Protestant Reformation

During the Middle Ages, the Catholic Church became increasingly corrupt, leading to the Protestant Reformation. Martin Luther's Ninety-Five Theses criticized the church's sale of indulgences and called for reforms such as banning indulgences, simplifying mass, and translating the Bible into German. Despite being excommunicated, Luther's ideas gained support in Germany, fostering nationalism and leading to the creation of Lutheranism.
