Situationism is the theory that behavior is mainly a response to immediate situations. 

The situationist international was a group of social revolutionaries, which was made up of artists, political theorists and intellectuals which started in 1957 and ended in 1972. Guy Debord was one of the members who stuck out the most.  At first the situationists were concerned about how art had been held back and wanted to make art and culture one in everyday life. Then they became concerned about the capitalist society. They believed that capitalism gave humans dissatisfaction so  human desire needed to be fulfilled by finding an alternative to a capitalist society. They are well known for their wildcat strikes and riots in Paris 1957 where there were general strikes all across France which almost put Frances capitalist economy on a stop although the strike did turn violent it was mostly artistic it included things such as songs, graffiti’s and posters.

Tom Pope was inspired by the situationists, I think there is a link between the work he does and the situationists because Tom Pope looks for a reaction and he challenges the norms by pushing boundaries.
