Matisse sought to convey emotion and sensation through bold colors and simplified forms, leading to the development of the Fauvism movement. His travels and exposure to diverse cultures further influenced his work, inspiring him to incorporate elements from various artistic traditions. Throughout his career, Matisse continually experimented with different media, including painting, sculpture, and collage, ultimately establishing himself as one of the most important figures in 20th-century art.
