The alumbrados (Spanish pronunciation: [alumˈbɾaðos], Illuminated) was a term used to loosely describe practitioners of a mystical form of Christianity in Spain during the 15th-16th centuries. Some alumbrados were only mildly heterodox, but others held views that were clearly heretical, according to the contemporary rulers. Consequently, they were firmly repressed and became some of the early victims of the Spanish Inquisition.
