In 1095, facing invasion on all sides, the Byzantine ruler Alexios I sent ambassadors to plead for help from the pope and an opportunity for a reconciliation between the two churches. Pope Urban II was a supporter of church reform, and that put him at odds with German emperors like Henry IV, who insisted on his own right to appoint bishops, even the bishop of Rome. To avoid being in Italy when Henry was, Urban traveled throughout western Europe, preaching repentance from sins and obedience to the church. He answered the Byzantine emperor’s call for aid, but in a way Alexios was probably not expecting.
Urban II presented his idea of religious war in response to the Byzantine request for aid at a council in Clermont, France, in 1095. While the council was ostensibly about reform, Urban also issued a call for Christians from all walks of life to undertake an “armed pilgrimage” to liberate the Christian Holy Land (the lands of the eastern Mediterranean associated with the life of Jesus and the biblical prophets, including Jerusalem) from “Turkic” control. Urban’s goal at this point was to free the Holy Land from non-Christian rulers in defense of the Christians living there; it was not a blanket endorsement of violence against Muslims. These limitations were later eased, however, as the popes discovered the power of calling repeated crusades to promote the reforming goals of the church and to compete with political rivals in Europe, like the German emperors.
While the Byzantine emperor wanted aid for his realm, Urban instead sent the crusaders to Jerusalem. Urban’s directive to “liberate Jerusalem” and support the Christians in the Middle East was clever. Few Europeans knew or cared about the problems of Constantinople, but the church’s reforming and educational efforts had made the life of Jesus in Jerusalem and the early Christian community there a focal point in people’s imaginations. Catholics prized relics of saints as a means of fostering their devotion and bringing them closer to the divine, and Jerusalem was in effect an enormous relic, a gateway to heaven itself. Preachers like Peter the Hermit whipped up crowds of men and women with the idea of a glorious pilgrimage to the most sacred of cities (Figure 13.17). The call to crusade stirred western Christians into action, soldiers and knights as well as poor peasants and zealots.
Urban also hoped to restore unity to the church by offering help to the Byzantine Empire. What we know of his speeches shows how he tied this effort together with his reform program. Freeing Jerusalem from “the wicked” would mirror the rallying cries to free the church from aristocratic control. After all, the reason Urban called for the crusade while in France was that he had to contend with a rival pope, supported by the German emperor, who had occupied Rome since before Urban became pope. Urban was also likely concerned about guarding the frontiers of Christianity, which compelled him to insist that Spanish Christians should not go on this pilgrimage because they were needed at home in the persistent struggle against Islam in the Iberian Peninsula.
Finally, Urban’s ability to inspire the people of Europe signaled the influence he wielded over Christians at large. The popes had no armies, and they often had to depend on the unreliable aristocracy for protection when disagreements over church policy resulted in armed conflict with the princes of Europe. If they were to maintain their control over the church in contests with kings and emperors, it would be useful to see what happened when a pope rallied common Christians to a religious cause as a test of faith. Thousands were willing to stitch a cross onto their clothes, a sign that they were on this special pilgrimage and the source of the word “crusade.”
