DADA was born out of negative reaction to the horrors of the First World War. This international movement was begun by a group of artists and poets associated with the Cabaret Voltaire in Zurich. Dada rejected reason and logic, prizing nonsense, irrationality and intuition.
The origin of the name Dada is unclear; some believe that it is a nonsensical word. Others maintain that it originates from the Romanian artists Tristan Tzara’s and Marcel Janco’s frequent use of the words “da, da,” meaning “yes, yes” in the Romanian language. Another theory says that the name “Dada” came during a meeting of the group when a paper knife stuck into a French-German dictionary happened to point to ‘dada’, a French word for ‘hobbyhorse’.
