ABSTRACT
During the epochal reign of Diocletian (284-305), Constantius would be delegated a share of imperial power, and be elevated to the rank of Caesar in the western half of the Roman Empire. He would play a central role in the new order established by Diocletian. Constantine would reach manhood in these years, and, as the son of the western Caesar, would gain valuable knowledge about the imperial government and give valorous service in the Roman military under the tutelage of the eastern emperors.
