Biafra
Between 1967 and 1970, there was a country in West Africa called Biafra. The unrecognised state seceded from Nigeria due to a variety of issues, among them politics and economic issues. Within six months of the existence of the newly independent state, the tide was already in favour of Nigeria, which had started blocking access to and from the region. It is reported that at least one million civilians died in the Biafra- Nigeria war due to hunger and starvation.
Biafra was reintegrated into Nigeria and cover the states of Anambra, Imo, Cross River and Rivers.
