I was surprised to find that the first result I got when searching for information on the Biafran War was an article from American University. Looking over it helped quite a bit with my understanding of Half of a Yellow Sun. In essence, the war was started because of the highly differing tribes being forced together by British rule, though even after the “united” Nigeria gained independence from the British, the Igbo and other minority groups banded together in order to try to remove themselves from the country they’d been forced to be a part of. This was something that the Hausa disagreed with, since the Igbo controlled the Niger Delta and its oil supply, which made up the majority of Nigeria’s economy. The war lasted from 1967-1970 and, though there were 100,000 military deaths, there were 500,000 to 2 million dead from starvation in the war’s aftereffects.
Biafra was made a republic on May 30, 1967. However, most countries, including other African countries, refused to acknowledge it. Only Tanzania, Zambia, Gabon, South Africa, and the Ivory Coast were the only ones to do so. Eventually, however, Nigeria was separated into 12 different states and Biafra was reabsorbed into the Eastern Central State in April of 1968. Two years late, Nigeria finally regained peace.
