The ill-humour with which the news of the battle of Leuctra was received at Athens seems to have arisen merely out of the old jealousy and animosity with which the Athenians had been used to regard their northern neighbours, and which revived as soon as the affairs of Thebes became prosperous. For in the event itself, considered with respect to their own interests, they could have seen nothing to deplore. And they proceeded without delay to take advantage of the shock which it had given to the influence of Sparta. It seems to have been the prevailing opinion throughout Greece, and not least at Sparta itself, that the Spartan power had suffered a fatal blow; and Xenophon intimates that the Athenians were surprised to find that any of the Peloponnesian states still adhered to the ancient chief of their confederacy. They believed that the time had now come when Athens might step into the place of Sparta, as guardian of the Peace of Antalcidas, and might transfer all the advantages which her rival had reaped from that title to herself. They therefore assembled a congress in their own city, to which they invited deputies not only from their old allies, but from all the states of Greece which were willing to adopt the Peace of Antalcidas as the basis of their mutual relations. It seems to have been attended by many, if not by most members of the Peloponnesian confederacy; and the resolution to which it came in the oath by which each state was to ratify the compact was thus expressed: “I will abide by the treaty sent down by the king, and by the decrees of the Athenians and their allies, and if an attack be made on any of the states which take this oath, I will succour it with all my might.” So that Athens found herself able to obtain better security for the execution of the treaty, than had been given in the last congress held for the like purpose at Sparta, where none of the parties had been bound to enforce its observance by arms: and yet the engagement for mutual defence now involved those who entered into it in danger of a contest both with Sparta and Thebes. Elis would gladly have united herself to an association which would separate, and might protect her, from Sparta; but she would not resign her claims to the sovereignty of the Triphylian towns. The congress on the other hand determined that every town, small or great, should be alike independent, and commissioners were sent round to exact an oath to this effect from the magistrates of each state. It was taken, Xenophon says, by all but the Eleans. MANTINEA RESTORED
