French Modernism is an artistic movement that began in the late 19th century and was heavily influenced by the works of Henri Matisse. Matisse was a French artist who is widely considered to be one of the most influential painters of the 20th century. He was known for his use of bold colors and expressive brushwork, which helped to define the modernist movement. His works often featured abstract shapes and vibrant colors, which were seen as a rejection of traditional art forms. Matisse's works are still highly regarded today and have had a lasting impact on the art world.
