The Nigeria military as a product of colonialism became a veritable institution imbued with the constitutional mandate to protect the territorial integrity of the country and as well maintain robust civil-military relations necessary for nation building in the post independent Nigeria. This expectation was greeted with much char grin and fiasco, when ethnicity which was implanted by the colonial imperialism as a Pandora box imploded the First Republic in the post independent Nigeria. When the political impasse and imbroglio became nauseating and ad nauseam attesting to the inability of the civil authority to address the nation building challenges confronting Nigeria in the incipient stage of her political independence; it became imperative and behoves on the prestigious military institution to rise to these nation building challenges forthwith. It was on the basis of this background and ambience that the military revolution of 15 th January 1966 was staged to save the nation from drifting into political doldrums and abyss. This scenario offered the military the opportunity to impact and contribute to nation building and political development in Nigeria. The paper examines and analyses how far the military has contributed in addressing nation building challenges that have impacted in the overall political development of Nigeria. The paper also looks at how the military institution has assisted the civil authority in addressing nation building challenges in the Fourth Republic. KEYWORDS: Constitution, Ethnic, Independence, Military, Militia, Nigeria INTRODUCTION Nigeria came to political independence with myriad of nationhood challenges and thorny political problems that threatened its foundation and corporate existence. It will be recalled that Nigeria prior to 1914 amalgamation had over four hundred ethnic groups or tribes (Kirk-Greene 1960). Most of these have their own distinct languages, religions, traditions, and institutions. These were indeed in the Nigerian context where there were really different nationalities, which united and established a political union in the form of federation, as a result of historical circumstances (Nwankwo & Ifejika, 1969). With this kind of background the nationalists got the political independence for Nigeria. This political backdrop created misgivings, mistrust and pitted the major ethnic groups against themselves. There was no national cohesion among the doyen of Nigerian nationalists who took over from the departing colonial overlords became disillusioned about International Journal of Humanities and Social Sciences (IJHSS) ISSN(P): 2319-393X; ISSN(E): 2319-3948 Vol. 4, Issue 5, Aug - Sep 2015, 35-42 © IASET
