The modern world will become increasingly meaningless by the atrocities of war, class inequality and false traditions.



Cabaret Voltaire : Artists, Poets
Dada was founded on a rejection of to the horrors of World War I. This international movement was begun by a group of artists and poets in Zurich. Dada rejected reason and logic, favoring nonsense, irrationality and intuition as a form of reflectio about modern society, which they felt was increasingly meaningless. "Dada is the groundwork to abstract art and sound poetry, a starting point for performance art, a prelude to postmodernism, an influence on pop art, a celebration of antiart to be later embraced for anarcho-political uses in the 1960s and the movement that lay the foundation for Surrealism." - Marc Lowenthal, translator's introduction to Francis Picabia's I Am a Beautiful Monster: Poetry, Prose, And Provocation
The movement primarily involved visual arts, literature, poetry, art manifestoes, art theory, theatre, and graphic design, and concentrated its anti-war politics through a rejection of the prevailing standards in art through anti-art cultural works. In addition to being anti-war, Dada was also anti-bourgeois and had political affinities with the radical left.
