When violence broke out at the demonstrations surrounding the 2001 G8 summit in Genoa, Italy, the authors of this book were there. The protests proved to be a critical moment in the global justice movement. Presenting the first systematic empirical research on the global justice movement, Globalization from Below analyzes a movement from the viewpoints of the activists, organizers, and demonstrators themselves. To understand how this cycle of global protest emerged, the authors examine the interactions between challengers and elites, and discuss how these new models of activism fit into current social movement work.
