Joseph II, Holy Roman Emperor (d. 1790)
Joseph II (German: Josef Benedikt Anton Michael Adame; English: Joseph Benedict Anthony Michael Adam; 13 March 1741 – 20 February 1790) was Holy Roman Emperor from August 1765 and sole ruler of the Habsburg lands from November 1780 until his death. He was the eldest son of Empress Maria Theresa and her husband, Emperor Francis I, and the brother of Marie Antoinette, Maria Carolina of Austria and Maria Amalia, Duchess of Parma. He was thus the first ruler in the Austrian dominions of the union of the Houses of Habsburg and Lorraine, styled Habsburg-Lorraine.

Joseph was a proponent of enlightened absolutism; however, his commitment to secularizing, liberalizing and modernizing reforms resulted in significant opposition, which resulted in failure to fully implement his programs. Meanwhile, despite making some territorial gains, his reckless foreign policy badly isolated Austria. He has been ranked with Catherine the Great of Russia and Frederick the Great of Prussia as one of the three great Enlightenment monarchs. False but influential letters depict him as a somewhat more radical philosophe than he probably was. His policies are now known as Josephinism.

He was a supporter of the arts, and most importantly of composers such as Wolfgang Amadeus Mozart and Antonio Salieri. He died with no surviving children and was succeeded by his younger brother Leopold II.
