Reconsidering the nature of the so-called Aristoteles Decree, our single most important source for the Second Athenian League, which was Athens’ military alliance in the fourth century, casts a new light on the old question of whether the League was a new edition of the fifth-century Athenian empire and illuminates some of Athens’ imperialist policies after her demise in the Peloponnesian War. The closely interconnected topics examined in this article are the nature of the Aristoteles Decree and the status of Athenian allies.
1. THE ARISTOTELES DECREE
Diodorus and Xenophon are our two main literary sources for the events surrounding the League’s origins. Diodorus’ much more detailed account is significantly later than Xenophon’s text. There is good reason, however, to believe that Diodorus’ source regarding the League’s foundation was Ephorus, a fourth-century historian.Footnote 2 While not consistently reliable, Ephorus at least could claim to be a contemporary of the Second Athenian League, as was Xenophon (whose reliability cannot always be taken for granted either). According to Diodorus, after the liberation of the Cadmea and Thebes from Sparta in the winter of 379/8 (which Diodorus dates to 378–377),Footnote 3 Athens sent envoys to Greek city-states under Spartan control with an appeal to ‘hold on to the common freedom’.Footnote 4 Then, continues Diodorus, the Athenians established a common council (the synedrion) of all the allies in Athens, and ‘the Athenians and the rest of the Greeks who participated in the council were allied with the Thebans’.Footnote 5 Diodorus says that, after Sphodrias’ failed attack on the Piraeus in March 378 (which Diodorus dates to 377, referring to him as Sphodriades), the Athenians declared war on Sparta, ‘admitted the Thebans into the synedrion on terms equal in all respects’, and ‘voted to restore the land settled by cleruchs to its former owners and passed a law that no Athenian should cultivate lands outside of Attica’, thus securing the goodwill of the Greeks who eagerly accepted Athens’ leadership.Footnote 6 Xenophon begins his account with the recovery of the Cadmea from the Spartan garrison by the Thebans with Athens’ help and continues with the failed raid of Sphodrias (using this name, now commonly accepted) and his trial and acquittal in Sparta, after which the Athenians ‘gave aid to the Boeotians with all zeal’.Footnote 7
The Aristoteles Decree—an inscribed Athenian decree moved by Aristoteles of Marathon and adopted in the seventh prytany of Nausinicus’ archonship (February–March 377)—is typically interpreted as the League’s founding document.Footnote 8 The Decree (IG II2 43.15–25), however, merely proclaimed the principles on which the Greeks could join Athens and her allies:
If any of the Greeks or of the barbarians living in Europe or of the islanders, who are not the King’s, wishes to be an ally of the Athenians and their allies, he may be—being free and autonomous, being governed under whatever form of government he wishes, neither receiving a garrison nor submitting to a governor nor paying phoros, on the same terms as the Chians and the Thebans and the other allies.
Opinions on the date of the League’s establishment have diverged. Some believe that its foundation occurred following the liberation of the Cadmea in the winter of 379/8 and that it preceded, and precipitated, Sphodrias’ attack on the Piraeus. Others date the beginning of the League to the autumn of 379, that is, even before the recovery of the Cadmea and the liberation of Thebes.Footnote 9 The majority opinion sees the League’s foundation as a consequence of Sphodrias’ attack and dates it to the period from that attack (March 378) to the adoption of the Aristoteles Decree (February–March 377).Footnote 10 However, Diodorus mentions Athens’ appeal to the Greeks in the name of ‘common freedom’ (from Sparta) after the liberation of the Cadmea, and speaks of Thebes as becoming an ally of Athens and her League at that time before noting that Thebes joined the League in connection with Sphodrias’ raid.Footnote 11
As to Thebes’ League membership, one may question the universally accepted explanation of Diodorus regarding why Thebes joined the League while keeping his suggested date of that event. Why should the Thebans, who already were the allies of Athens and the League, wish to be admitted into the League’s synedrion—acknowledging Athens’ supremacy and (formally) forsaking their nascent hegemony over Boeotia—after Sphodrias’ hapless attack on the Athenian Piraeus? The probable reason Thebes joined the League was Agesilaus’ incursion into Boeotia in the spring of 378. Not as famous as Sphodrias’ raid, it posed a real danger to Thebes’ independence and, as the Thebans should have rightly suspected, established a pattern for such incursions in the future.Footnote 12 Responding to Agesilaus’ attack would give the Thebans enough time to join the League before the adoption of the Aristoteles Decree in February or March 377. Xenophon, who disliked the Thebans, says nothing in the Hellenika about Thebes’ membership in the League (which may not necessarily mean much since Xenophon ignored mentioning the foundation of the League in the first place),Footnote 13 while noting, in the Poroi, that the Thebans ‘handed the leadership over to the Athenians having profited from their good services’. The latter might relate to Xenophon’s description of Agesilaus’ raid into Boeotia in 377, which casually mentions the presence of Chabrias, who was in charge of the Athenian force on the Theban side. In the following year, the Spartan raid into Boeotia was curtailed once its leader, Cleombrotus, saw both the Thebans and the Athenians guarding the road.Footnote 14 The military cooperation between Athens and Thebes in 377 and 376 appears to have been based on Thebes’ membership in the League. Briefly, then, the League should have been in place at some time after the liberation of the Cadmea (winter 379/8), when the Athenians appealed to the Greeks to join in a fight for freedom against Sparta and when the Thebans allied themselves with Athens and the League, and before Agesilaus’ raid into Boeotia (spring–summer 378), when the Thebans became members of the League. There is no direct indication of an earlier date of the League’s foundation.
Establishing the moment of the League’s foundation also depends on understanding how it came into being. The usual view has been that its foundation, as summed up by Ruzicka, ‘represented the augmentation of an already existing συμμαχία comprising Athens, Rhodes, Chios and Byzantium’, meaning that the existing bilateral alliances formed the ‘core’ of the League. According to Tuplin, the foundation of the League ‘involved converting several existing bilateral alliances into a system which eventually offered special rights’ to the members of the League.Footnote 15 However, Athens was not a member of the League, nor did it have a seat in the League’s synedrion—documents mention the Athenians side by side with their allies when decisions were being made and oaths were being swornFootnote 16 —nor did bilateral treaties constitute a comprehensive alliance.
Arguing from parallels between ancient and modern developments might sometimes be illuminating. For instance, the European Union’s formal predecessor, the European Coal and Steel Community (1952–2002), did not just expand into the European Union via augmentation: representatives of its founding countries (France, Belgium, West Germany, Italy, The Netherlands and Luxemburg) signed a new agreement, the Maastricht Treaty, in 1993, together with the other six members of the European Communities—in the same way as the countries that would be joining later. The requirement for a separate procedure and treaty explains why the European Coal and Steel Community formally coexisted with the European Union for another decade. Something similar might be suggested for the Second Athenian League: while it relied on the practice and principles of Athens’ earlier bilateral agreements with individual Greek states, the latter made new treaties when they joined the League, just like the states which became its members later. For example, Thebes first formed an alliance with Athens and the League and then joined the League’s council.Footnote 17 Accame, Burnett, Rice, Cargill, Buckler and (tentatively) Occhipinti believe that Athens and Thebes made two treaties and that the second sealed Thebes’ membership in the synedrion.Footnote 18 Whether this second treaty was the lacunose inscription containing Athens’ treaty with Thebes is uncertain.Footnote 19
Diodorus’ reference to Chios and Byzantium as ‘the first to change sides’ in response to Athens’ appeal that ‘the cities which were subject to the Lacedaemonians’ should adhere to ‘the common cause of liberty’ following the liberation of the Cadmea similarly suggests that those cities made new agreements with Athens, because Chios already had a treaty of mutual protection with Athens,Footnote 20 and Byzantium’s treaty with Athens from 378 allegedly included a (restored but universally accepted) clause that the Byzantines would form an alliance with Athens and other allies (which does not mean membership in the League) ‘on the same terms as the Chians’.Footnote 21 Mytilene and Thebes followed later but still before the adoption of the Aristoteles Decree: these cities were inscribed by the same hand as the main document, as opposed to those whose names were added subsequently.Footnote 22 Other Athenian allies similarly changed their status, as evidently did Methymna, whose treaty with Athens from 377 b.c. included the following clause (IG II2 42.11–16):
Concerning what the Methymnaeans say, since the Methymnaeans are allies and well disposed to the city of Athens, so that their alliance may be with the other allies of Athens also, they shall be written up by the secretary of the council, as the other allies have been written up also.
Methymna then swore oaths to the councillors (synedroi) of the League and to Athens in the persons of her generals and hipparchs, and the synedroi together with Athenian generals and hipparchs swore oaths to Methymna. This has been seen as evidence of Methymna ‘converting a bilateral alliance into membership in the League’.Footnote 23 However, if indeed this is evidence of Methymna joining the League, it means that Methymna established a new treaty at that moment.Footnote 24 It is these new treaties that were mentioned in the Aristoteles Decree.Footnote 25
The Aristoteles Decree was not, therefore, the League’s founding document. Nor was it the official list of League members: those who share this idea believe that this list was neglected beginning in 375 or 373 or the late 370s.Footnote 26 For example, the name of Alcetas of Epirus remained on the list after he died in 370.Footnote 27 Nor did the Athenians erase the name of Thebes, which had dropped its League’s membership after (if not before, as we shall see below) the battle of Leuctra (371)—as opposed to how they (allegedly) erased the name of Jason of Pherae after his assassination in 370.Footnote 28 Neither were the names of the cities that renounced their membership in the League erased from the Decree, which many have noticed without providing a convincing explanation.Footnote 29
The apparent neglect of the membership list in the Aristoteles Decree has received diverse interpretations. Some argue that the League stopped admitting new members and, thus, interpret later treaties concluded by Athens and the League with individual states as withholding actual League membership.Footnote 30 However, such attempts fail to define the status of those states. Others believe that, while the League kept admitting new members, the Athenians did not add them to the list in order not to be bound by the principles outlined in the Aristoteles Decree.Footnote 31 But why did, then, the Athenians keep the Aristoteles Decree that invited Greek states to join the League based on those very principles? Still, the fact remains that, although Athens made treaties with Corcyra, Acarnania and Cephallenia in 375, only the last two found a place in the Aristoteles Decree.Footnote 32 Nor does the Decree list the Epirotes, the Athamanes and the Chaones, whom Timotheus made League members in 375, according to Nepos.Footnote 33
This neglect is closely related to the fact that, as many have already noted, the number of allies listed in the Aristoteles Decree (‘about fifty-eight’, according to some)Footnote 34 did not correspond to the total number of the League’s members, as far as it can be surmised. The Aristoteles stele had enough free space to add many new members and, although we do not know the overall number of League members, which certainly changed over time, it was more than 58: describing the beginning of the League in the early 370s, Diodorus noted that ‘seventy cities eventually entered into alliance with the Athenians and participated on equal footing in the common synedrion’. And, speaking in 343, Aeschines claimed that the Athenians had lost 75 allies during and after the Social War, which was clearly far from all of them: if Isocrates’ Areopagiticus dates to (after) the end of the Social War, Athens had ‘numerous’ members of the League when that war was over.Footnote 35 The scepticism of Cargill, who brusquely rejected the information of Diodorus and Aeschines, is unconvincing, just as his idea (shared, as we have seen, by some) that Athens stopped admitting new League members later in the 370s. What should we do with evidence for League membership from much later times, such as when, for example, Chalcis expressly declined to join the League in 341 b.c.?Footnote 36
A better explanation of why we see no new members in the Aristoteles Decree from the latter half of the 370s might be that this Decree was not concerned with meticulously keeping and adjusting the list of the League’s members in the first place. There should have been archival records and a specific public display for that purpose. Whether the ‘common stele of the allies’ mentioned in the Athenian decree on the League’s membership of Corcyra, Acarnania and Cephallenia meant the Aristoteles Decree (which seems to be the majority opinion) or a separate document is unclear.Footnote 37 We also have a (restored) reference to the ‘stele with treaties of the allies’ in the text of Thebes’ treaty with Athens, dated to before the Aristoteles Decree.Footnote 38 Such evidence suggests that the Athenians kept a separate record of the League members and that, accordingly, the Aristoteles Decree was not supposed to accomplish this task.
2. ATHENS’ IMPERIALIST POLICIES AND THE STATUS OF ATHENIAN ALLIES
The nature and purpose of the Aristoteles Decree thus require a reconsideration. Mossé interpreted Athens’ pledges in the Aristoteles Decree as showing ‘clearly that the initiators of the second maritime confederation had no intention of merely reverting to the imperialism of the preceding century’, and Cargill claimed that the League members occupied a privileged ‘free and autonomous’ position.Footnote 39 In a sense they did, but this was only one part of the story. Although Diodorus says in general terms that, after Sphodrias’ raid, the Athenians voted to restore the land settled by Athens’ cleruchs to its former owners and passed a law that no Athenian should cultivate lands outside of Attica, the Aristoteles Decree limited such measures only to League members:
For those who make alliance with the Athenians and the allies, the people shall renounce whatever Athenian possessions there happen to be, whether private or public, in the territory of those who make the alliance […] From the archonship of Nausinicus, it shall not be permitted either privately or publicly to any of the Athenians to acquire either a house or land in the territory of the allies […] If anyone does buy or acquire or take as security […] the synedroi shall sell it and give one half to the man who exposed, while the other shall be the common property of the allies.Footnote 40
By imposing this limitation, the Decree endorsed Athens’ right to occupy the land of non-members, thus pressuring them to join the League. The difference between the text of the Decree and its interpretation by Diodorus not only reminds us of Diodorus’ frequent inaccuracies but also portrays the Decree as a tool of Athens’ imperialist policies.
The same conclusion follows from Athens’ declared aim to preserve the freedom and autonomy of member-states. It took the form of their individual membership (IG II2 43.19–21): each of them held one seat in the synedrion,Footnote 41 which resided in Athens, had equal rights with other members and enjoyed but one vote.Footnote 42 This equality formally aligned with the principles of the King’s Peace,Footnote 43 which comprised the ‘territorial clause’ (acknowledging the right of the Persian king to certain territories and, accordingly, to their cities) and the ‘autonomy clause’ (ensuring the political, legal and administrative independence of Greek cities). In reality, the requirement of individual membership effectively undermined military alliances in Greece, which was the purpose of the ‘autonomy clause’, as some have already noted.Footnote 44
According to Dreher, however, the list of the League members included three dynasts, two demes and two federations, which Dreher saw as ‘special cases’.Footnote 45 The League membership of Alcetas I of Epirus and, as argued by some, Jason of Pherae, whose name was allegedly erased after his assassination, can and should be questioned.Footnote 46 The membership of ‘the Chalcidians from Thrace’ and of ‘the Acarnanians’ led Cargill to conclude that ‘Athens did not enforce the King’s Peace by breaking up leagues’.Footnote 47 But this would go against Athens’ declared principles of individual participation and autonomy.Footnote 48 Of Cargill’s two examples, the [Χαλκι]δῆς ἀπὸ [Θρᾴκης] appears to have been one specific entity, similar to Διε̑ς ἀπὸ Θρᾴκης, which is mentioned below,Footnote 49 whereas ‘the Acarnanians’ simply meant that they all joined the League one by one. If only some of the constituent parts became members, the Decree listed them individually together with their affiliation, such as, for example, Κεφαλληνῶν Πρῶννοι, as noted by Cargill himself, or Κείων Ἰουλιῆται Καρθαιε̑ς Κορήσιοι, or Ζακυνθίων ὁ δῆμος ὁ ἐν τῷ Νήλλῳ.Footnote 50 In short, the surviving list of League members in the Aristoteles Decree offers no indication that Athens reneged on the principle of individual membership or on her desire to break down local alliances. Federations and rulers could certainly be Athens’ allies, as were Amyntas III of Macedonia, Dionysius of Syracuse and Cersobleptes, king of Thrace, none of whom was a League member. The more important the potentate, the more unthinkable that he would have accepted Athenian hegemony by joining the Athenian League, noted Griffith, who saw Amyntas III, Dionysius and Jason as Athens’ allies without League membership.Footnote 51 Athens’ allies either had bilateral treaties with Athens and the League or were League members.Footnote 52
As the prostatês of the King’s Peace, the Spartans combined its ‘autonomy clause’ with keeping their military alliance. The Athenians advanced a similar claim now: the Aristoteles Decree guaranteed safety and independence to each current and future member of the Athenian alliance, breaking local hegemonies down to individual member-states: for example, Cean cities joined the League on an individual basis and, it appears, at different times,Footnote 53 and the same was true of Euboean cities, with Carystus, Eretria and Chalcis joining the League separately in 378–377,Footnote 54 and Histiaea becoming a member only later (in 375?), after Chabrias ‘laid waste’ her territory (and those of other Euboean communities that offered resistance) and left a garrison on her acropolis.Footnote 55 Having been reduced to individual participation, members of the League acknowledged the hegemony of Athens, meaning that Athens displayed her imperialism by usurping military and political leadership, having the final say regarding the League’s membership, representing members of the League internationally, and acting on their behalf.Footnote 56
The corresponding evidence suggests that the Aristoteles Decree was not a technical document but a piece of Athenian public propaganda that functioned in multiple ways. Since only League members were free from Athenian intervention, the Decree both incentivized the Greeks to join the League by threatening and attacking those who declined the invitation (such as Histiaea and, evidently, some other Euboean communities) and also reflected Athens’ policy of demolishing the military alliances of League members by enforcing individual participation and participation of non-members by using the autonomy clause. More specifically, the Decree ordered three Athenian ambassadors to be sent to Thebes, ‘who are to persuade the Thebans of whatever good thing they can’.Footnote 57 Some interpreted this phrase to mean that the Athenian envoys were dispatched to Thebes because, according to Buckler, ‘Theban obligations and responsibilities to the common council had [not] been spelled out in [the treaty between Athens and Thebes, known as] IG ii2 40’.Footnote 58 The Aristoteles Decree, however, included both the clause that the Athenian ambassadors ‘are to persuade the Thebans of whatever good thing they can’ (which sounded like acting in the interests of all Greeks) and the appeal that the Greeks join the League on the same terms as the Chians, the Thebans and ‘other allies’. The latter clause (IG II2 43.23–5) leaves no doubts that the provisions of Athens’ treaty with Thebes were clear enough and that Thebes had the same status as other League members.
Since Thebes occupied a place on the synedrion when the Aristoteles Decree was published, why did Athens need to dispatch her ambassadors? Athens’ intent ‘to persuade the Thebans of whatever good thing they can’ reflected the resurgence of Thebes’ Boeotian Federation: once the Spartan garrison left Thebes in the winter of 379/8, the Thebans proceeded to rebuild their alliance.Footnote 59 The Thebans’ request that Athens mount a naval expedition around the Peloponnese in 375 to divert the Spartans from another invasion of Boeotia further strained the relationship between Athens and Thebes: the Thebans not only failed to compensate Athens’ expenses but used that situation to further expand the Boeotian Federation and increase their military strength. According to a pseudo-Demosthenic speech, in 373, Athens both paid for Theban crews and, judging by a reference to the Theban admiral as ‘Boeotian’, effectively recognized the Boeotian Federation.Footnote 60 Thebes’ mounting military might and her growing control over Boeotia made Cargill, Jehne, Dreher, and Rhodes and Osborne, among others, surprised to see a Theban presiding over the synedrion of the Second League in a fragmented inscription comprising the last lines of an Athenian decree and the opening part of a decree of the League (the only known such specimen) about the affairs in Paros, which thus documented Thebes’ membership in the League still in 372.Footnote 61
One is even more surprised to see Thebes among League members in 372 when one remembers that the previous year the Thebans demolished Plataea and expelled its citizens and those of Thespiae from Boeotia (Diod. Sic. 15.46.4–6). It is for these reasons, says Xenophon (Hell. 6.3.1–2), that the Athenians decided to accept the Sparta Peace of 371 and invited Thebes to join in. The Athenians hoped to break down the Boeotian Federation with the help of the autonomy clause, just like it had happened in 386 and 375. As the Thebans claimed the right to swear on behalf of all the Boeotians at the King’s Peace of 386, Agesilaus dissolved the Boeotian Federation with the help of the autonomy clause that required Boeotian cities to join the Peace on an individual basis.Footnote 62 This is precisely what Agesilaus intended to do at the Sparta Peace of 371, which similarly required the Greeks to swear individual oaths, but with a very different outcome this time.Footnote 63 The general understanding has been that the Thebans combined League membership with their Boeotian hegemony or left the League (or forsook its membership) after reconstituting the Boeotian Federation.Footnote 64 The fact that the Athenians resigned to the use of the autonomy clause against the Thebans suggests that Thebes ceased to be a League member at some time between the above-mentioned presidency of a Theban over the synedrion in 372 and the Sparta Peace which was arranged shortly before the battle of Leuctra on 6 July 371.
In this context, the Aristoteles Decree appears to have been an Athenian tool to reinforce the principles of autonomy (for all Greeks) and individual participation (for League members) against the Thebans in an attempt to subvert the nascent re-edition of their Federation.Footnote 65 Nor did Athens allow the Thebans to join the League as ‘Boeotians’. At the level of individual cities, if the Thebans established their control over Histiaea in 377–376, the Athenians quickly turned it into a League member.Footnote 66 It appears that, as a piece of Athenian public propaganda, the Aristoteles Decree strove to destroy not only the Spartan domination but also the rising Theban hegemony.Footnote 67 Athens’ public claim to act for the freedom of the Greeks—against Sparta and (implicitly) against Thebes—explains why the Decree was displayed near the Stoa of Zeus Eleutherios,Footnote 68 which was built during Athens’ war against Sparta in the name of Greek freedom half a century earlier, while the cult of Zeus Eleutherios emerged in Athens in connection with the defeat of the Persian attempted encroachment on Greek freedom. Its location in the Agora made it accessible to anyone.
CONCLUSION
Although the Athenians could have developed plans to rebuild their military alliance earlier in the fourth century, their bilateral agreements with individual Greek city-states in the later 380s cannot be counted as proof of the League’s foundation. Regardless of whether they had such separate agreements with Athens (and the League), aspiring members had to make new treaties before taking their place on the League’s council. Judging by the available evidence, the League’s foundation occurred between the liberation of the Cadmea in the winter of 379/8 and Agesilaus’ invasion of Boeotia in the spring (early summer?) of 378. Far from being its founding document, the Aristoteles Decree publicly reasserted the fundamentals of the King’s Peace as the guiding principles of Athens’ military alliance. By pledging to protect League members’ safety and privileges—such as defence against attack, freedom and autonomy, self-government under any constitution desired, no collection of phoros, no imposition of Athenian garrisons and governors, and prohibition of Athenian property ownership in the territories of all member statesFootnote 69 —the Aristoteles Decree untied Athens’ hands against non-member states, incentivizing them to join the League.Footnote 70 Reinforcing the League’s individual membership, the Decree legitimized Athens’ protection of the Greeks not only from Sparta, which was the League’s declared purpose, but also from its own members, such as Thebes.
