The Nigerian Civil War, also known as the Biafran War, 6 July 1967 – 15 January 1970, was a war fought to counter the secession of Biafra from Nigeria. 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 decolonization 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.
