Constantine the Great (r. 306–337 CE) was the first Roman emperor to convert to Christianity and one of the most influential rulers in late antiquity. He reunited the divided empire after winning a series of civil wars, most famously defeating Maxentius at the Battle of the Milvian Bridge in 312, where he claimed to have received a divine sign promising victory. As emperor, he issued the Edict of Milan (313), granting religious tolerance to Christians, and later convened the Council of Nicaea (325), which helped define core Christian doctrine. He founded Constantinople on the site of Byzantium in 330, creating a new imperial capital that would endure for over a thousand years. His reign marked the transition from the classical Roman world to the Christian Byzantine era.
