His coins give his name as M., or more frequently as C., Flavius Valerius Constantinus. He was born at Naissus, now Nisch in Servia Nis, Serbia --Ed., the son of a Roman officer, Constantius, who later became Roman Emperor, and St. Helena, a woman of humble extraction but remarkable character and unusual ability. The dateof his birth is not certain, being given as early as 274 and as late as 288. After his father's elevation to the dignity of Caesar we find him at the court of Diocletian and later (305) fighting under Galerius on the Danube. When, on the resignation of his father, Constantius was made Augustus, the new Emperor of the West asked Galerius, the Eastern Emperor, to let Constantine, whom he had not seen for a long time, return to his father's court. This was reluctantly granted. Constantine joined his father, under whom he had just time to distinguish himself in Britain before death carried off Constantius (25 July, 306). Constantine was immediately proclaimed Caesar by his troops, and his title was acknowledged by Galerius somewhat hesitatingly. This event was the first break in Diocletian's scheme of a four-headed empire (tetrarchy) and was soon followed by the proclamation in Rome of Maxentius, the son of Maximian, a tyrant and profligate, as Caesar, October, 306.

During the wars between Maxentius and the Emperors Severus and Galerius, Constantine remained inactive in his provinces. The attempt which the old Emperors Diocletian and Maximian made, at Carmentum in 307, to restore order in the empire having failed, the promotion of Licinius to the position of Augustus, the assumption of the imperial title by Maximinus Daia, and Maxentius' claim to be sole emperor (April, 308), led to the proclamation of Constantine as Augustus. Constantine, having the most efficient army, was acknowledged as such by Galerius, who was fighting against Maximinus in the East, as well as by Licinius.
