Artists' petitions requesting a new Salon des Refusés in 1867, and again in 1872, were denied. In December 1873, Monet, Renoir, Pissarro, Sisley, Cézanne, Berthe Morisot, Edgar Degas and several other artists founded the Société anonyme des artistes peintres, sculpteurs, graveurs, etc. to exhibit their artworks independently. Members of the association were expected to forswear participation in the Salon. The organizers invited a number of other progressive artists to join them in their inaugural exhibition, including the older Eugène Boudin, whose example had first persuaded Monet to adopt plein air painting years before. Another painter who greatly influenced Monet and his friends, Johan Jongkind, declined to participate, as did Édouard Manet. In total, thirty artists participated in their first exhibition, held in April 1874 at the studio of the photographer Nadar.

Critic and humorist Louis Leroy wrote a scathing review in the newspaper Le Charivari in which, making wordplay with the title of Claude Monet's Impression, Sunrise (Impression, soleil levant), he gave the artists the name by which they became known. Derisively titling his article "The Exhibition of the Impressionists", Leroy declared that Monet's painting was at most, a sketch, and could hardly be termed a finished work.
