Constantine Wins the Battle of the Milvian Bridge
On October 28, 312, Roman emperor Constantine defeated his rival Maxentius at the Battle of the Milvian Bridge, just outside Rome. According to early Christian writers, Constantine had a vision before the battle, prompting him to fight under the sign of the cross. Maxentius’ forces were driven back toward the Tiber River, where the bridge collapsed and he drowned. Constantine’s victory paved the way for his sole rule of the Western Roman Empire and his later support for Christianity, including the Edict of Milan.
