During the Crisis of the Third Century, the Roman Empire had suffered multiple difficulties: drought, famine, plagues, inflation, invading barbarians. Numerous Roman generals had fought over the rule of the empire, resulting in civil wars and the rule of the so-called barracks emperors who were chosen and often quickly replaced by the Roman army. Constantine’s opposition in the West was Maxentius and their armies met near the Milvian Bridge in Rome, a bridge across the northern outskirts on the Via Flaminia. Maxentius fell into the river (with his armor) and drowned. Constantine became the sole ruler in the West.The night before meeting at the Milvian Bridge, Constantine prayed for success in the coming battle. Either in a vision or a dream, he saw an image with the script "In Hoc Signo Vinces" ("In this sign, conquer"). Controversy still swirls around both the event and the image that he saw.
