And just as if the success of these diabolical schemes was not a sufficient triumph, fortune at this moment gave the Pope a chance of superseding the Emperor in the eyes of all Europe, by inaugurating a great popular movement of which under different circumstances the Emperor would have been the natural leader. In 1085 the Eastern Emperor Alexius had appealed to Henry against the Normans, but now Henry was a negligible quantity--excommunicated, crowned Emperor by an anti-pope, not likely to undertake a distant expedition. In 1095, therefore, when Alexius needed aid against the Seljuk Turks, it was to the Pope that he sent his envoys, who appeared at the Synod of Piacenza. Those late converts to Mohammedanism had established their kingdom of Roum over the greater part of Asia Minor with its capital at the venerable city of Nicæa, and had captured Jerusalem, which thus passed out of the hands of the tolerant Caliphs of Cairo into those of the most fanatical section of Mohammedans. Pilgrims returning from Jerusalem spread through Europe tales of the harsh treatment to which they were subjected. Then in 1087 a new tribe of Saracens, the Almoravides, crossed from Africa to Spain and inflicted a severe defeat upon a Christian army. It seemed almost as if a combined movement of the Mohammedan world had begun for the final extinction of Christendom. If Gregory had been free he would have wished to promote the reunion of the Churches by sending help to the Eastern Empire; so that it was no novel idea that was suggested to the assembled magnates at Piacenza. Urban II no doubt saw the opportunity offered for asserting the leadership of the western world. Alexius' envoys were heard with sympathy; but Urban felt the need of appeal to a larger public, and summoned a great Council to Clermont-Ferrand in Auvergne, where he would be among his own countrymen. Here in November, 1095, he delivered before a vast concourse of persons assembled in the open air an impassioned appeal on behalf of the suffering Christians of the east. The result answered his utmost expectation, and the cry of the assembled multitude, "God wills it," was the ratification of the papal leadership. All methods were taken to stir the feelings of the west. The vast ecclesiastical organisation was used in order to transmit invitations to possible crusaders; the penitential system of the Church was brought to bear on those already conscious of a sinful life; popular preachers, such as Peter the Hermit, were employed to rouse the interest of the masses; the Pope himself spent the succeeding months in a tour through Southern France; and arrangements were made for the start of the first expedition from the Italian ports at the end of the summer of 1096, under the leadership of a legate appointed by the Pope.
