Murtala Muhammed (8 November 1938 – 13 February 1976) was a Nigerian general who led the Northern counter-coup forces in overthrowing the Republic of Nigeria and featured prominently during the Nigerian Civil War and thereafter ruled over Nigeria from 30 July 1975 until his assassination on 13 February 1976. This period in Nigerian history, from the Northern counter-coup victory to Murtala's death, is commonly associated with the institutionalization of the military in politics.

Born in Kano, into a ruling-class religious family, Murtala served in the Nigerian Army as a cadet in the Royal Military Academy, Sandhurst. He later served in Congo; eventually rose through the ranks to become brigadier general in 1971, aged 33, becoming one of the youngest generals in Nigeria. Three years later Murtala became the Federal Commissioner for Communications in Lagos. As a conservative and federalist, Murtala regretted the overthrow of the First Republic and the promulgation of Aguiyi Ironsi's unification decree of 1966. He was devastated by the assassination of Sir Ahmadu Bello, and for a time seriously considered the secession of Northern Nigeria. His career redoubled after Chukwuma Kaduna Nzeogwu and the young majors orchestrated the first military coup in Nigeria of 1966 coup empowering him to lead the mutiny of the night of 29 July 1966 in Abeokuta. Murtala was briefly considered as Supreme Commander before the appointment of Yakubu Gowon. He also masterminded the July 1966 counter coup, which evidently, sparked the Nigerian Civil War.
