Dada (/ˈdɑːdɑː/) 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. Developed in reaction to World War I, the Dada movement consisted of artists who rejected the logic, reason, and aestheticism of modern capitalism, instead expressing nonsense, irrationality, and anti-bourgeois protest in their works.
