that accorded to the Venetian ambassador.Footnote ⁷⁹

The most revealing assessment, however, came from the Venetian bailo Barbarigo, who, in a dispatch to the doge on 18 June, described the tense negotiations surrounding the ceremonial reception of the Grand Duchy of Tuscany’s ambassador. Barbarigo reported that Hürrem Bey’s attempts to secure an honourable welcome for Gianfigliazzi – including the presence of the Çavuşbaşı (head of imperial couriers, responsible for protocol and palace ceremonies) and the Silahtar Ağa (imperial sword keeper) – were firmly rejected by Grand Vizier Sokollu Mehmed Pasha. According to the Venetian bailo, Sokollu Mehmed explicitly maintained that such honours were reserved ‘only for ambassadors of kings’, dismissing any comparison between the treatment accorded to the Grand Duke of Tuscany and that granted to the Republic of Venice. Even when Hürrem Bey argued for at least a distinction between ‘ambassador and bailo’, implicitly invoking Gianfigliazzi’s superior diplomatic rank – which, in principle, warranted a correspondingly higher level of treatment – his request was nonetheless refused.Footnote ⁸⁰ Consequently, Barbarigo noted, only twenty-two çavuşes and a handful of low-ranking officials were dispatched to receive Gianfigliazzi – far below the standard expected for a full ambassadorial reception. Moreover, his efforts to secure the customary banquet and financial provisions generally granted to newly arrived ambassadors were unsuccessful, leaving Francesco I’s representative ‘deeply dissatisfied’.Footnote ⁸¹

From these accounts, it becomes clear that Gianfigliazzi, through the intermediation of Hürrem Bey, sought to elevate the status of the Grand Duchy of Tuscany – at least to the level of the Republic of Venice – by orchestrating a diplomatic entry into Constantinople on par with those of Venetian baili and ambassadors, in the presence of the sultan’s highest dignitaries. This initial diplomatic failure – omitted from Gianfigliazzi’s correspondence to the grand duke for obvious reputational reasons – reveals the Ottoman perception of Tuscany as a polity clearly inferior not only to the major European monarchies but also to Venice. Indeed, in response to Hürrem Bey’s requests, Sokollu Mehmed undertook enquiries into the history and political standing of the grand duchy within Latin-Christian Europe, ultimately equating its importance with that of the Duchy of Savoy.Footnote ⁸²

Dissatisfied with his reception in the Ottoman capital and obliged to await the commencement of protocol visits with the grand vizier before his audience with the sultan, Gianfigliazzi took up residence in a house prepared for him in Galata by Ammannati.Footnote ⁸³ From the perspective of self-fashioning and diplomatic representation, this choice was deliberate: it maintained continuity with the site where the Florentine bailo and his household had resided from the late fifteenth century until their expulsion in 1566, while simultaneously distinguishing the Tuscan embassy from the Venetian and French missions, which by this time had abandoned Galata in favour of the Vineyards of Pera.

From this initial phase of accommodation and symbolic positioning, Gianfigliazzi’s mission then advanced to its formal diplomatic stage. Having established his household on the opposite shore of the Bosphorus, he was granted, in early July, permission by Sokollu Mehmed Pasha to proceed to the Topkapı Palace, where he formally presented his embassy before the Divan-ı Hümâyûn (Imperial Council). In accordance with court protocol, this session included the presentation of his credentials, the exposition of the embassy’s objectives, the possible reading of the capitulations, and, finally, the hand-kissing of the sultan and the presentation of gifts.

Gianfigliazzi’s detailed account of his first appearance before the Divan underscores both the solemnity of the ceremony and the delicate negotiations that shaped his mission. Collected at dawn from his residence in Galata by Hürrem Bey, he was escorted across the Bosphorus, where an ağa and thirty to forty çavuş, accompanied by several mounted officials, received him and led him to the gates of Topkapı. Upon entering the council chamber, the viziers rose courteously and invited him to sit opposite them. After a general exchange of remarks, Gianfigliazzi presented the capitulations, which Sokollu Mehmed read aloud. When the clause concerning the galleys of St. Stephen was reached, Sokollu objected that the grand duke ought to restrain them from corsair activity. Gianfigliazzi responded firmly that the Order’s command was entirely separate from that of the grand duchy and enjoyed privileges confirmed by the pope, the emperor, and other Christian princes; at most, he added, the grand duke could guarantee that no vessel carrying Tuscan patents would be molested, whether Muslim, Jewish, or Christian, provided it traded lawfully in Tuscan ports. Sokollu did not pursue the matter further, promising instead, together with the other viziers, to act in service of the grand duke.

Following this exchange, Gianfigliazzi was led to another chamber until summoned for the imperial audience. Introduced by the viziers and the Beylerbey of Rumelia, he was conducted by two kapıcı (doorkeepers) before Sultan Murad III. After bowing, kissing the hem of the sultan’s robe, and stepping back, he stood in silence while his entourage performed the hand-kiss in turn. Only then did he deliver his credentials and request confirmation of the capitulations, with Hürrem Bey interpreting for Sokollu, who relayed them to the sultan. Murad responded briefly but graciously before observing from a window as Gianfigliazzi’s gifts were paraded in procession. The ambassador was subsequently dismissed with honours, escorted back to the shore, and granted an allowance for his household’s sustenance by direct order of the sultan.Footnote ⁸⁴

To this account of Gianfigliazzi’s reception before the Divan, we must add the perspectives of other diplomatic actors in Constantinople, whose reports diverged markedly from that of the Medici ambassador. For instance, the Venetian bailo stressed that the treatment accorded to Francesco I’s delegation fell short of that granted to ambassadors of other European princes and sovereigns,Footnote ⁸⁵ while the French ambassador’s secretary observed that, despite the magnificence of Gianfigliazzi’s gifts, the honours he received were minimal, resembling instead the protocol typically afforded to tributary envoys from Transylvania, Wallachia, and Moldavia.Footnote ⁸⁶ Indeed, as Acıpınar has noted, Gianfigliazzi was subjected throughout his stay to ceremonial protocol reserved for mid-ranking ambassadors and voivodes.Footnote ⁸⁷

Casting the situation in the most favourable light and focusing solely on the ‘most gracious words’ he had received from the sultan, Gianfigliazzi returned that same evening to Galata, confident that he had done everything possible to represent the grandeur of the grand duke and convinced that the success of his mission was imminent. However, as several studies have shown, within scarcely five months the negotiations collapsed under the weight of converging obstacles. First, there was the discreet but determined opposition of the French and Venetian representatives, unwilling to countenance Tuscan participation in Levantine trade. Second, Gianfigliazzi committed a serious misstep by engaging directly with Şemsi Ahmed Pasha – trusted confidant of the sultan and chief rival of Sokollu Mehmed – thereby provoking the grand vizier’s wrath. Finally, and perhaps most decisively, the mission was undermined by the opposition of the Ottoman Grand Admiral Uluç Ali Pasha. For him, the prospect of recognising a power that supplied Spain’s fleets and financed the Order of St. Stephen in corsair attacks against Ottoman shipping was intolerable. The convergence of these political rivalries and personal enmities thus turned what had begun as a promising opening into a swift diplomatic defeat.Footnote ⁸⁸

Gianfigliazzi was fully aware of these dynamics, as revealed in a lengthy report dated 26 December, shortly after his arrival in Ragusa on the return journey to Florence. In his account, the mission appears less as a sequence of errors than as a disciplined attempt to navigate competing Ottoman and Christian interests while remaining faithful to Medici instructions. He recalls an auspicious opening, followed by the gradual hardening of conditions around the single sticking point: the galleys of St. Stephen. At this stage, Uluç Ali Pasha mobilised hostile intelligence and Christian intermediaries, including the French ambassador, to portray the Tuscan request as ‘unjust’, while court officials translated that pressure into juridical objections. Gianfigliazzi pursued every legitimate avenue available under early modern diplomatic practice – sequenced petitions (arz), recourse to patrons such as Şemsi Ahmed Paşa and the sultan’s mother Nurbanu,Footnote ⁸⁹ carefully calibrated gift-giving, and the insistence that Medici authority did not extend to commanding a sovereign religious-military order – yet each opening was ultimately neutralised by countermoves.Footnote ⁹⁰

Although Gianfigliazzi questioned whether he had committed any errors – leaving judgement to the grand duke – he nonetheless insisted that his efforts to represent Francesco I with dignity were beyond reproach. Yet other diplomatic actors in Constantinople perceived matters differently. In a dispatch to the doge dated 17 November 1578, the bailo Barbarigo reported that Gianfigliazzi had departed ‘most ill-satisfied’, and that both he and his accompanying gentlemen intended, upon their return to Florence, to urge the grand duke to arm galleys against Ottoman territories. Barbarigo added that they could not refrain from speaking ‘very freely, even with the Turks themselves’, about the wrongs they believed they had suffered. Ultimately, they were dismissed ‘without any show of honour or courtesy.’Footnote ⁹¹

Nevertheless, the diplomatic fiasco of 1578 did not so much end Gianfigliazzi’s career as bring the Medici venture at the Porte to a halt. He was neither disgraced nor punished by the grand duke; on the contrary, he appears to have been defended and retained as a capable servant of the state, with the failure attributed to the greed of Ottoman ministers rather than to personal shortcomings. After his return to Tuscany, and before his appointment as fully accredited ambassador to Madrid in 1583, he continued to act on Francesco I’s behalf by activating his personal ties with Şemsi Ahmed Pasha and, after his death in 1580, with his brother Hacı Pasha, in an effort to secure capitulations aligned with Medici interests. Medici–Ottoman diplomacy, however, shifted toward quieter and more discreet channels. Iacopo Mormorai, who remained in Constantinople as a private merchant after Gianfigliazzi’s departure, advised Francesco I to abandon rigid demands – especially concerning the galleys of St. Stephen – and instead pursue a revised strategy based on cultivating influential patrons at court, including offering a substantial payment to secure the grand vizier’s support for commercial privileges.Footnote ⁹²

These manoeuvres unfolded amid intense competition, as Venice – often in concert with France – sought to block any arrangement threatening its long-standing dominance of the Ottoman market. Although such opposition delayed immediate success, it did not extinguish Medici ambitions in the Levant, which resurfaced in the renewed diplomatic initiatives of Grand Duke Ferdinando I (r. 1587–1609) in the 1590s.Footnote ⁹³

1.4 Conclusions

This section has recast Gianfigliazzi’s embassy not as a straightforward tale of negotiation foiled by mischance, but as a case study in diplomatic representation – its ambitions, instruments, and limits. By foregrounding ceremonial self-fashioning, it has shown how the Medici court sought to recover political standing and commercial privileges at the Sublime Porte in the 1570s. After a decade of rupture and a series of low-profile probes – Canacci (1574), Terranova (1575), and Ammannati (1577) – Francesco I, at Sokollu Mehmed Pasha’s explicit prompting, shifted from discreet intermediaries to a fully accredited ambassador. This move signalled both the grand duke’s seriousness and his ambition to reset Tuscany’s Mediterranean profile through formal capitulations and the establishment of a resident bailo on the Golden Horn.

In this context, Gianfigliazzi’s nomination emerged at the intersection of this policy shift and a brokerage network in Constantinople: the Venetian spymaster Aurelio Santa Croce and the imperial dragoman Hürrem Bey not only helped reopen the diplomatic channel but directly advised the grand duke to appoint the Florentine patrician and Maltese knight. Crucially, his selection reflected not merely presumed familiarity with Ottoman protocol acquired during captivity but also commercial competence and consultation with Florentine merchants in shaping both the wording and posture of the prospective capitulations – down to redefining the beneficiary community as ‘subjects of the Most Serene Grand Duke’ and weighing whether an ambassador or a bailo would better serve Medici interests at the Porte.

In short, both the decision to send an accredited envoy and the choice of Gianfigliazzi arose from a programmatic Medici effort to regain status and secure commercial access by transforming exploratory missions into formally recognised diplomacy. Yet this aspiration to sovereign parity remained structurally constrained: the Grand Duchy did not act as an autonomous diplomatic power on an equal footing with established European states but remained embedded within the Spanish–Habsburg system. This significantly limited its room for manoeuvre, making it difficult – if not impossible – to renounce its alignment with the Order of St. Stephen in Mediterranean defence, a dependence that in turn obstructed sustained Ottoman capitulations or durable recognition from the Sublime Porte. Medici diplomacy was thus forced into indirect and compensatory strategies aimed at negotiating status in practice rather than securing it in principle.

On that foundation, the embassy’s representational design – its entourage, curated gifts, and staged itinerary – sought to project the Grand Duchy as a sovereign actor commensurate with established Western powers. The investment in conspicuous commodities, the staging of the entry, and the public choreography from Livorno to Constantinople were intended to advertise princely wealth and artisanal excellence while normalising Tuscany’s presence alongside Venice and France at the Ottoman court. Yet the reception exposed the limits of this strategy. Ottoman protocol carefully indexed rank and withheld the honours reserved for higher diplomatic agents, thereby reasserting a hierarchy that the Medici could not overcome and positioning the Tuscan envoy within a mid-tier ceremonial order closer to Transylvania than to Venice or France.

If representation furnished the stage, competing material interests supplied the plot. The clause concerning the Order of St. Stephen proved non-negotiable, as it touched directly on Ottoman maritime security, and the influence of Grand Admiral Uluç Ali Paşa was decisive in blocking any settlement that failed to restrict Tuscan corsairing proxies. French and Venetian actors, in turn, mobilised intelligence networks and political leverage to obstruct Medici advances in Levantine trade. Gianfigliazzi’s diplomatic repertoire – sequenced petitions, recourse to patrons, calibrated gift-giving, and strict adherence to Florentine instructions – could secure audiences and courtesies, but not the core objective: capitulations free of a binding anti–St. Stephen clause.

The embassy thus illuminates a broader pattern in early modern Medici–Ottoman relations. Representation could open doors, shape perceptions, and momentarily elevate a middling power; it could not, on its own, dislodge entrenched commercial monopolies, override naval strategy, or neutralise the competitive logic of a crowded diplomatic system. The Medici experiment in visibility did succeed in rendering the grand duchy newly legible on the Golden Horn. Yet it faltered where ceremonial display met the structural constraints of Ottoman protocol and Mediterranean realpolitik. In this sense, the mission’s failure is analytically productive: it reveals where ceremony yields to structure and how status, commerce, and security together define the limits of diplomatic representation.

Hence, by treating Gianfigliazzi’s mission as a laboratory of diplomatic representation – rooted in a sequence of prior probes and in a deliberate Medici decision to accredit – this section has clarified how the Grand Duchy of Tuscany sought to manufacture international standing and where that effort encountered its limits in late sixteenth-century Constantinople.

2.1 Introduction

These words – written from Valencia on 1 September 1577 by the Corsican merchant-cum-diplomat Andrea Gaspari to Grand Duke Francesco I – reveal far more than a routine offer of diplomatic service. Gaspari not only proposed to facilitate contact with the Saadian Sultan Abd al-Malik, then consolidating his power in Morocco; he also claimed, with striking confidence, that he could induce the ruler himself to seek an alliance with the Grand Duchy of Tuscany. In doing so, he placed himself at the centre of a potential diplomatic realignment, presenting his agency in the Maghreb as both indispensable and uniquely effective. The reference to ‘magnificent horses’ and to his readiness to report on ‘all the particulars of those kingdoms’ further underscores this self-fashioning: he portrayed himself simultaneously as procurer of coveted goods, gatherer of intelligence, and mediator capable of navigating North African political landscapes. Taken together, Gaspari’s words articulate a strategy in which practical service, privileged knowledge, and political initiative converge.

It is from this revealing passage that the present section unfolds, bringing into focus a largely overlooked dimension of late sixteenth-century Medici Mediterranean diplomacy – its entanglements with the Maghrebi world.Footnote ⁹⁵ Gaspari’s unpublished correspondence with the grand duke thus offers a rare vantage point on Tuscan ambitions in the western Maghreb at a moment when the Mediterranean was witnessing early attempts to negotiate a ceasefire between the Spanish Monarchy and the Ottoman Empire.Footnote ⁹⁶ Within this shifting geopolitical landscape, the Medici began to reconceptualise their ports – above all Livorno – not merely as commercial hubs but as strategic interfaces between Christian Europe and the Islamic world.Footnote ⁹⁷

Far from being a marginal figure, Andrea Gaspari exemplifies a broader category of liminal intermediaries operating at the intersections of multiple polities and cultures. His trajectory unsettles conventional narratives of diplomacy as a purely state-driven enterprise, revealing instead how informal agents could shape foreign relations through personal initiative, strategic self-fashioning, and overlapping loyalties that were as transactional as they were opportunistic.Footnote ⁹⁸ In this light, Medici commercial and diplomatic activity in North Africa during the seventeenth century appears not as a sudden innovation but as the culmination of earlier experimental gestures initiated by figures such as Gaspari in the 1570s.Footnote ⁹⁹ By tracing how one individual sought to convert intercultural expertise into political capital at the Medici court, this section contributes to a broader understanding of diplomacy ‘from below’ and shows how small Mediterranean powers, such as Medici Tuscany, could project influence across the Maghreb through informal and personalised channels.Footnote ¹⁰⁰

2.2 The Gaspari Family in the Western Mediterranean

The story of the Gaspari family unfolds across the turbulent waters of the western Mediterranean. Originating from the small village of Morsiglia in northern Corsica, its history was marked by the chronic political and social instability that characterised the region. By the mid-sixteenth century, the island – formally a possession of the Republic of Genoa and administered since 1453 by the Bank of St. George (Casa di San Giorgio) – was repeatedly caught between French and Genoese ambitions, as well as cycles of famine and civil strife.Footnote ¹⁰¹ From this environment, Andrea, together with his brothers Francesco, Filippo, and Mariano, emerged not merely as survivors but as actors capable of navigating one of early modern Europe’s most complex geopolitical arenas.

Exiled amid the collapse of Sampiero da Bastelica’s revolt against Genoese rule, the brothers dispersed across Mediterranean ports in search of opportunity. Francesco settled in Valencia, where his commercial ventures soon drew Spanish suspicion over alleged dealings with North African corsairs. Andrea, by contrast, established himself in Ottoman Algiers, cultivating ties with local officials and Maghrebi elites. These two poles – Valencia and Algiers – became the anchors of a wider family network that combined trade, intelligence, and informal diplomacy.Footnote ¹⁰²

Their transformation from marginal merchants into politically useful intermediaries was facilitated by a deliberate strategy of humanitarian framing. By presenting commercial voyages to the Maghreb as missions for the redemption of Christian captives, they secured royal licences from the Spanish Monarchy and shielded themselves from accusations of smuggling.Footnote ¹⁰³ The cause of ransom and redemption thus functioned both as moral justification and as a practical cover for expanding their Mediterranean reach.Footnote ¹⁰⁴ Andrea’s liberation of five knights of St. Stephen in 1566 under Cosimo I, and later the rescue of the nephew of Pope Pius V (r. 1566–1572), further enhanced his reputation and access to elite circles.Footnote ¹⁰⁵

As the brothers consolidated their position in Spain, Italy, and the Maghreb, their activities extended beyond commerce and the redemption of captives. Though never professional diplomats in the strict sense, they functioned as intermediaries within an emerging system of indirect diplomacy: an informal and pragmatic network of political communication that developed in sixteenth-century Habsburg Spain to circumvent the formal Christian ban on accredited relations with Muslim rulers. This system relied on a heterogeneous array of actors – merchants, friars, soldiers, slaves, renegades, and local authorities – who, under the guise of non-political pursuits such as trade or captive redemption, maintained vital channels of negotiation, intelligence, and representation in the Maghreb. The Gaspari brothers’ involvement in this milieu thus exemplifies a discreet diplomatic practice in which political functions were exercised without institutionalisation or formal status, enabling the Spanish Monarchy to engage in dialogue and contingent agreements while preserving its confessional and ideological posture before Christendom.Footnote ¹⁰⁶

Particularly around the time of the Battle of Lepanto (1571), when the Spanish Monarchy sought new strategies to destabilise Ottoman control in the Maghreb, the Gaspari were enlisted in clandestine negotiations. Most notably, Andrea and Francesco were selected by Philip II and the Viceroy of Valencia to liaise secretly with Uluç Ali Pasha, then Ottoman governor of Algiers, in a bold attempt to orchestrate his defection to the Habsburg side. Although the plan ultimately failed, it demonstrated the extent to which the Gaspari brothers’ connections within the Ottoman sphere in Algiers were trusted – and exploited – by the Spanish Crown to gather political intelligence on their rivals.Footnote ¹⁰⁷

Thereafter, the brothers’ enterprise rapidly evolved into a family-run system combining diplomatic intelligence and trade. Francesco remained in Valencia, overseeing the legal and logistical operations of their vessels, while Andrea, based in Algiers, negotiated directly with local authorities. Together, they played multiple roles – merchants, informers, discreet diplomatic envoys, and smugglers – embodying the fluid and hybrid identities characteristic of borderland actors in the early modern Mediterranean.Footnote ¹⁰⁸ At the same time, they navigated a rising tide of suspicion. Spanish officials and viceroys, Christian clerics, and rival merchants repeatedly accused them of colluding with Ottomans in Algiers, manipulating ransom rates, and trading contraband under royal licence. Although these allegations never fully materialised into formal charges, they fostered a climate of mistrust that complicated the Gaspari brothers’ activities and threatened their reputation in Spain.Footnote ¹⁰⁹

To sustain their operations, therefore, the Gaspari cultivated a strategic network of patrons. Francesco maintained a clientelist relationship with Antonio Pérez, King Philip II’s Secretary of the State’s Council (Consejo de Estado), fulfilling personal requests and dispatching rare goods from North Africa. For example, in a letter to Pérez in 1569, he detailed the shipment of a fine silk alchisseo [sic], a pair of small Damascene knives, and a piece of Turkish cloth intended for doublets, alongside other items for the king and his confessor, Fray Bernardo de Fresneda. As the letter’s closing indicates, the beneficiaries of this luxury trade were not limited to Pérez: both Philip II and Fray Bernardo regularly received exotic objects from the Maghreb. Indeed, between the late 1560s and early 1570s, the Gaspari brothers repeatedly sent a wide array of items from Algiers, including vases and jugs from Constantinople, boxes of pistachios from Lebanon, North African textiles, and exotic birds.Footnote ¹¹⁰

By the early 1570s, it had become evident to the Gaspari that their prospects extended beyond Algiers, reaching further west into Morocco. Their longstanding relationship with Abd al-Malik, a Saadian prince then in exile in Algiers, presented a unique opportunity.Footnote ¹¹¹ Andrea had assisted him in managing debts, promoted him as a Christian ally to Spanish officials, and maintained personal correspondence advocating for his eventual claim to the Moroccan throne. When Abd al-Malik successfully reclaimed the Saadian sultanate in late 1576, Andrea’s loyalty was richly rewarded: he was incorporated into the inner circle of the Moroccan court, granted trading monopolies on key exports such as sugar and cochineal, and entrusted with managing the Saadian state’s foreign affairs, including its diplomatic relations with Spain and Portugal.Footnote ¹¹²

This new position marked a decisive expansion of Andrea’s Mediterranean network. He now exercised influence not only in Spanish diplomatic circles but also in shaping Morocco’s foreign policy in the region. In 1578, following the Battle of Alcácer Quibir – which profoundly altered Moroccan politics – Andrea was appointed as a diplomatic agent of the Saadian court.Footnote ¹¹³ The new sultan, Ahmad al-Mansur, entrusted him with a dual mission: to return the body of the Portuguese king Sebastian I, who had died at Alcácer Quibir, to Iberian territory as a gesture of diplomatic respect, and to secure the release of Portuguese and Spanish prisoners of war. In this capacity, Andrea simultaneously acted as a Moroccan envoy while maintaining his loyalty to Philip II.Footnote ¹¹⁴

These missions brought Andrea not only substantial material rewards – royal grants and commercial licences from both the Spanish and Portuguese crowns for him and his brother Francesco – but also trans-imperial prestige. Particularly, he emerged as a figure of remarkable diplomatic adaptability, trusted by Saadian sultans, Ottoman governors, and Iberian monarchs alike. Yet among all the alliances he had cultivated throughout the 1570s, it was his relationship with the Medici that most clearly reflected his deeper ambitions and strategic objectives. Indeed, as commercial opportunities in the Iberian sphere began to wane for the Gaspari family, Andrea increasingly turned his attention towards Tuscany. Ports such as Pisa and, after the 1580s, Livorno had become thriving hubs of Mediterranean trade with the Levant, offering promising prospects for expanding the family’s mercantile profits. This pivot occurred at a time when Andrea and Francesco, despite their prior diplomatic services between Valencia and Algiers, were gradually falling out of favour at Philip II’s court. Persistent suspicions regarding their loyalty had eroded the trust required to assign them new diplomatic negotiations. Compounding the situation, their commercial ventures in the Maghreb were deteriorating, as reported by the merchant Luigi Vacone in Algiers. Confronted with these challenges, Francesco and Andrea even considered abandoning their Maghrebi enterprises entirely and relocating to more prosperous Mediterranean ports, following the example of their brothers Filippo and Mariano, who had moved to Marseille. From that moment, while Francesco sought royal licences to resettle in Seville – perhaps facilitated by his connections to the powerful Corsican merchant Juan Antonio Vicentelo – Andrea began focusing on Tuscan ports as a potential solution to the family’s declining economic fortunes.Footnote ¹¹⁵

However, Andrea’s turn towards Florence was motivated not only by economic foresight but also by political pragmatism. In a letter to Francesco I, dated March 1574, he expressed his intention to settle in Tuscany, emphasising his desire to serve the Medici personally and to facilitate trade with the Levant, including the most lucrative Ottoman markets of Constantinople and Alexandria. To underscore his serious commercial ambitions, Andrea noted that he had a capital of five thousand ducats ready to invest in this new venture, as he was actively seeking a more favourable commercial environment than Valencia – one that the Tuscan harbours appeared particularly well suited to provide.Footnote ¹¹⁶

Drawing on his longstanding presence in North Africa and his growing familiarity with both Ottoman governors and Saadian princes, Andrea sought to present himself as uniquely positioned to facilitate a Medici entry into the Maghrebi world, in exchange for securing licences to relocate with his associates to Tuscany. As this section turns to Andrea’s attempt to persuade the grand duke to support his personal ambitions, it highlights the most visionary phase of his career – a period in which the Corsican devoted himself to winning Medici favour. Through letters sent from the Maghreb and the Iberian Peninsula, gifts dispatched to Florence, and projected futures shaped by Medici diplomatic engagement in Morocco, we can discern the outlines of an emerging Tuscan diplomacy in North Africa, moulded by the aspirations of Andrea Gaspari as he navigated the thresholds of the western Mediterranean.

2.3 Andrea Gaspari, the Maghreb, and the Medici

The correspondence between Andrea Gaspari and Francesco I – here reconstructed for the first time through a small yet revealing set of letters preserved in the ‘Carteggio Universale’ collection of the Mediceo del Principato fund of the State Archives of Florence – provides insight into how the Corsican sought to leverage his position in North Africa for personal gain. Far from being passive, Andrea strategically positioned himself as an indispensable intermediary by offering his services in intelligence gathering, cross-cultural negotiation, and commercial facilitation to the Medici. His letters, sent from Algiers, Valencia, Mallorca, Marrakech, La Mamora, Elvas, and Madrid, demonstrate both his adeptness in navigating the complex political and religious dynamics of Maghrebi courts and his efforts to emphasise the strategic value of the region to the grand duke.

By presenting North Africa as a key theatre for potential Tuscan diplomatic and commercial ventures, Andrea sought to align his personal advancement with the Medici’s broader Mediterranean ambitions. His correspondence combines detailed reports and policy suggestions with frequent declarations of loyalty, often couched in the rhetoric of vassalage – a reflection of the enduring bond forged during the Corsican War (1559–1569), when Cosimo I’s support for Sampiero da Bastelica had likely benefited the Gaspari family.Footnote ¹¹⁷ In this way, Andrea’s letters functioned both as instruments of self-promotion and as vehicles for projecting Tuscan influence into the western Mediterranean borderlands, revealing a grassroots form of cultural diplomacy shaped by agents operating in the Maghreb.

The earliest document attesting to the origins of Andrea Gaspari’s relationship with the Medici is a letter dated 28 January 1566, addressed to Cosimo I. Writing from Algiers, Andrea not only introduces himself as a loyal servant but immediately demonstrates the qualities that would define his role within the Florentine sphere: personal initiative, strategic foresight, and a readiness to act on behalf of Medici interests in politically volatile contexts such as the Ottoman province of Algiers. The letter highlights the central role he played in the aftermath of the capture of the Lupa – a Medici galley donated by Cosimo to the Order of St. Stephen and seized by Algerians in the summer of 1563.Footnote ¹¹⁸ Among the prisoners taken to Algiers were five knights of the Order. When Andrea learned that they were to be transferred to Constantinople by order of Hasan Pasha, the Ottoman governor of Algiers, he intervened decisively, ransoming them at his own expense. Crucially, his actions were motivated not solely by personal gain. He stressed that his primary impetus derived from devotion to Cosimo and recognition of the benevolence the Medici had long shown toward the Corsican nation. His decision was also encouraged by the pleas of the Tuscan captives and the modest expectation of eventual profit, as befitted a poor merchant relying on his own enterprise. Andrea ultimately released three of the knights – Bernardo Ridolfi, Giuliano Gianfigliazzi, and Oratio Otterio – on the condition that they would arrange reimbursement in Marseilles. Despite references to funds allegedly held by Giuseppe della Seta, a Florentine merchant active in the French port, no repayment ever materialised.Footnote ¹¹⁹

Burdened with this financial loss, Andrea addressed Cosimo I in a tone both humble and urgent, requesting not only justice but also a formal safe-conduct for himself and his men. This licence would allow them to travel securely to Medici territory, where he hoped to ‘repatriate’ and reaffirm his loyalty to the duke. More than a logistical request, the plea embodied a broader diplomatic and commercial vision: Andrea Gaspari offered his continued service in North Africa, proposing to act on the Medici’s behalf in securing horses, grain, and provisions from the Ottoman governor of Algiers. Through this appeal, he sought not merely protection but a renewed position within the Medici orbit, grounded in faithful service and shared Mediterranean ambitions.Footnote ¹²⁰

This inaugural letter established a pattern that would recur throughout Gaspari’s correspondence with Francesco I: a sustained focus on the plight of Christian captives, pursued not only with empathy but also with clear strategic intent. For example, in a subsequent letter dated March 1571, Andrea responded to a request made by Francesco in the previous autumn, seeking his assistance in securing the release of Elio Bulgarini, a Sienese Knight of Malta captured in 1570 by the Algerine corsair captain Karag Ali.Footnote ¹²¹ The letter from Francesco had reached Andrea in Algiers via Giuseppe della Seta in Marseilles – a detail that underscores how, following his successful efforts to ransom the knights of the Lupa and his earlier proposal to Cosimo I to initiate relations with Ottoman Algiers, he had come to be recognised by the Medici as a reliable and capable agent in the Maghreb.

In response to Francesco I’s request for assistance in securing Bulgarini’s release, the Corsican once again mobilised his network. Yet despite his efforts, he reported with evident sorrow that Bulgarini, along with three other Maltese knights, had succumbed to a severe fever then sweeping the region. The tone of the letter is sombre, yet it reveals much about Andrea’s self-conception.Footnote ¹²² He did not write merely as a failed negotiator, but as a faithful and devoted subject who had risked both his resources and his reputation in service to the Medici. Reaffirming his commitment, he professed his willingness to serve ‘with goods and life’, humbly entreating to be counted among the Medici’s most loyal servants. For Andrea, this was more than duty. It was a calling rooted in the longstanding devotion of his homeland to the Medici cause, a desire not only to serve the prince but also to be recognised as part of his circle of trust, both within and beyond the borders of Tuscany, as he stressed at the close of his letter.Footnote ¹²³

By the early 1570s, Andrea Gaspari’s role in the service of the Medici had become increasingly complex, extending beyond episodic interventions to encompass a broader portfolio of intelligence gathering, diplomacy, and logistical coordination. His letters from this period reveal an agent deeply embedded in the networks of Mediterranean Islamic politics, moving with fluency between Ottoman Algiers, Habsburg Spain, and Saadian Morocco, while continually negotiating the tension between personal ambition and loyal service to the Medici. For instance, in a letter written to Francesco I in July 1571 – likely following the death of Elio Bulgarini – Andrea reflected with rare emotional candour on both his personal grief and his professional sense of failure. He described Bulgarini’s death as the most painful loss he had ever experienced, not only because of the knight’s demise but also because it represented a missed opportunity to fulfil a direct request from the Medici court. Nevertheless, he emphasised his ongoing efforts by recounting the recent successful ransom of six other Knights of St. Stephen. The Corsican noted that he had supported their liberation ‘with friends, goods, and even my own livelihood’, a phrase that conveyed both material sacrifice and the moral weight he attached to his service to the Medici cause in the Maghreb. He humbly insisted, however, that even these efforts fell short of what he considered his true duty.Footnote ¹²⁴

This sense of obligation was expressed not only through political action and financial sacrifice but also through symbolic gestures that highlighted Andrea’s personal devotion and role as a cultural intermediary. Taking advantage of the travels of Leonardo dell’Elba, a merchant who was returning from Algiers to Tuscan ports, Andrea sent a selection of modest Maghrebi gifts to Francesco – a fan, damascened knives, a water flask, and two bolts of silk and wool. Although he acknowledged their humble value, these items would function as material tokens of loyalty and regional knowledge.Footnote ¹²⁵

His efforts to cultivate trust were persistent: in a 1572 letter, he mentioned his intention to procure and send North African horses to the Medici prince, explicitly noting that he had heard they would be well received, and he added a small box of dates and a hunting pouch as further gestures of loyalty, requesting that they be accepted despite their modesty.Footnote ¹²⁶ Similarly, the following year, writing from Mallorca, he confirmed the shipment of a horse through the port of Annaba, again urging that it be received ‘for love of me’ and offering to continue supplying such goods upon command.Footnote ¹²⁷ These acts, though framed with humility, aimed to position the Corsican not merely as a man of action but as a cultural broker – someone who understood Medici interests and could serve them with both goods and life. As Brian Brege has observed, these gifts epitomised a form of diplomacy that was personal, grounded, and attuned to the subtleties of local custom and Medici global ambitions. They reinforced Tuscany’s aspirations to assert itself as a Mediterranean power engaged in transcultural diplomacy and commerce, reliant on devoted agents like Andrea Gaspari to bridge courts and cultures.Footnote ¹²⁸

This phase of Andrea Gaspari’s career in the service of the Medici reached a revealing juncture with a letter dated 6 February 1574, sent from Valencia, in which the Corsican appealed directly to Francesco I for assistance in securing his departure from Spain. Having recently travelled from Algiers to the Iberian Peninsula to manage both political and personal affairs, he described the difficulties he faced as a foreigner in Spain, with limited rights and privileges in the local markets and few connections to the elite. In this context, he humbly but urgently requested a letter of recommendation – either from the grand duke himself or from the Grand Duchess Joanna of Austria (1547–1578), aunt of Queen Anna of Austria (1549–1580), consort of Philip II. By appealing specifically to Joanna, Andrea hoped to leverage this familial link to enhance the likelihood of a favourable reception at the Spanish court, thereby securing the permissions needed for himself and his brother Francesco to conclude their affairs in Spain and travel to Tuscany. Moreover, he proposed that the letter be entrusted to the Capponi brothers, Luigi and Alessandro, trusted Medici intermediaries in the Iberian Peninsula, who could ensure its safe delivery. His request was framed not merely as a personal favour but as a demonstration of loyalty and strategic utility: once released from their obligations in Spain, Andrea and his brother intended to relocate permanently to Tuscany and devote themselves fully to Medici service. He therefore assured the grand duke that their future contributions would be made ‘in deeds rather than in words’ and emphasised their enduring readiness to act on behalf of the Florentine court whenever called upon.Footnote ¹²⁹

Yet this plan for permanent relocation to Tuscany and renewed service to the Medici was quickly tempered by the realities of his Spanish experience. Just weeks later, in a follow-up letter dated 31 March 1574, Andrea conveyed a marked shift in tone and perspective. Expressing disillusionment with both the limited commercial prospects and the restrictive political climate he encountered in Valencia, he revealed that his initial hopes of settling and establishing a base in Spain had given way to frustration. Disappointed by the rigid market rules, Andrea reoriented his ambitions towards Italy – ideally Medici-controlled territory – not only to resume direct service to the grand duke but also to re-establish himself along more vital and promising trade routes in the eastern Mediterranean. He cited renewed interest in operating in Constantinople, Syria, and Egypt, which he identified as far more suitable for advancing both his commercial ventures and Medici influence. In the same letter, Gaspari disclosed that he held 5,000 ducats in Spain – funds he was unable to transfer without royal authorisation. Once again invoking the indispensable support of Medici patronage, he petitioned Francesco I to intercede by writing directly to Philip II to request the necessary royal licence. This appeal, like the earlier one, was framed not as a personal indulgence but as a necessary condition for effective and continued service. Recommending once more that the matter be entrusted to Alessandro Capponi, the Corsican reaffirmed his reliance on the Medici’s transnational networks in the western Mediterranean.Footnote ¹³⁰

Nevertheless, a decisive turn in Andrea Gaspari’s career came with a letter dated 10 February 1577, sent once again from Valencia, in which he recounted the unexpected redirection of his plans due to an urgent summons from Morocco. Although he had long expressed to Francesco I his wish to travel to Tuscany – ’ to kiss your hand and serve you with what little I possess’ – new geopolitical developments pulled him back into the western Mediterranean just as he was preparing, in late 1576, to depart for Pisa.Footnote ¹³¹ The summons came directly from Abd al-Malik, the Saadian prince exiled in Algiers and a close acquaintance from Gaspari’s time there,Footnote ¹³² who had recently reclaimed the throne of the Saadian Sultanate of Fez and Marrakech with crucial Ottoman support.Footnote ¹³³ Now firmly in power, al-Malik wrote to Andrea, urging him to come without delay to the Moroccan court to discuss matters of pressing political and commercial consequence.

His appeal was reinforced by an official mandate from the Spanish viceroy of Valencia, acting in the name of Philip II, instructing the Corsican to undertake the mission promptly to establish a channel of diplomatic communication between Madrid and Marrakech. Although eager to fulfil this commission, Andrea carefully reaffirmed his loyalty to the Medici, lamenting that, despite numerous letters, he had still been unable to travel to Tuscany as planned the previous year. Nonetheless, he assured Francesco I that, once in Morocco, he would provide regular intelligence and remain ready to act on any directive concerning Medici interests in the region. Attentive to diplomatic logistics, he proposed efficient channels for correspondence: messages could be sent via the Medici ambassador in Spain or entrusted to the Capponi brothers, both capable of routing communications through Florence, Madrid, Cádiz, and Marrakech.Footnote ¹³⁴

Although Francesco I’s direct reply to Andrea’s letter has not survived, his response can be traced in a dispatch sent to Baccio Orlandini, the Medici ambassador in Madrid. The grand duke ordered that an enclosed letter ‘for Andrea Gasparo the Corsican’ be forwarded via Cádiz to Morocco, ‘where he writes he will be travelling throughout this month’.Footnote ¹³⁵ The alignment between Andrea’s proposed itinerary and the grand duke’s implementation demonstrates the operation of a discreet yet highly effective diplomatic channel – one that enabled the Medici to maintain an unofficial presence at the Moroccan court through a semi-autonomous, yet deeply trusted, agent.

Building on this plan, Andrea’s mission in Morocco takes clearer shape in a follow-up letter dated September 1577. In it, he provided an update on his preparations and set out additional proposals that revealed the expanding scope of his role. Apologising for his recent silence – which he attributed to the absence of more instructions from Florence – Gaspari informed the grand duke that, given the strength of his relationship with al-Malik and the official character of the invitation to Morocco, he felt compelled to alert him in case any Tuscan interests might benefit from his presence in the region. In this context, he invited the grand duke to issue any instructions or commissions relevant to Moroccan affairs, reaffirming his dedication and availability as a loyal servant of the Medici. Moreover, beyond this practical offer, Andrea articulated a more strategic vision. He proposed that, should the grand duke deem it advantageous, he would facilitate the opening of formal diplomatic relations between the Medici court and the Saadian Sultanate. Confident in his rapport with al-Malik, Andrea believed he could persuade the Moroccan sultan to seek friendly ties with Tuscany – a diplomatic overture with both symbolic and material potential for advancing Medici ambitions in the Maghreb.Footnote ¹³⁶

In the same letter, Andrea further combined his diplomatic initiative with elements of cultural and material brokerage. He promised to send prized Moroccan horses – highly coveted symbols of prestige in European courts – and to provide regular reports on local political conditions. Alongside these commercial and diplomatic undertakings, he introduced a second, more personal request: support for his brother Francesco Gaspari’s recent appointment to the Order of the Holy Sepulchre. The title, likely conferred by Giovanni Antonio Facchinetti (then Latin Patriarch of Jerusalem and General Commissioner of the Holy Sepulchre), named Francesco both knight and general procurator of the Order across Spain, Portugal, and the Indies. As papal confirmation was still required for these offices to take full effect, Andrea asked the grand duke to intervene by sending letters of recommendation to his brother, Cardinal Ferdinando de’ Medici (1549–1609), urging him to address the matter with the Pope and expedite the necessary approvals.Footnote ¹³⁷

Meanwhile, the Moroccan mission, which took shape later that year, proved a pivotal moment in Andrea Gaspari’s career as an intercultural diplomatic agent operating simultaneously for the Spanish king, the Saadian sultan, and Francesco I. Upon his arrival at the court of Abd al-Malik, he entered a regime still consolidating power after years of internal conflict. His subsequent correspondence with the Medici – particularly between late 1577 and early 1578 – provides a vivid account of the Saadian sultan’s ambitions to assert Morocco’s independence from Ottoman authority and to establish himself as a sovereign Islamic power on the global stage.Footnote ¹³⁸

Particularly, Andrea’s reports detailed not only high-level political developments but also offered granular insight into court ritual and intra-elite rivalries. Crucially, he observed that al-Malik actively sought to cultivate relationships with new European powers, especially those capable of supplying military technologies and facilitating profitable commercial alliances. Rich in detail and perceptiveness, Gaspari’s dispatches positioned him as a uniquely valuable observer – able to interpret the dynamics of a court that remained largely opaque to many Christian polities. In this sense, the Moroccan mission not only consolidated his status as a trusted agent of the Medici but also exemplified a broader strategy of embedding Tuscan interests in the western Maghreb.

Although the Medici initially approached Moroccan affairs with caution – primarily because they were financially supporting King Sebastian I of Portugal’s campaign to depose al-Malik and restore his rival, Abdallah Mohammed (r. 1574–1576), to the Saadian throne – Andrea Gaspari’s proposal to Francesco I marked a significant turning point. By offering to open direct diplomatic communication with al-Malik, Gaspari encouraged the Medici to move from passive observation to active intelligence-gathering on Moroccan internal dynamics. Until then, information about Morocco had reached Florence mainly through the Medici ambassador in Madrid, Baccio Orlandini, whom Francesco I instructed to maintain contact with Gaspari during his journey to Morocco.Footnote ¹³⁹ From that moment onwards, intelligence flowed from two complementary sources: while Orlandini continued reporting from the Spanish court, Gaspari, upon disembarking in North Africa, began sending first-hand updates directly from the field.

One particularly vivid example appears in an avviso (newsletter) Andrea likely sent from Ceuta, in which he described the fragile political situation following Abd al-Malik’s recent accession. He explained that the deposed sultan, Abdallah Mohammed, had established a network of couriers spaced approximately every three leagues across the kingdoms of Fez and Marrakech to maintain secret communication with the Portuguese, in preparation for reclaiming power. When one such courier, carrying letters intended for the Portuguese-held city of Arcila, was intercepted and killed near Fez – and the contents of his correspondence seized – panic spread throughout Marrakech. In response, al-Malik staged a calculated political manoeuvre: he had forged versions of the intercepted letters read aloud during Friday prayers at the city’s main mosque. The forgeries claimed that Abdallah Mohammed was conspiring with the Portuguese king to convert Moroccans to Christianity and enslave them. By presenting himself as the guardian of Islam and Moroccan sovereignty, al-Malik successfully rallied public support, and the audience responded with vocal affirmations of loyalty, declaring their willingness to die for the Saadian sultan.Footnote ¹⁴⁰

Following that avviso, and particularly once Andrea’s diplomatic position at the court of Marrakech had been cemented through his formal reception, the Medici increasingly regarded the Corsican as a strategic asset within their broader Mediterranean policy. Andrea reported to the grand duke that he had been received with exceptional warmth by Abd al-Malik – ’ truly, had I been his own brother, he could not have treated me better’ – a reception he attributed to the bond they had forged years earlier during the sultan’s exile in Algiers. This personal rapport quickly acquired political significance: he observed that the sultan ‘greatly desired to befriend Your Highness, and in order to initiate this friendship, had written a letter to you’. From that moment, al-Malik awaited the grand duke’s response with keen interest, regarding Tuscany as a potentially valuable interlocutor in the rapidly evolving Mediterranean order.Footnote ¹⁴¹

As Gaspari noted, this letter had been forwarded to Florence via the Medici ambassador at the Spanish court. Although it appears that the message either never reached Florence or was not preserved, a telling example of the trust Andrea had earned as an informal Medici agent in Morocco is the investigation he undertook in Marrakech, at the grand duke’s request, into the background of the so-called Mule di Fes, a Moroccan slave held at the Medici’s Villa di Castello near Florence. The man claimed to be a son of the former Saadian Sultan Mohammed al-Shaykh (r. 1549–1557) and brother to the reigning Abd al-Malik. Likely concerned about the potential implications for diplomatic negotiations with the Moroccan ruler, Francesco I acted swiftly to clarify the prisoner’s identity, eager to avoid any risk of embarrassment in his dealings with the Saadian court.Footnote ¹⁴²

To that end, the grand duke issued a direct order to Andrea Gaspari, instructing him to verify the man’s lineage and report back without delay. In response, the Corsican launched a meticulous inquiry, consulting a wide range of informants to determine whether the claim had any basis in fact. He first questioned Luis Fernández, a merchant with over thirty years’ residence in the region and intimate knowledge of the Saadian dynasty. Fernández confirmed that Sultan Mohammed al-Shaykh had fathered only six sons – Muley Mohammed al-Harran, Muley Abdelqader, Muley Abdallah, Muley Abdeloumin, Muley Abdelmalek (Abd al-Malik), and Muley Ahmed – as well as three daughters: Lalla Mariama, Lalla Fatima, and Lalla Qadisha. No other children, he asserted, had ever been acknowledged. Andrea then consulted a second source: a Christian gardener known as ‘Guerrero’, who had served in the Saadian court for over four decades. Guerrero independently corroborated Fernández’s account, claiming to have known and cared for each of the sultan’s children personally. Other Christian and Muslim informants likewise denied any knowledge of the supposed claimant. Nevertheless, to ensure absolute certainty, Andrea sought a direct audience with al-Malik himself. The sultan categorically denied that the man was his relative and swore, under oath in his own faith, that his father had no son by that name. He further asserted that, if the man were truly of royal blood, he would have spared no treasure to ransom him.Footnote ¹⁴³ Andrea therefore relayed this comprehensive report back to Florence via the Medici ambassador in Madrid, assuring the grand duke that, based on every available testimony and his privileged access to the Moroccan court, the man in question was certainly not of Saadian lineage.Footnote ¹⁴⁴ At the close of his letter, he also conveyed Abd al-Malik’s expressed goodwill toward the Medici and his readiness to accommodate any future requests from Tuscany, reaffirming the sultan’s interest in fostering friendly relations with the grand duchy.Footnote ¹⁴⁵

However, the situation changed dramatically, as revealed in a letter sent by Gaspari in August 1578 from La Mamora (Mehdya). In it, the Corsican reflected on the outcome of the summer’s decisive event: the disastrous Portuguese expedition into Morocco, which culminated in the death of King Sebastian I of Portugal at the Battle of Alcácer Quibir.Footnote ¹⁴⁶ As an eyewitness to the campaign and its aftermath, Andrea offered a sobering assessment, focusing on Saadian foreign policy and strategy. He recalled how al-Malik, who had perished in the earlier conflicts against his rivals – his uncle Abdallah Mohammed and the Portuguese monarch – had genuinely sought peace with Christian powers, often expressing admiration for the ceremonial grandeur of European courts. In contrast, the new Saadian sultan, Ahmad al-Mansur (r. 1578–1603), adopted a more cautious and strategic approach toward Christian alliances.

Now, at Sultan Ahmad al-Mansur’s behest, Andrea had attempted to mediate a peaceful settlement, writing personally to the new Portuguese king, Henry I (r. 1578–1580). He explained that the Moroccan sultan sought not capitulation but a tactical partnership – one that might help limit Ottoman influence in North Africa. Yet the Portuguese king misunderstood the situation entirely. By demanding control of Larache and other strategic ports, he overplayed his hand. Al-Mansur, resolute and proud, rejected the Portuguese claims unequivocally: having won his kingdom by force, he would yield ‘not even a stone’ to the Christians – a stance he maintained even in dealings with his Ottoman allies. In a particularly striking passage, Gaspari cautioned Francesco I that Moroccan unity was firm and that any apparent openness to Christian overtures was provisional, tactical, and subject to sudden reversal. He concluded the letter by reaffirming his loyalty, declaring his intention to return soon to Valencia and placing himself at the grand duke’s disposal. As he emphasised, his reporting was a vital form of service, delivering first-hand geopolitical intelligence from within both Christian and Islamic spheres.Footnote ¹⁴⁷

However, two years later, in 1580, Andrea Gaspari was still on the Iberian peninsula. From the frontier Portuguese town of Elvas, he composed one of his most introspective and politically charged letters amid the turmoil of the Portuguese Succession Crisis. The death of Henry I had plunged the Portuguese Crown into uncertainty, with Philip II of Spain pressing his claims to the Lusitanian throne.Footnote ¹⁴⁸ Yet Gaspari’s letter to Francesco I offered more than a mere report on military movements or political rumours; it constituted a reflective, summative meditation on his years of perilous service along the fault lines of North Africa and Iberia. The Corsican recounted the risks he had endured in the Maghreb and within the Iberian world, emphasising that these were not the products of personal ambition but the inevitable hazards of a life spent executing dangerous diplomatic and intelligence missions on behalf of his patrons, both Christian and Muslim. Far from deterring him, these experiences had only deepened his desire to remain in service to the Medici, whose cause he now regarded not merely as a duty but as a vocation.Footnote ¹⁴⁹

Therefore, Andrea sought to ascertain whether his long years of loyalty – often exercised under Spanish direction – might finally be acknowledged in tangible terms. Nevertheless, he was unequivocal: whatever rewards might or might not be forthcoming from the Spanish Monarchy, his ultimate desire was to travel to Tuscany and spend his remaining years under the protection of Francesco I. His allegiance remained steadfast, grounded not in expediency but in enduring personal fidelity. To prove his loyalty to the grand duke, he identified Luigi Dovara, the Tuscan extraordinary ambassador to Madrid, as a reliable witness to his sustained commitment to the Medici court:

Such a letter, therefore, functioned both as a strategic dispatch and as a personal testament – a reflection on a life spent navigating the shifting frontiers of the early modern western Mediterranean in the service of the Medici.

2.4 Conclusions

Among Andrea Gaspari’s final and most ambitious proposals to the Medici court was a bold commercial initiative, drafted in 1587, which envisaged transforming Livorno and Pisa into central hubs of Mediterranean spice trade. Drawing on a lifetime of relationships with merchants embedded in the Iberian and Indian Ocean trading networks, Andrea informed Francesco I that a consortium of his associates had secured exclusive rights to import pepper from Portuguese India over a six-year period. Considering an increase of maritime risks in northern Europe, they proposed rerouting shipments through Tuscany, provided the grand duke could offer favourable terms and logistical support. Andrea offered to act as intermediary, presenting a practical scheme that included standardised tariffs, storage privileges, low-interest credit backed by cargo, and the potential use of Medici ships for the retrieval of goods.Footnote ¹⁵¹

Such a proposal to reroute the pepper trade through Tuscany must be understood not as an isolated venture but as a strategic continuation of longstanding Medici ambitions. For decades, the grand dukes had sought to penetrate the lucrative Portuguese spice trade, investing heavily in partnerships and even bidding directly for monopoly contracts. Although these efforts repeatedly failed during the 1570s, they laid the groundwork for renewed attempts in the 1580s. Andrea’s proposal – anchored in exclusive rights secured through his contacts – therefore emerged at a moment when the grand duchy was actively seeking to transform economic investment into political capital and diplomatic leverage. The Corsican’s plan aligned closely with the Medici strategy of using commerce not merely for profit, but to secure broader advantages: access to armed shipping, increased prestige, enhanced influence in Spain, and competition with Genoa and Venice. As Brian Brege has observed, even prior Medici bids for spice contracts were justified less by direct profitability and more by the ancillary benefits they promised: territorial primacy, reputational gains, and strengthened bargaining power within the wider Mediterranean political landscape.Footnote ¹⁵²

Therefore, more than a commercial overture, this was a diplomatic gambit. Andrea’s trans-imperial network – from Ottoman Algiers to Saadian Morocco and Habsburg Spain – provided him with unique access to strategic intelligence and trade routes. His experience reflected the hybrid roles often played by merchants and emissaries in the service of the Medici, combining commerce, intelligence, and diplomacy into a single portfolio of activity. His final project extended well beyond the pepper trade, seeking to position Tuscany at the crossroads of the western Mediterranean’s cross-cultural and commercial networks. In practice, however, it proved a failure. The grand duke showed little sustained interest, and Gaspari appeared less as an authorised agent than as an entrepreneurial adventurer advancing schemes for which no clear political appetite existed at the Medici court.Footnote ¹⁵³ Viewed alongside Gaspari’s earlier exploits – securing Medici captives in Ottoman Algiers and mediating Medici-Saadian diplomacy – this final plan reads as a culmination rather than a departure. It encapsulated his core strengths: pragmatic alliance-building, sharp commercial acumen, and intimate familiarity with both the Islamic and Christian worlds. In a manner reminiscent of the Corsican merchants of early seventeenth-century Livorno, whose investments in devotional infrastructure transformed wealth into prestige and civic belonging, Andrea sought to anchor his legacy through a proposal promising both economic and symbolic returns.Footnote ¹⁵⁴

By the time of his last known letters to the grand duke – shortly before his death in Madrid in 1590 – Andrea Gaspari had emerged not merely as a seasoned agent in the Maghreb but as a paradigmatic figure of cross-cultural diplomacy from below: a man who navigated between worlds, translated across cultures, and wielded presence and persuasion as instruments of influence. His final proposal to the grand duke thus represents not only the culmination of a remarkable career but also the crystallisation of a broader Medici strategy: projecting power through trade, intelligence, and cosmopolitan adaptability rather than through military conquest. In this respect, Gaspari’s legacy mirrors that of the grand duchy itself – ambitious, opportunistic, and perpetually attuned to the shifting currents of the early modern Mediterranean.

3.1 Introduction

Among the principal Muslim powers with which the Medici established diplomatic relations, Safavid Persia was one of the last. This was largely because, unlike the Ottomans and the Saadians (and, before them, the Mamluks), the Safavids ruled a state lying beyond the Mediterranean basin. Nevertheless, the emergence of the Safavid state marked a significant turning point in Mediterranean affairs and gradually led the Medici to establish direct contacts with it. By examining a minor ‘diplomatic incident’ that occurred in Livorno in 1610, it becomes possible to gain a synoptic perspective on Medici-Islamic relations, their complexity, their multiple layers of interaction, and their inherent ambiguities. However, this analysis requires a clear introduction to Safavid Persia and to what it represented for Medici at the beginning of the seventeenth century.Footnote ¹⁵⁵

From its foundation in 1501, when the fourteen-year-old Ismail I (r. 1501–1524) captured Tabriz, proclaimed it his capital, and declared himself shah, Safavid Persia rapidly consolidated its authority over the Iranian plateau and emerged as the principal antagonist of the Ottomans in Western Asia.Footnote ¹⁵⁶ The new state represented not only a geopolitical rival but also an ideological and cultural challenge, as it professed a form of Shia Islam characterised by a pronounced messianic dimension. This was rooted in the Safavids’ origins in a Sufi order (an Islamic mystical brotherhood), a legacy that also explains the designation by which Safavid shahs were widely known in Europe: the Sofì.Footnote ¹⁵⁷

Yet, although religious motivations played a role, the rivalry was driven above all by geopolitical considerations, including control of the Caucasus and Baghdad, the command of trade routes linking the Mediterranean to the Indian Ocean, and the broader contest for regional hegemony.Footnote ¹⁵⁸ Throughout much of the sixteenth century, the two powers confronted one another in a series of protracted wars which, although ultimately ending in Ottoman victory, nonetheless revealed to Christian Europe that Persia could serve as a potential ally against the Ottomans. Accordingly, in line with the enduring logic that ‘the enemy of my enemy is my friend’, Persia was gradually integrated into the Catholic anti-Ottoman diplomatic network.

Indeed, Persia (or rather the dynasties ruling over it) had long been regarded as a potential military partner against the Ottomans. In 1599, Giovanni Botero referred to an established tradition of amity between Christians and Persians, tracing it back to Pope Callixtus III (r. 1455–1458) and his relations with Uzun Hasan (r. 1452–1478), ruler of the Aq Qoyunlu (‘White Sheep’), a powerful Turkmen confederation that controlled much of present-day Iran and was likewise approached by Venice with an anti-Ottoman aim.Footnote ¹⁵⁹ Thus, when in 1571 Pius V (r. 1566–1572) resolved to inform Tahmasp I (r. 1524–1576), son of Ismail I, of the Catholic victory at Lepanto and to urge him to take up arms against the Ottomans,Footnote ¹⁶⁰ the initiative appeared entirely consistent with a long-standing pattern, as the Sofì had by then been integrated into the anti-Ottoman diplomatic horizon of Catholic Europe.Footnote ¹⁶¹

The successor of Pius V, Gregory XIII (r. 1572–1585), sought to revive the project of a grand anti-Ottoman alliance, embedding it within a broader programme aimed at strengthening the Roman Catholic Church. In 1584, he appointed Cardinal Ferdinando de’ Medici, brother of the Grand Duke Francesco I, as Protector of the Eastern Patriarchs and the Kingdom of Ethiopia, with the aim of bringing these communities back into communion with Rome. In the same year, Ferdinando established a printing house, known as the Tipografia Medicea Orientale, to produce Catholic texts in ‘Oriental languages’, thereby facilitating both rapprochement and missionary activity.Footnote ¹⁶² He was also entrusted with organising a diplomatic mission to the East with multiple objectives: negotiating with the Eastern patriarchs, collecting manuscripts for the press, and securing anti-Ottoman alliances with Ethiopia and Persia. The agents selected were Giovanni Battista Britti and Giovanni Battista Vecchietti (1552–1619), the latter of whom will reappear later in this study. Travelling together as far as Egypt, they then parted ways: Vecchietti remained in Alexandria, while Britti continued to Ethiopia, where his trail is lost around 1586. In 1585, Pope Sixtus V (r. 1585–1590) confirmed Vecchietti in his mission to Persia. He arrived there in the summer of 1586 and remained for about a year, dealing with Shah Muhammad Khodabandeh (r. 1578–1587). The following summer, he departed for Hormuz – under Portuguese control since the early sixteenth century – and returned to Europe via Portuguese routes, then under Spanish dominion, arriving at the end of 1588.Footnote ¹⁶³

Upon his return, Vecchietti submitted a report to Philip II of Spain on the situation in Persia, emphasising the potential benefits of dispatching skilled technicians and artillery specialists to assist the Safavids in their war against the Ottomans.Footnote ¹⁶⁴ The matter also drew the attention of Ferdinando I, who, following the death of his brother Francesco in 1587, had renounced his cardinalate to assume the grand ducal title.Footnote ¹⁶⁵ However, Philip II appears to have blocked the proposal outright, likely out of concern that an excessive strengthening of the Safavids might ultimately threaten Iberian interests in the region – particularly the island of Hormuz and its surroundings.Footnote ¹⁶⁶

Vecchietti’s mission ultimately proved unsuccessful, not least because of the logistical difficulties involved in providing military support to the Safavids, compounded by Spanish opposition. It nevertheless reopened diplomatic channels between Europe and Persia. No significant developments followed for several years. Then, in 1599, Shah Abbas I (r. 1587–1629), who had succeeded his father Muhammad Khodabandeh, and inherited a kingdom in crisis strained by war with the Ottomans in the west, Uzbek incursions in the east, and the erosion of central authority, gradually managed to stabilise his rule after a difficult decade. In this context, he resolved to send an ambassador to the King of Spain in order to pursue an anti-Ottoman alliance.Footnote ¹⁶⁷ At that moment, the English adventurer Anthony Sherley (1565–1635) arrived in Persia with his brother Robert (1581–1628). He persuaded the shah to send him to Europe as one of his representatives, with the aim of forging not only an alliance with Spain but a broader coalition among the major Christian powers.Footnote ¹⁶⁸ The embassy departed Persia in the summer of 1599 and reached Europe the following year. The envoys carried letters outlining the proposed war and related matters. Shah Abbas’ terms were clear: coordinated offensives against the Ottomans from the West and East, in exchange for free trade in Persia, freedom of worship for Christians, and permission to establish Catholic missions. The Safavid ambassadors reached the court of the Holy Roman Emperor in Prague in autumn 1600. They then proceeded to Italy, where Venice, wary of Ottoman reaction, refused to receive them. The delegation continued towards Rome, intending to proceed afterwards to Spain to negotiate with Philip III (r. 1598–1621). Before reaching Rome, however, they stopped in Tuscany and were received by Ferdinando I, remaining there for about two weeks from 16 March 1601.Footnote ¹⁶⁹

It should be emphasised that the Catholic anti-Ottoman framework outlined above became intertwined with the ambitions of Ferdinando I, who sought to strengthen his position within Italy and Europe while also loosening the constraints of Spanish-Habsburg power over his state. In this sense, relations with Persia were shaped – albeit indirectly – by the Medici’s place within the Habsburg sphere, much as in their dealings with the Ottomans. Medici-Safavid diplomacy, especially in the early seventeenth century, must therefore be understood within a dense web of interrelated factors: participation in the Spanish–Habsburg system, which provided access to wider global networks but also imposed constraints; the relative closure of the Ottoman-controlled Levant, itself part of the same geopolitical configuration; economic interests oriented towards eastern trade, notably those of the wool and silk sectors; and dynastic ambitions. All these dynamics converged in the Mediterranean space. Here too, however, constraints were significant. In the east, Ottoman dominance and Venetian commercial privileges limited access; in the west, a ‘Spanish lake’ exposed to North African corsair activity left only narrow margins for action, often reduced to the maritime practices of the Order of St. Stephen. Against this backdrop, the emergence, albeit indirect, of Safavid Persia under Shah Abbas I appeared to offer new possibilities for reconfiguring regional balances of power and opening alternative strategic horizons.

Safavid Persia appeared within the Medici horizon not as a clearly defined political entity, but as a shifting strategic reference whose significance took shape within a Mediterranean context marked by opportunity, constraint, and contingency. This section therefore approaches Medici–Safavid relations not as a linear diplomatic process, but as a sequence of episodic, interest-driven interactions situated within broader structures that both enabled and limited Tuscan engagement with the Islamic world.

3.2 Medici’s Persian Diplomacy and Mediterranean Ambitions

Against this background, the episode under consideration may be read as illustrative of both the modalities and the limits of Medici diplomatic engagement with Safavid Persia. While the introductory section has clarified the context in which Medici-Safavid relations emerged and developed, it is now necessary to examine more closely how the actions of Shah Abbas I shaped the Mediterranean context, and thus Medici diplomacy towards him.

The arrival of Safavid envoys in Florence in 1601 marked the direct encounter between Ferdinando I and Safavid Persia. Yet, beyond general expressions of goodwill regarding the war against the Ottomans, no concrete results followed. As the surviving documentation indicates, the grand ducal government did not even issue a reply to acknowledge the embassy; such correspondence was drafted only six years later, in 1607, when developments in the Levant appeared more directly advantageous to Tuscany.Footnote ¹⁷⁰

If in 1601 Persian proposals amounted largely to future promises, since the Safavids were still at peace with the Ottomans, the situation changed after 1603, when the shah launched his campaign to recover the territories lost in the war of 1578–1590.Footnote ¹⁷¹ By then, the Ottoman Empire had for several years been shaken by rebellions that undermined its stability and were widely perceived in Europe as potentially fatal to its cohesion, prompting renewed calls for a grand anti-Ottoman alliance. The same sense of crisis was evident in Persia, where the shah seized the opportunity to strike, exploiting unrest in the Ottoman provinces. Within a little more than a year, Safavid forces had recovered all previously lost territories, creating the impression in Europe that the shah might be strong enough to advance into the Mediterranean Levant, especially Syria. Many contemporaries even believed that he stood behind several of the revolts in the region or at least maintained contact with and supported the insurgents.Footnote ¹⁷²

It was precisely the Ottoman province of Syria that, at this juncture, entered Tuscan strategic calculations. The Pasha of Aleppo, Ali Janbulad (d. 1610), had risen in revolt against Constantinople, achieving initial successes but remaining in need of allies. Ferdinando I accordingly offered support, proposing to supply arms, military advisers, and logistical assistance in exchange – once victory had been secured – for commercial privileges in a prospective Syrian polity and preferential access to key ports such as Alexandretta.Footnote ¹⁷³ In the summer of 1607, Tuscan envoys departed for Aleppo, where, in early October, they concluded an agreement with the pasha. Negotiations were entrusted to Michel Angelo Corai, a dragoman from Aleppo in Ferdinando’s service.Footnote ¹⁷⁴ He was instructed not only to conduct the negotiations, but also to advise the pasha and maintain relations with Shah Abbas, whose support was considered essential for any lasting success. If necessary, he was even authorised to proceed to Persia to secure the shah’s direct involvement. To this end, the Tuscan Secretariat of State prepared detailed instructions and letters addressed to the shah, including a formal apology for the failure to respond to the Safavid embassy of 1601.Footnote ¹⁷⁵ The Syrian rebellion, however, was crushed barely twenty days after the alliance was concluded.Footnote ¹⁷⁶ Corai subsequently fled to Persia, where he remained for about four years, acting in practice as a Medici intermediary, and from where he sent several reports describing Persia, court life under Shah Abbas, major political developments, and the growing European presence in the region.

Persia entered the Medici horizon in concrete terms only when it appeared possible to harness its power to Tuscan advantage. The timing seemed propitious: with the Ottoman Empire beset by rebellions and unable to respond effectively to the Safavid offensive, an opportunity appeared to carve out a Tuscan sphere of influence in the Levant. In this context, the Medici could hope to bypass Spanish control over eastern trade routes by inserting themselves into the commercial networks linking the Indian Ocean to the Mediterranean via Persia and the Levant, thereby also challenging Venetian dominance, and by securing strategically significant territories, they might enhance their status as an assertive Mediterranean power. In this light, the attempted occupation of Cyprus in June 1607 should also be understood, undertaken as Tuscan envoys set out for Syria. Control of the island would not only have provided a base to support the pasha’s revolt but might also have enabled the grand duke to assume the royal title of King of Cyprus, to be exchanged with the King of Spain in return for recognition of his elevation to royal status in Tuscany.Footnote ¹⁷⁷

None of this would have been conceivable or even imaginable without the actions of Shah Abbas I. Indeed, a widespread European assumption held that the shah would eventually direct his forces westwards towards the Mediterranean. Such expectations point to a broader dynamic: Persia functioned in European political imagination not only as a concrete geopolitical actor but also as a constructed strategic horizon. The figure of the shah and the projection of a possible eastern offensive were shaped as much by European needs and aspirations as by Safavid intentions, resulting in a partially imagined ally whose role exceeded the realities of Persian policy.

Actually, Shah Abbas I never showed any serious intention of advancing beyond Baghdad and Iraq, regions that had previously belonged to the Persian sphere and contained important Shia shrines.Footnote ¹⁷⁸ Safavid sources offer no clear indication of any concrete plan to reach the Mediterranean. Yet in Europe the belief persisted, sustained by reports that ‘the shah would advance towards Aleppo’ – a notion that became the recurring theme of an ‘enterprise of Aleppo’ – and by claims that he stood behind revolts in the Levant, as if the insurgents were Persian proxies. This perception was further reinforced by Catholic propaganda, circulating through printed texts on Persia and the correspondence of diplomatic agents following Safavid military campaigns.Footnote ¹⁷⁹ At the same time, it is possible that Shah Abbas had an interest in sustaining such expectations, by allowing – or even encouraging – the circulation of reports concerning a westward offensive, so as to keep European attention focused on the anti-Ottoman front.Footnote ¹⁸⁰ This hypothesis, however, cannot be verified, given the near absence of Safavid sources on relations with Europe, aside from diplomatic correspondence preserved in European archives, which reveals little about the shah’s intentions.Footnote ¹⁸¹ What is clear, however, is that Safavid envoys who visited Europe in the first fifteen years of the seventeenth century consistently referred to plans for coordinated military offensives, from the East and the Mediterranean, against Ottoman Syria.

It is therefore possible that Shah Abbas I pursued a deliberate strategy in conducting his anti-Ottoman diplomacy towards Europe, characterised by the dispatch of multiple embassies in close succession – often without mutual awareness – as well as a wide array of lesser agents, such as couriers and envoys not formally authorised to negotiate.Footnote ¹⁸² Alongside the embassies sent to the main European courts (most notably Prague, Rome, Venice, and Madrid) there operated a range of more or less unofficial figures, many of whom were little more than letter-carriers. In several cases, these were merchants who, already travelling to the Mediterranean for commercial purposes, were entrusted with limited diplomatic tasks; among them, Armenians featured prominently.

In the early seventeenth century, Armenians were progressively integrated into Safavid economic and, at times, diplomatic structures.Footnote ¹⁸³ Following his 1603 campaign against the Ottomans, Shah Abbas conquered Nakhichevan and Julfa, deporting a substantial part of the Armenian population to Isfahan, where they were resettled in the suburb later known as New Julfa.Footnote ¹⁸⁴ Although the relocation involved considerable hardship – European sources in particular stress the violence of the process – the deportees were subsequently granted land and financial support, especially for activities connected to silk production and trade.Footnote ¹⁸⁵ Armenian merchants soon became key actors in Safavid commercial networks. Their caravans regularly travelled from Isfahan towards Aleppo and the eastern Mediterranean, while their broader familial and mercantile ties extended from the Indian Ocean to Europe.Footnote ¹⁸⁶ Through these networks, Armenians were also occasionally employed as informants, particularly in the eastern Mediterranean.

While this does not in itself indicate a concrete Safavid ambition to reach the Mediterranean, it does point to an awareness of its strategic importance and of the need to monitor developments in the region. It is likely that Armenian merchants involved in Levantine trade also gathered information in the course of their activities. A possible example emerges from Tuscan documentation, which records the case of an Armenian named Yovhannes, captured by the Knights of St. Stephen while travelling aboard an English ship between 1607 and 1608. Enslaved in Livorno and later released, he requested the restitution of confiscated goods, claiming that they had been provided by the shah to support him while posing as a merchant, whereas he had been engaged in intelligence-gathering on his behalf.Footnote ¹⁸⁷

The considerable number of ‘Orientals’ circulating in Europe also raised the problem of identity and identification: no easy task for Western chancelleries. In the absence of clear credentials, compounded by the ambiguity of the roles claimed by such individuals and the frequent lack of qualified interpreters at court, it was often difficult to determine their status with certainty.Footnote ¹⁸⁸ Examples drawn from Armenian cases are particularly illustrative. Individuals captured in the course of corsair activity in the Mediterranean were sometimes stripped of their possessions and, sometimes, enslaved in Livorno, only to be released once recognised as Persian subjects.Footnote ¹⁸⁹ In other cases, the issue arose more directly in a diplomatic context: in the late sixteenth century, for example, an Armenian priest visited several European courts, including the Imperial one, claiming to be an ambassador of Shah Abbas I, despite the absence of any known Safavid mission at that time.Footnote ¹⁹⁰

While in cases of capture at sea governments could justify their action, for instance, by arguing that individuals had been found aboard Ottoman vessels, the situation became more delicate when dealing with self-proclaimed diplomats. Protocol in such cases required a degree of hospitality, the exchange of gifts, and other forms of recognition. Yet the impossibility of verifying identities with certainty generated significant uncertainty. To mitigate potential diplomatic repercussions, chancelleries often adopted a cautious approach, offering modest gifts and a level of reception sufficient to avoid offence, should the visitor prove to be a genuine agent.

Of course, the problem also existed on the other side, and the most illustrative case is that of Anthony Sherley who, as already mentioned, arrived in Persia in the summer of 1599 and within three or four months managed to convince Shah Abbas I to dispatch him to Europe as his ambassador. As Subrahmanyam has noted, it remains difficult to explain why the shah was so readily persuaded by an obscure foreigner.Footnote ¹⁹¹ However, it is also worth asking what the shah had to lose by sending Sherley as his representative: if he succeeded, the shah would obtain the alliances he sought; if Sherley failed or died en route, no significant member of the court would be lost. Moreover, Sherley appears to have possessed notable military skills and a degree of personal charisma, and it is also possible that he misrepresented his credentials.Footnote ¹⁹² In any case, the shah’s decision likely reflects a Safavid inclination towards realpolitik and a willingness to seize any available opportunity, in ways not dissimilar from their European counterparts.

Overall, the Medici opening towards Persia retained a strongly utilitarian character, closely aligned with the broader ambitions of Ferdinando I, for whom Persia represented only one of several possible strategic options. Ambition, Mediterranean geopolitics, problems of identity and identification, diplomacy, conflict, and linguistic and cultural mediation, as well as the limits of Tuscan diplomatic capacity, converged in exemplary fashion in a single episode happened in 1610 in Livorno.

3.3 Khaje Safar and His Negotiations for the Shah

The embassy of March 1601 was followed by another in the late summer of 1609, this time led by Robert Sherley, younger brother of Anthony, which served to re-establish contacts.Footnote ¹⁹³ Through Sherley’s mission, several letters from Shah Abbas I reached Florence, including references to Michel Angelo Corai and his arrival in Persia, where he had taken refuge following the defeat of Ali Janbulad in late 1607. Corai, who had travelled to the shah with the declared aim of encouraging him to assist the pasha of Aleppo in recovering territories lost to the Ottomans, was subsequently retained in Persia until 1612.

Then, in the final days of December 1609, news reached Florence of the unexpected arrival in Livorno of an Armenian claiming to be a Persian ambassador. His landing brought together many of the issues outlined in the preceding pages. Uncertain how to proceed, local authorities followed established protocol while awaiting instructions from the Secretary of State, Belisario Vinta, and from Cosimo II (r. 1609–1621), who had become grand duke after the death of Ferdinando I. The man carried a letter in Persian along with other documents, presented himself as an envoy of Shah Abbas I, and, being a Christian, had attended Mass.Footnote ¹⁹⁴ Through a friar who accompanied him, it was also understood that he spoke of the possibility of joint action against Aleppo.Footnote ¹⁹⁵

The agent’s name was Khaje Safar, an Armenian belonging to the mercantile milieu discussed above, on which the shah had come to rely extensively. Yet his arrival immediately raised the problem of his identification. In the absence of an interpreter capable of translating his Persian credentials, on 5 January 1610 Vinta forwarded the documents to Giovanni Battista Vecchietti in Rome, enclosing a letter that outlined the situation and requesting his assessment of whether the man should be received and, if so, what his actual rank might be. Vinta’s letter clearly reveals how common it was for ‘Oriental’ figures to appear at European courts claiming diplomatic status without necessarily possessing it; he explicitly warned against allowing the Tuscan court to become a destination for false ambassadors, given that the reception of an envoy entailed significant ceremonial obligations and costly gifts.Footnote ¹⁹⁶

Problems of identification had already arisen at every port where Khaje Safar had stopped before reaching Livorno. He had travelled overland to Alexandretta, from where he embarked on a French ship bound for Marseille, before proceeding to Genoa; in both cities he had been detained on suspicion of espionage.Footnote ¹⁹⁷

On 12 January 1610 Vecchietti sent his translation of Khaje Safar’s credentials together with a letter explaining the case.Footnote ¹⁹⁸ His translation confirmed the Armenian’s identity as the son of Cuge Jadigar and thus suggesting a connection with circles close to the Safavid court.Footnote ¹⁹⁹ The term yadigar, as noted by Zekiyan, appears to be linked to the class of merchant-agents discussed above,Footnote ²⁰⁰ and this case parallels that of the Armenian merchant enslaved in 1607 who had likewise sought to establish his credentials by claiming close ties to the shah’s household.Footnote ²⁰¹ Finally, Vecchietti clarified that the name Khaje (Cuge) was in fact a title (khwaja) commonly associated with merchants, a detail that further reinforced the credibility of the man’s claims.Footnote ²⁰²

Vecchietti also clarified the purpose of Khaje Safar’s journey. Some years earlier, a merchant named Fathi Beg had been dispatched to Venice to procure goods on behalf of Shah Abbas I. On his return through the Levant, however, the outbreak of hostilities between the Safavids and the Ottomans forced him to interrupt his journey, and the merchandise was consequently sent back to Venice, where it remained awaiting further instructions. Khaje Safar’s task was to recover these goods: he was to travel from Alexandretta to Venice, then proceed to Florence and Rome, before continuing on to Spain and ultimately returning to Persia.Footnote ²⁰³

However, Vecchietti also observed that it was unlikely the shah would entrust a mission of such secondary importance to a fully accredited ambassador, as Khaje Safar claimed to be. He considered it more likely that the Armenian was a merchant pursuing his own affairs, to whom the shah had opportunistically entrusted a secondary task. Accordingly, Vecchietti concluded that there was no need to treat him as a formal ambassador, but rather to accord him the minimum degree of honour and respect required to avoid protest and preserve the grand duke’s reputation, namely, a decorous reception, proportionate gifts, and assistance.Footnote ²⁰⁴

The assistance envisaged by Vecchietti included not only the provision of funds, if necessary to cover travel expenses, but also letters of recommendation that Khaje Safar could present at other European courts, thereby facilitating his passage and reducing potential problems of identification. It was no coincidence that the Armenian had been sent to Tuscany: the shah’s letter was addressed to the grand duke, requesting that he provide his envoy with support in his dealings with the Venetian authorities. Instructions were likewise sent to the Tuscan ambassador in Venice to assist him as required.Footnote ²⁰⁵ In this sense, if the embassy of 1601 inaugurated relations and that of 1609 reaffirmed them, Khaje Safar’s visit in 1610 may be seen as consolidating the favourable state of relations between the Safavids and the Medici, as well as confirming the latter’s place within the Safavid diplomatic horizon.

Khaje Safar subsequently travelled to Venice and then to Rome, before returning to Florence in late summer. At the end of August, while in Livorno, he claimed to recognise a few captives as Armenian Christians subjects of the shah and immediately requested both their release and the restitution of the goods confiscated at the time of their capture by Tuscan forces. This request prompted a reaction from the Tuscan government that merits closer examination.

On 1 September 1610, Belisario Vinta wrote to the Governor of Livorno, reporting that the ‘King of Persia’ had requested the release of ‘those Armenians, or Persians, and a very old woman, who are some slaves’, and that the grand duke had agreed to grant this request.Footnote ²⁰⁶ The governor was therefore instructed to set them free immediately. Vinta described the act as a ‘work of charity’ adding that the grand duke expected the individuals to be treated with compassion – likely implying that they should be provided with sufficient means to facilitate their return to Persia. Attached to the letter was the list of the persons to be released.Footnote ²⁰⁷

In reality, the request had been made by Khaje Safar himself, who invoked the shah’s authority to secure their liberation. Again, this case raises a number of questions, particularly concerning the identification of the individuals and the credibility of their claims. It is noteworthy that, in Vinta’s letter, they are described as ‘Armenians, or [i.e.] Persians’, a formulation that reflects the fluidity between cultural–religious and political belonging: they were Armenians, and thus Christians, yet ‘Persian’ insofar as they were subjects of the shah.

As noted above, it was not uncommon for Armenian merchants to traverse the Mediterranean for commercial purposes, nor for them to be present in Livorno, where a significant community developed over the seventeenth century, composed of individuals originating both from the Ottoman Empire and Safavid Persia, each maintaining its own representatives and places of worship.Footnote ²⁰⁸ This mobility, however, exposed them to the risks associated with corsair warfare, particularly the Catholic one.Footnote ²⁰⁹ Although it was relatively uncommon for Christian merchants to be enslaved, those found aboard Ottoman or otherwise non-Catholic vessels were often stripped of their goods, even if not deprived of their freedom; similarly, ships owned by Christians could be subject to confiscation if Muslim merchants were discovered on board. Several examples illustrate this pattern. The Armenian Yovhannes, mentioned above, was captured and dispossessed while travelling on an English ship.Footnote ²¹⁰ Likewise, in the following year, Thomas Glover (English ambassador to Constantinople between 1606 and 1611) reported that an Armenian merchant named Abraim was seeking the restitution of goods seized by the Tuscan navy, as detailed in an inventory attached to his petition.Footnote ²¹¹ Unlike others, however, he had not been enslaved.

The distinction between enslavement and mere confiscation could depend on whether individuals were identified – or misidentified – as ‘Turks’, that is, as Muslims or Ottoman subjects; in Livorno, such cases of mistaken identity were likely frequent. Although norms governing corsair warfare did exist – notably the principle that Christians should not be enslaved – they were not always observed.Footnote ²¹² Particularly in the eastern Mediterranean, the boundaries of legality were fluid, and Catholic corsairs, including the Tuscan Knights of St. Stephen, did not invariably adhere to official guidelines, as the cases cited above demonstrate.Footnote ²¹³

The presence of Armenian slaves who were subjects of the shah was therefore not unusual, nor was it uncommon for the grand duke to order their release once their Christian identity or their allegiance to Persia had been established. In this respect, it is notable – and striking in terms of timing – that, while Khaje Safar was in Italy, Florence received one of the first letters sent by Michel Angelo Corai from Isfahan. Among other matters, the letter addressed the liberation of Safavid Armenian subjects and even mentioned Khaje Safar’s mission, noting that he had been entrusted with a letter for the grand duke.Footnote ²¹⁴ In the summer of 1610, around June, Friar Vicente de San Francesco, a Discalced Carmelite and one of the early papal missionaries to Persia, was also present in Florence.Footnote ²¹⁵ Having travelled to Europe in 1609 to deliver letters from the shah to the pope, he had been entrusted by Corai with a letter addressed to Curzio Picchena, one of the principal secretaries of state alongside Vinta.Footnote ²¹⁶ In this letter, Corai reported that Shah Abbas had learned of Ferdinando I’s decision to release certain Armenian subjects captured by the Knights of St. Stephen and had expressed great satisfaction at the news.Footnote ²¹⁷

Thus, the situation generated by Khaje Safar was not unprecedented; the novelty lay in the fact that the request for the Armenians’ release was advanced by an agent explicitly acting in the shah’s name, prompting a more formal response from the grand ducal government.

Although Tuscany had been in official contact with Persia for roughly a decade, relations remained sporadic, albeit cordial. As noted above, the Tuscan government did not send letters to the shah until 1607; when it eventually did so, the Secretariat of State, lacking familiarity with appropriate diplomatic formulas, appears to have drawn on models used in correspondence with the Ottoman sultan, with whom more established relations existed.Footnote ²¹⁸

In any case, at least two letters were drafted in 1610: one, dated 13 August, expressing gratitude for the dispatch of the shah’s agent and reaffirming friendship;Footnote ²¹⁹ the other, dated 1 September, addressing the issue of the Armenian captives.Footnote ²²⁰ The tone of this second letter remains formally amicable, as required by diplomatic convention, yet it also reveals a certain irritation on the part of Cosimo II at being compelled to comply with the request of a Safavid agent. This tension emerges clearly in several passages, which merit quotation in full:

As already noted, while diplomatic conventions are formally respected, three elements reveal underlying tension. The first concerns the legitimacy of the Armenians’ capture and the handling of their ransom; the second, the refusal to return confiscated goods; the third, the suggestion that the shah should in future provide clearer credentials for his subjects.

Regarding the first point, one enters the complex terrain of what might be termed the ‘rules of engagement’ of Mediterranean privateering. Cosimo II presents the prisoners’ release not as an obligation but as an act of grace: in his view, their capture occurred in full accordance with shareed norms, and their release therefore constituted an exceptional favour. The gesture implicitly positions him in a stance of moral (likely implicitly Christian) superiority, granting clemency to an allied yet Muslim sovereign.Footnote ²²² Cosimo addresses the shah as an equal, without acknowledging hierarchical superiority, likely reflecting a reluctance to confer additional prestige on a Muslim ruler. Conversely, Shah Abbas I, like other Safavid shahs, tended to regard non-Muslim rulers as inferior to major Islamic sovereigns such as the Ottoman sultan or the Mughal emperor, even when these were his adversaries. Within Europe, however, he showed a clear preference for engaging with the monarchs of major kingdoms (France, England, and Spain) rather than with lesser rulers such as a grand duke.Footnote ²²³ In this context of mutual asymmetry, Venice stands out as an exception: despite its limited territorial base, it was recognised as a major actor and a valuable military and commercial partner.Footnote ²²⁴

The issue is further complicated by the notion of ‘legitimate prize’ through which both the capture of prisoners and the seizure of goods were framed as lawful. Yet behind this justification lay more pragmatic motives, including profit through plunder and ransom – as well as dynastic and commercial interests, as discussed above.Footnote ²²⁵ Even if the confiscated goods had been dispersed and were no longer recoverable, the grand duke would in any case not have considered himself obliged to return them, since they were regarded as legitimate spoils of war – even when belonging to subjects of a friendly power.

Finally, it must be noted that Tuscany operated within the constraints of the Spanish–Habsburg system, which limited its diplomatic autonomy in comparison with powers such as France or Venice. As a Catholic ruler, vassal of both the Holy Roman Emperor and the King of Spain, and Grand Master of the Order of St. Stephen, Cosimo was expected to conform to the model of a ‘crusading prince’. In this light, structural limitations of Medici diplomacy towards the Islamic world(s) become evident. Whether in relation to the Ottomans or Safavid Persia, Tuscan policy tended to operate within predefined frameworks, often failing – or refusing – to engage fully with the internal diversity and distinct political logics of the Islamic polities involved.

The third point raised by Cosimo II concerns the identification of the shah’s subjects. While the broader question of identity in the early modern period lies beyond the scope of this section, the grand duke’s position on this issue is nonetheless significant. Cosimo advises – indeed implicitly urges – Shah Abbas I to ensure that his merchants carry documentation attesting both to their Persian origin and their status as his subjects. Such certification, he suggests, would enable Tuscan soldiers to verify identities and avoid arrests or confiscations. This proposal, however, rests on problematic assumptions. It presupposes a system of standardised documentation that could be systematically issued to mobile merchant communities. In practice, early modern mobility relied on ad hoc instruments (safe-conducts, letters of passage, and commercial credentials) rather than uniform identification systems, making such a scheme difficult to implement.Footnote ²²⁶ Moreover, the effectiveness of such credentials in the context of corsair warfare is doubtful. Even if produced, they would need to be examined (and understood) during maritime inspections conducted under uncertain conditions. In absence of a skilled dragoman, documents in Persian would in most cases have limited practical value.

Beyond these practical constraints, Cosimo’s argument reveals a deeper conceptual misalignment. His reasoning reflects a distinctly European logic of political belonging, in which merchants are clearly defined as subjects of a sovereign and can be identified through formal documentation. By contrast, Safavid, and more broadly Islamic, frameworks did not operate according to equivalent categories of territorial subjecthood but relied on different legal and social distinctions.Footnote ²²⁷ The expectation that Safavid merchants should be legible within Tuscan categories thus imposed an external model that did not necessarily correspond to Persian realities.

In this light, Cosimo’s remarks appear less as a practical solution than as a rhetorical strategy shifting responsibility onto the shah. By attributing the incident to the absence of proper certification, he effectively shifts responsibility onto the shah, implying that the arrests and confiscations resulted not from Tuscan practice but from deficiencies on the Persian side. As in the preceding points, this reasoning allows the grand duke to preserve diplomatic courtesy while simultaneously avoiding any acknowledgment of fault.

3.4 Conclusions

As suggested in the introduction, Medici diplomacy towards the Islamic world was not structured as a coherent or sustained policy but rather unfolded through fragmented and situational engagements. The episode examined here confirms this pattern, revealing how even minor interactions were shaped by contingent interests, limited institutional tools, and asymmetrical frameworks of interpretation.

Shah Abbas I remained unaware of the affair for nearly a decade. Khaje Safar never returned to Persia, and the letters addressed to the shah reached Isfahan only in 1619 through the Spanish ambassador.Footnote ²²⁸ Once they arrived, the shah asked the Discalced Carmelites to translate them; given the linguistic difficulties, the friars sought the assistance of the Roman traveller Pietro Della Valle (1586–1652), then in Isfahan and directly involved in their interpretation.Footnote ²²⁹

Although Cosimo II’s letter had no tangible impact on relations with Persia, as it responded to a situation that had not fully materialised, the episode remains significant. It shows how even a minor and indirect interaction could activate diplomatic mechanisms and expose underlying assumptions, as an ambiguous situation was nonetheless treated as a matter of sovereign-to-sovereign relations. What emerges is a specifically Tuscan approach shaped by structural constraints. Persia, in this sense, was not simply encountered, but also interpreted and, to a significant extent, constructed through Tuscan categories and expectations. Unlike powers such as Venice or France, Tuscany operated within the Spanish–Habsburg system and remained tied to the ideological and institutional logic of crusading orders such as the Knights of St. Stephen. This context helps explain both the tone of Cosimo’s response and the rigidity of the conceptual tools he employed, grounded in categories drawn from his own political and maritime environment – above all privateering, legitimate prize, and the hierarchical management of subjecthood.

The three key issues raised in the letter – legitimacy of capture, restitution of goods, and documentary proof of identity – highlight these limitations. In each case, Cosimo framed the problem within a normative system he assumed to be self-evident, yet one that was neither universal nor necessarily legible within the Safavid context, which operated outside Mediterranean dynamics.Footnote ²³⁰ The suggestion that Persian merchants should carry documentation proving their status reflects a Western logic of political belonging that did not fully correspond to Safavid or broader Islamic legal and social distinctions, while its practical feasibility – given linguistic barriers and maritime realities – remained doubtful.

Rather than signalling a simple failure of communication, the episode points to the limited development of Tuscan diplomatic practice vis-à-vis Islamic powers. The issue was not the impossibility of mutual understanding, but the absence of the tools or sustained incentive to pursue it more deeply, especially given Tuscany’s relatively marginal position compared to the major European powers with which the shah maintained more continuous contact.Footnote ²³¹

A particularly illuminating counterpoint is provided by Della Valle, whose observations, written while he was in Isfahan and assisting in the translation of these letters, offer an almost contemporary critique. Reading Cosimo’s letter in the Safavid capital, Della Valle exposes the contradictions underlying the grand duke’s claims: what Tuscan authorities presented as lawful warfare and clemency appears instead as maritime predation cloaked in religious justification. He notes how the rhetoric of ‘just war’ legitimised the plundering not only of Muslims but also, and very often, of Eastern Christians such as Armenians.Footnote ²³²

Even more striking is his reflection on the condition of these communities. Far from being protected by shared faith, they appear doubly vulnerable: subject to hardship within Ottoman domains and exposed to capture by Catholic corsairs. His remarks implicitly challenge Cosimo’s third argument, suggesting that documentary proof of allegiance would have done little to address the underlying problem, namely, that religious identity alone did not guarantee protection in a system driven as much by profit as by confessional ideology. In this sense, Della Valle’s perspective highlights the gap between normative justifications and lived practice.Footnote ²³³

This episode thus underscores both the possibilities and the limits of early modern diplomatic interaction. While broader strategic objectives – such as anti-Ottoman cooperation – could foster convergence, more specific issues revealed the fragility of that alignment. Cultural frameworks, institutional constraints, and asymmetries of power shaped how actors interpreted and managed even minor incidents.

Ultimately, the significance of the case lies less in its immediate consequences than in what it reveals about Medici diplomacy. Persia was not approached as a fully understood partner, but as a resource within a broader Mediterranean strategy. The resulting interactions were functional and, at times, effective, yet consistently marked by a tendency to interpret the Safavid world through Tuscan categories and priorities. In this sense, the episode illustrates not a breakdown of diplomacy, but its operation within clearly defined – and equally limited – horizons.
