minor princes of Asia, who were suffering under the Ottoman tyranny, to come and protect them. Tamerlane was flattered by the request, and having brought a great army into Phrygia, he was there met by Bajazet, the Ottoman emperor, who readily gave battle, but was defeated and made prisoner (1402). Tamerlane made Samarcand the capital of his empire, and there received the homage of all the princes of the East. Illiterate himself, he was solicitous for the cultivation of literature and science in his dominions; and Samarcand became for a while the seat of learning, politeness, and the arts, but was destined to relapse after a short period into its ancient barbarism. The Turks, after the death of Tamerlane, resumed their purpose of destroying the empire of the East. The honor, or disgrace, as it may be thought, of effecting this, fell to the lot of Mohammed II, commonly surnamed the Great. At the early age of twenty-one, Mohammed projected this conquest. His countrymen had already passed into Europe; they had possessed themselves of the city of Adrianople, and indeed had left nothing of all the empire of the East to the Greeks but the city of Constantinople itself. The preparations made for defense were not such as became the descendants of Romans, and the powers of Europe now looked upon the East with the most supine indifference. The Turks assailed the city both on the land side and on that of the sea; and battering down its walls with their cannon, entered sword in hand, and massacred all who opposed them (1453). Mohammed, like many other ambitious conquerors, showed himself unwilling to destroy unnecessarily. The imperial edifices were preserved, and the churches were converted into mosques; the exercise of their religion was freely allowed to the Christians, and this privilege they have never been deprived of. Constantine (for that was the name of the last, as well as the first emperor of the East) was slain in battle. From the time that it was founded by Constantine the Great, the city had subsisted 1123 years. Mohammed liberally patronized the arts and sciences. He was himself not only a politician, but a scholar, and he invited both artists and men of letters to his capital from the kingdoms of Europe. But the taking of Constantinople had an effect contrary to his wishes: it dispersed the learned Greeks, or Greeks who were called learned, all over Europe; and this, among other things, may be looked upon as a help to the great revival of letters which the fifteenth century witnessed. The taking of Constantinople was followed by the conquest of Greece and Epirus; and Italy might probably have met with a similar fate, but for the fleet of the Venetians, who opposed the arms of Mohammed with considerable success, and even attacked him in Geece; but the contending powers soon after put an end to hostilities by a treaty. By this time Europe was trembling at Mohammed's success, and was afraid, not without reason, that he might pursue his conquests westward. It was relieved from fear by his death, which took place in 1481. His descendants have continued to our own day to occupy one of the finest countries in Europe; and it was only in the present age that Greece was liberated from their dominion.
RISE OF CIVIL FREEDOM AND SOCIAL IMPROVEMENT.
Civil freedom, as we have seen, dawned first in the great commercial cities of Italy, whence it spread to Germany, Flanders, and Britain.
