Post-Impressionism (also spelled Postimpressionism) is a predominantly French art movement that developed roughly between 1886 and 1905; from the last Impressionist exhibition to the birth of Fauvism. Post-Impressionism emerged as a reaction against Impressionists’ concern for the naturalistic depiction of light and colour. Due to its broad emphasis on abstract qualities or symbolic content, Post-Impressionism encompasses Neo-Impressionism, Symbolism, Cloisonnism, Pont-Aven School, and Synthetism, along with some later Impressionists' work. The movement was led by Paul Cézanne, Paul Gauguin, Vincent van Gogh, and Georges Seurat.
