In the late 1950s, Nigeria stood on the edge of transformation. British colonial rule was drawing to a close, and three dominant political parties emerged, each deeply rooted in ethnic and regional identities:

- NCNC (National Council of Nigeria and the Cameroons) – Led by Dr. Nnamdi Azikiwe, representing the Eastern Region and predominantly the Igbo people.
- NPC (Northern People’s Congress) – Headed by Sir Ahmadu Bello, dominant in the Hausa-Fulani North.
- Action Group (AG) – Led by Chief Obafemi Awolowo, advocating for the Yoruba-speaking Western Region.
The 1959 federal elections produced no clear winner, prompting a coalition between the NPC and NCNC. On October 1, 1960, Nigeria officially gained independence. Abubakar Tafawa Balewa became Prime Minister, while Azikiwe served as Governor-General, in a British-style parliamentary system.

Republic Status & Rising Political Tensions
But beneath the surface, tensions simmered.
A controversial 1963 census stirred ethnic rivalries. The Igbo population believed the numbers had been manipulated to give the North an unfair majority in Parliament. Political alliances crumbled, and new coalitions emerged:
- UPGA (United Progressive Grand Alliance) – A partnership between the NCNC and a splinter faction of the AG.
- NNDP (Nigerian National Democratic Party) – Formed by the NPC and Ladoke Akintola’s faction of the AG.
Amid this political unrest, Nigeria found a rare moment of national pride when Nojim Mayegun won the country’s first Olympic medal—a boxing bronze at the 1964 Tokyo Games.
January 1966: Nigeria’s First Military Coup
On January 15, 1966, Nigeria experienced its first major political crisis. A coup, led by mainly Igbo officers, saw the assassination of Prime Minister Tafawa Balewa, Premier Ahmadu Bello, Premier Ladoke Akintola, and other top officials. President Azikiwe was abroad at the time.
Major General Johnson Aguiyi-Ironsi emerged as Head of State. He promised reform, anti-corruption measures, and a return to civilian governance. However, his Decree No. 34 abolished the federal system in favor of a centralized government—fueling suspicion among non-Igbo groups. Northern leaders were especially alarmed that coup plotters were not prosecuted.
July 1966: Retaliation and the Second Coup
In July 1966, northern officers carried out a counter-coup, assassinating Aguiyi-Ironsi and other Igbo military officials. The military chose Lieutenant Colonel Yakubu Gowon, a Christian from the Middle Belt, as Head of State. Although he had no direct role in the coup, Gowon was seen as a neutral figure capable of uniting the fractured nation.
Gowon worked quickly to ease tensions: restoring federalism, freeing political detainees like Obafemi Awolowo, and promising a return to democracy.
The Breaking Point: Biafra and the Lead-Up to War
In 1967, Gowon announced a restructuring of Nigeria—from four regions to twelve states. The move was seen by some as an attempt to weaken Eastern Region autonomy. The Eastern Region’s military governor, Colonel Chukwuemeka Odumegwu Ojukwu, rejected the new structure.
On May 30, 1967, Ojukwu declared the independence of the Republic of Biafra—a bold move that would trigger a full-scale civil war and leave a lasting scar on the nation’s history.
