Because of his many innovations, Picasso is widely considered to be the most influential artist of the 20th century. The cubist movement, which he and Braque inspired, had a number of followers. Its innovations gave rise to a host of other 20th-century art movements, including futurism in Italy, suprematism and constructivism in Russia, and other movements as well as early work of the surrealists and abstract expressionists. In addition, collage and construction became key aspects of 20th-century art.
