Event Summary

On 15 January 1966 rebellious soldiers led by Major Chukwuma Kaduna Nzeogwu and a group of army majors ("the January Boys," including Emmanuel Ifeajuna) carried out a putsch that killed 22 people, among them Prime Minister Abubakar Tafawa Balewa. Major General Johnson Aguiyi-Ironsi then accepted the transfer of power and, on 17 January, established the Supreme Military Council and suspended the constitution.
