Jean Calas was a merchant living in Toulouse, Languedoc, France, who was tried, judicially tortured, and executed for the murder of his son, despite his protestations of innocence. Calas was a Protestant in an officially Catholic society. Doubts about his guilt were raised by opponents of the Catholic Church and he was exonerated in 1764. In France, he became a symbolic victim of religious intolerance, along with François-Jean de la Barre and Pierre-Paul Sirven.
