The Inquisition is a group of institutions within the judicial system of the Roman Catholic Church whose aim was to combat heresy. It started in 12th-century France to combat religious sectarianism, in particular the Cathars and the Waldensians. Other groups which were investigated later include the Spiritual Franciscans, the Husites (followers of Jan Hus) and Beguines. Beginning in the 1250s, inquisitors were generally chosen from members of the Dominican Order, to replace the earlier practice of using local clergy as judges. The term Medieval Inquisition covers these courts up through the 14th century.
