Pleistoanax (reigned 459 BC – 409 BC) was an Agiad King of Sparta. He was most anxious for Peace during the Archidamian War, the first phase of the Peloponnesian War. He was exiled in 446 BC, charged by the Spartans with taking a bribe to withdraw from the plain of Eleusis in Attica after leading the Peloponnesian forces there. In 428 BC, he was recalled and restored in obedience to the Delphic oracle's advice. His enemies still blamed him for Spartan disasters, so Pleistoanax advocated peace to bring an end to the disasters.
