When Byzantium, at the beginning of the thirteenth century, fell into the hands of the Latins, the empire still possessed great means of defence, and yet twenty thousand Crusaders achieved the conquest of it; which places the valour of the Franks much above that of the Turks. This would perhaps be the best place to examine what was the influence of the crusades over the destiny of the empire of the East. In the first expedition of the Latins, Asia Minor was delivered from the Turks, who were already masters of Nice, and threatened Constantinople; but the Crusaders sold the services they had rendered at too high a price: on the one part, violence, on the other, perfidy, disturbed the harmony that ought to have subsisted between the Greeks and the Latins. At length the taking of Constantinople by the Franks was a mortal blow to the empire of Byzantium. Amidst the war, schism became enlarged by hatred; and schism, in its turn, doubled the reciprocal hatred. This division favoured the progress of the Turks, and opened the gates of Constantinople to them.

What is most unfortunate in the conquest of the Ottomans is, that they preserved nothing, not even the name of Byzantium. The barbarians who overthrew the empire of the West, adopted the religion and manners of the conquered nations; which, by degrees, caused the traces of invasion and conquest to disappear. The Turks, on the contrary, were resolved to make the Koran triumph wherever they carried their arms. As soon as they were masters of Constantinople, the altars of Christ were overturned, and everything changed with religion. The city of Constantine became more widely than ever separated from Christendom; and as it was for the infidels the gate of the West, Christian Europe, which during nearly three centuries had sent its fleets and its armies into Asia, had reason at last to tremble for itself. From that period crusades took a new character, and were nothing but defensive wars.
