For Christian anarchists the moment which epitomises the degeneration of Christianity is the conversion of Emperor Constantine after his victory at the Battle of the Milvian Bridge in 312. Following this event Christianity was legalized under the Edict of Milan in 313, hastening the Church's transformation from a humble bottom-up sect to an authoritarian top-down organization. Christian anarchists point out that this marked the beginning of the "Constantinian shift", in which Christianity gradually came to be identified with the will of the ruling elite, becoming the State church of the Roman Empire, and in some cases (such as the Crusades, Inquisition and Wars of Religion) a religious justification for violence.
