Pharnaces I King of Kings of the Kingdom of Pontus from ~185 BC to ~170 BC.
Pharnaces I was the fifth king of Pontus, and the son of King Mithradates III and his wife Laodice, whom he succeeded on the throne. He ruled c. 190 BC – c. 155 BC, but the precise year of his ascension is not known.

In 183 BC he attacked Sinope, after which the Rhodians sent an ambassador to Rome with a complaint but nothing came of it. Soon after he attacked Eumenes II of Pergamon and Ariarathes IV of Cappadocia. Fighting continued until 179 BC, after which Pharnaces I was forced to concede defeat.

How long he continued to reign after this we know not; but it appears that he was still on the throne in 170 BC, while he was certainly dead in 154 BC, when his brother Mithradates IV is mentioned as King.
