The Second Mithridatic War was one of three wars fought between Pontus and the Roman Republic. This war was fought between King Mithridates VI of Pontus and the Roman general Lucius Licinius Murena.

Mithridates' ambitious son-in-law, Tigranes the Great, king of Armenia, however, saw an opportunity for expansion in the constant civil strife to the south. In 83 BC, at the invitation of one of the factions in the interminable civil wars, he invaded Syria and soon established himself as ruler of Syria, putting the Seleucid Empire virtually at an end.
