Diaeus

Diaeus of Megalopolis (, Diaios; died 146 BC) was the last strategos of the Achaian League in ancient Greece before the League was disbanded by the Romans. He served as the League's general from 150 to 149 BC and from 148 BC until his death.

==Dispute with the Lacedaemonians== Diaios was probably a son of Diophanes of Megalopolis, who had been a successful general of the Achaian League in 192/91 BC and who was himself the son of another Diaios. A member of the Arkadian aristocracy in the Achaian confederation, which comprised by then the entire Peloponnese, the younger Diaios was elected strategos of the Achaian League in 150 BC, succeeding Menalkidas of Sparta. Menalkidas had been charged by Kallikrates of Leontion with a capital offence, but saved himself by gaining the support of Diaios, whom he bribed with three talents. Diaios was generally blamed for this and, trying to divert public attention away from his own conduct, he sought a quarrel with Lakedaimon.
