Dada is an artistic reaction to the chaos and absurdity of the first world war, and to the subconscious part of the mind. The movement produced many artists (e.g. Hugo Ball, Emmy Hennings, Raoul Hausmann, Hannah Höch, Tristan Tzara, Francis Picabia, Kurt Schwitters) and its centers can be found around the globe. For example: Zurich, Berlin, Paris, New York to name a few.
A number of new art forms emerged out of Dada including concrete poetry (which can also be found in Futurism) and Surrealism.
Dada produced a large number of magazines none of which were coordinated in any way. The spreading of disinformation, and copius self-promotion both appear to have been in the Dada spirit.
Oddly enough formally/artistically the Dada movement grew out of Futurism, yet philosophically (especially on the issues of war and feminism) the two movements couldn’t be further apart.
