The Catholic Reformation, also known as the Counter-Reformation, was a movement within the Catholic Church in the 16th and 17th centuries aimed at addressing issues raised by the Protestant Reformation. It sought to reform church practices, clarify doctrine, and reaffirm the authority of the pope, ultimately leading to a revitalization of the Catholic faith. The movement included the establishment of new religious orders, the Council of Trent, and efforts to combat Protestantism and spread Catholicism globally.
