Third Mithridatic War
The Second Mithridatic War began when Rome tried to annex Bithynia as a province. In the Third Mithridatic War, first Lucius Licinius Lucullus and then Pompey the Great were sent against Mithridates. Mithridates was finally defeated by Pompey in the night-time Battle of the Lycus. After defeating Mithridates, Pompey invaded Caucacus, subjugated the Kingdom of Iberia and established Roman control over Colchis.
