Nigerian Civil War 1967-1970: The Biafra Secession and Famine
The Nigerian Civil War (1967-1970) followed Biafra's secession from Nigeria. Its causes, the fighting, the blockade and famine, and how Nigeria was reunited.

Contents
The Nigerian Civil War, also called the Biafran War, was fought from 6 July 1967 to 15 January 1970 between the federal government of Nigeria and the secessionist Republic of Biafra in the country’s southeast. The conflict became notorious for the famine caused by the blockade of Biafra, which killed hundreds of thousands of civilians and prompted one of the largest humanitarian relief efforts of the 20th century.
Background
Nigeria became independent from Britain on 1 October 1960, during the Year of Africa. It was a federation of large regions, each dominated by one major group: the Hausa-Fulani in the North, the Yoruba in the West and the Igbo in the East. Rivalry over power, census results and elections strained the young state. Disputed elections in the Western Region in 1965 led to widespread violence, and many Nigerians lost faith in the civilian politicians of the First Republic.
On 15 January 1966 a group of mostly Igbo junior officers staged a coup in which the federal prime minister Abubakar Tafawa Balewa and the premiers of the Northern and Western regions were killed. The army commander, Major General Johnson Aguiyi-Ironsi, an Igbo, took power. Many northerners saw the coup as an Igbo plot, and Ironsi’s decree abolishing the federal regions in May 1966 increased their fears.
On 29 July 1966 northern officers staged a counter-coup, killing Ironsi, and Lieutenant Colonel Yakubu Gowon became head of state. During 1966 thousands of Igbo and other easterners living in the North were killed in massacres, with estimates ranging from several thousand to around 30,000. Up to a million or more fled back to the Eastern Region.
Secession
The military governor of the East, Lieutenant Colonel Chukwuemeka Odumegwu Ojukwu, refused to accept Gowon’s authority. Talks at Aburi in Ghana in January 1967 produced an agreement that each side interpreted differently. On 27 May 1967 Gowon divided Nigeria into 12 states, cutting the oil-rich minority areas away from the Igbo heartland.
Three days later, on 30 May 1967, Ojukwu proclaimed the independent Republic of Biafra, named after the Bight of Biafra on the Atlantic coast. Fighting began on 6 July 1967, when federal troops advanced into the north of the new state in what the government initially described as a police action.
Course of the war
In August 1967 Biafran forces made a surprise thrust west into the Midwest Region, capturing Benin City and pushing towards Lagos before being halted near Ore. Federal troops recaptured Benin City in September. During the federal advance at Asaba in October 1967, soldiers killed hundreds of local men in a massacre long left out of official histories.
Federal forces had seized the oil terminal island of Bonny in July 1967, and took the Biafran capital, Enugu, in early October 1967. The capture of Port Harcourt in May 1968 cut Biafra off from the sea. Biafra’s territory shrank steadily, though its army fought on with determination and recaptured Owerri in April 1969. Umuahia, the later capital, fell in April 1969.
Biafra’s resistance owed much to improvisation. Its engineers built home-made weapons, including a powerful command-detonated mine known as the ogbunigwe, refined crude oil in small local plants and ran a skilled propaganda operation from Geneva that kept the war in Western newspapers. A small Biafran air arm of light aircraft, some flown by foreign volunteers, attacked federal airfields and oil installations in 1969. The federal army, meanwhile, expanded from around 10,000 men in 1966 to well over 200,000 by the end of the war.
Blockade and famine
The federal government imposed a land, sea and air blockade on Biafra. As territory shrank and refugees crowded into the enclave, food supplies collapsed. Protein deficiency, especially kwashiorkor among children, became widespread, and from mid-1968 photographs of starving children shocked audiences in Europe and North America.
Churches and humanitarian agencies, including the International Committee of the Red Cross and a coalition known as Joint Church Aid, flew night-time relief flights from the island of São Tomé and elsewhere into Uli, a stretch of road converted into an airstrip. The federal side argued that the blockade was a legitimate weapon of war and that relief flights also helped bring in arms.
Estimates of deaths remain uncertain. Most put civilian deaths at between about 500,000 and 2 million, the majority from starvation and disease. Biafra accused Nigeria of genocide, a charge investigated by international observers at the time and still debated.
International involvement
Britain, the former colonial power, and the Soviet Union supplied arms to the federal government. Biafra received covert aid from France and some support from Portugal and South Africa, and was formally recognised by only five states: Tanzania, Gabon, Côte d’Ivoire, Zambia and Haiti. The Organisation of African Unity backed Nigerian unity, partly from fear that secession would encourage similar movements across the continent, as had happened in the Congo Crisis.
In Britain, television images of the famine made the government’s arms supplies deeply controversial, and there were protests and parliamentary debates throughout 1968 and 1969. Several attempts at peace talks, in Kampala, Niamey and Addis Ababa, failed because Biafra insisted on sovereignty and the federal government on unity.
End of the war
A final federal offensive launched in December 1969, spearheaded by Colonel Olusegun Obasanjo’s 3rd Marine Commando Division, split the remaining enclave and took Owerri in early January 1970. On 11 January 1970 Ojukwu flew into exile in Côte d’Ivoire, leaving Major General Philip Effiong in charge. Effiong announced Biafra’s surrender, and its representatives formally signed it in Lagos on 15 January 1970.
Gowon declared a policy of “no victor, no vanquished” and launched a programme of reconciliation, rehabilitation and reconstruction. There were no mass reprisals of the kind many had feared. However, a rule that allowed former Biafrans to withdraw only £20 from their pre-war bank accounts, regardless of the balance, caused lasting resentment.
By the numbers
| Measure | Estimate (figures vary) |
|---|---|
| Duration | 6 July 1967 – 15 January 1970 |
| Civilian deaths, mostly from famine | About 500,000 – 2 million |
| States recognising Biafra | 5 |
| Easterners killed in 1966 massacres | Several thousand to about 30,000 |
Legacy
The war preserved Nigeria’s unity, and the country’s oil wealth grew rapidly in the 1970s. Memories of the conflict remain powerful among the Igbo, and calls for Biafran independence have resurfaced in recent decades. The war has been explored in literature, notably Chinua Achebe’s memoir “There Was a Country” and Chimamanda Ngozi Adichie’s novel “Half of a Yellow Sun”.
The Biafran crisis also changed humanitarian aid. French doctors who had served there with the Red Cross, including Bernard Kouchner, helped found Médecins Sans Frontières in 1971, arguing that aid workers should speak out about abuses instead of remaining silent.

Why it matters
The Nigerian Civil War was one of the deadliest conflicts in post-colonial Africa. It confirmed the principle that Africa’s colonial-era borders would be defended, made famine a central issue of global humanitarian concern and continues to shape Nigerian politics and identity.
Frequently asked questions
What caused the Nigerian Civil War?
The war grew out of ethnic and regional tensions after independence, two military coups in 1966 and massacres of Igbo people in northern Nigeria that year. After talks failed, the Eastern Region under Lieutenant Colonel Ojukwu declared itself the Republic of Biafra on 30 May 1967, and the federal government went to war to reunite the country.
How many people died in the Biafran War?
Estimates vary widely. Most put civilian deaths at between about 500,000 and 2 million, the majority from starvation and disease caused by the blockade of Biafra, in addition to tens of thousands of soldiers killed on both sides.
Who led Biafra?
Biafra was led by Chukwuemeka Odumegwu Ojukwu, the military governor of the Eastern Region, who proclaimed independence in May 1967. He fled into exile in January 1970, leaving his deputy Philip Effiong to announce Biafra's surrender.
Which countries recognised Biafra?
Only five states formally recognised Biafra: Tanzania, Gabon, Côte d'Ivoire, Zambia and Haiti. France, Portugal and others gave it covert support, while Britain and the Soviet Union armed the federal government.
How did the Nigerian Civil War end?
A final federal offensive in December 1969 and January 1970 broke Biafran resistance. Ojukwu left the country on 11 January, and Biafran representatives formally surrendered in Lagos on 15 January 1970; Gowon declared that there was 'no victor, no vanquished'.
