Nigeria Constitution From Inception Till Date
Nigeria Constitution, Constitution of Nigeria

The Nigeria Constitution is the supreme legal document that outlines the structure of government, rights of citizens, and the powers and responsibilities of institutions in Nigeria.
The history of Nigeria’s constitutional development reflects its evolution as a nation, from pre-colonial indigenous governance systems through colonial administration, to post-independence adjustments. The Nigerian Constitution has served as the foundational legal framework for governance, that outlines the structure of government, the rights and responsibilities of citizens, and the distribution of powers.
Pre-Colonial Governance
Before the advent of colonial rule, Nigeria was home to diverse ethnic groups with distinct governance structures. These systems included the centralized empires of the Hausa-Fulani in the north, the Yoruba kingdoms in the west, and the decentralized Igbo communities in the east. Governance was typically based on customs, traditions, and unwritten laws tailored to local needs. While these systems varied significantly, they were largely cohesive and reflective of the social, economic, and cultural fabric of their respective societies.

Colonial Era and the First Constitution (1861-1946)

The Clifford Constitution (1922)
The Clifford Constitution marked the first major step in constitutional development. Introduced by Governor Sir Hugh Clifford, it replaced the 1914 amalgamation framework that unified the Northern and Southern Protectorates. Key features included:
- The establishment of a Legislative Council for the Southern Provinces.
- Limited representation, with four elected seats for Lagos and Calabar.

The Clifford Constitution laid the groundwork for political engagement, as evidenced by the formation of political groups such as the Nigerian National Democratic Party (NNDP).
The Richards Constitution (1946)
The constitiution was approved in 1946 and was called the Richards Constitution after Governor-General Sir Arthur Richards, who was responsible for its formulation. The Richards Constitution was introduced to address criticisms of the Clifford framework. It sought to promote greater participation by Nigerians and regional autonomy. Key elements included:
- Regional Councils for the North, West, and East.
- A central legislative council to address national issues.
- Inclusion of traditional rulers and elites in governance.
The Richards Constitution acknowledged Nigeria’s diversity by implementing a federal system with regional powers. While it accurately reflected the country’s circumstances, it ultimately reinforced regionalism rather than fostering political unity. It was abolished in 1950 in response to demands for increased autonomy. However, the Richards Constitution was criticized for its lack of widespread consultation and limited electoral representation.
