In 1855, Courbet exhibited the vast Painter's Studio (Louvre). Attacked by academic painters, he set up his own pavilion where he exhibited 40 of his paintings and issued a manifesto on realism. While he continued to provoke the establishment by submitting works to the Salon that were twice rejected in the mid-1860s, within that decade he triumphed as the leader of the realist school. His influence became enormous, reaching its height with his rejection of the cross of the Legion of Honor offered him by Napoleon III in 1870. Under the Commune of Paris (1871), Courbet was president of the artists' federation and initially active in the Commune; he was later unfairly held responsible, fined, and imprisoned for the destruction of the Vendôme column. In 1873 he fled to Switzerland, where he spent his few remaining years in poverty. Although his aesthetic theories were not destined to prevail, his painting is greatly admired for its frankness, vigor, and solid construction.
