Fauvism was a pioneering avant-garde movement in early 20th century European art, known for its vivid, non-naturalistic colors and expressionist style. Formed by a group of French painters including Henri Matisse and André Derain, the movement focused on individual expression, separating color from representational purposes, and redefining artistic communication. Although it lasted only a few years, from 1904 to 1908, Fauvism significantly influenced modern art, paving the way for cubism and abstraction.
