You have probably heard of the Spanish Inquisition, even if only from a certain Monty Python sketch.  The truth about why it was started and for what purpose will probably surprise you.  In this episode we take a close look at the episodes in Spanish history that prepared the way for the Inquisition.  We also examine how it operated, what forms of torture were used, and who it targeted.  Why did the Pope try to stop it?  What was an auto da fe?  What did it have in common with totalitarian surveillance states?  The villains and victims in this history are almost certainly not who you would expect.
