Impressionism was an art movement that began in France in the 1860s-1880s. Impressionist paintings depicted everyday subjects and the effects of light on scenes using visible brush strokes. Major Impressionist artists included Monet, Manet, Renoir, Pissarro, and Degas. They painted outdoor scenes of modern life. Post-Impressionism developed after the 1880s, rejecting naturalism and fleeting effects. Post-Impressionists like Seurat, Cézanne, Van Gogh, Gauguin, and Toulouse-Lautrec emphasized expression, structure, and form.
