Blockade of Biafra

The blockade of Biafra by the Nigerian federal government during the Nigerian Civil War (1967–1970) resulted in a famine that ultimately cost at least a million lives and ended with the capitulation of the secessionist state of Biafra.
The blockade and the ensuing humanitarian crisis stimulated worldwide mobilization and widespread debate about the concept of genocide. It also stimulated widespread debate about whether or not it was appropriate to describe the events which occurred in Biafra as a genocide. Ultimately, it contributed to reform in the law of blockade to protect civilians and the prohibition of starvation as a method of warfare in the 1977 amendments to the Geneva Conventions.
In the aftermath of the 1966 Nigerian counter-coup, anti-Igbo pogroms erupted across northern Nigeria, killing thousands of Igbos. Chukwuemeka Odumegwu Ojukwu declared the independence of Biafra in the Igbo-populated areas of Nigeria in 1967, and the federal government led by Yakubu Gowon launched a civil war against the secessionist entity.
During the first weeks of the war, the Nigerian government decided to impose a blockade of Biafra. Access to the secessionist republic through foreign currency transactions, mail and telecommunications, and all seaports and airfields was to be cut off. Initially it was unclear whether the blockade of the 200 miles (320 km) coast would be effective with the ships available to the Nigerian Navy, and whether the Nigerian Air Force would be able to interdict the air routes. Nevertheless, the blockade was effective and maintained for the next two and a half years. The Nigerian government relied on international law to enforce the blockade, since at the time starvation as a weapon of war was not prohibited and all neutral countries were obliged to abide by an announced blockade. The Nigerian government threatened reactions against countries that disregarded the blockade and made an agreement with Cameroon to obstruct Biafra's land border. Some smugglers attempted blockade running but two ships were destroyed by the Nigerian navy.
The blockade interdicted food, medicine, and other supplies needed by civilians. Nigerian federal leaders obstructed the passage of relief supplies and stated that starvation was a deliberate tactic of war, although also dismissing reports of famine as Biafran propaganda.
The Biafran government rejected daylight aid flights and a proposed aid corridor. Its leader Ojukwu argued that these routes would allow the Nigerian government to poison Biafrans and enable the bombing of Biafra. However, another reason was to preserve the clandestine routes from which Biafra continued to import arms and ammunition. It is estimated that one million or more people died as a result of the blockade. Most of the war casualties were civilians particularly children, who were especially vulnerable to malnutrition.
Another consequence of the blockade was a rise in violent crime in Biafra, particularly violent extraction of food from civilians by underfed soldiers in the Biafran army.
Biafra attracted a large amount of international attention from mid-1968, when images of starving Biafran children began to appear in the international press. Biafran propaganda compared Igbo to Jews and the blockade of Biafra to the Holocaust. Initially, international public opinion was sympathetic to Biafran claims, but shifted after the United Kingdom sent a fact finding mission to Nigeria that reported that genocide was not occurring. Some scholars who had initially believed that there was a genocide in Biafra, such as Robert Melson, changed their opinion after realizing that the Nigerian government did not plan to kill all Igbos, and because the reasons for their death were political rather than racial.
The largest organization in the United States that formed in reaction to the Biafra war was the American Committee to Keep Biafra Alive. In West Germany the war resulted in an unprecedented mobilization and the amount of money raised, 70 million marks, exceeded that previously raised for any humanitarian cause. Some relief organizations, including the ICRC, only operated with the permission of both belligerents, limiting relief efforts.
Relief efforts were cut off in June 1969 when a Swedish Red Cross plane was shot down by Nigerian government forces.
Soon after the civil war ended in 1970, it was largely forgotten outside Nigeria and not much mentioned in the field of genocide studies. The ICRC recognized that the failure of its relief effort was due in part to the blockade law endorsed by the Western powers, and increased its efforts to secure stronger legal protections for civilians. According to the 1977 Protocol II, "objects indispensable to the survival of the civilian population" are protected and attacks against them are prohibited.
In Nigeria, the blockade and its casualties were ignored in official commemorations and school curricula. In 2021, President of Nigeria Muhammadu Buhari made tweets alluding to the war, which were deleted for promoting violence; subsequently, Twitter was banned in Nigeria.
Cohort studies suggest that the famine had long-term health impact on survivors.
