Mühlhausen is one of the oldest towns in Thuringia, and is said to have been fortified in 925. Its early importance is shown by the grant of privileges made to it by the German King Henry I., and by the diet held here in 1135. During the Reformation period Miihlhausen became notorious as one of the chief seats of the Anabaptists. Thomas Miinzer, one of their leaders, was captured in the vicinity and executed in the town. Internal dissensions and injuries received during the Thirty Years' War and, the Seven Years' War afterwards reduced Miihlhausen to unimportance. In 1802 it lost its independence and passed to Prussia, in 1807 it was attached to the kingdom of Westphalia, but in 1815 it again became Prussian. The Teutonic Order established itself at Miihlhausen in 1200.
