Sustaining Peace After Civil War: Insights from 48 Recent Cases (Springer, 2026) examines one of the most important questions in peace research: What leads to enduring peace after civil wars, and what leads to the resurgence of violence? For decades, intrastate conflicts have been the predominant form of armed conflict, and most recent civil wars were conflicts that recurred. The research presented in this book focuses on influenceable factors, first and foremost on the type of civil war termination and on the post-civil war order that is shaped by the distribution of military power between the former warring parties and the scale of political compromise. Moreover, it shows that the peacekeeping environment has a major influence on whether peace endures.The insights provided in this book are relevant for the academic community, and for decision-makers and practitioners involved in civilian or military efforts to establish and preserve peace.
