The main legislative body in Nigeria between 1966 and 1975 was not a civilian body, but rather a military council called the Supreme Military Council (SMC). The SMC was established after a series of military coups in Nigeria in 1966 that overthrew the civilian government. The SMC was made up of senior military officers, led by the head of state, and had the power to make laws and policies for the country. During its tenure, the SMC ruled by decree, bypassing the normal legislative process. The SMC remained the main legislative body in Nigeria until 1975, when it was replaced by the Armed Forces Ruling Council (AFRC), which continued to rule the country until 1979. In summary, the main legislative body in Nigeria between 1966 and 1975 was the Supreme Military Council, which was a military council made up of senior officers that ruled the country by decree after a series of military coups in Nigeria.
