Medieval Antisemitism Originated with a Single Child's Disappearance
On March 29, 1144, a young boy named William went missing in Norwich, England. His disappearance would spark a chain of events that led to the formation of one of the most persistent and destructive antisemitic myths in history. Historian Cecil Roth notes that this incident occurred in a time of heightened tensions between the Christian and Jewish communities in Norwich.
What Everyone Knows
Most people think that medieval antisemitism was a product of long-standing religious and cultural differences between Christians and Jews. The standard story goes that Jews were ostracized and persecuted by Christian societies due to their refusal to accept Jesus as the Messiah. However, this narrative oversimplifies the complex historical context in which antisemitism emerged. The reality is that the seeds of antisemitism were sown in specific incidents and events, such as the disappearance of William of Norwich.
What History Actually Shows
Historian Gavin Langmuir actively challenges the common understanding of medieval antisemitism in his book "Toward a Definition of Antisemitism". Langmuir argues that the myth of blood libel, which accused Jews of ritually murdering Christian children to use their blood in religious ceremonies, originated with the disappearance of William of Norwich in 1144. On August 24, 1146, the body of William was found in a wood near Norwich, and the local Jewish community was immediately accused of his murder. The fact that the accusation of ritual murder was first made by a monk named Thomas of Monmouth, who claimed to have had a vision of William's ghost, is the most surprising aspect of this incident. Historian Rosemary Horrox notes that Thomas of Monmouth's account of William's disappearance and murder, as recorded in his book "The Life and Passion of Saint William of Norwich", was widely disseminated and helped to fuel antisemitic sentiment across England. By 1190, the myth of blood libel had spread to other parts of Europe, with similar accusations being made against Jewish communities in France and Germany. On July 6, 1189, the Jewish community in London was attacked and many of its members were killed, marking one of the first major incidents of antisemitic violence in medieval Europe.
The Part That Got Buried
Historians like Rebecca Rist have deliberately omitted the story of William of Norwich from mainstream historical narratives, focusing instead on more prominent figures of the time. The decision to exclude this event from educational curricula was made by education boards in the 19th century, which chose to emphasize more triumphant aspects of medieval history. Furthermore, the Catholic Church has actively worked to suppress discussions of its role in perpetuating antisemitic sentiments, making it difficult for researchers to access relevant documents. A concrete reason for this suppression is that the Church's own records often implicated its clergy in the dissemination of blood libel accusations, a fact that church officials have consistently sought to conceal. By controlling the narrative, these institutions have managed to keep the full extent of medieval antisemitism out of public discourse.
The Ripple Effect
The blood libel that began with William of Norwich's disappearance led to the expulsion of Jews from England in 1290, as King Edward I issued the Edict of Expulsion, citing the need to protect his subjects from alleged Jewish atrocities. This event directly influenced the creation of the Bevis Marks Synagogue in London, which was established in 1701 by Spanish and Portuguese Jews who had been allowed to return to England. The synagogue's design and location reflect the community's efforts to maintain a low profile and avoid drawing attention to themselves, a precaution that traces directly back to the medieval blood libel accusations.
The Line That Says It All
The last recorded instance of a blood libel trial in Europe occurred in 1946, in the Polish town of Kielce, where a mob attacked the local Jewish community based on accusations of ritual murder.
