The Arabian rulers had for their own interest protected the Christian pilgrims to the Holy Sepulchre. But even under the rule of the Fatimide dynasty, early in the 10th century, the oppression of pilgrims began. Khalif Hakim, in order that he might blot out the disgrace of being born of a Christian mother, committed ruthless cruelties upon resident Christians as well as upon the pilgrims, and prohibited under severe penalties all meetings for Christian worship. Under the barbarous Seljuk dynasty, which held sway in Palestine from about A.D. 1070, the oppression reached its height. The West became all the more concerned about this, since during the 10th century the idea that the end of the world was approaching had given a new impulse to pilgrimage to the Holy Land. Pope Sylvester II. had in A.D. 999 _ex persona devastatæ Hierosolymæ_ summoned Christendom to help in this emergency. Gregory VII. seized anew upon the idea of wresting the Holy Land from the infidels. He had even resolved himself to lead a Christian army, but the outbreak of contentions with Henry IV. hindered the execution of this plan. Meanwhile complaints by returning pilgrims of intolerable ill-usage increased. An urgent appeal from the Byzantine Emperor Alexius Comnenus gave the spark that lit the combustible material that had been gathered throughout the West. The imperial ambassadors accompanied Pope Urban II. to the Council of Clermont in A.D. 1095, where the pope himself, in a spirited speech, called for a holy war under the standard of the cross. The shout was raised as from one mouth, “It is God’s will.” On that very day thousands enlisted, with Adhemar, bishop of Puy, papal legate, at their head, and had the red cross marked on their right shoulders. The bishops returning home preached the crusade as they went, and in a few weeks a glowing enthusiasm had spread throughout France down to the provinces of the Rhine. Then began a movement which, soon extending over all the West, like a second migration of nations, lasted for two centuries. The crusades cost Europe between five and six millions of men, and yet in the end that which had been striven after was not attained. Its consequences, however, to Europe itself were all the more important. In all departments of life, ecclesiastical and political, moral and intellectual, civil and industrial, new views, needs, developments, and tendencies were introduced. Mediæval culture now reached the highest point of its attainment, and its failure to transcend the past opened the way for the conditions of modern society. And while on the other hand they afforded new and extravagantly abundant nourishment for clerical and popular superstition, in all directions, but specially in giving opportunity to roguish traffic in relics (§ 104, 8; 115, 9), on the other hand they had no small share in producing religious indifference and frivolous free-thinking (§ 96, 19), as well as the terribly dangerous
