In post-war Europe, protest was everywhere. On both sides of the Iron Curtain, from Paris to Prague, Milan to Wroclaw, ordinary people took to the streets, fighting for a better world. Their efforts came to a head most dramatically in 1968 and 1989, when mass movements swept Europe and rewrote its history. In the decades between, Joachim C. Häberlen argues, new movements emerged that transformed the nature of protesting. Activism moved beyond traditional demonstrations, from squatting to staging 'happenings' and camping out at nuclear power plants. New movements were born, notably anti-racism, women's liberation, gay liberation, and environmentalism. Some of these struggles succeeded, others failed. But successful or not, their history provides a glimpse into roads not taken, into futures that did not happen.
