Alliance established at Corinth in 337 BC.
It comprised the ancient Greek states except Sparta , and was led by Philip II of Macedonia. Delegates, elected in proportion to their state's military power, decided federal policies. The league declared war on Persia, but under Alexander the Great it contributed little to the war effort. Its major act was to condemn the Thebans to slavery and distribute their lands among other states following revolts in 336 and 335. It was disbanded after Alexander's death (323).
