The Dynamics of the Evolution of Nigeria as a Political Unit
Amalgamation and Early Colonial Administration
In , Sir Frederick (later Lord) Lugard amalgamated Northern and Southern Nigeria primarily to address the North's financial deficit, as the Northern Protectorate required an annual subsidy of about and over million in loans from the south. British colonial policy was largely divisive, keeping the two protectorates separate and limiting interaction between the north and south. This isolationism was reinforced in when the Southern provinces were split into Eastern and Western Provinces while the Northern provinces remained intact, a tripartite structure that persisted until after independence.
Nationalist Struggle and Constitutional Frameworks
Nationalist agitations were spearheaded by figures such as Herbert Macaulay and Dr. Nnamdi Azikiwe, with groups like the Nigerian Youth Movement (NYM) and the National Council of Nigeria and the Camerouns (NCNC) leading the decolonization effort. The path to independence was paved with three major constitutions: the Richards Constitution, which established regional councils; the Macpherson's Constitution of , created after extensive consultations; and the Lyttleton Constitution of , which established the federal system. Political alignment was dominated by ethnic-based parties, including the Action Group Party (AG) and the Northern Peoples Congress (NPC), which often prioritized regional interests over national unity.

Nigeria experienced a series of military regimes following General Yakubu Gowon's ousting in , including those led by General Murtala Mohammed and Lt. General Olusegun Obasanjo. After a brief return to civilian rule under Alhaji Shehu Shagari (-), the military returned to power under Major General Muhammadu Buhari and later General Ibrahim Babangida, the latter of whom annulled the June , election perceived to be won by Chief Moshood Abiola.

Nigeria's Standing in the International Arena
Nigeria's foreign policy has focused on Africa as its "centre-piece," participating in organizations like the United Nations Organisation (U.N.O.), the Organisation of African Unity (O.A.U.), and the Economic Community of West African States (ECOWAS). The country played a commendable role in the decolonization of Zimbabwe, Angola, Mozambique, Namibia, and South Africa, and led peacekeeping efforts in the Congo, Yugoslavia, and Chad.
