In short
Starting in 1347, the bubonic plague killed roughly 75 million people across Europe over the next few years, wiping out entire towns and destabilizing the continent's economy and social order. Jewish communities became scapegoats, blamed for spreading the disease despite having no connection to it; from 1348 to 1351, mobs massacred thousands in cities including Strasbourg, Basel, Frankfurt, and Barcelona. The violence revealed how quickly societies fracture under catastrophic stress, and demonstrated the lethal power of medical ignorance paired with existing prejudice.
How it unfolded.
The five-minute version
What actually happened.
The persecution of Jews during the Black Death consisted of a series of violent mass attacks and massacres. Jewish communities were often blamed for outbreaks of the Black Death in Europe. From 1348 to 1351, acts of violence were committed in Toulon, Barcelona, Erfurt, Basel, Frankfurt, Strasbourg and elsewhere. The persecutions led to a large migration of Jews to Jagiellonian Poland and the Grand Duchy of Lithuania. There are very few Jewish sources on Jewish massacres during the Plague.

Timeline
How it actually unfolded.
Black Death arrives in Europe
Genoese merchant ships fleeing Kaffa in the Crimea reach Messina, Sicily, carrying plague-infected rats and fleas. Port authorities initially attempt quarantine but fail to contain the disease.
Plague spreads to mainland Europe
The disease reaches southern France and spreads rapidly through Mediterranean ports. By mid-year, major cities including Florence, Venice, and Avignon report mass deaths.
First Jewish massacres begin
Communities in Toulon and elsewhere are blamed for the plague and attacked. Medical understanding does not exist; scapegoating becomes systematic across Europe.
Strasbourg massacre
Approximately 2,000 Jewish residents are burned alive in a massive pogrom. The city's government-sanctioned violence becomes one of the deadliest single incidents of the persecution wave.
Basel massacre
Jewish communities are burned in their homes. Survivors are expelled; the city remains largely depopulated of Jews for decades.
Flagellant movement peaks
Religious movements emerge claiming penance can stop the plague. Some groups turn violent against Jewish communities, intensifying persecution.
Persecution wave begins to subside
As plague mortality decreases in some regions, organized pogroms become less frequent, though Jewish communities remain decimated and expelled from major European cities.
First wave of Black Death subsides
European mortality rates stabilize; the initial catastrophic phase ends, though the plague will return in recurring waves throughout the next centuries.

The world it landed in
What was on the radio, the screen, and everyone's mind.
Same week, elsewhere
The Black Death era lacked recorded popular music, film, or television. Cultural output consisted of plague-related religious art, mystery plays performed orally in towns, and illuminated manuscripts. Anti-Jewish violence was often framed through Christian theological discourse about sin and divine punishment, reflected in surviving chronicles by Froissart and others.

Impact
What followed.
The Black Death killed an estimated 30–60% of Europe's population between 1347 and 1353, triggering economic collapse, labor shortages that paradoxically strengthened peasants' bargaining power, and a wave of pogroms against Jewish communities. The pandemic reshaped feudalism, accelerated the end of serfdom in Western Europe, and left psychological scars that persisted for centuries. It also demonstrated how medical ignorance and scapegoating could turn a natural disaster into a social catastrophe.
Threads pulled by this event
- 1349
Strasbourg massacre
Over 2,000 Jews were burned alive in the Strasbourg ghetto on February 14, blamed for poisoning wells. The city council authorized the killings despite lacking any evidence.
- 1349
Rise of flagellant movements
Penitential flagellant processions spread across Europe claiming to prevent plague. Some flagellant groups also participated in or encouraged anti-Jewish violence, framing it as divine will.
- 1350
Expulsion from major cities
Surviving Jewish communities were expelled from Frankfurt, Basel, and other German cities following accusations of well-poisoning. Many fled eastward toward Poland and Lithuania.
- 1351
Labor shortage crisis
The simultaneous death toll from plague and pogrom-related killings created severe labor shortages across Europe. Surviving workers gained bargaining power, leading to wage increases and social unrest among landowners.
- 1352
Shift in medical understanding
European physicians began questioning miasma theory as the sole explanation for plague spread. Jewish physicians' survival in some communities eventually contributed to new theories about disease transmission.
