Constantine I, also known as Constantine the Great, was Roman emperor from AD 306 to 337. He was the first emperor to convert to Christianity. Born in Naissus, Dacia Mediterranea, he was the son of Flavius Constantius, a Roman army officer of Illyrian origin who had been one of the four rulers of the Tetrarchy. His mother, Helena, was a Greek woman of low birth and a Christian. Later canonized as a saint, she is traditionally attributed with the conversion of her son. Constantine served with distinction under the Roman emperors Diocletian and Galerius. He began his career by campaigning in the eastern provinces before being recalled in the west to fight alongside his father in the province of Britannia. After his father's death in 306, Constantine was acclaimed as imperator by his army at Eboracum. He eventually emerged victorious in the civil wars against emperors Maxentius and Licinius to become the sole ruler of the Roman Empire by 324.

The Religious policies of Constantine the Great have been called "ambiguous and elusive." Born in 273 during the Crisis of the Third Century, Constantine the Great was thirty at the time of the Great Persecution. He saw his father become Augustus of the West and then shortly die. Constantine spent his life in the military warring with much of his extended family, and converted to Christianity sometime around 40 years of age. His religious policies, formed from these experiences, comprised increasing toleration of Christianity, limited regulations against Roman polytheism with toleration, participation in resolving religious disputes such as schism with the Donatists, and the calling of councils including the Council of Nicaea concerning Arianism. John Kaye characterizes the conversion of Constantine, and the Council of Nicea that Constantine called, as two of the most important things to ever happen to the Christian church.
