The Nigerian Civil War (1967-1970)
The secession of Nigeria's Eastern Region as the Republic of Biafra produced a two-and-a-half-year civil war whose defining image became the famine caused by the federal blockade. Between one and three million people, most of them children, died before Biafra's surrender, and the conflict reshaped humanitarian doctrine, postcolonial sovereignty norms, and Nigerian politics.
Events
The January 1966 Coup
A group of mostly Igbo junior officers led by Major Kaduna Nzeogwu seized power in Nigeria's first military coup, killing the prime minister and several regional premiers and top officers. The coup collapsed in the north and west, and General Johnson Aguiyi-Ironsi, the most senior officer, took power as head of a military government.
Location: Lagos, Nigeria
Counter-Coup and Anti-Igbo Pogroms
A counter-coup in July killed General Ironsi and brought General Yakubu Gowon to power. Over the following months, waves of violence against Igbo residents in the north killed tens of thousands, and roughly a million Igbos fled eastward, giving the Eastern Region's governor, Lieutenant Colonel Odumegwu Ojukwu, a displaced population and a case for self-protection.

The Aburi Accord Fails
At a meeting in Aburi, Ghana, brokered by Ghana's leadership, Gowon and Ojukwu agreed on principles for a confederal restructuring to hold Nigeria together. Divergent interpretations of the accord collapsed on their return, with the federal government insisting on a stronger center and the east insisting on the loose arrangement it had heard agreed.

State Creation and the Biafran Declaration
Gowon preempted secessionist pressure by dividing Nigeria's four regions into twelve states on May 27, cutting the Eastern Region into three; the region's oil revenues were at the center of the dispute. Three days later Ojukwu declared the Eastern Region the independent Republic of Biafra, citing the pogroms and the failure of the accords.

War Begins and the Midwest Advance
Federal troops crossed into Biafra in early July, beginning the war; Biafran forces counterattacked and briefly overran the Midwestern Region in August. The federal counteroffensive by October pushed Biafran forces back and captured key eastern towns, progressively encircling the enclave.

The Fall of Port Harcourt and the Blockade
Federal forces captured Port Harcourt, completing the land blockade of Biafra and closing the enclave's access to the sea for food and arms. The Nigerian government defended the blockade as a legitimate war measure to end secession quickly; critics, then and since, argued it weaponized starvation against the civilian population.

The Famine and the Airlift
As food supplies collapsed, images of Biafran children suffering kwashiorkor famine spread through the world's media, sparking one of the first global humanitarian campaigns. Church groups operated a massive night airlift into the Uli airstrip, while France and other states quietly favored Biafra and Britain and the Soviet Union armed Nigeria, making the war a proxy front of the Cold War.

Biafra's Final Collapse
With the enclave reduced to a fraction of its original territory and the airlift halted, Ojukwu flew into exile in Ivory Coast, leaving command to his deputy Philip Effiong. Biafra formally surrendered on January 15, 1970, ending the war with Nigeria's reunification.
Location: Uli, Biafra
Reconciliation and Its Aftermath
Gowon declared there would be no victor and no vanquished, and pursued a program of reconstruction, rehabilitation, and reconciliation that reintegrated Biafran officers and civil servants without trials. Estimated deaths from the war and famine, most of them civilians, range from one to three million, and the conflict's lessons reshaped the International Committee of the Red Cross's doctrine on starvation as a method of warfare.
