In 1525 during the German Peasants' War, Eitelhans Ziegelmüller, one of the peasant commanders, took Bermatingen and used it as a base to attack towns, castles and monasteries in the surrounding region as far as Buchhorn (modern Friedrichshafen). The peasants marched to battle at Weingarten by late April where they made peace with the forces of the Swabian League under George III Truchsess of Waldburg-Zeil, agreeing to end the insurrection and returning property to its feudal owners in exchange for improved conditions and right to arbitration in disputes.
