The document provides background information on the Spanish Inquisition. It occurred from the 15th to 19th centuries as a way for the Catholic Church and Spanish monarchs to find and punish heretics. Early on, non-Catholics were given a choice to convert or leave Spain. Those who did not comply were tortured and sometimes killed. The Inquisition established procedures for accusing, detaining, trying suspects through torture, and sentencing them. Notable Grand Inquisitor Torquemada was responsible for forcing hundreds of thousands of Jews and heretics out of Spain through brutal means.
