the altar of the Temple. Possession of Jewish scriptures was made a capital offense. Roman Empire The Jewish Encyclopaedia refers to the persecution of Jews and the paganization of Jerusalem during the reign of Emperor Hadrian (117-138 AD): In the Middle Ages antisemitism in Europe was religious. Many Christians, including members of the clergy, held the Jewish people collectively responsible for the killing of Jesus. As stated in the Boston College Guide to Passion Plays, "Over the course of time, Christians began to accept … that the Jewish people as a whole were responsible for killing Jesus. According to this interpretation, both the Jews present at Jesus Christ's death and the Jewish people collectively and for all time, have committed the sin of deicide, or 'god-killing'. For 1900 years of Christian-Jewish history, the charge of deicide has led to hatred, violence against and murder of Jews in Europe and America." During the High Middle Ages in Europe there was full-scale persecution of Jews in many places, with blood libels, expulsions, forced conversions and massacres. An underlying source of prejudice against Jews in Europe was religious. Jews were frequently massacred and exiled from various European countries. The persecution reached its first peak during the Crusades. In the First Crusade (1096), flourishing communities on the Rhine and the Danube were utterly destroyed, a prime example being the Rhineland massacres. In the Second Crusade (1147) the Jews in France were subject to frequent massacres. The Jews were also subjected to attacks by the Shepherds' Crusades of 1251 and 1320. The Crusades were followed by expulsions. All English Jews were banished in 1290. 100,000 Jews were expelled from France in 1396. In 1421 thousands were expelled from Austria. Many of the expelled Jews fled to Poland. As the Black Death epidemics devastated Europe in the mid-14th century, annihilating more than half of the population, Jews were taken as scapegoats. Rumors spread that they caused the disease by deliberately poisoning wells. Hundreds of Jewish communities were destroyed by violence in the Black Death persecutions. Although Pope Clement VI tried to protect them by papal bull on July 6, 1348 - with another following later in 1348 - several months afterwards, 900 Jews were burnt alive in Strasbourg, where the plague hadn't yet affected the city. One study finds that persecutions and expulsions of Jews increased with negative economic shocks and climatic variations in Europe during
