On 15 January 1966, a crisis-bound Nigerian government was overthrown by a swift military coup d'état. The Prime Minister of the Federal Republic and his powerful associate, the Federal Minister of Finance, were seized by soldiers in Lagos. Neither survived, although the death of the Prime Minister, who was not personally unpopular, may not have been premeditated. His political chief, the premier of the vast Northern Region, was killed in Kaduna, and the latter's ally, the premier of the Western Region, died violently in Ibadan. Their major opponents among Nigerian office holders, namely the President of the Republic and the premiers of the Eastern and Midwestern Regions, escaped death. The President was on leave outside the country; it is not clear whether the two surviving premiers were spared by design or mistake. In any case, the tendency in Nigerian politics with which the survivors had been identified did appear to have triumphed despite their personal losses of power.
