This book focuses on the different types of combatants in conflicts in Africa, exploring the fine lines between what might be classified as a militia in one conflict, a rebel in another, or a terrorist in a third.Drawing on the work of Carl von Clausewitz, this book provides a conceptually stable and analytically sound new typology on combatants. Analysing the relationships between state and society, and drawing on Clausewitz's Trinity of passion, chance, and reason, the book presents a set of five types of armed actors: Professionals, Praetorians, Militias, Insurgents, and Mercenaries. Each type is developed through a close reading of foundational theoretical texts, reviews of contemporary studies, and a historical analysis of their unique characteristics. Unlike a reductionist binary perspective, this typology accounts for the dynamic, complex, and evolving relationships of these actors with the state and society.A typology of combatants in conflicts in Africa can provide avenues for more in-depth analysis of such conflicts and holds implications for Security Sector Reform projects and other peace-building programmes. As such, this book will be an essential reference for scholars and students of African Politics and Military and Security Studies.
