Flavius Valerius Constantine was born AD 272. He accompanied his father the western Emperor Constantius I to Britain in a hard fought campaign against the Picts in northern Britain. At Eboracum (York) on the 25th July AD 306 Constantius died from ill health and the soldiers proclaimed Constantine as their leader. He at first took the junior rank of Caesar to avoid conflict with the other rulers of the Roman tetrarchy, and he accepted the joint title of Augustus in 307, becoming sole ruler in 324 after deposing the eastern Roman emperor Licinius.
