The Cult of Reason (French: Culte de la Raison) was a creed based on atheism devised during the French Revolution by Jacques Hébert, Pierre Gaspard Chaumette and their supporters. It was stopped by Maximilien Robespierre, a Deist, who instituted the Cult of the Supreme Being. Both cults were the outcome of the "de-Christianization" of French society during the Revolution and part of the Reign of Terror.
