The Swiss Reformation was a religious movement in the 16th century that aimed to reform the practices and beliefs of the Roman Catholic Church in Switzerland. Key figures included Ulrich Zwingli in Zurich and John Calvin in Geneva, who promoted ideas such as the authority of Scripture and the rejection of certain church traditions. This movement led to the establishment of Protestantism in Switzerland, resulting in significant changes in worship, governance, and community life. The Swiss Reformation also influenced other regions in Europe, contributing to the broader Reformation movement that challenged the Catholic Church's authority.
