Avant-garde art movement in the early 20th century
Dada () or Dadaism was an anti-establishment art movement that developed in 1915 in the context of the Great War and the earlier anti-art movement. Early centers for dadaism included Zürich and Berlin. Within a few years, the movement had spread to New York City and a variety of artistic centers in Europe and Asia. Within the umbrella of the movement, people used a wide variety of artistic forms to protest the logic, reason, and aestheticism of modern capitalism and modern war. To develop their protest, artists tended to make use of nonsense, irrationality, and an anti-bourgeois sensibility.
