Galerius Valerius Maximianus, was born near Sardica in Dacia, and was the son of a shepherd. He rose from the ranks to the highest commands in the army, and was appointed Caesar by Diocletian, along with Constantius Chlorus, in 292. Upon the abdication of Diocletian and Maximian in 305, Galerius became Emperor. In 307, he made an unsuccessful attempt to recover Italy, which had owned the authority of the usurper Maxentius. He died in 311 of disease.
