The
Inquisition was officially established to root out heresy, particularly among
conversos (Jews and Muslims who had converted to Christianity but were suspected of secretly practicing their former faiths). There was a growing concern that these groups threatened the status quo. From that point, Spain became a political melange of different powers and territories, each with its own policies regarding the status of Jews and Muslims. By the 13th century almost all of modern Spain was under Christian rule.
Ferdinand III of Castile boasted of being the king of three religions. This tolerance, however, did not last long. In the 14th century, Dominican and Franciscan priests called on Christians to expel the Jews from Spain, blaming Jews for social problems and stirring the Christian majority to destroy synagogues, burn Jews alive, and impose forced conversion. Jews would be forced to attend sermons and have Christian preachers outline what the Christians viewed as the errors of their ways. New laws segregated the Jewish population and limited the occupations that were still open to them, with the ultimate goal of conversion. More than 100,000 Jews converted. Once converted, these New Christians joined the "conversos" class, who were afforded the legal and social privileges of a full Christian in society. Many New Christians took advantage of their elevation in status and embraced Christian privileges. After a few generations, the converted Jews identified as nothing more or less than "regular" Christians, and Spain was almost uniformly Christian. This uniformity brought with it new sources of anxiety. "The mistrust of the Jew as an outsider gave way to an even more alarming fear of the converso as an insider". The differences between religious classes had formerly been very clear. Laws and customs codified Christian dominance in Spain. Once the Jews converted, however, many Christian Spaniards believed that they no longer knew whom they could trust and who could possibly be a treacherous heretic at heart. In an attempt to assuage these fears,
Limpieza de sangre (Purity of Blood) laws were put in place that traced the bloodline of Christians New and Old to see if they had Jewish ancestry. In doing so, Spain divided its Christian class along ethnic and religious lines, "othering" those with Jewish blood much as it had prior to conversion. Influential Christians believed that there was something different in the essence and soul of the person that could not be cured by religious conversion. On 1 November 1478,
Ferdinand II of Aragon and
Isabella I of Castile received permission from
Pope Sixtus IV to name inquisitors throughout their domains in order to protect Catholicism as the one true Christian faith. The decree originally applied to the
Crown of Castile—the domain of Isabella—but in 1483 Ferdinand extended it to his domain of the
Crown of Aragon.
Autos de fé became quite popular throughout the Spanish realm, competing with
bullfights for the public's attention and attended by royalty. Though Ferdinand's action met with occasional resistance and resulted in the assassination of the inquisitor
Pedro de Arbués by converted Jews in 1485, between 1487 and 1505 the processing and trying of more than 1,000 heretics was recorded by the Barcelona chapter, of whom only 25 were ultimately absolved. , illustration from 1870 Once granted permission from the Pope to conduct inquisitions, the monarchs began establishing permanent trials and developing bureaucracies to carry out investigations in most of the cities and communities in their empire. The first
Iberian auto de fé took place in
Seville in 1481: the six accused were found guilty and executed. Later,
Franciscan missionaries brought the
Inquisition to the
New World. The Portuguese Inquisition was established in 1536 and lasted officially until 1821. Its influence was much weakened by the late 18th century under the government of the
Marquês de Pombal.
Autos de fé also took place in
Goa,
New Spain, the
State of Brazil, and the
Viceroyalty of Peru.{{cite book == Scale and numbers ==
