Military Intervention in Nigerian Politics: Historical Patterns and Democratic Implications

This study analyses historical patterns of military intervention in Nigerian politics from independence in 1960 to the return to civilian rule in 1999, assessing the long-term implications of military rule for democratic consolidation. Nigeria experienced a series of military coups and extended periods of authoritarian governance that disrupted institutional development, weakened civil society, and cultivated a political culture of impunity. Using a historical-descriptive research design, the study draws on archival materials, published memoirs of military leaders, and scholarly analyses of Nigerian political history to reconstruct the conditions under which each military intervention occurred and evaluate its consequences for governance. The praetorian state theory and civil-military relations frameworks are employed to analyse the structural and institutional factors that made Nigeria susceptible to military takeovers. Findings reveal that military interventions were typically preceded by widespread perceptions of civilian governmental failure, ethnic tensions, and economic mismanagement, with the military presenting itself as a corrective force. However, successive military regimes deepened rather than resolved these structural problems, suppressed political pluralism, and bequeathed a legacy of institutional weakness to the Fourth Republic. The study concludes that while the formal return to civilian rule has stabilised, many informal norms associated with military governance continue to influence Nigerian political behaviour and institutional design. Recommendations include sustained investment in democratic education, judicial independence, and civilian oversight of the armed forces.
