After his coronation, Baldwin wrote to the pope, to announce to him the extraordinary victories by which it had pleased God to crown the zeal of the soldiers of the cross. The new emperor, who assumed the title of knight of the Holy See, recalled to the mind of the sovereign pontiff the perfidies and the long revolt of the Greeks. “We have brought under your laws,” said he, “that city, which, in hatred for the Holy See, would scarcely hear the name of the prince of the apostles, and did not afford a single church to him who received from the Lord the supremacy over all churches.” Baldwin, in his letter, invited the vicar of Jesus Christ to imitate the example of his predecessors, John, Agapetus, and Leo, who visited in person the Church of Byzantium. To complete the justification of the pilgrims who had made themselves masters of the Greek empire, the emperor invoked the testimony of all the Christians of the East. “When we entered into this capital,” added he, “many inhabitants of the Holy Land, who were there, expressed greater joy than any others, and asserted aloud that we had rendered God a more agreeable service than if we had retaken Jerusalem.” The marquis of Montferrat at the same time addressed a letter to the sovereign pontiff, in which he protested his humble obedience to all the decisions of the Holy See. “As for me,” said the king of Thessalonica, “who only took up the cross for the expiation of my sins, and not to obtain an opportunity of sinning with more license under the pretext of religion, I submit myself blindly to your will. If you judge that my presence in Romania may be useful, I will die there, contending against your enemies and those of Christ: if you think, on the contrary, I ought to abandon these rich countries, pay no regard to the wealth or dignities I possess there, I am ready to return to the West; for I am not willing to do anything that will draw upon me the anger of the sovereign judge.” The doge of Venice, who till that time had braved with so much haughtiness the threats and thunders of the Church, acknowledged the sovereign authority of the pope, and joined his protestations with those of Baldwin and Boniface. To disarm the anger of Innocent, they represented to him that the conquest of Constantinople had prepared the deliverance of Jerusalem, and boasted of the wealth of a country which the Crusaders had at length brought under the laws of the Holy See. In all their letters to the pope or the faithful of the West, the conquerors of Byzantium spoke of the Greek empire as of a new land of promise, which awaited the servants of God and the soldiers of Christ.
