Pope Sixtus IV, authorizes on February 11, 1482, the appointment of Tomás de Torquemada as one of seven chief inquisitors in Spain. He became the Grand Inquisitor c. August 15, 1483 for Castile and Aragon.
On October 17, 1483, Torquemada's authority was extended to include Aragon, Catalonia, Majorca and Valencia effectively making him the Inquisitor General for all of Spain. Torquemada served as the Grand Inquisitor until his death on September 16, 1498. It is believed that the Spanish Inquisition was responsible for over 30,000 executions. The institution was finally shut down on July 15, 1834, during a period of liberal reform in Spain. The last person executed by the Inquisition was Cayetano Ripoll, a schoolmaster hanged in 1826.
