The greater the indebtedness of the Christians to the Jews, the more inimical became their attitude. As a result of this state of affairs, the governor of the islands forbade (1390) all Jews to carry weapons, even in their own quarter, or to leave their homes two hours after sunset without carrying a light. After the outbreaks in Valencia and Barcelona (1391), the governor had to interfere for the safety of the Jews' quarter in Palma de Mallorca.

On August 24, 1391, the long-dreaded calamity fell upon the community of Majorca. Jewish homes were sacked; and even the houses of Christians sheltering Jews in concealment were not spared.

About 300 Jews were put to death, 800 saved themselves in the royal castle, and the rest underwent baptism.

When Queen Violante was informed of the outrage, she condemned the inhabitants of the islands to pay a fine of 150,000 florins (or, according to some authorities, 104,000 florins).

A year later (1392), however, Juan I granted full amnesty to all who had practised violence against the Jews or "the Calle," because they had done it for the welfare of king and state; and he further declared all debts of the Christians to the Jews to be null and void.
