Greece Athens founds the town of Kos on the island of Kos in the Aegean Sea. Theban leader, Epaminondas, returns to the Peloponnesus for a third time, seeking to secure the allegiance of the states of Achaea. Although no army dares to challenge him in the field, the democratic governments he establishes there are short-lived, as pro-Spartan aristocrats soon return to the cities, reestablish the oligarchies, and bind their cities ever more closely to Sparta. Thebes makes peace with Sparta and then turns its attention on Athens, which is trying to revive its maritime empire and is interfering in Macedonian dynastic quarrels. Thebes captures the city of Oropus.
