Provo, which existed from May 15, 1965 until May 13, 1967, had its roots in the happenings performed by Robert Jasper Grootveld at the Lieverdje statue at Spui square in Amsterdam, The Netherlands and the anarchist activities of Roel van Duyn and Rob Stolk. It developed into a anarchist movement that spread out to the rest of Holland, Belgium and beyond. Provo’s playful revolt had a profound influence on countercultural groups as the diggers and the yippies. See also: www.provo-images.info.
