| The Biafran civil war was precipitated by an attempt by the Nigerian government to lessen the political power of certain Nigerian ethnic groups by dividing the country’s 4 existing regions into 12 states. The former Eastern Region declared itself independent in May 1967 as the Republic of Biafra, left, and the civil war ensued. By January 1970 the Biafran forces controlled only a small portion of Biafra, right, and surrendered. |
