The document discusses the origins and key ideas of the Dada art movement, which began in 1916 in Zurich at Hugo Ball's Cabaret Voltaire. It highlights early Dada artists like Tristan Tzara, Marcel Duchamp, and Hans Arp who pioneered techniques like collage, photomontage, assemblage, and readymades, where everyday objects were presented as art. The original Dada manifesto by Tristan Tzara advocated finding art in chance encounters rather than following conventions.
