It is not possible here to follow the fortunes of the Crusaders. Several unauthorised expeditions, which bore witness to the popular enthusiasm, made their way through Southern Germany; but the disorderly crowds which composed them perished either at the hands of the inhabitants of the Eastern Empire, whom they treated as schismatics, or among the Turks in Asia Minor. The real expedition passed partly by land, partly by sea from the Italian ports to Constantinople, whence the Crusaders set out across Asia Minor. Nicæa was taken in June, 1097; the Sultan of Roum was overthrown in battle at Dorylæum in July; Antioch detained the Crusaders from October, 1097, to June, 1098; and it was only in July, 1099, that after a siege of forty days Jerusalem was captured from the Saracens of Egypt, who had recently recovered it from the Turks. [Sidenote: Its effect on the quarrel.] But whatever may have been Urban's success in his own land of France and elsewhere, in Germany, at any rate, his efforts to turn the current against the Emperor had entirely failed. Of German lands Lorraine alone sent warriors to the First Crusade. The movement did not penetrate to the east of the Rhine, and the number of Germans who helped to swell the multitude of crusaders who marched through Southern Germany was inappreciable. At the same time the settlement of the questions at issue between Papacy and Empire were indefinitely postponed; for it would have been treason to the crusading cause to press the papal claims against Henry at this moment. It was Henry's turn to experience some good fortune. The proclamation of the Truce of God under his auspices, the manifest interest of the German ecclesiastics, and his own policy of favouring the rising cities combined to strengthen his position. Thus in 1098 he was able to obtain from the German nobles the deposition of his rebellious son Conrad and the election of his younger son Henry as King, who was made to promise that during his father's lifetime he would not act politically against him. Then in 1099 Pope Urban died, and was followed in 1100 by the anti-Pope Clement III, and in 1101 by Conrad. All the personal causes of disunion were being removed. Moreover, the success of the crusading policy made it impossible that Henry or Germany should stand apart from it altogether. Although Jerusalem was the capital of a Christian kingdom and other principalities centred round Tripoli, Antioch, and the more distant Edessa, powerful Mohammedan Princes lay close beside them at Damascus, Aleppo, and Mossul, as well as to the south in Egypt. There was need of constant reinforcement, for the fighting was continual. Under these inducements Germany began to contribute crusaders to the cause. Duke Welf of Bavaria led an army eastwards in 1101. In 1103 Henry's efforts in favour of peace culminated in the proclamation at the Diet of Mainz of the first imperial land peace sworn between King and nobles, which
