On March 10, 1762 Jean Calas was tortured and executed for allegedly murdering his son Marc-Antoine. Although Jean was the only member of the family executed, his wife, servant, son Paul, and friend M. Gaubert Lavaysse were also implicated in the murder. The Calas affair came to Voltaire’s attention because it appeared to be a case of religious fanaticism.


Through a series of authentic and potentially fictional letters, The Calas Affair traces the events leading up to and following the death of Marc-Antoine.But it’s the following Treatise on Tolerance that is arguably more important than the précis of the affair. Here, Voltaire makes a case for religious tolerance.
