1911 Encyclopædia Britannica/Maximinus, Galerius Valerius
MAXIMINUS [Maximin], GALERIUS VALERIUS, Roman emperor from A.D. 308 to 314, was originally an Illyrian shepherd named Daia. He rose to high distinction after he had joined the army, and in 305 he was raised by his uncle, Galerius, to the rank of Caesar, with the government of Syria and Egypt. In 308, after the elevation of Licinius, he insisted on receiving the title of Augustus; on the death of Galerius, in 311, he succeeded to the supreme command of the provinces of Asia, and when Licinius and Constantine began to make common cause with one another Maximinus entered into a secret alliance with Maxentius. He came to an .open rupture with Licinius in 313, sustained a crushing defeat in the neighbourhood of Heraclea Pontica on the 50th of April, and lied, first to Nicomedia and afterwards to Tarsus, where he died in August following. His death was variously ascribed “ to despair, to poison, and to the divine justice.” Maximinus has a bad name in Christian annals, as of the toleration edict of Galerius, but it is probable that he has been judged too harshly.
