Prince-Bishop of Münster, Osnabrück, and Minden in the Lower Rhenish–Westphalian Circle of the Holy Roman Empire. He suppressed the Münster Rebellion, a millenarian Anabaptist theocratic insurrection which occupied the fortified city of Münster. When the Lutheran movement gave way to the radical Anabaptists in the annual council election on 23 February 1534, Waldeck besieged the city. On Easter Sunday, 1534, Anabaptist leader Jan Matthys led a small band out of the city and was defeated and killed. John of Leiden then installed himself as king of the city of New Jerusalem (Münster).
