On July 29, 1975 a group of Nigerian officers overthrew General Yakubu Gowon in a bloodless coup while he was out of the country at an Organisation of African Unity summit, installing Brigadier Murtala Mohammed as head of state. Gowon had ruled Nigeria since the 1966 counter-coup and had led the federal side to victory in the Biafran civil war, but by 1975 he had lost support: he had reneged on a promise to return the country to civilian rule by 1976, and his government was seen as tainted by corruption and drift amid the oil boom. While Gowon attended the twelfth OAU summit in Kampala, Uganda, a faction of officers acted; Ugandan president Idi Amin reportedly passed Gowon a note informing him he had been overthrown.
Colonel Joseph Garba, a Gowon confidant and commander of the guards, announced the coup on Radio Nigeria, and the plotters named Brigadier Murtala Mohammed head of state with Brigadier Olusegun Obasanjo as his deputy. Gowon accepted the outcome, was assured of his safety and benefits, and went into exile in Britain.

The 1975 Nigerian coup was a bloodless military coup on 29 July 1975 when a faction of junior Armed Forces officers overthrew General Yakubu Gowon, who at the time was attending the 12th Organisation of African Unity summit in Kampala, Uganda, and the plotters appointed Brigadier Murtala Mohammed as head of state and Brigadier Olusegun Obasanjo as his deputy.
The coup was motivated by unhappiness of junior officers at the lack of progress Gowon had made in moving the country towards democratic rule, while Colonel Joseph Nanven Garba announced the coup on Radio Nigeria, and Garba's role as an insider is credited with ensuring the coup was bloodless.
The coup occurred while Gowon was attending the OAU summit, where Ugandan President Idi Amin quietly passed him a note informing him he had been overthrown, and Gowon accepted the coup without resistance, later receiving assurances of his personal safety and full retirement benefits from the new regime.
Colonel Joseph Nanven Garba, commander of the Brigade of Guards and a close friend of Gowon, announced the ouster citing frustration with Gowon's indefinite postponement of the return to civilian rule promised since 1966 and widespread corruption amid the oil boom, and Mohammed was proclaimed Head of State on July 30, 1975.
Fate coding: Gowon was overthrown while abroad, not physically harmed, and went into exile in Britain (where he later earned a doctorate), matching the dataset's exiled fate. Coding note: the dataset labels this a military coup; it was a bloodless palace coup executed while the head of state was out of the country, eased by the participation of his own guards commander. Arc link: Gowon had himself come to power in the July 1966 counter-coup (a distinct earlier dataset event); this 1975 coup ended his nine-year rule. Arc forward: Murtala Mohammed was assassinated in a failed coup on February 13, 1976, after which his deputy Obasanjo became head of state and later oversaw the 1979 return to civilian rule, separate later events.
