This represents a laxity of toleration impossible in any other land at the period, yet the Spanish Jews were not wholly shielded from inroads of foreign fanaticism. Before the crusading spirit had been organized for the conquest of the Holy Land, ardent knights sometimes came to wage war with the Spanish Saracens, and their religious fervor was aggrieved by the freedom enjoyed by the Jews. About 1068, bands of these strangers treated them as they had been wont to do at home, slaying and plundering them without mercy. The Church of Spain was as yet uncontaminated by race hatred and the bishops interposed to save the victims. For this they were warmly praised by Alexander II, who denounced the crusaders as acting either from foolish ignorance or blind cupidity. Those whom they would slay, he said, were perhaps predestined by God to salvation; he cited Gregory I to the same effect and pointed out the difference between Jews and Saracens, the latter of whom make war on Christians and could justly be assailed.[263] Had the chair of St. Peter always been so worthily filled, infinite misery might have been averted and the history of Christendom been spared some of its most repulsive pages.
When the crusading spirit extended to Spain, it sometimes aroused similar tendencies. In 1108, Archbishop Bernardo of Toledo took the cross and religious exaltation was ardent. The disastrous rout of Ucles came and was popularly ascribed to the Jews in the Castilian army, arousing indignation which manifested itself in a massacre at Toledo and in the burning of synagogues. Alfonso VI vainly endeavored to detect and punish those responsible and his death, in 1109, was followed by similar outrages which remained unavenged.[264] This was a sporadic outburst which soon exhausted itself. A severer trial came from abroad, when, in 1210, the Legate Arnaud of Narbonne led his crusading hosts to the assistance of Alfonso IX. Although their zeal for the faith was exhausted by the capture of Calatrava and few of them remained to share in the crowning glories of Las Navas de Tolosa, their ardor was sufficient to prompt an onslaught on the unoffending Jews. The native nobles sought in vain to protect the victims, who were massacred without mercy, so that Abravanel declares this to have been one of the bloodiest persecutions that they had suffered and that more Jews fled from Spain than Moses led out of Egypt.[265]
