The Social Tripodal Insurgency Model describes the Boko Haram insurgent group as Historical Violent Mono-defaced Socio-Cultural group. Insurgency, according to this Model, rests on three critical but interdependent conditions, namely: knowledge, reality and the society that led to the phenomenon of the Boko Haram insurgency in the north eastern region of Nigeria and how the interplay of these conditions negatively affects the social structure and social relationships in the Nigerian society. Suggested here in this research is proposition that insurgency is directly proportional to the knowledge base of the individual within the affected region, influenced by, to form realities of the universe as the reinforcement of cultural components of individual during socialisation process in the affected region remains constant. Most available researches on insurgency addressed the issues of how to resolve insurgency but laid negligible emphasis on the root cause of the social facts and the cultural forces surrounding it. Mills (2013), in the Law of Sufficient Reasons, argued that, there must be sufficient explanation as to why insurgency exists in the first place. Again, corroborating, the theory of incompleteness, he asserted that killing and meaningless destruction of property for the insurgent recruits to the Boko Haram group is considered to be normal and a way of life in their own logical realm, while the larger society viewed their actions as criminal. Therefore, Social Tripodal Insurgency Model tried to locate the differential logical realms while attributing these differences to an individual socialisation process. Three social facts are identified as crucial components; these are knowledge, reality and the effects of insurgent activities on the society. The theory of incompleteness argues that the Boko Haram socialisation process is thus incomplete.
