By 47 BC, Asander had married
Dynamis, the daughter of Pharnaces II by a
Sarmatian wife, as his second wife. She was a granddaughter of King
Mithridates VI of Pontus by his first wife, his sister
Laodice. In 47 BC, Pharnaces II put Asander in charge of the Bosporan Kingdom while he went with an army to invade the eastern parts of
Anatolia. Following a successful campaign, Pharnaces advanced towards the western parts of Anatolia. However, he had to stop because Asander revolted against him. Asander hoped that by betraying his father-in-law he would win favour with the Romans and they could help him become the Bosporan King . Pharnaces defeated
Roman general
Gnaeus Domitius Calvinus but was then defeated by
Julius Caesar. After this defeat, Pharnaces fled to
Sinope with 1,000 cavalry. From Sinope Pharnaces sailed to the Cimmerian Bosporus (without his horses), intending to recover his kingdom from Asander. He captured Theodosia (
Feodosia) and
Panticapaeum. In response, Asander attacked him. Pharnaces was defeated and killed in the battle because he was short of horses and his men were not used to fighting on foot.
Strabo wrote that Asander took possession of the Bosporus. == Overthrow of Asander ==
