This book provides a unique perspective on the psychology of activism, political violence and terrorism. From an up-to-date synthesis of existing theories to an analysis of original empirical evidence on when and why people support political violence, the book offers rich, relevant and timely information about human social and political behaviors in Western democratic countries. Integrating macro-societal concerns within a psychological approach, it shows how the effects of national policies on beliefs and behaviors can be studied. Thus opening the door to an understanding of processes of influence affecting millions of people, and leading to novel insights into the social and political psychology of radical group behaviors. It extends the current understanding of the role of group relative deprivation in violent radicalism, and points to the type of national integration policy to can be most helpful in the prevention of political violence.

"The authors have skillfully used cutting edge theories and empirical research to present a compelling and insightful picture of violent radicalism. This book is very well organized and written so it can be used by undergraduate students, but it also has important lessons for experienced researchers and practitioners."

Fathali M. Moghaddam, Professor of Psychology, Georgetown University, Washington DC, author of "Political Plasticity: The Future of Democracy and Dictatorship"

"This book provides a timely comprehensive analysis of political violence, its causes and solutions. Those interested in understanding activism to radicalization and extremism will gain new insights into these forms of collective behaviour. Guimond and Nugier reveal to all, the hidden and powerful forces of group psychology."

Katherine J. Reynolds, Professor of psychology, University of Melbourne and Australian National University, Australia

"By comparing different populations, this book challenges stereotypes and sheds new light on the factors that lead ordinary people to commit political violence."
