Overview
Balakros, also Balacrus, the son of Nicanor, one of Alexander the Great's "Somatophylakes" (bodyguards), was appointed satrap of Cilicia after the Battle of Issus, 333 BC. He succeeded to the last Achaemenid satrap of Cilicia, Arsames.
Career
Balakros completed the conquest of Asia Minor together with Calas, satrap of Hellespontine Phrygia, and Antigonus, satrap of Phrygia.
It was probably this Balacrus who married Phila, the daughter of Antipater, and subsequently the wife of Craterus.
He was probably supervised by Menes from 331 BC, who held the position of Hyparch or Strategoi for the area from Babylon to the satrapies of Syria, Phoenicia, and Cilicia.
