Dadaism was an anti-art movement started in 1916 in Zurich, Switzerland in response to World War I. It spread after the war and rebelled against nationalist policies. Dadaists experimented with new forms of expression and chose their name, meaning 'hobby horse', randomly. The Cabaret Voltaire in Zurich was the birthplace of Dadaism, bringing together exiled artists like Hugo Ball, Emmy Hennings, Jean Arp, and others. Dadaism had no inherent meaning and interpretations depended on the viewer.
