Vigilante groups have been successful in providing local security. But subcontracting security functions to vigilante groups for counter-insurgency purposes is a dangerous option for fragile African states. African leaders should set clear objectives and mandates when enlisting vigilantes and invest in disarmament, demobilisation and reintegration programs.

Drawing on four illustrative cases – Sierra Leone, Uganda’s Teso region, South Sudan’s former Western Equatoria State and Nigeria’s north east – this report seeks to shed light on factors that determine vigilantes’ evolution and impact on security and stability with the objective of helping governments and their international partners navigate this dilemma.
