Post-Impressionism is an art movement that emerged in the late 19th century, following Impressionism. Artists like Vincent van Gogh, Paul Cézanne, and Georges Seurat sought to express their emotions and ideas through bold colors and innovative techniques, moving beyond the fleeting effects of light that characterized Impressionism. This movement is known for its diverse styles and approaches, including the use of pointillism by Seurat and the emotional intensity of van Gogh's works. Post-Impressionism laid the groundwork for modern art, influencing various movements such as Fauvism and Expressionism with its emphasis on personal expression and abstraction.
