The claim that Jews abducted and murdered Christian children for alleged ritual purposes or in order to consume their blood during Passover is the most extreme of all the libels that have been used to attack Jews and present them as an existential threat to Christians. From the twelfth century to the modern era, it has been a staple of extreme antisemitic discourse seeking to dehumanize Jews and rationalize anti-Jewish violence.
In the popular mind, "Ritual Murder" and "Blood Libel" have become synonymous but in medieval times they were different accusations with different origins. Why did the accusations appear in some areas and not others? What local factors contributed to accusations receiving support from some religious or lay authorities despite papal condemnation? How have modern historians and sociologists explained the phenomenon? This book offers a critical survey of the child murder libel in medieval Europe as well as an analysis of its history.
