A century after the death of Mahomet, the Moslems had extended their religion and their arms from India to the Atlantic Ocean; they had subdued and converted, by the power of the sword, Persia and Egypt, and all the north of Africa, from the mouth of the Nile to the extreme western boundary of that vast continent; they overran Spain, invaded France, and turning their footsteps towards Italy they entered the kingdoms of Naples and Genoa, threatened Rome, and subjected the island of Sicily to the laws and the religion of their Prophet. But at the very period when they were about to plant the Koran in the very heart of Europe, and were advancing with rapid strides to universal dominion, intestine dissensions broke out amongst them which undermined their power, and Europe was released from the dread and danger of Saracen dominion. In the tenth century of the Christian era, however, the ferocious and barbarous Turcomans appeared as the patrons of Mahommedanism, and the propagators of the Koran. These were wild pastoral tribes of shepherds and hunters, who descended from the frozen plains to the north of the Caspian, conquered Persia, embraced the religion and the law of Mahomet, and became united under the standard of the Prophet into one great and powerful nation. They overran the greater part of the Asiatic continent, destroyed the churches of the Christians and the temples of the Pagans, and appeared (A. D. 1084) in warlike array on the Asiatic shore of the Hellespont in front of Constantinople. The terrified emperor Alexius sent urgent letters to the Pope and the christian princes of Europe, exhorting them to assist him and their common Christianity in the perilous crisis. The preachings of Peter the hermit, and the exhortations of the Pope, forthwith aroused Christendom; Europe was armed and precipitated upon Asia; the Turkish power was broken; the Christian provinces of the Greek empire of Constantinople were recovered from the grasp of the infidels; and the Latin kingdom of Jerusalem was reared upon the ruins of the Turkish empire of sultan Soliman. The monastic and military order of the Temple was then called into existence for the purpose of checking the power of the infidels, and fighting the battles of Christendom in the plains of Asia. “Suggested by fanaticism,” as Gibbon observes, but guided by an intelligent and far reaching policy, it became the firmest bulwark of Christianity in the East, and mainly contributed to preserve Europe from Turkish desolation, and probably from Turkish conquest.
