The original antisemitic blood libel dates from the Middle Ages, and is the accusation that Jews murder Christian children in order to use their blood in Passover rituals. In 1290, it was the pretext for the confiscation of all Jewish property and the complete expulsion of Jews from England. They were not permitted to return until 1655. Blood libel has been responsible for the persecution and killing of Jews ever since.
In the modern era, blood libel continues to be a major aspect of antisemitism. It has extended its reach to accuse Jews of many different forms of harm that can be carried out against other people. The major manifestations of blood libel are listed below.
