Bithynia et Pontus
Most of the western half of Pontus and the Greek cities of the coast, including Sinope, were annexed by Rome directly as part of the Roman province of Bithynia et Pontus. The interior and eastern coast remained an independent client kingdom. The Bosporan Kingdom also remained independent under Pharnaces II of Pontus as an ally and friend of Rome. Colchis was also made into a client kingdom. PharnacesII later made an attempt at reconquering Pontus. During the civil war of Caesar and Pompey, he invaded Asia Minor (48BC), taking Colchis, lesser Armenia, Pontus, and Cappadocia and defeating a Roman army at Nicopolis. Caesar responded swiftly and defeated him at Zela, where he uttered the famous phrase 'Veni, vidi, vici'. Pontic kings continued to rule the client Kingdom of Pontus, Colchis, and Cilicia until PolemonII was forced to abdicate the Pontic throne by Nero in 62CE.
