The relationship of the Zwickau Prophets to the Anabaptist movement has been variously interpreted. They have been viewed as a precursory foundation of Anabaptism before the rise of the Swiss Brethren in 1525, as unrelated to the movement except for the influence on Thomas Müntzer and as being a dual foundation with the Swiss Brethren to form a composite movement of Anabaptism. Regardless of the exact relationship to Anabaptism, the Zwickau Prophets presented a radical alternative to Luther and mainstream Protestantism as demonstrated in their involvement in disturbances in Wittenberg.
