For 100 years Dadaism has been praised because of its influence and importance as one of the most important avant-garde movements.
Beginning in Zurich during World War I, it quickly became an international phenomenon spreading to various cities in Europe and America. Opposing the cultural and intellectual conformity in art, usually displaying political affinities with the radical left, dada artists gathered and engaged in activities such as public gatherings, demonstrations, and publication of art and literary journals.
In regards to the visual art, the new concept praising the idea above the subject was born. Marcel Duchamp is the father figure of the movement and his experimental nature brought forward new ideas such as readymades. Influential for the original understanding towards sculpture production, idea of the readymades also influenced assemblage, found object pieces, and to an extent junk art and recycled art as well. Praising machines, technology and Cubist elements were features evident in the dada collage pieces and other innovative artworks this 1920s art period left behind.
