Biography of Constantine the Great

Constantine the Great (Latin: Flavius Valerius Aurelius Constantinus Augustus;[2] Greek: Κωνσταντ᠖νΠς ὁ Μέγας; 27 February c. 272 AD[1] - 22 May 337 AD), also known as Constantine I or Saint Constantine,[3] was a Roman Emperor of Illyrian and Greek origin from 306 to 337 AD. He was the son of Flavius Valerius Constantius, a Roman Army officer, and his consort Helena. His father became Caesar, the deputy emperor in the west, in 293 AD. Constantine was sent east, where he rose through the ranks to become a military tribune under Emperors Diocletian and Galerius. In 305, Constantius raised himself to the rank of Augustus, senior western emperor, and Constantine was recalled west to campaign under his father in Britannia (Britain). Constantine was acclaimed as emperor by the army at Eboracum (modern-day York) after his father's death in 306 AD, and he emerged victorious in a series of civil wars against Emperors Maxentius and Licinius to become sole ruler of both west and east by 324 AD.
