Drawing on a wide range of social science disciplines and approaches, each chapter in this book offers a comprehensive analysis of social protest, political dissent and collective action. The distinguished scholars contributing to the book discuss some of the key theoretical and methodological issues in social protest research, and analyse recent instances of collective dissent around the globe, ranging from the 15M movement in Spain, to the 2011 Salford riots in the UK, to Pro-Palestinian activism in Jerusalem. The result of these contributions is a sophisticated and multifaceted collection that enriches our understanding of why, when, and how groups of people decide to act collectively in order to pursue political change. The book is a timely testament to the vitality of the field. This book was originally published as a special issue of Contemporary Social Science.
