Situationism

…the Situationist International (1957–1972), a group of avant-garde artists and political theorists united by their opposition to advanced capitalism. At varying points the group’s members included the writers Raoul Vaneigem and Michèle Bernstein, the artist Asger Jorn, and the art historian T.J. Clark. Inspired primarily by Dadaism, Surrealism, and Marxist philosophy, the SI rose to public prominence during the May 1968 demonstrations during which members of the group participated in student-led occupations and protests.
