The 1966 Nigerian coup d'état began on 15 January 1966, when mutinous Nigerian soldiers led by Chukwuma Kaduna Nzeogwu and Emmanuel Ifeajuna killed 22 people[1] including the Prime Minister of Nigeria, many senior politicians, many senior Army officers (including their wives), and sentinels on protective duty.[2][3] The coup plotters attacked the cities of Kaduna, Ibadan, and Lagos while also blockading the Niger and Benue River within a two-day span of time before the coup plotters were subdued. The General Officer Commanding, of the Nigerian Army, Johnson Aguiyi-Ironsi then used the coup as a pretext to annex power, ending Nigeria's nascent democracy. It was one of the events that led to the Nigerian Civil War.

In August 1965 a group of Army majors (Emmanuel Ifeajuna, Timothy Onwuatuegwu, Chris Anuforo, Don Okafor, Humphrey Chukwuka, and Adewale Ademoyega) began plotting a coup d'état against incumbent Prime Minister Abubakar Balewa. The coup was planned because according to the majors, the men at the helm of affairs were running Nigeria aground with their corrupt ways. Ministers under them were living flamboyant lifestyles and looting public funds at the expense of ordinary citizens.

The president of Nigeria, Nnamdi Azikiwe left the country in late 1965, first for Europe, then on a cruise to the Caribbean. Under the law, the Senate president, Nwafor Orizu, became acting president during his absence and had all the powers of the president.


Late in the morning of 15 January 1966, at a meeting with some local journalists in Kaduna seeking to find out what was going on, it was brought to Major Nzeogwu's attention that the only information about the events then was what was being broadcast by the BBC. Nzeogwu was surprised because he had expected a radio broadcast of the rebels from Lagos. He is said to have "gone wild" when he learnt that Emmanuel Ifeajuna in Lagos had not made any plans whatsoever to neutralize Johnson Aguiyi-Ironsi who was the Commander of the Army. Therefore, Nzeogwu hurriedly drafted a speech which was broadcast on Radio Kaduna sometime around 12 a.m. and in which he declared martial law over the Northern Provinces of Nigeria.[4][5]


Acting President Nwafor Orizu made a nationwide broadcast, after he had briefed President Nnamdi Azikiwe on the phone about the decision of the cabinet, announcing the cabinet's "voluntary" decision to transfer power to the armed forces. Major General Johnson Aguiyi-Ironsi then made his own broadcast, accepting the "invitation". On 17 January, Major General Ironsi established the Supreme Military Council in Lagos and effectively suspended the constitution.[6]
