For all the academic and policy interest in Nigeria’s Boko Haram insurgency, the coping strategies of civilians who survive amid everyday violence have received relatively little attention. Focusing on the Civilian Joint Task Force (CJTF), a pro-government militia fighting Boko Haram in northeastern Nigeria, Agbiboa explores how and why the group emerged, the nature of its relationship with the state and local communities, and how counterinsurgent vigilantism affects the prospects for peace. A focus on vigilantes and civil militias vis-à-vis the state points to the vital role of civil-military cooperation for effective counterinsurgency campaigns and for reducing state violence against civilians. At the same time, it underscores the precariousness of protection both in terms of increasing the targeting of civilians by vengeful insurgents as well as the tendency for civilian defense groups to “turn bad” and become threats to the communities they were expected to protect.
