Impressionism revolutionized art by capturing fleeting moments and the effects of light,  it emerging in the late 19th century. It moved away from strict realism, focusing instead on emotion, color, and everyday scenes.
Key artists include Claude Monet, Edgar Degas, Vicent Van Gogh, and Pierre-Auguste Renoir, who used loose brushstrokes and vibrant colors to convey movement and atmosphere. Impressionism laid the groundwork for modern art, influencing movements like Post-Impressionism and Fauvism.
