The
1966 Nigerian coup d'état began on January 15, 1966 when mutinous Nigerian soldiers led by
Kaduna Nzeogwu assassinated 11 senior Nigerian politicians and two soldiers as well as kidnapping three others. 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. A senior Army officer, General
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.
