was the driving force behind many classic styles, including the
Picasso Blue Period, Rose
Period and maybe most important, Cubism.
Its innovations gave rise to a host
of other 20th-century art movements, including futurism in Italy,
suprematism and constructivism in Russia, de Stijl in the Netherlands,
and vorticism in England. Cubism also influenced German expressionism,
dada, 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.
