This book explores the phenomenon of Rainbow Gatherings in Europe. These countercultural events form radically alternative temporary societies in the peripheries of modern states and manage themselves without centralized power, market economy or institutionalized forms of religion. The volume offers a vivid description of life in the Gatherings, analyses the main ideological tenets and places the meetings in historical and cultural context. It considers how the Rainbow Gathering tradition is rooted in networks of alternative spirituality and environmental counterculture but also reflects broader shifts in religion and religiosity.
