League of Corinth
The League of Corinth, also referred to as the Hellenic League (Greek: κοινὸν τῶν Ἑλλήνων, koinòn tõn Hellḗnōn; or simply οἱ Ἕλληνες, the Héllēnes), was a federation of Greek states created by Philip II of Macedon in 338–337 BC. The League was created in order to unify Greek military forces under Macedonian hegemony (leadership) in a pan-Hellenic expedition against the Persian Achaemenid Empire. King Philip was initially urged by Isocrates in 346 BC to unify Greece against the Persians.
