Peloponnesian League


an alliance of the ancient Greek city-states of the Peloponnesus, with the exception of Argos and part of Achaea.

Established and headed by Sparta, the Peloponnesian League existed from the second half of the sixth century B.C. until the mid-fourth century B.C. It took form gradually as a result of a series of agreements between Sparta and the other city-states. Sparta strove for hegemony in the Hellenic world and hoped that its allies’ would assist in suppressing the uprisings of the Helots; the other city-states sought military support from Sparta.

The Peloponnesian League consistently supported oligarchic factions in the ancient Greek city-states. After Sparta’s victory in the Peloponnesian War (431–404 B.C.), it became a pan-Hellenic organization that installed oligarchic governments everywhere. The Peloponnesian League broke up after Sparta’s defeat in the war against Thebes (362 B.C.). An attempt to restore it in the 330’s failed.
