Peloponnesian League


The Peloponnesian League (c. 550 BCE - c. 366 BCE) was a loose confederation of Greek city-states led by Sparta. The League was the oldest and longest-lasting political association in the ancient Greek world. For Sparta, the League gave it protection from uprisings within its own borders and eventually secured its dominance in the region and later, following victory in the Peloponnesian War in 404 BCE, the whole of Greece. Then, coming up against a rampant Thebes and their brilliant general Epaminondas, Sparta was defeated at the Battle of Leuctra in 371 BCE. Without its dominant leader the League dissolved shortly thereafter.
