Kingdom of Aragon
The internal conflicts, the war with Castile and above all the Black Death and other epidemics in the 14th century produced an important decrease in the population of the kingdom. In 1492 the Catholic Monarchs decreed the conversion or expulsion of the Jews. In 1495 a census was taken, the fogaje of 1495, which revealed a total of 51 540 fires in the kingdom, or about 200 000 inhabitants. Muslims then made up 11% of the total population. The most populated city, Zaragoza, had less than 20,000 inhabitants.
