Post-Impressionism developed in the late 1880s as artists sought to move beyond Impressionism by adding more structure like line and shape rather than just loose brushwork. Key Post-Impressionist artists included Seurat, Gaugin, Cezanne, Toulouse-Lautrec, and Van Gogh, who were based primarily in France. Cezanne in particular is highlighted for his paintings of Mount Sainte Victoire from the late 1890s to early 1900s, which showed his experimentation with color and form beyond Impressionism.
