City, on the Mulde River in Saxony, 42 mi S of Leipzig. Slavic in origin, it was first mentioned in 1118 as a trading center and was chartered in 1212. It developed into a free imperial city in the 12th century until it passed to the margraves of Meissen in 1323. It became the center of the Anabaptist movement of Thomas Münzer between 1520 and 1523. It was often plundered during the Thirty Years’ War of 1618 to 1648. The city was a center of a rich coal field that was first worked in the early 19th century, which was the basis of industrial development in the city. The composer Robert Schumann was born here in 1810; a Schumann museum was opened in 1956.
