In Ordinary Rebels: Rank-And-File Militants Between War and Peace (Oxford University Press, 2025), Kolby Hanson argues that these periods of state toleration do not simply change armed groups' behavior, but fundamentally transform the organizations themselves by shaping who takes up arms and which leaders they follow. This book draws on a set of innovative experimental surveys and 75 in-depth interviews tracing four armed movements over time in Northeast India and Sri Lanka. A powerful new theory of how conditions shape the trajectory of non-state armed groups, this book reshapes our understanding of why such organizations become more moderate over time.
