Q: The Nigerian Civil War, commonly known as the Biafran War (6 July 1967 -- 15 January 1970), was a war fought between the government of Nigeria and the secessionist state of Biafra. Biafra represented nationalist aspirations of the Igbo people, whose leadership felt they could no longer coexist with the Northern-dominated federal government. The conflict resulted from political, economic, ethnic, cultural and religious tensions which preceded Britain's formal decolonisation of Nigeria from 1960 to 1963. Immediate causes of the war in 1966 included a military coup, a counter-coup and persecution of Igbo living in Northern Nigeria. Control over oil production in the Niger Delta played a vital strategic role.
