The remaining branch went extinct in the male line in 1740 with the death of Holy Roman Emperor Charles VI and completely in 1780 with the death of his eldest daughter, Maria Theresa of Austria. It was succeeded by the Vaudemont branch of the House of Lorraine. The new successor house styled itself formally as House of Habsburg-Lorraine (German: "Habsburg-Lothringen"), although it was often referred to as simply the House of Habsburg.
