Mithridatic dynasty

The Mithridatic dynasty, also known as the Pontic dynasty, was a hereditary dynasty of Persian origin, founded by Mithridates I Ktistes (Mithridates III of Cius) in 281 BC. The origins of the dynasty were located in the highest circles of the ruling Persian nobility in Cius. Mithridates III of Cius fled to Paphlagonia after the murder of his father and his predecessor Mithridates II of Cius, eventually proclaiming the Kingdom of Pontus, and adopting the epithet of "Ktistes" (literally, Builder). The dynasty reached its greatest extent under the rule of Mithridates VI, who is considered the greatest ruler of the Kingdom of Pontus. They were prominent enemies of the Roman Republic during the Mithridatic Wars during the reign of Mithridates VI until the late 60s BC. In 48 BC, the Roman client king of Crimea, Pharnaces II, attempted to press his claim on Pontus, but was decisively defeated by Julius Caesar at the Battle of Zela.
