Jean Desire Gustave Courbet (French: [gystav kuRbe]; 10 June 1819 - 31 December 1877) was a French painter who led the Realism movement in 19th-century French painting. Committed to painting only what he could see, he rejected academic convention and the Romanticism of the previous generation of visual artists. His independence set an example that was important to later artists, such as the Impressionists and the Cubists. Courbet occupies an important place in 19th-century French painting as an innovator and as an artist willing to make bold social statements through his work.

In the Salon of 1857 Courbet showed six paintings. These included Young Ladies on the Banks of the Seine (Summer), depicting two prostitutes under a tree, as well as the first of many hunting scenes Courbet was to paint during the remainder of his life: Hind at Bay in the Snow and The Quarry.  Young Ladies on the Banks of the Seine, painted in 1856, provoked a scandal. Art critics accustomed to conventional, "timeless" nude women in landscapes were shocked by Courbet's depiction of modern women casually displaying their undergarments.  By exhibiting sensational works alongside hunting scenes, of the sort that had brought popular success to the English painter Edwin Landseer, Courbet guaranteed himself "both notoriety and sales". During the 1860s, Courbet painted a series of increasingly erotic works such as Femme nue couchee.  This culminated in The Origin of the World (L'Origine du monde) (1866), which depicts female genitalia and was not publicly exhibited until 1988, and Sleep (1866), featuring two women in bed. The latter painting became the subject of a police report when it was exhibited by a picture dealer in 1872.  Until about 1861, Napoleon's regime had exhibited authoritarian characteristics, using press censorship to prevent the spread of opposition, manipulating elections, and depriving Parliament the right to free debate or any real power. In the 1860s, however, Napoleon III made more concessions to placate his liberal opponents. This change began by allowing free debates in Parliament and public reports of parliamentary debates. Press censorship, too, was relaxed and culminated in the appointment of the Liberal Emile Ollivier, previously a leader of the opposition to Napoleon's regime, as the de facto Prime Minister in 1870. As a sign of appeasement to the Liberals who admired Courbet, Napoleon III nominated him to the Legion of Honour in 1870. His refusal of the cross of the Legion of Honour angered those in power but made him immensely popular with those who opposed the prevailing regime.
