Вифиния и Понт
The Kingdom of Pontus (, "Basileía toû Póntou") was a Hellenistic-era kingdom, centered in the historical region of Pontus and ruled by the Mithridatic dynasty of Persian origin, which may have been directly related to Darius the Great and the Achaemenid dynasty. The kingdom was proclaimed by Mithridates I in 281BC and lasted until its conquest by the Roman Republic in 63BC. The Kingdom of Pontus reached its largest extent under Mithridates VI the Great, who conquered Colchis, Cappadocia, Bithynia, the Greek colonies of the Tauric Chersonesos, and for a brief time the Roman province of Asia. After a long struggle with Rome in the Mithridatic Wars, Pontus was defeated. The western part of it was incorporated into the Roman Republic as the province Bithynia et Pontus; the eastern half survived as a client kingdom until 62 AD.
