http://en.wikipedia.org/wiki/Spanish_Inquisition
From the link:
Various motives have been proposed for the monarchs’ decision to found the Inquisition such as increasing political authority, weakening opposition, suppressing conversos, profiting from confiscation of the property of convicted heretics, reducing social tensions, and protecting the kingdom from the danger of a fifth column.
Which worked, sort of.
Spain didn't have a devastating religious war, like Germany, France and England, among others.
