 After a month and half Xerxes II was murdered by his brother Secydianus or Sogdianus (the form of the name is uncertain).His illegitimate brother, Ochus, satrap of Hyrcania, rebelled against Sogdianus, and after a short fight killed him, and suppressed by treachery the attempt of his own brother Arsites to imitate his example.Ochus adopted the name Darius (Greek sources often call him Darius "Nothos", "Bastard").
