Dada

Dada was, officially, not a movement, it's artists not artists and it's art not art.
That is the simplistic explanation.
Dada was created in Europe during the first world war when the French and German artists, writers and intellectuals found themselves gathered in the refuge that Zurich offered. The group protested as a group and used any public forum they could find to metaphorically spit on the nationalism, rationalism, materialism, and any other ism which they felt contributed to the war. 'If society is going in this direction, they said we'll have no part of it or it's traditions. Including...no, wait;...especially artistic traditions. We, who are non-artists, will create non-art since art (and everything else in the world) has no meaning.'
