Antisemitic canard

"The blood libel accusation, another famous anti-Semitic canard, is also a twelfth-century creation."^[70] The first recorded ritual murder accusation against Jews was that of William of Norwich, reported by a monk Thomas of Monmouth.^[71]

The descriptions of torture and human sacrifice in the antisemitic blood libels run contrary to many of the teachings of Judaism. The Ten Commandments forbid murder. The use of blood (human or otherwise) in cooking is prohibited by Kashrut and blood and other discharges from the human body are considered ritually unclean. (Lev 15) The Bible (Old Testament) and Jewish teachings portray human sacrifice as one of the evils that separated the pagans of Canaan from the Hebrews. (Deut 12:31, 2 Kings 16:3) Jews were prohibited from engaging in these rituals and were punished for doing so (Ex 34:15, Lev 20:2, Deut 18:12, Jer 7:31). Ritual cleanliness for priests prohibited even being in the same room with a human corpse (Lev 21:11).

When "Church and secular leaders sharply denounced these defamations ... people refused to abandon this myth ... Popes, kings and emperors declared that Jews, if for no other reason than their strict dietary laws banning even the smallest drop of blood in meat or poultry, were incapable of the crime. The Christian populace was not impressed. In 1385, Geoffrey Chaucer published his Canterbury Tales which included an account of Jews murdering a deeply pious and innocent Christian boy. This blood libel became a part of English literary tradition."^[72]

Among those who refuted the blood libel against Jews were Holy Roman Emperor Frederick II in 1236: "we pronounce the Jews of the aforementioned place [Fulda] and the rest of the Jews in Germany completely absolved of this imputed crime";^[73] Pope Gregory IX in Papal Bull dated 7 October 1272: "We decree ... that Christians need not be obeyed against Jews in a case or situation of this type, and we order that Jews seized upon such a silly pretext be freed from imprisonment, and that they shall not be arrested henceforth on such a miserable pretext, unless – which we do not believe – they be caught in the commission of the crime";^[74] Pope Clement VI on 26 September 1348: "Jews are not responsible for the Plague."^[75]

Blood libel stories have appeared in modern times on many occasions in the state-sponsored media of a number of Arab and Muslim nations, their television shows and websites, and books alleging instances of the Jewish blood libels are not uncommon there.^[76]
