The term "Jansenist" refers to followers of Jansenism, a theological movement within Catholicism that emerged in the 17th century. It was founded by Cornelius Jansen, who emphasized the importance of divine grace and the limitations of human free will. Jansenists believed that only a select few could achieve salvation, which led to significant theological debates within the Church. Jansenism was often in conflict with the Jesuits, who held opposing views on grace and free will. The movement gained traction in France, particularly in the Port-Royal Abbey, but faced condemnation from the Catholic Church. Ultimately, Jansenism declined in influence by the 18th century.
