deavor, with him, to regain the power they had laid aside, he replied: " Were you but to come to Salona and see the vegetables which I raise in my garden with my own hands, you would no longer talk to me of empire."
Reign of Constantine the Great (A.D. 306–337) ; the Empire becomes Christian.—Galerius and Constantius had reigned together only one year, when the latter died at York, in Britain; and his soldiers, disregarding the rule of succession as determined by the system of Diocletian, proclaimed his son Constantine emperor. Six competitors for the throne arose in different quarters. For eighteen years Constantine fought to gain supremacy. At the end of that time every rival was crushed, and he was the sole ruler of the Roman world.
Constantine was the first Christian emperor. He was converted to the new religion—such is the legend—by seeing in the heavens, during one of his campaigns against his rivals, a luminous cross with this inscription: "With this sign you will conquer." He made the cross the royal standard; and the Roman legions now for the first time marched beneath the emblem of Christianity.
By a decree issued from Milan A.D. 313, Christianity was made in effect the state religion; but all other forms of worship were tolerated. With the view of harmonizing the different sects that had sprung up among the Christians, and to settle the controversy between the Arians and the Athanasians respecting the nature of Christ,—the former denied his equality with God the Father,—Constantine called the first Œcumenical, or General Council of the Church, at Nicæa, a town of Asia Minor, A.D. 325. Arianism was denounced, and a formula of Christian faith adopted, which is known as the Nicene Creed.
After the recognition of Christianity, the most important act of Constantine was the selection of Byzantium, on the Bosporus, as the new capital of the empire. One reason which led the emperor to choose this site in preference to Rome was the ungracious conduct towards him of the inhabitants of the latter city, because he had abandoned the worship of the old national deities.
