Fauvism was an early 20th century avant-garde art movement known for its use of vibrant, wild, and pure colors and a simplified use of forms. It originated around 1905 in reaction to the then-dominant Impressionism movement and was influenced by Post-Impressionism. Key Fauvist artists included Henri Matisse, André Derain, and Maurice de Vlaminck, who were connected by their expressive techniques and concepts though their individual styles differed. While short-lived, Fauvism had a significant influence on freeing color use and the boundaries of artistic representation.
