The Etiology of Blame: A Comprehensive Historical and Sociological Analysis of Antisemitic Scapegoating During Epidemiological Crises

Executive Summary

The intersection of epidemiological crisis and social upheaval has, for nearly a millennium, produced a consistent and violent sociological phenomenon: the scapegoating of the Jewish minority. This report provides an exhaustive analysis of this historical trajectory, tracing the evolution of blame from the theological accusations of the Middle Ages to the racialized eugenics of the 20th century and the conspiratorial networks of the digital age.

The historical record demonstrates that the mechanism of blaming Jews for disasters is not static; it mutates to fit the epistemological framework of the era. In the 14th century, during the Black Death, the accusation was one of active malice—well poisoning—framed within a religious worldview. By the 19th century, with the advent of germ theory and the rise of the nation-state, the accusation shifted to one of passive danger—the Jew as a carrier of "Asiatic" filth and disease, threatening the sanitary order of the modern state. In the Nazi era, this metaphor was literalized, with the Jew equated to the louse and the bacillus, justifying genocide as a public health measure. Finally, in the 21st century, the COVID-19 pandemic has seen a synthesis of these ancient tropes with modern technophobia, resulting in conspiracies regarding bioweapons, globalist control, and vaccination plots.

This report synthesizes historical data, primary source documents (including papal bulls, city council minutes, and personal diaries), archaeological findings, and modern sociological theories (such as Parasite Stress Theory and Terror Management Theory) to explain why the Jew remains the perpetual "Other" in times of biological threat. It further explores the economic drivers of persecution, particularly the "fiscal overfishing" of Jewish communities in the Holy Roman Empire, and contrasts the violent responses to plague and cholera with the anomalous lack of antisemitic violence during the 1918 Influenza pandemic.

Section I: The Medieval Paradigm: Theology, Poison, and the Black Death

The Black Death (1347–1351) represents the archetype of conspiratorial antisemitism. The arrival of Yersinia pestis in Europe caused a demographic collapse of unprecedented scale, killing between one-third and one-half of the population. In the absence of a scientific explanation, European society sought a cause that was tangible and punishable. The result was the "Great Mortality" not only of the general populace but of the Jewish communities of Western Europe.

1.1 The Great Mortality and the Search for Causality

To understand the violence of 1348, one must first understand the intellectual climate of the 14th century. The prevailing medical theory was the Galenic concept of miasma—corrupted air that disrupted the humors of the body. However, the suddenness and lethality of the plague defied traditional medical explanations. People sought an agent, a "poisoner," who could be held responsible for corrupting the elements.

While the official policy of the Church was to protect Jews—reasoned in part because Jesus was Jewish—the popular response was driven by a desperate need for explanation.1 As the plague swept north from the Mediterranean, the psychological trauma of mass death dismantled social norms. The populace, terrified by an incomprehensible horror, turned to superstition and hysteria. In this vacuum of reason, the Jew, already marginalized as a theological enemy and an economic competitor, became the ideal scapegoat.2

1.2 The Well-Poisoning Libel: Origins and Mechanisms (1348)

The primary accusation levied against the Jews was that they were poisoning the wells and springs of Christendom to destroy the Christian population. This accusation was structurally distinct from previous blood libels; it was not a ritual crime but an act of biological warfare. The "poisoning" narrative provided a comforting illusion of control: if the plague was a natural disaster or divine punishment, it was unstoppable; if it was a conspiracy, the conspirators could be eliminated, and the plague halted.

The accusations often alleged a centralized conspiracy. Suspicions arose that minority groups wished to destroy the Christian majority by poisoning water sources, a plot supposedly initiated by Jewish leadership in cities like Toledo or Chambery.3 The evidence for these crimes was invariably manufactured through torture.

The Confession of Agimet:

A pivotal document from this era details the confession of a Jew named Agimet, who was coerced into confessing that he had been given a packet of poison by a "Rabbi Peyret." Agimet's confession was detailed and specific, designed to lend credibility to the conspiracy. He claimed to have carried a package full of poison to Venice, where he scattered it into the well or cistern of fresh water near the German House. Crucially, the confession notes that "this is the only cistern of sweet water in the city," implying a targeted tactical strike against the population's most vulnerable resource.2

Agimet further "confessed" to traveling to Calabria, Apulia, and Toulouse to poison wells there. The confession included details about the composition of the poison—often described as a mixture of spiders, frogs, lizards, and sacred hosts—blending folk magic fears with blasphemy. This document was not merely a record of torture; it was a piece of propaganda, circulated rapidly between city councils to justify preemptive action in towns where the plague had not yet arrived.2

1.3 Case Study: The Destruction of Rhineland Jewry (Strasbourg & Cologne)

The violence was most intense in the German-speaking lands of the Holy Roman Empire, specifically along the Rhine. In cities like Strasbourg, Cologne, and Erfurt, the destruction of Jewish communities was not merely the result of spontaneous mob violence but often a calculated political act organized by guilds and city councils.

The Strasbourg Massacre (February 14, 1349):

The events in Strasbourg reveal the intersection of epidemiological fear and political revolution. The city's patrician government initially sought to protect the Jews, conducting an investigation that found no evidence of well poisoning. The deputies of Strasbourg famously declared they "knew no evil of them".4 However, this stance was unpopular with the trade guilds and the lower classes, who were agitated by fear and debt.

A coup ensued. The master tradesmen, supported by the populace, overthrew the patrician council. The new government, installed on a platform of persecution, moved quickly. On St. Valentine's Day, February 14, 1349—before the plague had heavily infected the city—the Jews of Strasbourg were arrested. They were led to the Jewish cemetery, where a wooden house had been constructed. There, approximately 2,000 Jews were burned alive.2

The massacre was characterized by its methodical nature. Those willing to be baptized, as well as "attractive" women and children, were sometimes spared, but the community as a distinct entity was annihilated. The chronicle of Jakob Twinger von Königshofen records that the massacre lasted six days. Following the murders, the council distributed the Jews' property among the conspirators and cancelled all debts owed to Jewish moneylenders, revealing the stark economic incentives behind the "medical" purge.5

1.4 The Basel Massacre: Pre-emptive Cleansing

In Basel, the violence followed a similarly grim trajectory but occurred even earlier, in January 1349. As in Strasbourg, the driving force was the guilds, who forced the city council to act. The city's Jews were herded into a specially constructed wooden structure on an island in the Rhine and burned.7

The Basel massacre is particularly notable for its "prophylactic" logic. The city had not yet been devastated by the plague, but the population believed that by eliminating the perceived source of the "poison," they could immunize the city. This pre-emptive cleansing extended to the converted; even baptized Jews were sometimes targeted, suspected of retaining their allegiance to the "poisoning plot." Children were often spared the fire but were forcibly baptized and sent to monasteries, effectively erasing the demographic future of the Jewish community in the region.7

1.5 The Papal Defense and the Limits of Authority (Avignon)

It is a profound historical irony that during the Black Death, the Catholic Church's highest authority was one of the few voices defending the Jews. Pope Clement VI, reigning from Avignon, issued two papal bulls in 1348, the most famous being Quamvis Perfidiam.

In this text, Clement VI deconstructed the conspiracy theory with empirical logic. He argued that the Jews could not be responsible for the plague because "the plague has afflicted and afflicts the Jews themselves and many other races who have never lived alongside them".8 He condemned the violence, stating that those who blamed the Jews had been "seduced by that liar, the Devil."

The Geography of Papal Power:

Clement VI actively provided protection to Jews within Avignon, saving the community there. However, his writ ran limitedly outside the Papal States. In the frenzy of 1349, local clergy, flagellant movements, and city councils in Germany often ignored the Pope. The Flagellants, who roamed from town to town whipping themselves in penance, acted as a super-spreader event for both the disease and antisemitic violence. They preached that the Jews were enemies of Christ who must be destroyed to appease God's wrath, viewing the Pope's protection as a sign of corruption.1

1.6 Economic Drivers: Debt, Regicide, and Fiscal Overfishing

While the accusations were framed in medical or demonological terms, the underlying drivers were frequently economic. In the Holy Roman Empire, Jews held the legal status of Kammerknechte (servants of the imperial chamber). They were technically the property of the Emperor, who taxed them heavily in exchange for protection.

The Theory of Fiscal Overfishing:

Recent economic research suggests a correlation between political fragmentation and violence, described as "fiscal overfishing." Where the rights to tax Jewish communities were securely possessed by a single ruler (like the Emperor or a powerful King), that ruler had a strong incentive to protect the Jews to preserve his revenue stream. However, in the fragmented German lands, local rulers, bishops, and city councils often disputed these rights. This contestation meant that no single authority had a secure, long-term interest in the Jewish community's survival. Consequently, the "rents" from Jewish moneylending were contested, making the community vulnerable to predation.10

The massacres provided a mechanism for immediate debt cancellation. In Strasbourg and Basel, documents show that following the burnings, the debts owed to Jewish moneylenders were declared void or the pledges were distributed among the conspirators. Even Emperor Charles IV, ostensibly the protector of the Jews, pragmatically acquiesced. In Nuremberg, he granted the city council permission to destroy the Jewish quarter and construct a church on the site of the synagogue, effectively "selling" the Jews to the mob in exchange for political loyalty.10

1.7 Archaeology of the Pogrom: The Tàrrega Excavations

For centuries, the history of these massacres relied primarily on chronicles. However, recent archaeological work has provided physical evidence of the violence. In 2007, excavations in the Catalan town of Tàrrega identified the medieval Jewish cemetery. Six communal graves were found containing individuals who had suffered violent deaths.13

These remains date to the summer of 1348, corroborating textual reports of an assault on the Jews of Tàrrega during the Black Death. The presence of mass graves indicates the scale of the slaughter and the breakdown of normal burial customs. This bioarcheological evidence serves as a grim testament to the reality of the pogroms, moving the narrative from the abstract realm of historical texts to the physical reality of fractured bones and hurriedly buried bodies.13

Section II: The Early Modern Transition and Precursors

The Black Death was the climax of medieval antisemitism, but it was not without precedent. The infrastructure of blame had been built over previous decades, establishing the neural pathways that society would follow when the plague arrived.

2.1 The Leper Scare of 1321: The Blueprint for Blame

The template for the accusation of well-poisoning was established nearly three decades before the Black Death. In 1321, a hysteria swept through southwestern France accusing lepers of attempting to spread their illness by poisoning water sources. These accusations quickly evolved to include a broader conspiracy: that the plot was initiated by Muslim rulers in Spain and aided by the Jews of France.3

This "Leper Scare" served as a dry run for 1348. It established the idea that a marginalized minority could weaponize disease to destroy the Christian majority. The consequences were severe: both Jews and lepers suffered violent fates, including expulsion, isolation, and execution by fire. This event demonstrates that the "well-poisoning" trope was a flexible narrative device available to be deployed against any "outgroup" during moments of social anxiety.3

2.2 The Absence of England: Expulsion as "Protection"

A notable geographical anomaly in the Black Death persecutions is England. While the plague devastated England as much as the continent, there were no massacres of Jews in 1348/1349. This was not due to English tolerance but rather the total absence of Jews. King Edward I had expelled all Jews from England in 1290.9

This absence highlights a crucial sociological variable: for a scapegoating mechanism to result in violence, the scapegoat must be physically present. In England, the psychological need to blame was likely displaced onto other targets or remained diffuse, whereas in the Rhineland, the visible presence of Jewish communities provided a ready focal point for the population's terror.

2.3 Biowarfare and the Orientalist Imagination (Kaffa to Venice)

The concept of disease as a weapon—central to the well-poisoning accusation—was not entirely a fantasy of the European mind. The Black Death itself arrived in Europe via a biological attack: the Tartar siege of Kaffa in 1346, where the besieging army catapulted plague-infected corpses over the city walls.16

This event, reported by chroniclers like Gabriele de' Mussi, embedded the idea that the plague was a tool of war used by "Eastern" enemies. Since Jews were frequently associated with the East (both theologically and culturally), it was a short cognitive leap for medieval Christians to imagine them as agents of an oriental biological assault. The confession of Agimet explicitly links the poison to Venice and the Mediterranean, reinforcing the idea of a foreign, imported threat.2

Section III: The Nineteenth Century: Cholera, Class, and the "Filthy" Immigrant

The transition from the medieval to the modern era shifted the antisemitic narrative from theology to biology. The 19th century, characterized by rapid urbanization, industrialization, and the birth of germ theory, saw the Jew transformed from a "poisoner of wells" to a "generator of filth."

3.1 The 1832 Pandemic: From Poisoners to Revolutionaries

When cholera first arrived in Western Europe in the 1830s, the medieval trope of poisoning resurfaced. In Paris in 1832, as thousands died, rumors spread that "poisoners" were contaminating food and wine. However, unlike in 1348, the violence in France was less focused on Jews and more on class lines, targeting doctors, the government, and the wealthy.18

This divergence suggests that in the post-Enlightenment West, the "Jew" was no longer the exclusive receptacle for conspiracy. However, the "poisoning" narrative remained a powerful cognitive tool. In 1832, the "poison" was interpreted through the lens of political revolution—a tool of the state to kill the poor—rather than a tool of the Jews to kill Christians. Yet, the underlying structure of "hidden malevolence" remained identical.18

3.2 The Russian Context: Cholera Riots and the Pale of Settlement

In contrast to the West, the Russian Empire maintained a more medieval structure of blame. The "Cholera Riots" of 1831-1832 initially targeted doctors and officials, but as the century progressed, these tensions were increasingly directed at the Jewish Pale of Settlement. The "pogrom," a term that entered the English lexicon after the anti-Jewish riots of 1881-1884, became the standard response to social stress in Russia.20

While the 1881 pogroms were triggered by the assassination of Tsar Alexander II, they were sustained by an environment of economic misery and disease. The Russian peasantry, suffering from poor harvests and industrial downturns, viewed the Jews as exploiters. The government often tacitly encouraged this violence to divert revolutionary energy away from the state. In this context, the Jew was not just a biological threat but a political scapegoat used to stabilize the autocracy.22

3.3 The 1892 Hamburg-New York Axis: Quarantine as Persecution

By the outbreaks of 1892, particularly in port cities like New York and Hamburg, the accusation had shifted. Jews were no longer accused of actively poisoning water, but of being the poison through their alleged lack of hygiene. Public health officials, grappling with the spread of cholera and typhus in overcrowded tenements, frequently scapegoated Jewish immigrants from Eastern Europe.23

In New York in 1892, Jewish immigrants arriving on ships were singled out for harsh quarantines. The "incubation period" of the disease became a political tool to detain Jewish migrants. The press frequently described the Jewish quarter as a breeding ground for pestilence, conflating poverty with biological danger. This was not unique to Jews; Italians and others were also targeted, but the antisemitic trope of the "dirty Jew" gave a specific virulence to the measures against Eastern European migrants.23

Dr. Maurice Fishberg's Defense:

Dr. Maurice Fishberg, a Jewish physician and amateur anthropologist, spent much of his career refuting these claims. He collected data to show that Jewish immigrants were not inherently "inferior" or "diseased." He argued that their health issues were solely the result of poverty, poor sewage, and contaminated water in the Pale of Settlement. Fishberg's work was a desperate attempt to use the tools of modern science to dismantle the racialized pseudoscience being used to justify exclusion.24

3.4 Case Study: The Ottoman East – Izmir 1893 and the Economics of Vulnerability

The pattern of blaming the poor and the "other" was not unique to the Christian West. In the Ottoman city of Izmir during the 1893 cholera epidemic, local authorities identified a direct correlation between overcrowding and disease. This led to the specific targeting of the Jewish poor, whose quarters were seen as the "original source" and disseminators of cholera to the rest of the city.26

The response in Izmir involved the forced removal of Jews to the outskirts of the city and the plundering of their property. This demonstrates that the scapegoating mechanism is not exclusively Christian but is a function of power dynamics where a marginalized group—regardless of the dominant religion—is blamed for biological catastrophe. The "ghost city" phenomenon, where the wealthy fled and left the poor to die, exacerbated the visibility of the Jewish victims, who, lacking resources to flee, were left to bear the brunt of both the disease and the blame.26

3.5 The Diaries of Louis Röhmann: A Jewish Perspective from Berlin

To understand the psychological impact of these epidemics on the Jewish community, the diary of Louis Röhmann, a student in Berlin during the 1837 cholera outbreak, offers a rare primary perspective. Röhmann records the rising fear: "Cholera is still claiming a significant number of victims and there is much fear here, especially amongst rich Jews".27

Röhmann's entries reveal the internal anxiety of the community. He notes that rumors of the disease turned rapidly into reality, and while he feigned indifference ("I am trying to ridicule the whole thing"), his concern for his mother and his adherence to a diet reveal a deep underlying dread. His observation that classmates were leaving Berlin "out of laziness and homesickness" masks the reality of flight from a city where disease and social tension were mounting. This document humanizes the statistics, showing a young Jewish man navigating a world where his community was both a victim of the disease and a target of the fear it engendered.27

Section IV: The Twentieth Century: Typhus, Eugenics, and the Literalized Parasite

The most lethal intersection of antisemitism and disease occurred during the 20th century, where the metaphor of the "parasite" was literalized by the Nazi regime. Typhus, a louse-borne disease associated with war and deprivation, became central to the Nazi justification for the Holocaust.

4.1 The Great Anomaly: The 1918 Influenza Pandemic

A striking finding in the analysis of pandemic scapegoating is the relative absence of antisemitic violence during the 1918 Spanish Flu. Unlike the Black Death or the 19th-century cholera outbreaks, the 1918 flu did not trigger massive pogroms or widespread accusations of Jewish malevolence.28

Why Was 1918 Different?

Several factors contributed to this anomaly:

1. Universality of Suffering: The Spanish Flu killed young, healthy adults of all backgrounds indiscriminately and with terrifying speed. It did not linger in "slums" in the same way cholera or typhus did, making it harder to racialize as a disease of the "filthy other".24

2. War Context: The world was embroiled in WWI. The "enemy" was clearly defined (the Central Powers or the Allies). In the US, Germans were the target of suspicion, not Jews.

3. Jewish Medical Integration: By 1918, Jews were significantly integrated into the medical profession in the US and Germany. Figures like Lawrence Arnstein in San Francisco and Dr. Harry Plotz of the Joint Distribution Committee were visible leaders in the fight against the virus. The JDC was active in relief efforts, positioning Jews as part of the solution rather than the problem.29

4. Community Management: Jewish leaders actively worked to prevent blame. For example, the Rabbinic courts in New York suspended the laws of shiva (mourning) to prevent overcrowding, demonstrating publicly that the community was adhering to hygiene protocols. This proactive management deflected potential accusations.25

Black Weddings:

Within the Jewish community, the response was spiritual. Rituals like the "Black Wedding" (shvartze chasene) were performed, where two orphans were married in a cemetery to beseech the spirits and God to end the plague. This internal focus on spiritual remediation contrasts sharply with the external projection of blame seen in other eras.31

4.2 The Racialization of Disease: WWI Border Controls and "Delousing"

While the flu did not trigger pogroms, the era of WWI saw the institutionalization of medical antisemitism. German fears of "Eastern" diseases (typhus and cholera) became inextricable from their fear of the Ostjuden (Eastern Jews). Border controls established in 1918 specifically barred Jewish migrant workers, categorizing them as health risks.

The "delousing" stations set up on the eastern border were crucial precursors to the Holocaust. They trained officials to view Jewish bodies as vectors of contamination that required chemical intervention. The conflation of the Jew with the louse—the carrier of typhus—began here, transforming a medical procedure into a tool of racial exclusion.32

4.3 Nazi Epidemiology: Typhus as a Weapon of Genocide

Under the Nazi regime, this medicalized antisemitism became state policy. German medical officials in occupied Poland (1939-1945) argued that Jews were natural carriers of typhus. This belief was used to justify the creation of ghettos, arguing that to protect the "Aryan" population from infection, Jews had to be walled off.32

The Self-Fulfilling Prophecy:

The conditions created within the ghettos—extreme overcrowding, starvation, lack of soap, and collapsing sanitation—were precisely the conditions required for typhus to flourish. When epidemics inevitably broke out (such as in the Warsaw Ghetto in 1941), Nazi propaganda cited the disease as proof of their original thesis: that Jews were biologically dangerous. The Nazis created the plague and then blamed the victims for dying of it.33

4.4 Propaganda of the Body: "Jews are Lice" and the Warsaw Ghetto

This narrative was disseminated through visual propaganda. The famous 1941 poster in occupied Poland, declaring "Jews are lice; they cause typhus" (Żydzi – wszy – tyfus plamisty), explicitly collapsed the distinction between the vector (the louse) and the victim (the Jew).35

The metaphor of the parasite had evolved. In the 19th century, antisemites spoke of Jews as mistletoe or cuckoos—parasites that drain resources. By the 1940s, the metaphor was microbiological: the Jew was a bacillus. German doctors played a complicit role, publishing essays claiming that the "low cultural level" and "uncleanliness" of the Jews were to blame for the epidemics. This "racialization of disease" was a key step in the psychological conditioning of the German populace; if Jews were a biological threat, their elimination was not murder, but sanitation.32

Section V: The Digital Pandemic: COVID-19 and the Resurrection of Libel

The COVID-19 pandemic saw a resurgence of antisemitic conspiracy theories that rivaled the medieval period in their virulence, amplified by the algorithmic architecture of the internet. The Anti-Defamation League and other monitoring bodies reported massive spikes in antisemitic content linking Jews to the virus.37

5.1 The New "Well Poisoning": Bioweapons and 5G Conspiracies

Digital antisemitism during COVID-19 represented a remixing of medieval and 20th-century tropes. Claims circulated that Jews or Israel engineered the virus as a bioweapon to sell vaccines or thin the non-Jewish population. This is structurally identical to the 1348 accusation of poisoning wells, merely substituting "wells" with "laboratories".38

The "5G" conspiracy theory, which claimed that cellular towers were spreading the virus, often integrated antisemitic elements, claiming that the technology was controlled by "Zionist" interests to sterilize or control the population. This merges technophobia with the ancient fear of Jewish control over invisible forces.41

5.2 QAnon, Adrenochrome, and the Modern Blood Libel

The QAnon conspiracy theory, which gained massive traction during the pandemic lockdowns, acted as a "big tent" for antisemitism. Its central tenet—that a global elite harvests "adrenochrome" from the blood of tortured children—is a direct modernization of the medieval Blood Libel (the accusation that Jews use Christian blood for ritual purposes).42

By stripping the specific word "Jew" and replacing it with "Globalist," "Cabal," or "Elite," QAnon allowed these antisemitic tropes to circulate among people who might reject explicit neo-Nazism. This "dog whistle" politics allowed the conspiracy to spread via social media algorithms that might otherwise flag explicit hate speech. The narrative of a hidden, blood-drinking elite controlling world events is the Protocols of the Elders of Zion repackaged for the Instagram generation.43

5.3 The "Holocough": Weaponizing Sickness in the Far Right

Far-right extremists on platforms like Telegram engaged in what they termed the "Holocough." They encouraged followers who contracted COVID-19 to deliberately spread the virus to Jewish communities and synagogues. This represents a horrifying inversion of the "well-poisoning" accusation: instead of falsely accusing Jews of spreading disease, neo-Nazis actively sought to use their own infected bodies as biological weapons against Jews.45

5.4 Algorithmic Hate: Social Media as the New Vector

Social media platforms facilitated this spread through recommendation algorithms that prioritize engagement over accuracy. Research indicates that exposure to conspiracy theories on platforms like Facebook and Twitter (now X) increased antisemitic attitudes. The "echo chamber" effect allowed isolated antisemites to connect, forming a global network of hate that transcended national borders. The anonymity of the internet, combined with the "filter bubble," created a breeding ground for radicalization where medieval myths could be presented as "secret knowledge".46

Section VI: Sociological and Psychological Mechanisms of Blame

To understand why Jews are consistently blamed for disasters, we must look beyond history to sociology and evolutionary psychology. The persistence of these accusations suggests they serve a psychological function for the accuser.

6.1 The Parasite Stress Theory: Pathogen Avoidance and Xenophobia

Evolutionary psychology proposes the existence of a "Behavioral Immune System"—a set of cognitive mechanisms designed to detect and avoid infectious disease. Research suggests that when the threat of disease is high (high "parasite stress"), humans become more xenophobic, conformist, and ethnocentric.49

Because Jews have historically maintained distinct customs (dietary laws, dress, language), they trigger the hyper-active "other" detection of a stressed population. The psychological response to a pathogen (disgust, avoidance) is socially projected onto the outgroup. This explains why antisemitic rhetoric so often relies on the language of hygiene and filth ("vermin," "parasite," "virus"). The brain's pathogen-avoidance hardware is hijacked to fuel social prejudice.51

6.2 Terror Management Theory: Mortality Salience and the Other

Terror Management Theory (TMT) posits that humans embrace cultural worldviews (like religion or nationalism) to buffer the terrifying awareness of their own mortality. Pandemics bring "mortality salience" to the forefront. When people are reminded of death, they cling more tightly to their ingroup and react with hostility toward outgroups who threaten their worldview.53

Blaming Jews serves a dual function under TMT:

1. Restores Control: A virus is invisible and random; a conspiracy is structured and defeatable. If the plague is caused by a "poisoner," the poisoner can be killed, and the threat removed. It imposes a narrative of cause-and-effect on chaos.54

2. Validates the Ingroup: By defining the "Other" as evil/diseased, the ingroup feels morally and physically superior.56

6.3 The Behavioral Immune System and the Aesthetics of Disgust

Antisemitism is frequently characterized by the emotion of disgust. Historical texts, such as the poem by Gervase Markham (1600s), describe Jews in visceral terms involving slime, spit, and feces. This "affective charge" utilizes the biological disgust response to create a moral aversion. During pandemics, this sensitivity is heightened. The mask-wearing or isolation of the Jew is not just a social act but a biological reflex of the antisemite to avoid "contamination".52

6.4 The Economics of Scapegoating: Complementarities vs. Competition

Finally, the economic dimension cannot be ignored. As seen in the "fiscal overfishing" of the 14th century, violence is often a rational (if morally abhorrent) choice for rulers. However, economic theory also suggests that when a minority plays a non-substitutable economic role (e.g., specific banking functions or medical expertise), they are less likely to be persecuted. This may explain the 1918 anomaly: the Jewish contribution to the medical response made them "complements" to the majority rather than competitors or threats.58

Conclusion

The history of pandemics is inextricably bound to the history of antisemitism. The data reveals a persistent pattern: whenever a society faces a biological threat it cannot control or understand, it projects the source of that threat onto the Jewish minority.

This projection has evolved from the theological to the biological, and finally to the digital.

• In the 14th century, the Jew was the Anti-Christ, poisoning the spiritual and physical waters of Europe.

• In the 19th and 20th centuries, the Jew was the Anti-Human, a biological parasite threatening the racial purity of the nation.

• In the 21st century, the Jew is the Anti-Citizen, a globalist conspirator manipulating world health for domination.

While the specific accusations change, the underlying structure remains identical: the Jew is cast as the internal enemy who weaponizes the crisis to destroy the majority. This is not merely a result of ignorance but a defense mechanism rooted in economic opportunism (debt cancellation), political power consolidation (Nazi ideology), and deep-seated psychological responses to mortality and disgust.

The only significant deviation from this pattern—the 1918 Influenza Pandemic—suggests that integration and visible participation in the solution can mitigate, though not entirely eliminate, this impulse. However, the resurgence of these tropes during COVID-19 warns that as long as societies face existential dread, the reflex to blame the "Other" remains a dormant virus, waiting for the next crisis to re-emerge. The well is no longer poisoned with spiders and frogs; it is poisoned with pixels and algorithms, but the intent—to identify, isolate, and destroy the scapegoat—remains unchanged.
