There can be little doubt that Diocletian's reforms helped to prolong the existence of the empire. In one respect, however, they must be pronounced a failure. They did not end the disputes about the succession. Only two years after the abdication of Diocletian there were six rival pretenders for the title of _Augustus_. Their dreary struggles continued, until at length two emperors were left--Constantine in the West, Licinius in the East. After a few years of joint rule another civil war made Constantine supreme. The Roman world again had a single master. REIGN OF CONSTANTINE Constantine was an able general and a wise statesman. Two events of lasting importance have made his reign memorable. It was Constantine who recognized Christianity as one of the religions of the empire and thus paved the way for the triumph of that faith over the ancient paganism. His work in this connection will be discussed presently. It was Constantine, also, who established a new capital for the Roman world at Byzantium [6] on the Bosporus. He christened it "New Rome," but it soon took the emperor's name as Constantinople, the "City of Constantine." [7] FOUNDATION OF CONSTANTINOPLE Several good reasons could be urged for the removal of the world's metropolis from the Tiber to the Bosporus. The Roman Empire was ceasing to be one empire. Constantine wanted a great city for the eastern half to balance Rome in the western half. Again, Constantinople, far more than Rome, was the military center of the empire. Rome lay too far from the vulnerable frontiers; Constantinople occupied a position about equidistant from the Germans on the lower Danube and the Persians on the Euphrates. Finally, Constantine believed that Christianity, which he wished to become the prevailing religion, would encounter less opposition and criticism in his new city than at Rome, with its pagan atmosphere and traditions. Constantinople was to be not simply a new seat of government but also distinctively a Christian capital. Such it remained for more than eleven centuries. [8] AFTER CONSTANTINE, 337-395 A.D. After the death of Constantine the Roman world again entered on a period of disorder. The inroads of the Germans across the Danube and the Rhine threatened the European provinces of the empire with dissolution. The outlook in the Asiatic provinces, overrun by the Persians, was no less gloomy. Meanwhile the eastern and western halves of the empire tended more and more to grow apart. The separation between the two had become well marked by the close of the fourth century. After the death of the emperor Theodosius (395 A.D.) there came to be in fact, if not in name, a Roman Empire in the East and a Roman Empire in the West. POLITICAL SITUATION IN 395 A.D.
