Through the inquistion, those who were believed to have acted contrary to the doctrines of the Catholic Church were condemned as misbelievers. Then, they were first excommunicated and later transferred to the courts to ‘leave the world’. The method for ‘leaving the world’ included various forms of torture such as auto da-fe and drownings. The inquisition was revived and reinvented in the fight against the Protestants in the 16th century. The Spanish Inquisition also tested the sincerity of Christian converts. As a result, thousands of Jews and Muslims were burned to death.
