the Jews of Strassburg after a community debate. In 1391, Ferrand Martinez, archdeacon of Ecija, began a campaign against Spanish Jewry, killing over 10,000 and destroying the Jewish quarter in Barcelona. The campaign quickly spread throughout Spain, except for Granada, and destroyed Jewish communities in Valencia and Palma De Majorca. King Pedro I ordered Spain not to harm the remaining Jews and that synagogues not be converted into churches. He then announced his compliance with the Bull of Pope Boniface IX, protecting Jews from baptism. He extended this edict to Spanish Jewish refugees. Benedict XIII banned the study of the Talmud in any form, as institutions forced Christian sermons and tried to restrict Jewish life completely, and a few years later Pope Martin V favorably reinstated old privileges of the Jews. After more Jews were expelled from France, some remained in Provence until 1500. In 1422, Pope Martin V issued a bull reminding Christians that Christianity was derived from Judaism and warned the Friars not to incite against the Jews, but the Bull was withdrawn the following year. By the end of the 15th century, the Inquisition was established in Spain. Around 1500 Jews found relative security and a renewal of prosperity in present-day Poland. The Crusades The trials the Jews periodically endured in the various Christian West kingdoms echoed the catastrophes that occurred during Crusades. In the First Crusade (1096) flourishing communities on the Rhine and the Danube were utterly destroyed. Furthermore, there were also attacks on the Jews that lived in cities along the Rhine. Prior to these attacks, many Jews were seen as integral members of society despite religious differences. Many Jews worked in the money lending trade. Their services allowed for societies to function financially. In one case Jewish moneylenders were responsible for financially maintaining a monastery. Without these loans the monastery would have been unable to survive. However, this fiscal responsibility that the Jews carried might have caused tensions amongst the middle and upper class. These sects of society would not have approved of the power that the Jewish communities held. At this point there were no strictly Jewish communities. Jews were not concentrated in one area, rather their presence was spread over a larger geographical region. Oftentimes a few families lived immersed in a predominantly Christian settlement. The Jewish families were comfortable in this setting and functioned successfully. In some circumstances, Christians both accepted
