# The blood libel is the false, antisemitic medieval myth that Jews murder Christians, especially children, to use their blood in religious rituals

**Verdict: Contradicted.** The blood libel is a debunked antisemitic hoax, and this file rates it as such without qualification. It is the false claim, spread since twelfth-century England, that Jews ritually murder Christians (above all children) to drain their blood for religious use, such as baking Passover matzah. There is no truth in it. Jewish law forbids the consumption of blood outright, matzah is made only from flour and water, and not one of the roughly one hundred accusations documented between the twelfth and sixteenth centuries produced a genuine victim of any such ritual; the confessions that condemned entire Jewish communities were extracted under torture. Multiple popes, from Innocent IV in 1247 to Gregory X in 1272, formally rejected the charge as baseless, and an eighteenth-century Vatican inquiry reached the same conclusion. The libel is important not because it is credible but because it is lethal: it drove centuries of massacres, resurfaced in Nazi propaganda, and survives today, repackaged, inside modern conspiracy theories about elites harvesting children's blood.

## Summary
The blood libel is one of the oldest and deadliest antisemitic lies: the false claim that Jews kidnap and murder Christians, especially children, to use their blood in rituals, most often to bake unleavened bread for Passover. It began in Norwich, England, in 1144, when a monk named Thomas of Monmouth accused local Jews of ritually killing a boy, and spread across Europe in roughly one hundred documented cases over the next four centuries. Each was a fabrication, yet the accusations triggered torture, mass executions, and pogroms. The charge is not merely unproven but affirmatively false: Jewish dietary law strictly forbids consuming blood, and popes and scholars debunked it repeatedly across the centuries. This file exists to report the hoax and its harm, and to name it plainly for what it is. It never treats the accusation as true; the target throughout is the myth, never Jewish people.

## The claim
That Jews, as a secret religious practice, abduct and kill Christians, especially children, in order to harvest their blood for ritual use such as baking Passover matzah or preparing wine, and that this supposed crime has been carried out repeatedly across history. Stated in the believer's own terms, the myth casts an entire religious community as ritual murderers acting on a hidden theological command. This file states that claim only in order to identify and refute it.

## Origin and timeline
- 1144: In Norwich, England, a young boy named William is found dead. Around this time the monk Thomas of Monmouth begins asserting that local Jews tortured and murdered the boy in mockery of the crucifixion. His hagiography, The Life and Passion of William of Norwich, becomes the founding text of the ritual-murder accusation in Europe. No evidence ever connected any Jew to the death.
- 1255: In Lincoln, England, the death of a boy later venerated as “Little Saint Hugh” is blamed on the town's Jews. Roughly ninety Jews are arrested and around nineteen are executed. The case shows how quickly the fabricated charge could move from rumor to state killing.
- 1475: In Trent, in what is now northern Italy, a toddler named Simon disappears near Easter. The entire local Jewish community is arrested, tortured into confessions, and executed, and a saint's cult grows up around the boy. The Catholic Church suppressed that cult only in 1965, formally acknowledging the accusation had been false.
- 1247: Pope Innocent IV issues the bull Lachrymabilem Judaeorum, condemning the ritual-murder charge and ordering an end to the persecution it fueled. It is among the earliest formal rejections of the libel by a Christian authority, and it is followed by similar interventions from later popes, including Gregory X in 1272.
- 1840: In the Damascus affair, a Capuchin friar and his servant vanish, and members of the city's Jewish community are accused of killing them for their blood. Several prominent Jews are imprisoned and tortured to extract confessions, in a case that draws international protest and marks the libel's spread beyond Europe.
- 1911–1913: In the Russian Empire, Menahem Mendel Beilis, a Jewish factory worker in Kiev, is arrested and tried for the alleged ritual murder of a Christian boy. After a trial that drew worldwide attention to Russian antisemitism, a jury acquits him in 1913. The prosecution had rested on the ancient libel rather than on evidence.
- 1934: In Nazi Germany, Julius Streicher's newspaper Der Stürmer publishes a notorious special “ritual murder” issue reviving the blood libel as state-aligned propaganda, complete with lurid caricatures of Jews draining children's blood. Streicher is later convicted at Nuremberg and executed in 1946 for incitement.
- 1946: In Kielce, Poland, a false rumor that Jews had kidnapped a Christian boy sets off a pogrom that kills 42 Jewish Holocaust survivors, though the building at the center of the rumor had no cellar in which the alleged captivity could have occurred. It is one of the deadliest postwar expressions of the myth.
- 2016–present: The libel resurfaces, repackaged, in online conspiracy movements. Pizzagate, the “adrenochrome” narrative, the Wayfair trafficking hoax, and QAnon all recycle the core structure of the blood libel: a hidden elite said to harvest or consume children's blood. The ADL and other monitors identify these as modern descendants of the medieval charge.

## The evidence, claim by claim
- Claim: The myth holds that Jews need Christian blood to bake Passover matzah.
  Evidence: This is false on its face. Matzah is unleavened bread made only from flour and water, baked quickly and specifically without additives; there is no ingredient in it that the accusation describes. The claim survives because most people who repeat it have never examined what the ritual it invokes actually involves.
- Claim: The accusation asserts a secret Jewish religious command to use human blood.
  Evidence: Jewish law forbids the opposite. The consumption of blood is explicitly and repeatedly prohibited in the Hebrew Bible (Leviticus 17 among other passages), and kosher slaughter is built around draining and removing blood from meat. A faith that treats blood as forbidden cannot coherently be said to require it for ritual. The libel inverts an actual religious rule into its exact opposite.
- Claim: Roughly a hundred cases across the centuries show a real pattern of ritual killings.
  Evidence: The pattern they show is one of fabrication, not of crime. Historians count on the order of a hundred blood-libel accusations from the twelfth to sixteenth centuries, and in each the “proof” consisted of confessions extracted under torture, coincidence, or the word of a single accuser. Not one produced a genuine ritual victim. A recurring accusation is not evidence of a recurring act; here it is evidence of a recurring slander.
- Claim: Church and state authorities took the charge seriously, so it must have had substance.
  Evidence: Where authorities examined the charge rather than exploiting it, they rejected it. Pope Innocent IV condemned it in 1247, Gregory X forbade prosecutions based on it in 1272, and in the eighteenth century a Vatican inquiry associated with Cardinal Lorenzo Ganganelli, later Pope Clement XIV, again found the accusation baseless. That popes had to keep debunking it shows how persistent the lie was, not that it was ever true.
- Claim: Some accused people confessed, which believers cite as an admission of guilt.
  Evidence: The confessions are worthless as evidence because of how they were obtained. In case after case, from Trent in 1475 to Damascus in 1840, the accused were tortured until they said what their accusers wanted. Confession under torture is a confession to the torture, not to the crime. Modern trials that actually tested the charge, such as the 1913 Beilis case in Kiev, ended in acquittal once evidence rather than coercion was required.
- Claim: Modern versions about elites harvesting children's blood are a separate, new concern.
  Evidence: They are the same myth in new clothing. The adrenochrome narrative, Pizzagate, the Wayfair hoax, and QAnon all reproduce the blood libel's essential structure: a secret, powerful cabal accused of murdering children to extract their blood. The ADL and researchers of extremism identify these directly as descendants of the medieval charge, which is why debunking the old libel and debunking its modern mutations is a single task.
- Claim: The accusation is just an old story with no real-world consequences today.
  Evidence: Its consequences are among the best-documented in the history of antisemitism. The libel drove medieval massacres, expulsions, and the Damascus and Beilis affairs; it was weaponized by Nazi propaganda; and it produced the 1946 Kielce pogrom, in which 42 Jewish survivors of the Holocaust were murdered over a rumor. Treating it as harmless folklore is precisely the error that lets it keep killing.

## Why people believe it
- It is old enough to feel like received tradition. A charge repeated for nearly nine centuries acquires a false authority simply through age and repetition; people encounter it as something “everyone used to say” and mistake longevity for evidence.
- It offers a ready scapegoat in a crisis. When a child died unexpectedly in a medieval town, or when postwar Poland was in turmoil, the libel supplied an outside villain to blame, channeling grief and fear onto a vulnerable minority instead of onto the harder, unglamorous truth.
- It fuses horror and secrecy, which makes it viscerally sticky. A hidden ritual involving murdered children is engineered, whether the tellers intend it or not, to provoke revulsion and to resist disproof: any absence of evidence can be recast as proof of how well the secret is kept.
- It has been deliberately propagated by people with power to gain. Clergy building saint cults, empires deflecting unrest, and Nazi propagandists all had reasons to spread it. The myth persists partly because, for its promoters, it worked.

## Open questions
- The real question is not whether the libel is true, which it is not, but why it is so durable. Scholars study how a single accusation in one English town became a portable template that could be dropped into new places and centuries, and what that says about how societies manufacture and reuse scapegoats.
- How the medieval charge mutated into today's online conspiracy theories is an active area of research. Tracing the line from William of Norwich to adrenochrome and QAnon helps explain why debunking the surface claim is rarely enough: the underlying structure keeps finding new hosts.
- Why formal debunkings, including repeated papal condemnations, failed to kill the myth is a genuinely instructive problem. It suggests that authoritative refutation alone does not dislodge a belief that serves emotional and political needs, a lesson that applies well beyond this one libel.
- What actually protects a targeted community is the harder open question. The history here (massacres that official rejections did not prevent) is studied precisely to understand how debunking, education, and law can be made to work faster than the rumor does.
