Constantine the Great [SEP] Introduction
Constantine the Great (; ; 27 February 22 May 337), also known as Constantine I, was a Roman emperor from AD 306 to 337. Born in Naissus, Dacia Mediterranea (now Niš, Serbia), he was the son of Flavius Constantius, an Illyrian army officer who became one of the four emperors of the Tetrarchy. His mother, Helena, was Greek and of low birth. Constantine served with distinction under emperors Diocletian and Galerius campaigning in the eastern provinces against barbarians and the Persians, before being recalled west in 305 to fight under his father in Britain. After his father's death in 306, Constantine was acclaimed as emperor by the army at Eboracum (York).
