October 28, 312 – Battle of the Milvian Bridge

The conversion of Roman Emperor Constantine to Christianity is a major milestone in Christian history. While historians still argue if Constantine’s conversion was legitimate, his acceptance of Christ traditionally took place on October 28, 312 when he fought a battle against his pagan co-emperor, Maxentius, at the Milvian Bridge just outside Rome. Constantine claims to have seen a sign of Jesus Christ in the sky which he credited for winning the battle that day.
