Cotys, a name common to several kings of Thrace. The most important of them, a cruel and drunken tyrant, who began to reign in 382 B.C., was involved with the Athenians in a dispute for the possession of the Thracian Chersonese. In this he was assisted by the Athenian Iphicrates, to whom he had given his daughter in marriage. On the revolt of Ariobarzanes from Persia, Cotys opposed him and his ally, the Athenians. In 358 he was murdered by the sons of a man whom he had wronged.
