As nouns the difference between dadaism and expressionism

is that dadaism is a cultural movement that began in neutral Zürich, Switzerland, during World War I and peaked from 1916 to 1920, which involved visual arts, literature (poetry, art manifestos, art theory), theatre, and graphic design, which concentrated its anti-war politic through a rejection of the prevailing standards in art through anti-art cultural works while expressionism is a movement in the arts in which the artist did not depict objective reality, but rather a subjective expression of their inner experiences.
