Background and detail

Religious Context. Jean Calas was a Protestant living in an officially Catholic society in Toulouse. His religious status as a Huguenot became central to the accusations against him, with Voltaire later citing the case as an example of the Catholic Church's severity and the parlement's intolerance.

Trial and Sentence. Following the death of his son Marc-Antoine in October 1761, Calas was tried and judicially tortured. On 9 March 1762, the court sentenced him to be broken on the wheel. He was executed on 10 March 1762, despite his continued protestations of innocence.

Exoneration and Legacy. Doubts about Calas's guilt were raised by opponents of the Catholic Church. Voltaire's efforts led King Louis XV to annul the sentence in 1764. The case damaged the reputation of the Toulouse parlement and was used by Voltaire in his 1763 Treatise on Tolerance.
