GALERIUS or GALERIUS VALERIUS MAXIMIANUS, a Roman emperor; born of humble parentage, near Sardica, Dacia. Entering the imperial army, he rose rapidly to the highest ranks. In 292 Diocletian conferred on him the title of Caesar, and gave him his daughter in marriage. In 296-297 he conducted a campaign against the Per sians, in which he decisively defeated their king, Narses. On the abdication of Diocletian (305) he and Constantius Chlorus became joint rulers of the Ro man empire, Galerius taking the E. half. When Constantius died in York (306) the troops in Britain and Gaul immedi ately transferred their allegiance to his son, Constantine (afterward Constantine the Great). Galerius, however, retained possession of the E. till his death. He died in A. D. 311.
