Of the despised classes the Mudéjares, as such, soon disappeared, despite their great numbers at the time of the conquest. Upon conversion to Christianity or emancipation from slavery they mixed with the lower classes of the Christians, and were completely absorbed. The history of the Jews was almost identical with that of their race in the peninsula, but was involved with the peculiar social problems of Majorca apart from race and religion. The kings collected heavy tributes from them, but protected them, allowing them the free exercise of their business and the practice of their faith, exempting them from all taxation (even municipal) except the royal tributes, aiding them in the collection of debts, and facilitating the entry of Jews and Marranos into Majorca. Numerous attacks were made on them in the fourteenth century, culminating in the sack of the Jewish quarter of the capital in 1391 (the year which was so disastrous to the Jews in other parts of Spain), when some three hundred men and women were killed. In addition to the usual animosities against them because of their religion and the incitement of debtors this attack was in part an outgrowth of the struggle of the rural classes against the landlords, to whom the sack of the Jewish quarter was a severe financial blow, since much of their wealth depended on their relations with the Jews, with whom also they were wont to deposit their jewels. The rioters were able to obtain decrees from the royal governor-general extinguishing debts and interest due to the Jews, confirming the title of those who had taken part in the attack to the money and jewelry they had stolen, pardoning all offences committed, and ordering an immediate conversion of the Jews. The general conversion took place at once, but had to be repeated in 1435. [Sidenote: The municipal form of Majorcan government.]
