The Nigerian Civil War, also known as the Biafran War and the Nigerian-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 Biafran 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.
