Abb Augustin Barruel (October 2, 1741 - October 5, 1820) was a French Jesuit priest. He is now mostly known for documenting the conspiracy theory involving the Bavarian Illuminati and the Jacobins in his book Memoirs Illustrating the History of Jacobinism (original title M moires pour servir l'Histoire du Jacobinisme) published in 1797. In short, Barruel wrote that the French Revolution was planned and executed by the secret societies. Augustin Barruel was born at Villeneuve de Berg (Ardeche). He entered the Society of Jesus, commonly known as the Jesuits in 1756 and taught grammar at Toulouse in 1762. The storm against the Jesuits in France drove him from his country and he was occupied in college work in Moravia and Bohemia until the suppression of the order in 1773. He then returned to France and his first literary work appeared in 1774: Ode sur le glorieux avenement de Louis Auguste au trone. That same year he became a collaborator of the Ann e litt raire, edited by Fr ron. His first important work was Les Helveiennes, ou Lettres Provinciales philosophiques, published in 1781.
