This book offers an original assessment of the ways in which the sociocultural code of blood revenge and its modern remnants shape irregular warfare.

Despite being a common driver of communal violence, blood revenge has received little attention from scholars. With many civil wars and insurgencies occurring in areas where the custom lingers, strengthening our understanding of blood revenge is essential for discerning how conflicts change and evolve. Drawing upon extensive multidisciplinary evidence, this book is the first in the literature on civil war and insurgency to analyse the impact of blood revenge and its modern remnants on irregular warfare. Even when blood revenge undergoes erosion, its unregulated version still shapes the social fabric of insurgency, although in different ways than its institutionalised counterpart. At times of political instability, the presence of a culture of retaliation weighs heavily on the dynamics of violent mobilisation, target selection, recruitment, and disengagement. This book brings in evidence from dozens of conflicts, providing unprecedented insights into how a better understanding of blood revenge can improve military blueprints for irregular warfare.

This book will be of much interest to students of insurgency, terrorism, military and strategic studies, anthropology, and sociology, as well as to decision-makers and irregular warfare professionals.
