The Battle of Bar took place on October 7, 1042 between the army of Stefan Vojislav, the Serbian ruler of Duklja, and Byzantine forces led by Michaelus Anastasii. The battle was actually a sudden attack on the Byzantine camp in the mountain gorge, which ended in the utter defeat of the Byzantine forces and the deaths of 7 of their commanders (strategoi). Following the defeat and retreat of the Byzantines, Vojislav ensured a future for Duklja without imperial authority, and Duklja would soon emerge as the most significant Serb state.
