The Situationist International was a small group of international political and artistic agitators with roots in Marxism and Lenninism. They played a central role in the theory underlying the 1968 European uprisings. They managed to use public money to publish Mustapha Khayati's pamphlet On the Poverty of Student Life and distributed thousands of copies, making the Situationists well known throughout the non-Stalinist left. They were among the occupiers of the Sorbonne and defended barricades in the riots. A part of the FORuM Project Publication series published in association with the Temple Hoyne Buell Center for the Study of American Architecture at Columbia University, 50 Years of Recuperation of the Situationist International is a pointed, original and engaged investigation of what remains vital in the endlessly provocative legacy of the Situationist International (SI) 1957-1972, one of the most important and political avant-garde groups to emerge after World War II; and how this might open the way to new practices in today's digital culture.
