The Peloponnesian War was fought in the Eastern Mediterranean between the Athenian-led Delian League and the Spartan-led Peloponnesian League from 431 to 404 BC for hegemony over Ancient Greece. Initially inconclusive, the war turned decisively after the Persian Empire intervened in support of Sparta in 413 BC, allowing the Spartan coalition to defeat Athens and begin a period of Spartan hegemony over Greece.
