The Third Mithridatic War, the last and longest of the three Mithridatic Wars, was fought between Mithridates VI of Pontus and the Roman Republic. Both sides were joined by a great number of allies, dragging the entire Eastern Mediterranean and large parts of Asia into the war. The conflict ended in defeat for Mithridates; it ended the Pontic Kingdom and the Seleucid Empire, and also resulted in the Kingdom of Armenia becoming an allied client state of Rome.
