Overview
Pharnaces II of Pontus (; about 97–47 BC) was the king of the Bosporan Kingdom and Kingdom of Pontus until his death. He was a monarch of Persian and Greek ancestry. He was the youngest child born to King Mithridates VI of Pontus from his first wife, his sister Queen Laodice. He was born and raised in the Kingdom of Pontus and was the namesake of his late double great grandfather Pharnaces I of Pontus. After his father was defeated by the Romans in the Third Mithridatic War (73–63 BC) and died in 63 BC, the Romans annexed the western part of Pontus, merged it with the former Kingdom of Bithynia and formed the Roman province of Bithynia and Pontus. The eastern part of Pontus remained under the rule of Pharnaces as a client kingdom until his death.
Rebellion against his father
Pharnaces II was raised as his father's successor and treated with distinction. However, little is known of his youth from ancient writers and find him first mentioned after Mithridates VI was defeated by the Roman general Pompey during the Third Mithridatic War. Cassius Dio and Florus wrote that Mithridates planned to attack Italy by crossing Scythia and the River Danube, according to the former, or through Thrace, Macedonia and the rest of Greece, according to the latter. Appian also wrote about a planned invasion of Italy, but did not mention any routes. The scale of the expedition put many of his soldiers off. Castor of Phanagoria and his city rebelled. Many of the castles he had occupied on the eastern shores of the Black sea also rebelled. This was followed by a rebellion by Pharnaces.
Appian wrote that Pharnaces conspired against his father. The conspirators were captured and tortured. However, Mithridates was persuaded to spare Pharnaces. The latter feared his father's anger and knew that Mithridates’ soldiers were not keen on the expedition. He went to Roman deserters who were encamped near Mithridates to highlight the dangers of the expedition and to encourage them to desert his father. He sent other people to do the same in other camps. In the morning there was an uprising. Mithridates fled and Pharnaces was proclaimed king by the troops. Mithridates sent messengers to ask his son for permission to withdraw safely. When they did not return, he tried to poison himself. However, it did not have an effect on him because he was used to taking small portions of poison as a protection against poisoners. Thus, he got an officer to kill him.
