Republican Nigeria: A turning point in the nation’s history
Republican Nigeria refers to the period between 1963 and 1966, marking Nigeria’s transformation from a constitutional monarchy under British colonial rule to a fully sovereign republic. This short but pivotal era laid the groundwork for the country’s evolving political structure and national identity.
Transition from Monarchy to Republic
Following Nigeria’s independence in 1960, the country retained Queen Elizabeth II as the ceremonial head of state, represented locally by a Governor-General. However, on October 1, 1963, Nigeria adopted a republican constitution, removing the British monarch as head of state. Dr. Nnamdi Azikiwe, who had been Governor-General, became the country’s first President, a largely ceremonial role in the parliamentary system.

This transition was a major step toward full sovereignty, solidifying Nigeria’s break from its colonial past.
Political Structure
During Republican Nigeria, the country operated under the Westminster parliamentary system inherited from Britain. Sir Abubakar Tafawa Balewa remained Prime Minister, wielding executive power, while Nnamdi Azikiwe acted as head of state. Power was shared among the three major regions—the Northern, Western, and Eastern Regions—each with significant autonomy.

This era also witnessed growing ethno-regional tensions, with political parties such as the Northern People’s Congress (NPC), Action Group (AG), and National Council of Nigeria and the Cameroons (NCNC) often aligned along ethnic lines.
Crisis and Collapse
The Republican era was marred by political instability and ethnic rivalry, especially in the Western Region, where a crisis in the Action Group led to chaos and a breakdown of law and order. Tensions escalated across the country, culminating in the 1966 military coup led by Major Chukwuma Kaduna Nzeogwu, which ended the First Republic and ushered in a period of military rule.
Legacy
Though short-lived, Republican Nigeria was significant in asserting national independence, establishing indigenous control of governance, and revealing the challenges of managing a diverse, multi-ethnic state. The issues that plagued this period—such as regionalism, corruption, and weak democratic institutions—continue to inform debates in Nigeria’s Fourth Republic today.
