Impressionism and Post-Impressionism revolutionized art in the late 19th century. These movements broke from academic traditions, focusing on capturing light, color, and everyday life. Artists like Monet, Renoir, and van Gogh developed new techniques and styles that shaped modern art. These movements emerged in Paris, reflecting rapid modernization and changing social dynamics. Impressionists painted en plein air, using visible brushstrokes and bright colors. Post-Impressionists like Cézanne and van Gogh pushed further, developing more personal, expressive styles that influenced later avant-garde movements.
