Joseph II (Joseph Benedikt Anton Michael Adam; 13 March 1741 – 20 February 1790) was Holy Roman Emperor from 1765 to 1790 and ruler of the Habsburg lands from 1780 to 1790. He was the eldest son of Empress Maria Theresa and her husband, Francis I, and was the brother of Marie Antoinette. He was thus the first ruler in the Austrian dominions of the House of Lorraine, styled Habsburg-Lorraine (von Habsburg-Lothringen in German).
