THE DECLINE OF THE OTTOMAN EMPIRE.

While the great monarchies of Western Europe were struggling for pre?minence, and were developing resources greater than had ever before been exhibited since the fall of the Roman empire, that great power which had alarmed and astonished Christendom in the sixteenth and seventeenth centuries, Saracenic Empire. began to show the signs of weakness and decay. Nothing, in the history of society, is more marvellous than the rise of Mohammedan kingdoms. The victories of the Saracens and Turks were rapid and complete; and in the tenth century, they were the most successful warriors on the globe, and threatened to subvert the world. They had planted the standard of the Prophet on the walls of Eastern capitals, and had extended their conquests to India on the east, and to Spain on the west. Powerful Mohammedan states had arisen in Asia, Africa, and Europe, and the Crusaders alone arrested the progress of these triumphant armies. The enthusiasm which the doctrines of Mohammed had kindled, cannot easily be explained; but it was fresh, impetuous, and self-sacrificing. Successive armies of Mohammedan invaders overwhelmed the ancient realms of civilization, and reduced the people whom they conquered and converted to a despotic yoke. But success enervated the victorious conquerors of the East, the empire of the Caliphs was broken up, and great changes took place even in those lands where the doctrines of the Koran prevailed. Mohammed perpetuated a religion, but not an empire. Different Saracenic chieftains revolted from the "Father of the Faithful," and established separate kingdoms, or viceroyalties, nearly independent of the acknowledged successors of Mohammed. The Saracenic empire was early dismembered, and the sultans of Egypt, Spain, and Syria contested for pre?minence.

But a new power arose on the ruins of the Saracen empire, and became the enthusiastic defenders of the religion of Islam. The Rise of the Turks. Turks were an obscure tribe of barbarians when Bagdad was the seat of a powerful monarchy. Their origin has been traced to the wilds of Scythia; but they early deserted their native forests in search of more fruitful regions. When Apulia and Sicily were subdued by the Norman pirates, a swarm of these Scythian shepherds settled in Armenia, probably in the ninth century, and, by their valor and simplicity, soon became a powerful tribe. Not long after they were settled in their new abode, the Sultan of Persia invoked their aid to assist him in his wars against the Caliph of Bagdad, his great rival. The Turks complied with his request, and their arms were successful. The sultan then refused to part with such useful auxiliaries, and moreover, fearing their strength, designed to employ them in his wars against the Hindoos, and to shut them up in the centre of his dominions. The Turkmans rebelled, withdrew into a mountainous part of the country, became robbers, and devastated the adjacent countries. The band of robbers gradually swelled into a powerful army, gained a great victory over the troops of the Sultan Mohammed, and placed their chieftain upon the Persian throne, (1038.) According to Gibbon, the new monarch was chosen by lot, and Seljuk had the fortune to win the prize of conquest, and became the founder of the dynasty of the Shepherd kings. During the reign of his grandson Togrul, the ancient Persian princes were expelled, and the Turks embraced the religion of the conquered. In 1055, the Turkish sultan delivered the Caliph of Bagdad from the arms of the Caliph of Egypt, who disputed with him the title of Commander of the Faithful. For this service he was magnificently rewarded by the grateful successor of the Prophet, who, at that time, banqueted in his palace at Bagdad—a venerable phantom of power. The victorious sultan was publicly commissioned as lieutenant of the caliph, and he was virtually seated on the throne of the Abbassides. Shortly after, the Turkish conqueror invaded the falling empire of the Greeks, and its Asiatic provinces were irretrievably lost. In the latter part of the eleventh century, the Turkish power was established in Asia Minor, and Jerusalem itself had fallen into the hands of the sultan. He exacted two pieces of gold from the Christian pilgrim, and treated him, moreover, with greater cruelty than the Saracens had ever exercised. The extortion and oppression of the Turkish masters of the Sacred City led to the Crusades and the final possession of Western Asia by the followers of the Prophet. The Turkish power constantly increased with the decline of the Saracenic and Greek empires, but the Seljukian dynasty, like that of Abbassides at Bagdad, at last run out, and Othman, a soldier of fortune, became sultan of the Turks. He is regarded as the founder of the Ottoman empire, and under his reign, from 1299 to 1326, the Moslems made rapid strides in the progress of aggrandizement.

Orkham, his son, instituted the force of the Janizaries, completed the Turkish Conquerors. conquest of Bithynia, and laid the foundation of Turkish power in Europe. Under his successor, Amurath I., Adrianople became the capital of the Ottoman empire, and the rival of Constantinople. Bajazet succeeded Amurath, and his conquests extended from the Euphrates to the Danube. In 1396, he defeated, at Nicopolis, a confederate army of one hundred thousand Christians; and, in the intoxication of victory, declared that he would feed his horse with a bushel of oats on the altar of St. Peter, at Rome. Had it not been for the victories of Tamerlane, Constantinople, which contained within its walls the feeble fragments of a great empire, would also have fallen into his hands. He was unsuccessful in his war with the great conqueror of Asia, and was defeated at the battle of Angora, (1402,) and taken captive, and carried to Samarcand, by Tamerlane, in an iron cage.

The great Bajazet died in captivity, and Mohammed I. succeeded to his throne. He restored, on a firmer basis, the fabric of the Ottoman monarchy, and devoted himself to the arts of peace. His successor, Amurath II., continued hostilities with the Greeks, and laid siege to Constantinople. But this magnificent city, the last monument of Roman greatness, resisted the Turkish arms only for a while. In 1453, it fell before an irresistible force of three hundred thousand men, supported by a fleet of three hundred sail. The Emperor Constantine succeeded in maintaining a siege of fifty-three days; and the religion and empire of the Christians were trodden to the dust by the Moslem conquerors. The city was sacked, the people were enslaved, and the Church of St. Sophia was despoiled of the oblations of ages, and converted into a Mohammedan mosque. One hundred and twenty thousand manuscripts perished in the sack of Constantinople, and the palaces and treasure of the Greeks were transferred to semi-barbarians.

From that time, the Byzantine capital became the seat of the Ottoman empire; and, for more than two centuries, Turkish armies excited the fears and disturbed the peace of the world. Progress of the Turks. They gradually subdued and annexed Macedonia, the Peloponnesus, Epirus, Bulgaria, Servia, Bosnia, Armenia, Cyprus, Syria, Egypt, India, Tunis, Algiers, Media, Mesopotamia, and a part of Hungary, to the dominions of the sultan.
