Federalism was introduced in Nigeria under the Richards Constitution.
Federalism is a political system in which power is divided between a central government and individual states or regions. In Nigeria, this system of government was first introduced under the Richards Constitution in 1954, which established a federal system of government in the country. This constitution created a central government responsible for certain areas of governance, such as foreign affairs and defense, while giving individual states the power to govern themselves in other areas. This division of power between the central government and individual states continues to be a defining feature of the Nigerian political system today.
