Collective action is one of the core mechanisms of social change, and thus of major importance to social scientists, practitioners, and policy-makers. This book brings together recent insights on the social and psychological dynamics of collective action and social change, with contributions from around the world. The key theme in this book is that there is considerable diversity in collective action, and that understanding this diversity facilitates a better understanding of collective action and social change.
