(b Dalmatia, 22 Dec AD ?244; reg AD 284–305; d ?3 Dec AD 311). Roman emperor and patron. In order to strengthen Imperial control at a time of extreme danger to the Roman world, Diocletian created the Tetrarchy in AD 293, a four-man system under which two Caesars were appointed: one served under Diocletian, the Augustus in the East, the other under Maximian, the Augustus in the West. The whole was held together only by the personality and authority of Diocletian himself, so that by the time of his death the Empire was once again beset by civil wars; his division of the Empire, however, and many of his administrative reforms lasted for much longer.
