Definition of arcadian league in English English dictionary
Confederation of ancient Greek city-states of Arcadia. Arcadian towns had been forced to ally with Sparta by 550 BC, and most Arcadians remained faithful to Sparta during the Peloponnesian War (431-404 BC). In an effort to contain Sparta, Epaminondas of Thebes founded the city-state of Megalopolis in 371-368 BC as the seat of the Arcadian League. The League united the Arcadians for a few decades until internal discord crippled their confederation
