tion upon all who should be turned aside from the voyage to Jerusalem. But notwithstanding the fulminations of the Church, the expedition never reached Palestine. The siege of Zara was speedily undertaken. After a long and brave defence, the city surrendered at discretion, and the Crusaders were free, if they had so chosen it, to use their swords against the Saracens. But the ambition of the chiefs had been directed, by unforeseen circumstances, elsewhere.
After the death of Manuel Comnenus, the Greek empire had fallen a prey to intestine divisions. His son Alexius II. had succeeded him, but was murdered after a short reign by his uncle Andronicus, who seized upon the throne. His reign also was but of short duration. Isaac Angelus, a member of the same family, took up arms against the usurper, and having defeated and captured him in a pitched battle, had him put to death. He also mounted the throne only to be cast down from it. His brother Alexius deposed him, and to incapacitate him from reigning, put out his eyes, and shut him up in a dungeon. Neither was Alexius III. allowed to remain in peaceable possession of the throne; the son of the unhappy Isaac, whose name also was Alexius, fled from Constantinople, and hearing that the Crusaders had undertaken the siege of Zara, made them the most magnificent offers if they would afterwards aid him in deposing his uncle. His offers were, that if by their means he was re-established in his father's dominions, he would place the Greek Church under the authority of the Pope of Rome, lend the whole force of the Greek empire to the conquest of Palestine, and distribute two hundred thousand marks of silver among the crusading army. The offer was accepted, with a proviso on the part of some of the leaders, that they should be free to abandon the design, if it met with the disapproval of the pope. But this was not to be feared. The submission of the schismatic Greeks to the See of Rome was a greater bribe to the Pontiff than the utter annihilation of the Saracen power in Palestine would have been.
The Crusaders were soon in movement for the imperial city. Their operations were skilfully and courageously directed, and spread such dismay as to paralyse the efforts of the usurper to retain possession of his throne. After a vain resistance, he abandoned the city to its fate, and fled no one knew whither. The aged and blind Isaac was taken from his dungeon by his subjects, and placed upon the throne ere the Crusaders were apprised of the flight of his rival. His son Alexius IV. was afterwards associated with him in the sovereignty.
But the conditions of the treaty gave offence to the Grecian people, whose prelates refused to place themselves under the dominion of the See of Rome. Alexius at first endeavoured to persuade his subjects to admission, and prayed the Crusaders to remain in Con-
