Zurich massacre

SOLVED1624Zurich, Switzerland3 SOURCESUPDATED JUL 2026
Illustrative

In 1349, the Jewish community of Zurich, Switzerland was massacred amid the wave of antisemitic persecution that swept Europe during the Black Death, when Jewish communities were widely and falsely blamed for spreading the plague by poisoning wells.

The violence in Zurich was preceded by a false accusation of ritual murder after a young boy was found dead. Such "blood libel" accusations were a recurring antisemitic myth of the period; some modern historians doubt this episode occurred at all, as it is not recorded in any contemporary chronicle and first appears in writing roughly two centuries later. Jews accused over the child's death were put to death, and others were banished.

Soon afterward, the Zurich Jewish community was accused of poisoning wells, and the city council ordered its members burned to death. Sources differ on the exact date in February 1349. Some who fled to nearby Kyburg Castle were killed there as well. The Zurich community is estimated to have numbered around 400 people, most of whom were killed.

In the aftermath, the property of those killed was seized — Zurich's mayor, Rudolf Brun, is named as taking one such house — while surviving women and children were allowed to keep property but were banished, and debts owed to Jews were cancelled. Despite the massacre, a Jewish community returned to Zurich by 1352. Further expulsion orders followed in the fifteenth century, and Jews were ultimately expelled from Zurich in 1624.
