He was possibly a son of his predecessor, Nicocles, and a grandson of Evagoras I. He followed a pro-Persian course, for which he was deposed ca. 351 BC by a popular revolt led by his nephew Pnytagoras, who succeeded him as king.
Evagoras fled to the Persian court, where Artaxerxes III gave him the government of the Phoenician city of Sidon, following the defeat of the rebellion of Tennes. His administration of Sidon was so bad that after three years, in 346 BC, he was chased out of the city by the populace, who called upon a descendant of the ancient royal line, Abdashtart II, to replace him. Evagoras fled back to Cyprus, where he was arrested and executed.
