Already in the course of the preliminary debates, Epaminondas had spoken out boldly against the ascendency of Sparta. While most of the deputies stood overawed by her dignity, represented by the energetic Agesilaus as spokesman,—he, like the Athenian Autoklês, and with strong sympathy from many of the deputies present, had proclaimed that nothing kept alive the war except her unjust pretensions, and that no peace could be durable unless such pretensions were put aside.[356] Accepting the conditions of peace as finally determined, he presented himself to swear to them in the name of the Bœotian federation. But Agesilaus, requiring that each of the Bœotian cities should take the oath for itself, appealed to those same principles of liberty which Epaminondas himself had just invoked, and asked him whether each of the Bœotian cities had not as good a title to autonomy as Thebes. Epaminondas might have replied by asking, why Sparta had just been permitted to take the oath for her allies as well as for herself. But he took a higher ground. He contended that the presidency of Bœotia was held by Thebes on as good a title as the sovereignty of Laconia by Sparta.[357] He would remind the assembly that when Bœotia was first conquered and settled by its present inhabitants, the other towns had all been planted out from Thebes as their chief and mother-city; that the federal union of all, administered by Bœotarchs chosen by and from all, with Thebes as president, was coeval with the first settlement of the country; that the separate autonomy of each was qualified by an established institution, devolving on the Bœotarchs and councils sitting at Thebes the management of the foreign relations of all jointly. All this had been already pleaded by the Theban orator fifty-six years earlier, before the five Spartan commissioners, assembled to determine the fate of the captives after the surrender of Platæa; when he required the condemnation of the Platæans as guilty of treason to the ancestral institutions of Bœotia;[358] and the Spartan commissioners had recognized the legitimacy of these institutions by a sweeping sentence of death against the transgressors. Moreover, at a time when the ascendency of Thebes over the Bœotian cities had been greatly impaired by her anti-Hellenic coöperation with the invading Persians, the Spartans themselves had assisted her with all their power to reëstablish it, as a countervailing force against Athens.[359] Epaminondas could show, that the presidency of Thebes over the Bœotian cities was the keystone of the federation; a right not only of immemorial antiquity, but pointedly recognized and strenuously vindicated by the Spartans themselves. He could show farther that it was as old, and as good, as their own right to govern the Laconian townships; which latter was acquired and held (as one of the best among their own warriors had boastfully proclaimed)[360] by nothing but Spartan valor and the sharpness of the Spartan sword.
