Abstract
This study examines the impact of military regimes on Nigeria's foreign policy from 1966 to 1999, a period marked by multiple coups and military governance. It analyzes how successive military administrations, from General Aguiyi-Ironsi to General Abdulsalami Abubakar, shaped Nigeria's international relations, focusing on their adherence to or deviation from the foreign policy principles established at independence in 1960. The paper highlights the dynamic approaches of military leaders, particularly in promoting African unity, decolonization, and regional stability through initiatives like the Economic Community of West African States (ECOWAS) and support for liberation movements in Southern Africa. It contrasts the assertive and sometimes radical policies of military regimes with the more conciliatory civilian approaches, emphasizing the role of oil wealth in enabling bold diplomatic strides. Despite challenges, such as Nigeria's pariah status under General Sani Abacha, the military's contributions to anti-colonialism and regional peacekeeping were significant. The study concludes that military regimes, while often dictatorial, played a pivotal role in enhancing Nigeria's international influence, particularly in African affairs.
