Nigeria became a federation as a result of the promulgation of the constitution of 1954. This was the Macpherson Constitution, which replaced the Richards Constitution of 1946. The new constitution introduced a federal system of government in Nigeria, which allowed for greater autonomy and power for the regions. Under the new constitution, Nigeria was divided into three regions: Northern Region, Eastern Region, and Western Region, each with its own government and legislature. The federal government was responsible for issues that affected the whole country, such as defense, foreign affairs, and monetary policy.
