Social movement scholars have become increasingly interested in the role of stories in contentious politics. Stories may facilitate the mobilization of protestors or strengthen the resonance of movement claims within public discourse and institutional politics. This book examines the role of narratives in building collective identity – a vital element in activists’ continued commitment. While often claimed important, the connection between narratives and movement identity has received little attention in empirical research so far. The book analyses and compares the role of narratives in building collective identity in the Global Justice Movement (GJM), a movement known for its diversity of groups and political perspectives. The book compares three national constellations of the Global Justice Movement in Europe (Italy, Germany, and Poland) drawing on a rich pool of original data.
