On a steep mound beside the River Foss in York stands Clifford’s Tower, one of the most recognizable remnants of the medieval castle that once dominated the city. Its pale stone walls belong to the thirteenth century, but the ground beneath them carries the memory of an earlier structure and one of the darkest episodes in the history of Jews in medieval England.
During the night of March 16 into March 17, 1190, members of York’s Jewish community were trapped inside the royal castle while an armed Christian crowd gathered outside. Families had fled there seeking the king’s protection after Jewish homes were attacked and burned. Instead, the castle became the site of a siege. By the following day, perhaps 150 Jewish men, women, and children were dead. Some were killed by members of their own community in what contemporary Jewish sources understood through traditions of martyrdom. Others died in the fire that consumed the wooden keep. Those who survived and came outside were murdered by the besiegers despite appeals for mercy and, according to the Christian chronicler William of Newburgh, offers to accept baptism.
The event is commonly called the Massacre at Clifford’s Tower, although the name can be misleading. The stone tower visible in York today did not yet exist. The massacre occurred in a wooden keep occupying the castle mound. The present stone structure was built decades later during the reign of Henry III.
The surviving evidence is unusually rich for a medieval massacre. Christian chroniclers recorded the violence, Jewish writers preserved the deaths as acts of martyrdom, and royal records document the political and financial aftermath. Yet none of the surviving narrative accounts was written by an eyewitness. Reconstructing what happened therefore requires placing writers such as William of Newburgh and Roger of Howden alongside the Hebrew account of Ephraim of Bonn, the elegy of Joseph of Chartres, royal administrative records, and modern scholarship.
Jews in Angevin England
Jewish settlement in England developed after the Norman Conquest. By the twelfth century, Jewish communities could be found in several important English towns, where they existed under a peculiar mixture of royal protection and royal control. Because Jewish residents depended heavily upon the Crown for legal security, their relationship with the monarchy could provide protection while simultaneously making them vulnerable to extraordinary taxation and exploitation.
Credit was central to this relationship. Medieval Christian restrictions surrounding usury contributed to an economic environment in which some Jewish financiers became important lenders to aristocrats, religious institutions, and landowners. The Crown also possessed a direct financial interest in Jewish wealth and debts. This could make prosperous Jewish families useful to the monarchy while making them deeply unpopular among debtors.
York’s Jewish community appears to have become particularly prominent during the later twelfth century. Two of its leading figures were Benedict and Josce, whose name appears in varying forms including Joceus. William of Newburgh portrayed both men as extraordinarily wealthy lenders and described their houses as being comparable in scale to royal residences. His language must be treated carefully. William condemned the massacre, but his work also contains the theological hostility toward Judaism and familiar accusations concerning Jewish moneylending that were common among medieval Christian writers. His account reveals both information about the victims and the prejudices of the society in which they lived.
Financial resentment alone, however, cannot explain what happened in York. Religious hostility, local debts, political instability, the expectation of plunder, and the emotional atmosphere created by the Third Crusade all converged during 1189 and 1190. Recent scholarship has particularly emphasized that the massacre should be understood within the longer relationship between crusading and violence against European Jewish communities.
Violence at the Coronation of Richard I
The road to York began months earlier in London.
Richard I was crowned king at Westminster on September 3, 1189. Leading Jews came to the coronation intending to present gifts to the new monarch. Among them were Benedict and Josce of York.
Their presence became the catalyst for violence.
Roger of Howden recorded that Jews were attacked near the royal court after having been forbidden from approaching during the coronation ceremonies. Benedict was beaten so severely that his attackers believed he might die. To escape, he submitted to baptism and received the Christian name William. When he later appeared before Richard, however, Benedict identified himself as a Jew and rejected the conversion that had been forced upon him. Roger, writing from a Christian perspective hostile to Benedict’s return to Judaism, nevertheless preserves the extraordinary episode. Benedict subsequently died at Northampton from the injuries he had suffered.
The violence did not remain confined to the palace. A rumor spread through London that the king had ordered the destruction of the Jews. Jewish homes were attacked and burned.
Richard had issued no such command. William of Newburgh states that the king was angered by what had taken place and attempted to restore order. Yet the events in London demonstrated how quickly anti-Jewish violence could be transformed into something that participants imagined had royal or religious approval.
Over the following months, attacks occurred elsewhere. William described violence against Jewish communities at places including Lynn and Stamford. At Stamford, he specifically connected some attackers with the crusading movement. Men preparing to travel east reasoned that the property of those they considered enemies of Christianity could help finance their journey to Jerusalem. Jews were killed, houses were plundered, and survivors sought protection in royal castles.
By March 1190, the violence had reached York.
The Attack on York’s Jewish Houses
William of Newburgh provides the fullest surviving Christian account of what followed. His monastery stood in Yorkshire, and he wrote within a few years of the massacre, but even his detailed narrative was not eyewitness testimony. It is therefore best read in comparison with other evidence rather than accepted word for word.
According to William, a group of men in Yorkshire had already conspired against the Jews. Among those encouraging the violence were people who owed substantial sums to Jewish creditors. He also associated some participants with the crusading movement and the prospect of obtaining money before departing for Jerusalem.
A fire broke out in York. Whether accidental or deliberately started as a diversion was uncertain even to William. While townspeople were occupied with the danger, an armed group entered Benedict’s house. Benedict himself was already dead from the injuries received in London, but his wife, children, and others remained there. William wrote that the attackers killed those inside, robbed the property, and set the building on fire.
The assault sent a clear message to the remaining Jewish families.
Josce and other members of the community sought protection from the keeper of York Castle. They moved themselves, their families, and whatever property they could carry into the royal fortress. Soon afterward, Josce’s own house was attacked, looted, and burned.
Those who remained outside faced an impossible choice. William claimed that Jews encountered by the attackers were offered baptism or death. Some submitted to conversion in order to survive. Others were killed.
The royal castle, at least temporarily, appeared to offer safety.
Refuge Becomes a Siege
Royal castles could serve as places of refuge because Jews were under the protection of the king. Similar action at Lincoln had apparently prevented greater bloodshed there. In York, however, the sanctuary quickly became a trap.
According to William, the keeper of the castle left temporarily on official business. When he attempted to return, the frightened Jews inside refused him admission. They could no longer know whom to trust, and apparently feared that the official responsible for protecting them might be pressured or bribed into opening the fortress to their enemies.
The castle keeper then complained to the sheriff or royal authority in the county that he had been deprived of control over the king’s castle. What had begun as a desperate attempt at self-preservation could now be represented as unlawful occupation of a royal fortress.
An order was given for the castle to be recovered.
The consequences were immediate. Armed men gathered from York and the surrounding area. William wrote that the official responsible soon attempted to withdraw the order, but the crowd could no longer be controlled. Citizens, countrymen, soldiers, laborers, young men, and members of the clergy were among those who joined the siege.
The Jews who had entered the castle hoping to be protected by royal authority were now surrounded partly in the name of that same authority.
Religion Outside the Castle Walls
Among the most disturbing figures in William’s account is a Premonstratensian hermit who joined the attackers.
Dressed in the white habit of his order, the priest reportedly moved among the besiegers encouraging the assault as a religious act. William presents him shouting against those he considered enemies of Christianity and personally helping with the siege machinery.
The chronicler did not approve.
William claimed that the hermit was struck and killed by a stone thrown from the castle. To William, his death represented divine judgment against a priest who had mistaken murder for religious devotion.
This part of the narrative is important because it demonstrates the contradictions within medieval Christian reactions to anti-Jewish violence. William himself expressed theological anti-Judaism and repeated deeply hostile stereotypes about Jews, yet he simultaneously insisted that Christians had no lawful or religious right to kill them. The same text can therefore condemn the perpetrators while preserving prejudices that helped create the environment in which the violence became possible.
That distinction is essential when using Christian chronicles as evidence.
The attackers were not simply participating in a financial dispute. At least some understood what they were doing through religious categories associated with Christianity, crusading, conversion, and the struggle against those defined as enemies of the faith. Modern historian Christoph T. Maier has consequently argued that York belongs within the wider history of crusading violence against European Jews, not merely the history of local indebtedness.
The Final Night in the Wooden Keep
The siege continued for several days. Those inside had limited provisions and few weapons. William wrote that they defended themselves with stones pulled from the fortifications while the attackers prepared siege engines.
Eventually the people inside concluded that the castle could not be held.
What happened next is preserved through both Christian and Jewish traditions.
William wrote that a respected Jewish teacher addressed the community and urged them to die rather than abandon Judaism through forced conversion. The long speech that William places in the teacher’s mouth should not be treated like a transcript. Medieval historians regularly composed speeches for historical figures, and modern scholars have examined the extent to which William shaped his account through older literary models, including Josephus’s history of the Jewish revolt against Rome.
Behind the literary construction, however, stands an event also remembered independently in Jewish sources.
The teacher was Rabbi Yom Tov of Joigny, a French-born scholar associated with the York community. The Hebrew chronicler Ephraim of Bonn remembered him by name. Ephraim recorded that approximately 150 Jewish men and women died at York and wrote that Yom Tov killed sixty before others continued the act. Some, he said, commanded that their own children be killed rather than fall into the hands of their persecutors, while others died in the fire.
William’s version describes the heads of households killing their wives and children before being killed themselves. He singles out Josce, who he says killed his wife Anna and their children before being killed in turn. The interior of the keep was then set on fire.
The two accounts differ in language, theology, details, and purpose, but both preserve the central memory of Jews choosing death within the besieged fortress rather than surrendering to a crowd that had already presented conversion and death as alternatives.
Martyrdom in the Jewish Sources
The Hebrew evidence allows the massacre to be seen from beyond the perspective of the Christian chroniclers.
Ephraim of Bonn described York as “Evoric” and placed the killings around the Great Sabbath before Passover. His narrative does not portray the deaths as inexplicable self-destruction. They were remembered within a religious tradition of martyrdom, in which death could be preferable to forced abandonment of Judaism.
Ephraim also records something the Christian accounts cannot fully recover: the cultural destruction accompanying the violence. Jewish houses were destroyed and property was taken, but valuable Hebrew books were also looted. He remembered books of exceptional beauty being carried away and later sold back into Jewish hands on the European continent.
Another Jewish voice survives in the elegy written by Joseph of Chartres for the martyrs of York. Composed during the late twelfth century, the poem commemorates the dead in explicitly religious language and remembers Yom Tov among them. It is not a chronicle attempting to provide a neutral sequence of events. It is a lament written to preserve the victims within Jewish communal memory.
Together, these Hebrew sources are indispensable. Without them, the destruction of York’s Jewish community would be reconstructed almost entirely through Christian authors who viewed Judaism through a hostile theological framework.
Those Who Chose to Leave the Castle
Not everyone inside agreed to die.
William of Newburgh says that some separated themselves from those who accepted Yom Tov’s advice. They attempted to survive the fire during the night and were still alive when the attackers gathered the following morning again.
From the battlements, according to William, the survivors told the crowd what had happened and asked to be allowed to leave. They offered to receive Christian baptism.
Whether their willingness to convert was genuine, coerced by terror, or simply the last available strategy for survival cannot be known. William himself acknowledged the uncertainty.
The attackers promised them mercy.
The survivors came out.
They were killed.
William, despite the anti-Jewish language elsewhere in his chronicle, condemned the murder unequivocally. He accused the attackers not only of unlawful killing but of deception because they had promised safety before murdering those who surrendered.
The violence had therefore moved beyond the stated justification of conversion. Even Jews who offered to become Christians were not spared.
Burning the Debts
The massacre did not end when the last survivors were killed.
The attackers proceeded to York Minster, where documents recording debts owed to Jewish creditors had been deposited. William states that the custodians were forced to surrender these records.
The documents were burned.
This act provides one of the clearest indications that economic self-interest was intertwined with religious violence. Killing Jewish creditors was one thing. Destroying the records of what Christians owed them could erase obligations that otherwise might pass to heirs or, because of the Crown’s financial rights over Jewish assets, become matters of royal interest.
William explicitly connected influential conspirators with substantial debts. The deliberate destruction of debt records after the massacre gives his claim added significance.
The York massacre therefore cannot be reduced to a single cause. Anti-Jewish theology, crusading enthusiasm, local political disorder, resentment toward lenders, indebtedness, the possibility of plunder, and the weakness of royal authority during Richard’s absence all interacted.
Religious hatred could sanctify economic motives, while financial interests could give individuals practical reasons to encourage religious violence.
Richard I Responds
Richard I was outside England when news of York reached him.
William of Newburgh says the king was furious. The massacre represented an assault upon people who were supposed to be under royal protection, but it also damaged royal finances. Jewish wealth and outstanding debts were intimately connected to the interests of the Crown.
Richard ordered William Longchamp, bishop of Ely and royal chancellor, to investigate.
Longchamp traveled north with an armed force. By the time he arrived, however, some of the leading perpetrators had fled. William records that certain ringleaders escaped into Scotland, while townspeople denied responsibility for the actions of the mob.
Fines were eventually imposed, and officials were removed, but William concluded his account by observing that no individual had been executed or otherwise judicially punished for the massacre itself.
Royal protection had failed before the massacre. Royal justice largely failed afterward.
Yet the Crown did not simply abandon its relationship with England’s Jews.
Only days after the York killings, on March 22, 1190, Richard issued a charter confirming liberties and protections previously granted to Jews under Henry II. The charter affirmed rights concerning residence, movement, property, pledges, and royal protection. It provides a striking documentary counterpoint to the destruction at York.
The Ordinances of the Jews and the Financial Aftermath
The vulnerability of Jewish financial records during the violence of 1189 and 1190 had exposed a serious problem for the monarchy. If debt records could simply be destroyed, the Crown could lose income along with the Jewish creditor.
In 1194, royal government introduced a more organized system for registering Jewish financial transactions.
The Ordinances of the Jews required debts, mortgages, pledges, and related property transactions to be recorded. Contracts were to be duplicated, with one copy deposited in a common chest secured by multiple locks and supervised by both Jewish and Christian officials. These chests became known as archae.
The system served several purposes. It protected records from destruction, strengthened royal oversight, and allowed the Crown to monitor a financial network in which it had substantial interests.
York’s burned documents had shown how quickly both private debts and royal revenue could disappear in a riot. The administrative reforms that followed were therefore part of the broader legacy of the massacres of 1189 and 1190.
York After the Massacre
The destruction of 1190 did not permanently end Jewish life in York.
Jewish settlement reappeared in the city within a relatively short period, a reminder that medieval Jewish history in York cannot be reduced entirely to the massacre. A community again participated in the commercial and financial life of the city during the thirteenth century.
Yet the fundamental insecurity of Jewish life in medieval England remained.
Jews possessed royal protection because the monarchy found their presence useful, but the same legal dependence gave the Crown enormous authority over their lives and property. Periods of protection alternated with taxation, coercion, hostility, and violence.
A century after the massacre, the situation reached another decisive point. In 1290, Edward I ordered the expulsion of Jews from England. Organized Jewish communal life would not be formally reestablished in England until the seventeenth century.
Clifford’s Tower Was Not the Tower of 1190
The name Clifford’s Tower has become inseparable from the massacre, but historically it requires explanation.
The building that dominates the mound today was not standing when York’s Jews sought refuge there.
The Norman castle established after the Conquest relied largely upon timber defenses. It was a wooden keep on the mound that sheltered the Jewish community in 1190 and burned during the final night of the siege.
The surviving stone tower belongs to a later phase of royal construction. Architectural and documentary research places it in the mid-thirteenth century, during the reign of Henry III.
Calling the event the “Clifford’s Tower massacre” is therefore understandable because the modern landmark identifies the location, but it should never suggest that the victims died inside the stone building visitors enter today. The tower is a later monument standing over the site of the earlier tragedy.
Christian Chronicle and Jewish Memory
One of the most important aspects of the York massacre is the unusual ability to compare different medieval memories of the same event.
William of Newburgh gives the most detailed continuous narrative. He identifies individuals, debts, houses, the castle keeper, the crowd, the hermit, the siege, the deaths within the keep, the murder of survivors, the destruction of debt records, and the royal investigation.
Yet William was a Christian cleric writing within a culture of theological anti-Judaism. He condemns the murderers while describing Judaism in language that modern readers should recognize as prejudiced. His work is invaluable, but it is not neutral.
Roger of Howden provides another contemporary Christian tradition, while royal financial documents offer evidence produced for administration rather than storytelling. English Heritage’s historical bibliography identifies William, Howden, Ralph of Coggeshall, the Chronicle of Meaux, and Pipe Rolls among the principal documentary sources for reconstructing the castle and massacre.
Ephraim of Bonn and the Hebrew elegies provide something different. They remember the victims from within medieval Jewish culture, preserving the massacre through language of martyrdom, communal suffering, sacred books, and faithfulness to Judaism.
Neither tradition should simply be laid over the other. Their differences are part of the history.
Remembering the Jews of York
Around 150 people are generally believed to have died during the destruction of York’s Jewish community. Some medieval Christian sources offer much higher numbers, but the approximately 150 remembered by Ephraim of Bonn has become the figure most commonly accepted in modern accounts. Modern scholarship likewise places the death toll at around that level.
Numbers, however, can obscure what the surviving sources reveal.
These were families.
William gives the names of Josce and his wife Anna. Jewish sources preserve Rabbi Yom Tov. Benedict’s story can be followed from York to the violence at Richard’s coronation and finally to his death from his injuries. Joseph of Chartres transformed the dead into the subjects of a lament that carried their memory beyond England.
The massacre also destroyed a community’s property, homes, manuscripts, financial networks, and sense of security.
For that reason, York has remained one of the defining places in the history of medieval Anglo-Jewry. Barrie Dobson’s landmark study of the Jews of medieval York remains foundational, while the later collection Christians and Jews in Angevin England: The York Massacre of 1190, Narratives and Contexts has placed the event within its urban, religious, economic, literary, and political settings. More recent work has continued to emphasize that York must also be understood against the international background of crusading and anti-Jewish violence.
The ground beneath Clifford’s Tower therefore preserves more than the story of a medieval castle. It marks the place where royal protection collapsed, private debts became motives for destruction, crusading religion was turned against a Jewish community, and families found themselves forced to choose among conversion, surrender, and death.
The stone tower came later.
The memory beneath it belongs to March 1190.
