<P>This book by the legendary Situationist activist and author of The Revolution ofEveryday Life examines the heretical and millenarian movements that challenged social andecclesiastical authority in Europe from the 1200s into the 1500s.Although Vaneigem discusses anumber of different movements such as the Cathars and Joachimite millenarians, his main emphasis ison the various manifestations of the Movement of the Free Spirit in northern Europe. He sees notonly resistance to the power of state and church but also the immensely creative invention of newforms of love, sexuality, community, and exchange. Vaneigem is particularly interested in theradical opposition presented by these movements to the imperatives of an emerging market-basedeconomy, and he evokes crucial historical parallels with the antisystemic rebellions of the 1960s.The book includes translations of original texts and source materials.</P>
