Military coups in Nigeria

There have been a large number of successful and failed military coups in Nigeria since the country's independence from the British Empire in 1960. A military coup is the violent or non-violent overthrow of an existing political regime by the military. Between 1966 and 1999 the army held power in Nigeria without interruption apart from a short-lived return to democracy between 1979-1983. “Military coups and military rule (which began as an emergency aberration) became a seemingly permanent feature of Nigerian politics.

The January 1966 coup was carried out by mostly Igbo army officers including Major Kaduna Nzeogwu, Major Emmanuel Ifeajuna among others. The casualties of the coup included the Prime Minister Alhaji Abubakar Tafawa Balewa, the Sardauna of Sokoto Sir Ahmadu Bello, the Premier of the Western Region Samuel Akintola, the finance minister Festus Okotie-Eboh among others.

Popularly known as the Nigerian Counter-Coup of 1966, in July, saw Major-General Gowon succeed Ironsi. It lasted from July 28 to July 30th1966.

General Yakubu Gowon was ousted in a palace coup on July 30, 1975, which brought then Brigadier [Murtala Muhammed] to power as Head of State.

Popularly and erroneously known as the 'Dimka Coup', this bloody and aborted coup led to the assassination of General Murtala Muhammed. Upon General Muhammed's death and the foiling of the coup, then Lt General Olusegun Obasanjo became Head of State.

The Nigerian Military Coup of December 31, 1983 was led by a group of senior army officers who overthrew the democratically elected government of President Shehu Shagari. Participants included Majors General Ibrahim Babangida and Muhammadu Buhari, Brigadiers Ibrahim Bako, Sani Abacha, and Tunde Idiagbon. Major General Buhari was appointed Head of State by the conspirators.
