So that the error which the emperor had committed, in soliciting Licinius to affix his signature to the Decree of Milan, was not only fully compensated by his consummate skill and artifice, but the Church prayed earth and Heaven for the destruction of Licinius. Licinius, irritated more and more by the wide-spread disaffection of his subjects, espoused the cause of Bassianus, who had married Anastasia, the sister of Constantine, and urged him into rebellion in order to gain larger power; and, Bassianus having been defeated and dethroned, Licinius refused to deliver up the partisans of the fallen Cæsar who had taken refuge in his dominions; and upon this pretext Constantine declared war against him; and in two battles, one at Cibalis in Pannonia, and the other upon the plains of Mardia in Thrace, he defeated Licinius, and so crippled him that he was compelled to make peace, with the loss of Pannonia, Dalmatia, Dacia, Macedonia, and Greece, which provinces were added to the dominions of Constantine, and extended his empire to the extremity of Peloponnesus, leaving Licinius Emperor of Thrace, Asia Minor, Syria, and Egypt. This war happened in the year 315, and the ambition of Constantine was temporarily sated, so that he then refrained from pushing to extremities the defeated but still powerful Licinius until he might have time and opportunity to alienate the affection and confidence of his subjects in Asia as thoroughly as he had done in Europe. And, besides this, he wanted time in order to subjugate the Goths whom Ulfilas had converted, subvert the Christian communities organized among them on the primitive foundation, and force them to adopt the ecclesiastical system which he had established at Rome, in order to make the Gothic nation an available factor in any future war in which he might engage. But in a few years afterward, having successfully waged war against the Goths, and having seen the influence of Licinius greatly impaired by the persecutions of the Church in Syria and Egypt which he had encouraged and, perhaps, instigated, as well as by that secret diplomacy of which Constantine was master, the Roman emperor deemed that the time had come to destroy Licinius, and restore the unity of the empire, and consolidate all power in his own hands, especially as the great age and unpopular vices of Licinius seemed to presage an easy victory. He accordingly (and without any pretext whatever on this occasion) declared war against the Illyrian emperor; and in the great battle of Adrianople, and in the siege of Byzantium, and in the decisive action of Chrysopolis, in all of which he engaged Licinius with inferior numbers, his vast military genius asserted itself, so that by continuous defeats he reduced the Emperor of the East to the necessity of making an unconditional surrender. Constantia, the wife of Licinius, was the sister of Constantine, and, at her request and entreaties, the conqueror temporarily spared the life of
