Blood Feud

A blood feud is a state of prolonged retaliatory conflict between two kin groups, families, or clans, typically initiated by a killing, serious injury, or grave insult, in which the offended group considers itself obligated to take vengeance against the offending group or its kin, and each act of retaliation risks provoking a further act of retaliation in turn, potentially sustaining the conflict across generations unless it is formally ended through compensation, mediation, or reconciliation ritual. The practice has been ethnographically and historically documented across a wide range of societies, including highland Albania, where the customary legal code known as the Kanun of Leke Dukagjini codified elaborate rules governing when and how blood feuds could be pursued and resolved, Corsica and other parts of Mediterranean Europe, where the term vendetta describes closely related practices, the Scottish Highlands clan system, and numerous societies in the Middle East, the Caucasus, and elsewhere organized around strong lineage or clan loyalty. Anthropologists have generally analyzed blood feud not simply as uncontrolled violence but as a socially regulated institution, often bound by explicit customary rules about proportionality, eligible targets, and paths to resolution, that functions in societies lacking a centralized state monopoly on legitimate force as a mechanism for enforcing group honor and deterring offenses against kin.
