Greece

• King Agesipolis I leads a Spartan army against Argos. Since no Argive army challenges him, he plunders the countryside for a time, and then, after receiving several unfavorable omens, returns to Sparta.
• The Athenian general, Thrasybulus, sails to Lesbos, where, with the support of the Mytileneans, he defeats the Spartan forces on the island and wins over a number of cities. While still on Lesbos, however, Thrasybulus is killed by raiders from the city of Aspendus where his financial exactions have made him unpopular.
• Concerned about the revival of Athenian imperialist ambitions, the Persian King Artaxerxes II and King Agesilaus II of Sparta enter into an alliance. Sparta also seeks and gains the support of Dionysius I of Syracuse.
