Armenia becomes a Roman client

The Third Mithridatic War (73–63 BCE), 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 east of the Mediterranean and large parts of Asia (Asia Minor, Greater Armenia, Northern Mesopotamia and the Levant) into the war. The conflict ended in defeat for Mithridates, ending the Pontic Kingdom, ending the Seleucid Empire (by then a rump state), and also resulting in the Kingdom of Armenia becoming an allied client state of Rome.
