The Situationist International was a restricted group of international revolutionaries founded in 1957, and which had its peak in its influence on the unprecedented general wildcat strikes of May 1968 in France. With their ideas rooted in Marxism and the 20th-century European artistic avant-gardes, they advocated experiences of life being alternative to those admitted by the capitalist order, for the fulfillment of human primitive desires and the pursuing of a superior passional quality. For this purpose they suggested and experimented with the "construction of situations", namely the setting up of environments favorable for the fulfillment of such desires. Using methods drawn from the arts, they developed a series of experimental fields of study for the construction of such situations, like unitary urbanism and psychogeography. They fought against the main obstacle on the fulfillment of such superior passional living, identified by them in advanced capitalism. Their theoretical work peaked on the highly influential book "The Society of the Spectacle" by Guy Debord. Debord argued in 1967 that spectacular features like mass media and advertising have a central role in an advanced capitalist society, which is to show a fake reality in order to mask the real capitalist degradation of human life. Raoul Vaneigem wrote "The Revolution of Everyday Life" which takes the field of "everyday life" as the ground upon which communication and participation can occur, or, as is more commonly the case, be perverted and abstracted into pseudo-forms.
