The Tribunal of the Holy Office of the Inquisition, commonly known as the Spanish Inquisition, was a tribunal established in 1480 by Catholic Monarchs, Ferdinand II of Aragon and Isabella I of Castile. It was intended to maintain Catholic orthodoxy in their kingdoms, ordering Jews and Muslims to convert or leave. It continued for nearly four hundred years.
The first auto-da-fé was held in Seville on February 6, 1481: six people were burned alive. From there, the Inquisition grew rapidly.
