God's War: A New History of the Crusades

The use of the symbol of the cross at Clermont signalled a pivotal concern for Jerusalem. Urban himself certainly presided over cross-giving at Tours (March 1096) and probably Le Mans (February), and it is likely that he or his agents distributed crosses wherever he preached. Ceremonies conducted by Urban’s deputies, by local clergy or unofficially proliferated. Apparently at one such occasion at Rouen a riot ensued. Using relics of the cross as a prop to encourage participation, as Urban had done at Marmoutier, became fashionable. It could backfire. An English annalist described how, during the preaching of the Jerusalem expedition, a French abbot constructed his own cross, passing it off as having been made by God: as a punishment, he was afflicted with cancer.³⁰ It is an indication of the independent role assumed by Peter the Hermit, possibly retrospectively, that he carried as a preaching aid a letter from heaven rather than a relic of the cross which, within a year of Clermont, had swept all other symbols aside. Giving the cross was simple and non-discriminatory. Unlike the granting of the symbols of pilgrimage, which assumed a contractual imposition of a penance by a priest, in the first flush of the new ritual, presenting crosses was not a monopoly of those in holy orders. In June 1096, at Amalfi in Apulia, as a carefully staged demonstration of piety and power, the Italian-Norman lord Bohemund of Taranto provided crosses for his men. Although never becoming the exclusive preserve of holy warriors, wearing the cross was immediately distinctive. At Amalfi, Bohemund had been particularly struck by the crosses worn by passing crusaders. Those in the army to Jerusalem themselves referred to recruits who had not yet fulfilled their vows as being ‘signed with the holy cross’ while in 1098 they wrote to Urban himself that he had ‘ordered us to follow Christ carrying our crosses’.³¹ For others these badges carried more sinister implications. One of the words employed by Hebrew chroniclers to describe the perpetrators of the Rhineland pogroms of 1096 translates as ‘those bearing insignia’, signs of an obsession with the Crucifixion and vengeance on those allegedly responsible who still denied Christ’s divinity.³² For Christian warrior and persecuted Jew, the cross was definitive.

Urban’s message delivered at Clermont and repeated in sermons and letters over the next three years, emerged clearly: penitential warfare to rescue Jerusalem and the eastern churches from Islam; the liberation of the eastern church after centuries of bondage with the implication of the restoration of fraternal unity with, as one eyewitness at Clermont later had it, ‘blood-brothers’;³³ the prospect of the remission of all sins, as Urban clearly stated in December 1095, for those warriors who had taken the cross in sign of their acceptance of their duty to follow Christ; the obligation to revenge the loss of Christ’s Holy Land as a debt of honour; the realization of papal leadership of Christendom; the transformation of a sinful military aristocracy into a godly order. It is not entirely clear how far this was from what Alexius I had envisaged when he despatched yet another embassy to the pope early in 1095, but it is certain that Urban’s scheme owed more to his own rather than the Greek’s designs. Not the least remarkable feature of the inception of the Jerusalem expedition was that the casus belli was the sole invention of the aggressors, almost entirely unimagined by their target. In the west, Urban’s penitential war marked a significant step on the path towards incorporating all Christendom into a militia Dei against unbelievers and sinners.
