The Hungarian Reformation was a religious movement in the 16th century that sought to reform the Catholic Church in Hungary. Influenced by the broader Protestant Reformation in Europe, it led to the rise of Lutheranism and Calvinism among Hungarian communities. Key figures, such as János Zsigmond, supported these new ideas, promoting religious change and the translation of the Bible into Hungarian. The movement faced significant opposition from the Catholic Church and the Habsburg rulers, who sought to maintain their influence. Despite this resistance, the Reformation had a lasting impact on Hungarian society, contributing to the development of a distinct Hungarian identity and the establishment of various Protestant denominations in the region.
