A coup was launched on 16 January 1966 by a group of disaffected young military officers led by Major Chukwuma Kaduna Nzeogwu. The army quickly suppressed the revolt but assumed power when it was evident that key politicians had been eliminated, including Prime Minister Abubakar Tafawa Balewa, Premier of Northern Region Sir Ahmadu Bello and Premier of the Western Region, Chief Samuel Ladoke Akintola.
