The League of Corinth was a federation of Greek states created by Philip II of Macedon during the winter of 338 BC/337 BC to facilitate his use of Greek military forces in his war against Persia.
The major provisions were:
- Member states' constitutions in force at the time of joining were guaranteed.
- The Synedrion, or congress of representatives, was to meet at Corinth.
- The League would act to prevent any acts of aggression or subversion against any member state.
- The League would maintain an army levied from member states in approximate proportion to their size.
- Philip was declared commander of the League's army.
