The History of Spanish Inquisition

This is one of the best-known works by the American historian Henry Charles Lea. The Spanish Inquisition (officially known as the 'Tribunal of the Holy Office of the Inquisition') was established in 1478 by Catholic Monarchs Ferdinand II of Aragon and Isabella I of Castile. It was intended to maintain Catholic orthodoxy in their kingdoms and to replace the Medieval Inquisition, which was under Papal control. It became the most substantive of the three different manifestations of the wider Catholic Inquisition along with the Roman Inquisition and Portuguese Inquisition. The Inquisition was originally intended primarily to identify heretics among those who converted from Judaism and Islam to Catholicism. The regulation of the faith of newly converted Catholics was intensified after the royal decrees issued in 1492 and 1502 ordering Muslims and Jews to convert to Catholicism or leave Castile. The Inquisition was not definitively abolished until 1834, during the reign of Isabella II, after a period of declining influence in the preceding century. The Spanish Inquisition is often cited in popular literature and history as an example of religious intolerance and repression.
