The Turkish conquest of Islam and its counterblast, the Crusades, were an immense misfortune for the world. They permanently worsened the relations between East and West. In the year A.D. 1000 Christian-Moslem relations were fairly good, and showed every prospect of becoming better. The hatreds engendered by Islam's first irruption were dying away. The frontiers of Islam and Christendom had become apparently fixed, and neither side showed much desire to encroach upon the other. The only serious debatable ground was Spain, where Moslem and Christian were continually at hand-grips; but, after all, Spain was mutually regarded as a frontier episode. Between Islam and Christendom, as a whole, intercourse was becoming steadily more friendly and more frequent. This friendly intercourse, if continued, might ultimately have produced momentous results for human progress. The Moslem world was at that time still well ahead of western Europe in knowledge and culture, but Saracenic civilization was ossifying, whereas the Christian West, despite its ignorance, rudeness, and barbarism, was bursting with lusty life and patently aspiring to better things. Had the nascent amity of East and West in the eleventh century continued to develop, both would have greatly profited. In the West the influence of Saracenic culture, containing, as it did, the ancient learning of Greece and Rome, might have awakened our Renaissance much earlier, while in the East the influence of the mediaeval West, with its abounding vigour, might have saved Moslem civilization from the creeping paralysis which was overtaking it. But it was not to be. In Islam the refined, easygoing Saracen gave place to the bigoted, brutal Turk. Islam became once more aggressive--not, as in its early days, for an ideal, but for sheer blood-lust, plunder, and destruction. Henceforth it was war to the knife between the only possible civilization and the most brutal and hopeless barbarism. Furthermore, this war was destined to last for centuries. The Crusades were merely Western counter-attacks against a Turkish assault on Christendom which continued for six hundred years and was definitely broken only under the walls of Vienna in 1683. Naturally, from these centuries of unrelenting strife furious hatreds and fanaticisms were engendered which still envenom the relations of Islam and Christendom. The atrocities of Mustapha Kemal's Turkish "Nationalists" and the atrocities of the Greek troops in Asia Minor, of which we read in our morning papers, are in no small degree a "carrying on" of the mutual atrocities of Turks and Crusaders in Palestine eight hundred years ago.
