Artaxerxes II Mnemon (c. 436 - 358 BC) was king of Persia from 404 BC until his death. He defended his position against his brother Cyrus the Younger, who was defeated and killed at the Battle of Cunaxa in 401 BC, and against a revolt of the provincial governors, the Satraps (366 - 358). In 386 BC Artaxerxes II forced Greek poleis to come to terms and sign the treaty of 'universal peace' (Treaty of Antalcidas).
The country nevertheless declined under his rule.
