The leaning of the Athenian deputies had been adverse rather than favorable to Thebes throughout the congress. They were disinclined, from their sympathies with the Platæans, to advocate the presidential claims of Thebes, though on the whole it was the political interest of Athens that the Bœotian federation should be maintained, as a bulwark to herself against Sparta. Yet the relations of Athens with Thebes, after the congress as before it, were still those of friendship, nominal rather than sincere. It was only with Sparta, and her allies, that Thebes was at war, without a single ally attached to her. On the whole, Kallistratus and his colleagues had managed the interests of Athens in this congress with great prudence and success. They had disengaged her from the alliance with Thebes, which had been dictated seven years before by common fear and dislike of Sparta, but which had no longer any adequate motive to countervail the cost of continuing the war; at the same time, the disengagement had been accomplished without bad faith. The gains of Athens, during the last seven years of war, had been considerable. She had acquired a great naval power, and a body of maritime confederates; while her enemies the Spartans had lost their naval power in the like proportion. Athens was now the ascendent leader of maritime and insular Greece,—while Sparta still continued to be the leading power on land, but only on land; and a tacit partnership was now established between the two, each recognizing the other in their respective halves of the Hellenic hegemony.[364] Moreover, Athens had the prudence to draw her stake, and quit the game, when at the maximum of her acquisitions, without taking the risk of future contingencies.

On both sides, the system of compulsory and indefeasable confederacies was renounced; a renunciation which had already been once sworn to, sixteen years before, at the peace of Antalkidas, but treacherously perverted by Sparta in the execution. Under this new engagement, the allies of Sparta or Athens ceased to constitute an organized permanent body, voting by its majority, passing resolutions permanently binding upon dissentients, arming the chief state with more or less power of enforcement against all, and forbidding voluntary secessions of individual members. They became a mere uncemented aggregate of individuals, each acting for himself; taking counsel together as long as they chose, and coöperating so far as all were in harmony; but no one being bound by any decision of the others, nor recognizing any right in the others to compel him even to performance of what he had specially promised, if it became irksome. By such change, therefore, both Athens and Sparta were losers in power; yet the latter to a much greater extent than the former, inasmuch as her reach of power over her allies had been more comprehensive and stringent.
