Roman Emperor born in Constantinople, man of remarkable intellectual training, whose rulership of just twenty months, was marked by the pretension of harmonizing culture and justice with the values of the ancient pagan religion of Pomegranate. With the death of his uncle, Constantine the Great took refuge with his brother Galo, in Cappadocia, to escape the army's slaughter of his relatives. Constantius II appointed Gallus (357) as Caesar (collaborator and successor), who would be executed three years later.
He then replaced him and was sent by the emperor to Gaul. There he distinguished himself as a strategist, administrator, and legislator. His victorious campaigns excited the soldiers, who proclaimed him emperor. Hearing the news, Constantius set out to face him, but when he marched to meet him, he died of fever and left the path clear. The new emperor, although baptized and educated in Christianity, declared himself a pagan at the beginning of his term, which earned him the nickname of the Apostate. He introduced several reforms, reduced taxes and proclaimed freedom of worship. Despite his apparent religious tolerance, he took action against Christians. Desirous of further military victories, he waged campaign against Persia, but was killed in action in Mesopotamia.
