League of Corinth

In 337 BC, after his victory at Chaeronea, Philip II of Macedon summoned the Greek city-states to a congress at Corinth. There they formed an alliance known to historians as the League of Corinth. Every major Greek state joined except Sparta, which refused. The members swore to keep a common peace, not to overthrow each other's governments, and to provide soldiers for joint military action. A council of representatives from the member states was established, and Philip was named hegemon, or leader, of the alliance and commander of its forces. The League's declared purpose was a war of revenge against Persia, especially for the burning of Greek temples during the invasion of 480 BC, and to free the Greek cities of Asia Minor. In practice, the League was a way for Macedon to control Greece while allowing the cities to keep their local independence. Philip was assassinated in 336 BC before the war could begin. His son Alexander had himself confirmed as the League's leader and went on to lead its war against Persia.
