Abstract
Nigeria gained her independence in October 1960 after almost six decades of British colonial rule. The country’s journey into nationhood was herald by high hopes and prospects for national unity, peace and development. This was because of its vast human and material resources, and land mass. Nigeria is dominantly made of three prominent regions: the North (Hausa Fulani), the West (Yorubas) and the East (Igbos) with minorities in other regions.The military took over the leadership of the country barely six years into her independence as a nation. The military held sway for twenty nine years out of the ininitial forty years of the country’s post independence history before her return to civil rule in 1999.The county is still been confronted with challenges on all fronts ranging from insecurity and insurgency, economy, political uncertainty, electoral malpractices, high rate of unemployment, poor infrastructure amongst others. Literature have been skewed toward military intervention in politics as the root cause of the challenges bedeviling the country more than two decades after her return to civil rule.The study employed both quantitative and qualitative data. The study analysed the history of military rule in Nigeria and interrogated the crux of the military institution. It further analysed the peculiarities of each of the military regimes. The study also examined the post-military era in the country and concluded with recommendations.
