Dada A movement in art and literature, founded in Switzerland in the early twentieth century, which ridiculed contemporary culture and conventional art. The Dadaists shared an antimilitaristic and antiaesthetic attitude, generated in part by the horrors of World War I and in part by a rejection of accepted canons of morality and taste. The anarchic spirit of Dada can be seen in the works of Duchamp, Man Ray, Hoch, Miro, and Picasso. Many Dadaists later explored Surrealism.
