25 July 1360 – 11 Av 5120
Anti-Jewish riots broke out in Wrocław (known in German as Breslau), today in Poland, after a fire destroyed large parts of the city. This was the second time Jews were blamed for a conflagration; eleven years earlier, under similar circumstances, sixty Jews were killed and Jewish property, including two synagogues and a cemetery, was seized by the city and its ruler. On this occasion, a number of Jews were murdered, and the rest expelled. Jews were seen as natural scapegoats for all kinds of natural disasters in the Middle Ages, and Jew-killings were a common side-result of fires, plague, floods and famine.
