Cyrus II
Cyrus (Old Persian Kurush): Persian prince, born in 424 BC, probably in Susa, as the second son of king Darius II. In 408, Cyrus was appointed satrap of Lydia. When his older brother, Artaxerxes II Mnemon, became king in 404, Cyrus decided to revolt. He recruited fourteen thousand Greek mercenaries and marched to the east. At Cunaxa, near Babylon, his army was victorious (in 403 BC), but he himself fell. His mercenaries had to fight back through Armenia; six thousand survived. He is also known as "Cyrus the Younger."

Our main source on the expedition is the eyewitness account written by the Athenian commander Xenophon, the Anabasis.
