Peace of Antalcidas
When the war with Sparta stagnated in 375 BC, a willingness to make peace developed in Sparta and Athens. The Spartans could no longer hope for a victory and the Athenians had achieved their goals: the freedom of Thebes from Spartan control and the recognition of the sea league as compatible with the terms of the Peace of Antalcidas. Diodorus reports an embassy of the Great King came to secure a renewal of the peace, since the Persians needed peace in Greece in order to free the mercenaries up for a war they wanted to undertake in Egypt. The Greek states accepted the agreement and the Common Peace was renewed.
