The Radical Reformation represented a response to perceived corruption both in the Catholic Church and in the expanding Magisterial Protestant movement led by Martin Luther and many others. Beginning in Germany and Switzerland in the 16th century, the Radical Reformation gave birth to many radical Protestant groups throughout Europe. The term covers radical reformers like Thomas Müntzer and Andreas Karlstadt, the Zwickau prophets, and Anabaptist groups like the Hutterites and the Mennonites. In Germany, Switzerland and Austria, a majority sympathized with the Radical Reformation despite intense persecution. Although the surviving proportion of the European population that rebelled against Catholic, Lutheran and Reformed Churches was small, Radical Reformers wrote profusely, and the literature on the Radical Reformation is disproportionately large, partly as a result of the proliferation of the Radical Reformation teachings in the United States. Some early forms of the Radical Reformation were millenarian, focusing on the imminent end of the world. This was particularly notable in the rule of John of Leiden over the city of Münster in 1535, which was ultimately crushed by the combined forces of the Catholic Bishop of Münster and the Lutheran Landgrave of Hesse. After the Munster rebellion, the small group of the Batenburgers continued to adhere to militant Anabaptist beliefs. Non-violent Anabaptist groups also had millenarian beliefs. The early Anabaptists believed that their reformation must purify both theology and the lives of Christians, especially their political and social relationships. Therefore, the church should not be supported by the state, neither by tithes and taxes, nor by the use of the sword; Christianity was a matter of individual conviction, which could not be forced on anyone, but rather required a personal decision for it. Many groups were influenced by Biblical literalism (like the Swiss Brethren), spiritualism (like the south German Anabaptists) and mainly absolute pacifism (like the Swiss Brethren, the Hutterites and the Mennonites from northern Germany and the Netherlands).
