How did catholic reform turn into the catholic reformation?

Catholic reform began as a response to the challenges posed by the Protestant Reformation, focusing on addressing corruption within the Church and reaffirming Catholic doctrine. Over time, this reform movement evolved into the Catholic Reformation, characterized by a more organized effort to revitalize the Church through the Council of Trent (1545-1563), which clarified Catholic teachings, reformed clerical practices, and emphasized the importance of sacraments. This transformation reflected a proactive stance by the Catholic Church to reclaim its influence and engage with modernity, ultimately leading to a renewed spiritual vigor and the establishment of new religious orders.
