Josephinism is a name given collectively to the domestic policies of Joseph II, Holy Roman Emperor (1765–1790). During the ten years in which Joseph was the sole ruler of the Habsburg monarchy (1780–1790), he attempted to legislate a series of drastic reforms to remodel Austria in the form of what liberals saw as an ideal Enlightened state. This provoked severe resistance from powerful forces within and outside his empire, but ensured that he would be remembered as an "enlightened ruler" by historians from then to the present day.

Joseph II was Holy Roman Emperor from 18 August 1765 and sole ruler of the Habsburg monarchy from 29 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, Leopold II, 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.
