Adolfo Polo y La Borda presents a novel exploration of imperial officials who shaped and sustained the Spanish Monarchy between 1580 and 1700. Framed by a holistic approach to the question of political identity—Spanish cosmopolitanism—this work goes beyond the local level and invites us to rethink colonial governance, mobility, and global identities as integral to understanding how a global empire functioned in practice. Polo y La Borda’s dual focus on officials’ mindsets and institutional mechanics offers a rich analytical framework (6), which expands the field by revealing how individuals both navigated and embodied the moving structures of imperial power.
Polo y La Borda’s core thesis is that the Spanish Empire was held together by the movement of imperial officials and their ability to operate across space, culture, and law. He argues that, despite the geographic discontinuity of imperial holdings, these officials conceived of the Spanish empire as a coherent whole, a notion forged through their mobility, administrative experience, and daily engagement with diverse peoples and realities (2, 4). Far from passive bureaucrats, these actors were “global servants,” who adapted governance to local conditions while sustaining the empire’s overarching logic (6, 12, 19). Global Servants stands alongside recent scholarship on imperial distance (e.g., Guillaume Gaudin and Roberta Stumpf) and localized globalities (e.g., Antonella Romano).
The author’s methodological emphasis on mobility provides a strong foundation for future work on the lived dynamics of global governance. This is neither conventional political history nor a singular biography; it is a carefully constructed serial microhistory. Through vivid case studies, Polo y La Borda traces how individuals’ experiences of mobility shaped both their sense of cosmopolitan identity and the imperial policy they served. His approach is innovative, blending institutional analysis with biographical detail to study “how power was enforced” across a fragmented world (12).
Although the book covers a period from 1580 to 1700, its thematic structure prioritizes central tensions such as mobility versus control and identity versus empire, rather than a linear narrative. In Chapter 1, “An Empire on the Move,” Polo y La Borda argues that mobility was foundational to Spanish imperial rule. He examines how officials’ movements shaped identity, how distance influenced governance, and how fragile infrastructures and new technologies enabled global circulation. Cases such as that of Ordóñez de Cevallos demonstrate that imperial power relied on orchestrating and imagining movement across vast geographies. Building on this, Chapter 3, “An Empire of Experts,” explores how direct experience became the currency of merit (131–2). Here, Polo y La Borda skillfully illustrates how officials codified and narrated their careers through documents such as informaciones de mérito y servicios (135, 160), contributing to a dynamic epistemology of governance.
Shifting to a more confrontational terrain, Chapter 4, “Controlling Dissent and Imposing Authority,” explores how imperial officials navigated rebellion and disorder across the empire, from Chile and Manila to Córdoba (Andalusia, Spain) and Oaxaca. Polo y La Borda underscores how mobility facilitated the physical enforcement of power and the construction of a shared imperial vision of threat, rooted in a Catholic ethos of universal authority (167–201). Particularly illustrative is the well-known case of the Spanish–Mapuche conflict and the figure of procurador Alonso González de Nájera, echoing recent studies in Colonial Chilean historiography by Miguel Donoso and Rafael Gaune. Through this lens, the chapter offers a nuanced understanding of the inclusion and exclusion of various people, whether moral, political, or religious, enriching the broader narrative of how imperial authority was imagined and enacted.
Chapter 5, “Radical Mobility,” explores how excessive or culturally transgressive movement by Spanish officials, such as Pedro de Bohórques and Diego Romero, who adopted Indigenous roles, provoked fears about imperial identity loss. This “radical mobility” exposed the fragile limits of Spanishness, prompting institutional responses, particularly from the Inquisition, to define and police acceptable identity and behavior within the empire (206). Chapter 6, “Imperial Cosmopolitanism,” then proposes that the imperial worldview was forged from below by mobile officials at the peripheries. These “world-makers” navigated multiple loyalties and cultures, constructing a functional, though contested, cosmopolitanism (242–8). Polo y La Borda analyzes examples such as Guaman Poma de Ayala’s writings, the linguistic diversity of cities such as Mexico, and exchanges from Madrid to Paraguay, demonstrating how local and global narratives overlapped in the Spanish imperial imagination (275, 283). While the content flows clearly, Chapter 6 might have functioned more effectively as an opening framework for the subsequent case studies rather than as a conclusion, offering a compelling lens through which to read them.
Thematically, the book centers on politics, mobility, and cosmopolitanism, while also addressing identity, hybridity, and gender, particularly women’s influence in patronage (10, 94). The book raises intriguing questions about the political role of cities in shaping cosmopolitan identities. A future project could explore how global outlooks emerged from urban centers, even without physical mobility. Might cosmopolitanism arise from life in a globally connected city, even in the absence of physical travel? Could an individual rooted in such a place still embody the role of a cosmopolitan servant? These questions remain open.
The book draws on a remarkable breadth of archival sources from across the empire. Its methodological strength lies in the juxtaposition of seemingly disparate individual trajectories to reveal underlying systemic patterns. Although certain historical figures may seem exceptional, the author employs them as agents to illuminate broader dynamics of imperial service (20). That said, a fuller explanation of how and why the author selected these case studies could increase the book’s value by making clearer the balance between extraordinary and ordinaries examples. Moreover, a more explicit classification of the sources, for example, a distinction between manuscript and print, or between legal texts and personal documents, could have brought greater clarity to the interpretive nuances in the analysis.
Global Servants offers a significant and original contribution to studies of the Spanish Empire and early modern globalization. Its clarity, narrative depth, and global scope will benefit scholars of empire, mobility, and political culture, while its case-based structure and helpful maps ensure accessibility for students and general readers. Although focusing on mobile, literate officials—those leaving archival traces—the author demonstrates an acute awareness of historical visibility’s limits and the archive’s constraints, thereby underscoring microhistory’s narrative value.
In sum, Polo y La Borda’s meticulously researched and analytically rigorous study offers a timely contribution to scholarship on imperial governance and global mobility in the Spanish world. His conclusion underscores this history’s contemporary relevance, showing how early systems of global mobility and politics sustained the ideal of a universal monarchy (290). Far from passive bureaucrats, Spanish officials served as “the empire’s skeleton” (292), redrawing the early modern world’s geographic and conceptual boundaries through their movements and decisions. In an age marked by global mobility, transnational administration, and competing claims to universal authority, Global Servants provides both a powerful account of the Spanish Empire and a lens for reflecting on the foundations of global governance today.
