Joseph II (13/03/1741 – 20/02/1790), brother of Leopold II, 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. He was thus the first ruler in the Austrian dominions of the House of Lorraine, styled Habsburg-Lorraine (von Habsburg-Lothringen in German). Joseph was a proponent of enlightened absolutism; however, his commitment to modernizing reforms subsequently engendered significant opposition, which eventually culminated in an ultimate failure to fully implement his programmes. He has been ranked, with Catherine II of Russia and Frederick II of Prussia, as one of the three great Enlightenment despots.
Leopold II (05/05/1747 – 01/03/1792), brother of Joseph II, was Holy Roman Emperor from 1790 to 1792, King of Hungary, archduke of Austria, and Grand Duke of Tuscany from 1765 to 1790. He was a son of Emperor Francis I and his wife, Empress Maria Theresa. Leopold was a moderate proponent of enlightened absolutism.
