The Inquisition had been created in the twelfth century by Pope Lucius III to fight heresy in the south of what is now France and was constituted in a number of European kingdoms. The Catholic Monarchs decided to introduce the Inquisition to Castile, and requested the Pope's assent. On 1 November 1478, Pope Sixtus IV published the papal bull "Exigit Sinceras Devotionis Affectus", by which the Inquisition was established in the Kingdom of Castile; it was later extended to all of Spain. The bull gave the monarchs exclusive authority to name the inquisitors.
