Page "337 BC" Paragraph 3

* At a Pan-Hellenic Conference in Corinth, Philip II of Macedon announces the formation of the League of Corinth to liberate the Greek cities of Asia Minor from Persian rule, ostensibly because the Persian King, Arses, refuses to make reparations to Philip for Artaxerxes III's aid to the city of Perinthus when it was resisting Philip.

All the Greek cities ( except Sparta ) and the Greek islands swear their support to the league and to recognise Philip as president of the League.

Philip establishes a council of representatives from all the Greek states, which is empowered to deliberate and decide on the actions to be taken.

However, the real power lies with Philip who is declared commander of the League's army.
