In Spain what was the purpose of the Inquisition in the 16th century?

The purpose of the Inquisition in Spain during the 16th century was primarily to maintain Catholic orthodoxy and consolidate religious uniformity following the Reconquista. It aimed to identify and punish heresy, particularly among converted Jews and Muslims, who were suspected of secretly practicing their former religions. The Inquisition also served to strengthen the power of the monarchy by enforcing loyalty to the Catholic Church and the Spanish crown. Ultimately, it was a tool for social and religious control during a time of significant political and cultural change.
