A priest, hit with a few grains of sand or pebbles by small Jewish boys playing in the street, became insulted and insisted that the Jewish community purposely plotted against him. The priests followers beat up the boys whose parents arrived to defend them. A mob was then incited to attack the ghetto. Thousands were slaughtered, the synagogue and the cemetery were destroyed, and homes were pillaged. King Wenceslaus insisted that the responsibility rested with the Jews for venturing outside during Holy Week.
