1) In the early 20th century, Dada was an art movement of the European avant-garde, with early centres in Zürich, Switzerland and New York. The Dada movement, formed in response to World War I, consisted of artists who in their works rejected the logic, purpose, and aestheticism of contemporary capitalist society, instead voicing nonsense, irrationality, and anti-bourgeois protest. The art of the movement, including collage, sound poetry, cut-up prose, and sculpture, included visual, literary, and sound media. Dadaist artists shared their frustration with crime, war and nationalism, as well as maintaining political affinities with the radical left.
