Henri Matisse belonged to which art movement?

Henri Émile Benoît Matisse (31 December 1869 – 3 November 1954) was a French artist, known for both his use of colour and his fluid and original draughtsmanship. He was a draughtsman, printmaker, and sculptor, but is known primarily as a painter. Matisse is commonly regarded, along with Pablo Picasso, as one of the artists who best helped to define the revolutionary developments in the visual arts throughout the opening decades of the twentieth century, responsible for significant developments in painting and sculpture.

The intense colorism of the works he painted between 1900 and 1905 brought him notoriety as one of the Fauves (wild beasts). Matisse was recognised as a leader of the Fauves, along with André Derain; the two were friendly rivals, each with his own followers. Fauvism as a style began around 1900 and continued beyond 1910. The movement as such lasted only a few years, 1904–1908, and had three exhibitions.

Many of Matisse's finest works were created in the decade or so after 1906, when he developed a rigorous style that emphasized flattened forms and decorative pattern. In 1917 he relocated to a suburb of Nice on the French Riviera, and the more relaxed style of his work during the 1920s gained him critical acclaim as an upholder of the classical tradition in French painting. After 1930, he adopted a bolder simplification of form.
