By 1930, Modernism had won a place in the establishment, including the political and artistic establishment, although by this time Modernism itself had changed. There was a general reaction in the 1920s against the pre-1918 Modernism, which emphasized its continuity with a past while rebelling against it, and against the aspects of that period which seemed excessively mannered, irrational, and emotional. The post-World-War period, at first, veered either to systematization or nihilism and had, as perhaps its most paradigmatic movement, Dada.
