Based on decades of psychological research and personal experience, Fathali M. Moghaddam presents a new and dynamic introduction to the psychology of revolution. He sets out to explain what does and does not change with revolution, using the concept of political plasticity or the malleability of political behavior. In turn, psychological theories of collective mobilization, the process of regime change, and explanations of what happens after regime change are discussed. This psychological analysis of the post-revolution period is pertinent because it explains why revolutions so often fail. General readers interested in learning more about the psychology of revolution, as well as students, researchers, and teachers in political psychology, political science, and collective action, will find this book accessible and beneficial.
