350 BC
Idrieus, the second son of Hecatomnus, succeeds to the throne of Caria on the death of Artemisia II, the widow of his elder brother Mausolus. Shortly after he becomes ruler, at the request of the Persian king, Artaxerxes III, Idrieus equips a fleet of 40 triremes and an army of 8,000 mercenary troops and despatches them against Cyprus, under the command of the Athenian general Phocion.
