Overview
The Nigerian Civil War (1967–1970) began when the predominantly Igbo eastern region of Nigeria declared independence as the Republic of Biafra. The federal government's military response included a blockade that caused one of the 20th century's most visible famines — images of starving Biafran children shocked the world. An estimated 1–3 million people died, the majority from starvation.

Full History
The Nigerian Civil War emerged from the ethnic and political tensions that followed Nigerian independence from Britain in 1960. Nigeria's colonial borders had lumped together hundreds of ethnic groups, with three dominant ones: the Hausa-Fulani (predominantly Muslim, dominant in the north), the Yoruba (southwest), and the Igbo (southeast). After two military coups in 1966 — the second specifically targeting Igbo officers — and a wave of anti-Igbo pogroms in the north that killed 10,000–30,000 people and displaced over a million, the military governor of the Eastern Region, Odumegwu Ojukwu, declared independence as the Republic of Biafra on May 30, 1967.
The federal government, led by General Yakubu Gowon, declared war to preserve Nigerian unity. What followed was a brutal three-year conflict in which federal forces, backed by the Soviet Union and Britain, gradually encircled and compressed the secessionist territory. Military operations were accompanied by a naval blockade cutting off Biafra from food and medical supplies — a strategic choice that would produce one of the century's defining humanitarian catastrophes.
The famine that resulted from the blockade became the most televised in history to that point. Red Cross and aid organizations documented Igbo children with the distended bellies and orange-tinted hair of kwashiorkor — severe protein deficiency. Photographs and film footage circulated globally, generating massive international pressure for humanitarian access. The Irish charity CONCERN was founded specifically in response to the Biafra crisis; it was also a formative event for Médecins Sans Frontières (MSF), whose founders broke from the Red Cross over the question of whether to speak publicly about atrocities witnessed.
Estimates of total deaths range from 1 to 3 million, with the majority dying from starvation and related disease rather than combat. Airlift operations — flown at night to evade federal aircraft — brought in some food and medicine but were wholly insufficient. Biafra surrendered on January 15, 1970. Despite dire predictions, the post-war period was notable for a relatively conciliatory "No victor, no vanquished" policy by Gowon, and Nigeria avoided the worst post-war reprisals — though full political reconciliation has remained incomplete.

Frequently Asked Questions
How many people died in the Biafran War?
Estimates range from 1 to 3 million deaths, with approximately 2 million being the most cited figure. The crucial fact is that the great majority — perhaps 90% — died from starvation and disease caused by the federal blockade, not from combat. The famine killed approximately 8,000–10,000 people per day at its peak in 1968–69.
Why did Biafra secede?
Following two military coups in 1966 and organized massacres of Igbo people in northern Nigeria (killing 10,000–30,000), the Igbo-dominated Eastern Region felt it had no future within Nigeria. Governor Ojukwu declared independence as Biafra on May 30, 1967, with the backing of most Igbo people who feared genocide if they remained within the federation.
Who supported each side?
The federal Nigerian government was backed by the Soviet Union (weapons) and Britain (political and material support). Biafra received covert support from France (weapons through Côte d'Ivoire and Gabon) and some humanitarian support from international NGOs. The US officially remained neutral but tacitly backed the federal government. Many African states supported Nigeria's territorial integrity.
What was the long-term impact of the Biafra war?
The war shaped modern humanitarian intervention: it catalyzed the founding of Médecins Sans Frontières (MSF) and strengthened Red Cross humanitarian law. Within Nigeria, the war created ethnic tensions that persist today, with periodic calls for Biafran independence. Economically, the discovery of oil in the Niger Delta — in former Biafran territory — has remained a source of conflict and grievance.
Sources
Death toll is heavily debated. The range 1–3M reflects genuine uncertainty; most deaths were from famine with no reliable enumeration. The 2M figure is widely cited but contested. Igbo nationalist sources tend toward higher estimates; Nigerian federal sources lower.
