The Crusades and the Inquisition: What Really Happened?
The Crusades and the Inquisition had real causes and smaller numbers than the myths, but they included real crimes, and the Church has repented of using violence for the faith.

What this lesson teaches
- The Crusades began in 1095 as a response to real conquests, but crusaders committed grave crimes.
- The Spanish Inquisition was largely royal and executed an estimated 3,000 to 5,000 people over centuries.
- Most witch trials were secular, and Galileo was confined, not tortured; the Church later admitted the error.
- In 2000 the Church publicly asked forgiveness for violence used in the service of the faith.
