Lycurgus (Greek: Λυκοῦργος Lykurgos; fl. 219–217 BC) was a king of Sparta, who reigned from 219 BC until his death shortly before 211 BC. Of obscure background and possibly of non-royal descent, Lycurgus led Sparta in the Social War against Macedon with varying success, and underwent multiple exiles during his checkered reign. He also effectively abolished the traditional Spartan diarchy by dethroning his fellow king Agesipolis III and ruling Sparta as its sole monarch.
