Dada or Dadaism was an art movement of the European avant-garde in the early 20th century, with early centres in Zürich, Switzerland, at the Cabaret Voltaire, founded by Hugo Ball with his companion Emmy Hennings, and in Berlin in 1917. New York Dada began c. 1915, and after 1920 Dada flourished in Paris. Dadaist activities lasted until the mid 1920s.

An art movement is a tendency or style in art with a specific art philosophy or goal, followed by a group of artists during a specific period of time, or, at least, with the heyday of the movement defined within a number of years. Art movements were especially important in modern art, when each consecutive movement was considered a new avant-garde movement. Western art had been, from the Renaissance up to the middle of the 19th century, underpinned by the logic of perspective and an attempt to reproduce an illusion of visible reality. By the end of the 19th century many artists felt a need to create a new style which would encompass the fundamental changes taking place in technology, science and philosophy.
