Constantine first distinguished himself in the service of Diocletian in the Egyptian and Persian wars; went afterward to Gaul and Britain, and in the Praetorium at York was proclaimed emperor by his dying father and by the Roman troops. His father before him held a favorable opinion of the Christians as peaceable and honorable citizens, and protected them in the West during the Diocletian persecution in the East. This respectful, tolerant regard descended to Constantine, and the good effects of it, compared with the evil results of the opposite course of his antagonist Galerius, could but encourage him to pursue it. He reasoned, as Eusebius reports from his own mouth, in the following manner: 'My father revered the Christian God, and uniformly prospered, while the emperors who worshipped the heathen gods, died a miserable death; therefore, that I may enjoy a happy life and reign, I will imitate the example of my father and join myself to the cause of the Christians, who are growing daily, while the heathen are diminishing.' This low utilitarian consideration weighed heavily in the mind of an ambitious captain, who looked forward to the highest seat of power within the gift of his age. Whether his mother, whom he always revered, and who made a pilgrimage to Jerusalem in her eightieth year (A. D. 325), planted the germ of the Christian faith in her son, as Theodoret supposes, or herself became a Christian through his influence, as Eusebius asserts, must remain undecided. According to the heathen Zosimus, whose statement is unquestionably false and malicious, an Egyptian, who came out of Spain (probably the bishop Hosius of Cordova, a native of Egypt, is intended), persuaded him, after the murder of Crispus (which did not occur before 326), that by converting to Christianity he might obtain forgiveness of his sins. The first public evidence of a positive leaning toward the Christian religion he gave in his contest with the pagan Maxentius, who had usurped the government of Italy and Africa, and is universally represented as a cruel, dissolute tyrant, hated by heathens and Christians alike. Called by the Roman people to their aid, Constantine marched from Gaul across the Alps with an army of ninety-eight thousand soldiers of every nationality, and defeated Maxentius in three battles; the last in October, 312, at the Milvian bridge, near Rome, where Maxentius found a disgraceful death in the waters of the Tiber.
