The Spanish Inquisition was a tribunal started in 1478 in Spain. It was started by Ferdinand II of Aragon and Isabella I of Castile, with the assistance of Torquemada. During the Spanish Inquisition many people were burnt in front of crowds in the streets. In practice, the Spanish Inquisition served to consolidate power in the monarchy of the newly unified Spanish kingdom, but it achieved that end through infamously brutal methods.
The rulers of Spain asked the Pope to start the Inquisition to catch Jews who pretended to be Christians. In 1492 they commanded all Jews and Muslims to leave Spain. Many left, but many stayed and said they were Christians. The Inquisition became busy deciding which ones were lying. When Protestants appeared, the Inquisition said they were just pretending to be Christians. Most trials ended with the defendant simply giving up his beliefs and being let go. The Inquisition became less active in later years and was completely abolished in 1834.
