In 1863 Napoleon III created by decree the Salon des Refusés, at which paintings rejected for display at the Salon of the Académie des Beaux-Arts were to be displayed. The artists of the refused works included the young Impressionists, who were considered revolutionary. Cézanne was influenced by their style but his social relations with them were inept—he seemed rude, shy, angry, and given to depression. His works of this period are characterized by dark colours and the heavy use of black. They differ sharply from his earlier watercolours and sketches at the École Spéciale de dessin at Aix-en-Provence in 1859, and their violence of expression is in contrast to his subsequent works.
