MARCVS AVRELIVS VALERIVS MAXIMIANVS was born about 250 in Pannonia.  He was appointed Caesar by Diocletian in late 285, and co-Augustus by him in April, 286.  Maximian effectively ruled the west, while Diocletian ruled in the east.  He was finally forced by Diocletian to abdicate when Diocletian did (May, 305), but when his son Maxentius declared himself Augustus in October, 306, Maximian came out of retirement.  He was again forced to retire by the Council of Carnuntum in 308, but he rebelled against his son-in-law Constantine I and either committed suicide or was murdered at Marseilles in 310.
