On Revolutions integrates insights from diverse fields—civil resistance studies, international relations, social movements, terrorism—to offes new ways of thinking about the study of revolution. Conventional lines of thought draw on a number of categorical distinctions: social versus political revolutions, structure versus agency, violent versus nonviolent strategies, domestic versus international factors, and success versus failure. In contrast, the book outlines an approach that reaches beyond these dichotomies. Revolutions are not just political or social—they feature many types of change. Structure and agency are not mutually distinct—they are mutually reinforcing processes. Contention is not just violent or nonviolent—it is a messy process that usually involves both strategies. Revolutions do not just succeed or fail—they achieve and simultaneously fall short. And causal conditions are not just domestic or international—they are dependent on the interplay of each. The merit of this approach is demonstrated through consideration of a wide range of cases. The volume also explores new opportunities for conceptual thinking about revolution, provides methodological advice, and engages with the ethical issues that exist at the nexus of scholarship and activism. Taken together, these innovations chart a new path for revolution studies.
