Jansenism was a Catholic theological movement, primarily in France, that emphasized original sin, human depravity, the necessity of divine grace, and predestination. The movement originated from the posthumously published work of the Dutch theologian Cornelius Jansen, who died in 1638. It was first popularized by Jansen's friend Abbot Jean Duvergier de Hauranne, of Saint-Cyran-en-Brenne Abbey, and after Duvergier's death in 1643, was led by Antoine Arnauld. Through the 17th and into the 18th centuries, Jansenism was a distinct movement within the Catholic Church. The theological centre of the movement was the convent of Port-Royal Abbey, Paris, which was a haven for writers including Duvergier, Arnauld, Pierre Nicole, Blaise Pascal, and Jean Racine.
