The immediate cause of the 1966 military coup de'etat in Nigeria was political instability. At the time, the country was facing a lot of challenges such as ethnic tensions, regionalism, and a struggle for power among the political elite. There was also a perception that the government was corrupt and ineffective in addressing the country's problems. These issues created a tense and unstable environment that eventually led to the coup. The military, led by Major Chukwuma Nzeogwu, overthrew the government of Prime Minister Sir Abubakar Tafawa Balewa on January 15, 1966.
