The role of the peasantry during the Algerian War of Independence (1954-1962) has long been neglected by historians, in part because they have been viewed as a ‘primitive’ mass devoid of political consciousness. *War in the Mountains: Peasant Society and Counterinsurgency in Algeria, 1918-1958* challenges this conventional understanding by tracing the ability of the peasant community to sustain an autonomous political culture through family, clan, and village assemblies. The long-established system of indirect rule by which the colonial state controlled and policed the vast mountainous interior of Algeria began to break down after the 1920s. *War in the Mountains* explains how competing guerrilla forces and the French military sought to harness djemâas as part of a hearts-and-minds strategy. Djemâas formed a pole of opposition to the patron-client relations of the rural élites, with clandestine urban-rural networks emerging that prepared the way for armed resistance and a system of rebel governance. Contrary to accepted historical analysis suggesting that rural society was massively uprooted and dislocated, *War in the Mountains* demonstrates that the peasantry demonstrated a high level of social cohesion and resistance based on powerful family and kin networks.
