Tetricus I (271–274 CE) was the last emperor of the Gallic Empire, a breakaway Roman state encompassing Gaul, Britain, and parts of Hispania during the Crisis of the Third Century. A former governor of Aquitania, he succeeded Victorinus and ruled alongside his son, Tetricus II, whom he appointed Caesar. His reign was troubled by Germanic invasions and internal rebellions. In 274, he was defeated by the Roman emperor Aurelian at the Battle of Châlons, bringing the Gallic Empire to an end. Tetricus was spared and subsequently received a position in the Roman administration.
