A Jewish boy preparing for baptism was persuaded by his parents to repent. As a result, local Christians attacked the Jews who fought back and a number of townspeople were killed. As the attack intensified and seeing no other option, the Jews set fire to their houses. The fire spread to the rest of the community, destroying nearly half the city. One hundred and eighty Jews died, and twenty-four agreed to be baptized. Conrad IV, the emperor's son, granted amnesty to the Christian residents.
