The Battle of Tricamarum took place on December 15, 533 between the armies of the Vandals, commanded by King Gelimer, and his brother Tzazon, and the eastern Roman Empire (later referred to as the Byzantine Empire), under the command of General Belisarius. It followed Gelimer's defeat at the Battle of Ad Decimum, and eliminated the power of the Vandals for good, completing the "Reconquest" of North Africa under the Emperor Justinian I.
