The ruling family having become extinct in 1496, it passed to that of Mansfeld. In 1635, by the peace of Prague, it was ceded to the elector of Saxony, John George I., who handed it over to his son Augustus of Saxe-Weissenfels; but in 1746 it was again united with electoral Saxony. It was incorporated with Prussia in 1815.
