When Nigeria adopted its Republican Constitution on 1 October 1963, it declared itself a republic within the Commonwealth, severing one of the last symbolic ties to British monarchical authority. Built upon the Westminster framework of the 1960 Independence Constitution, the 1963 document marked a decisive political milestone: Nigeria now had a Nigerian Head of State, a Supreme Court as its final court of appeal, and a federal system more clearly defined to reflect evolving regional realities.
Yet, the First Republic that operated under this constitution endured barely two and a half years before collapsing in the military coup of 15 January 1966. The rise and fall of the 1963 Constitution reveal the enduring tensions between sovereignty, federal balance, and political legitimacy in Nigeria’s early post-independence years.

The 1960 Independence Constitution and Its Limits
Nigeria achieved independence on 1 October 1960 under a constitution modelled on the British parliamentary system. Under that arrangement, Queen Elizabeth II remained the ceremonial Head of State, represented in Nigeria by a Governor-General. While the constitution granted Nigeria full control over internal affairs, many nationalists viewed the Queen’s role as a lingering vestige of colonial subordination.
The 1960 framework also left unresolved questions about the division of powers between the federal and regional governments. The three regions, Northern, Western, and Eastern, enjoyed wide autonomy, yet tensions persisted over revenue allocation, residual powers, and federal intervention. These issues exposed the limits of the Independence Constitution and spurred calls for a framework that would fully affirm Nigeria’s republican sovereignty.
Constitutional Reform and the Path to 1963
By early 1963, Nigeria’s regional premiers and the federal Prime Minister, Sir Abubakar Tafawa Balewa, began formal consultations to introduce a republican constitution. Parliamentary debates and an all-party constitutional conference later that year refined proposals on the presidency, judiciary, and federal balance.
The Republican Constitution Bill was passed by the Federal Parliament in September 1963 and came into effect on 1 October 1963, exactly three years after independence. In the same period, Nigeria’s fourth region, the Mid-Western Region, was created in August 1963 following a plebiscite in the Western Region, marking the first constitutional alteration of Nigeria’s internal boundaries.
Key Provisions of the 1963 Republican Constitution
A Nigerian Head of State: The Republican Presidency
The most visible reform was the replacement of the British monarch and Governor-General with a President of the Republic. The President was elected by a joint sitting of both houses of the National Assembly through a secret ballot and served as Commander-in-Chief of the Armed Forces. In practice, however, the office remained largely ceremonial, while executive authority rested with the Prime Minister and Cabinet, consistent with the Westminster model.
If the President died, resigned, or became incapacitated, the President of the Senate would act as Head of State for up to six months pending the election of a new President.
Retention of the Parliamentary Executive
Executive power continued to be exercised in the name of the President but only on the advice of the Prime Minister and Ministers. The Prime Minister’s tenure depended on maintaining the confidence of the House of Representatives, there was no fixed term. This arrangement preserved continuity with the 1960 system, where political accountability was grounded in parliamentary majority support.
Judicial Sovereignty and the Supreme Court
A defining assertion of sovereignty under the 1963 Constitution was the establishment of the Supreme Court of Nigeria as the final court of appeal, ending judicial recourse to the Judicial Committee of the Privy Council in London, except for cases already pending before it.
The Federal Judicial Service Commission that had existed under the 1960 Constitution was replaced with a revised advisory process: the President appointed judges on the advice of the Prime Minister, after consultation with the Judicial Committee of the Privy Council (Nigeria) and regional authorities. While this change localized judicial control, critics later argued that it reduced institutional independence by allowing greater executive influence in judicial appointments.
Federal-Regional Relations and Territorial Structure
Nigeria remained a federation, with powers distributed between the federal and regional governments under exclusive, concurrent, and residual lists. The 1963 Constitution affirmed regional autonomy but also outlined procedures for creating new regions or altering boundaries, ensuring flexibility within the federation.
The Mid-Western Region’s creation was constitutionally recognized, giving Nigeria four regions, Northern, Western, Eastern, and Mid-Western. Although the federal government retained reserve powers to declare a state of emergency (under Section 65), regional governments still exercised significant control over local administration, education, and economic planning. In principle, it was a federation of equals; in practice, demographic and political dominance by the North shaped the federal balance.
Fundamental Rights, Citizenship, and the Legislature
The 1963 Constitution retained and expanded the fundamental rights provisions introduced in 1960. Citizenship by birth, descent, or registration was more clearly defined to accommodate the country’s diverse populations. The National Assembly remained bicameral, comprising a Senate and a House of Representatives, and bills required the President’s assent to become law. The structure was designed to preserve representational balance and legislative accountability.

Political Dynamics and Challenges (1963–1966)
Regional Party Politics and Federal Leadership
Under the new constitutional order, Dr. Nnamdi Azikiwe became Nigeria’s first President, while Sir Abubakar Tafawa Balewa continued as Prime Minister, leading a coalition dominated by the Northern People’s Congress (NPC) and the National Council of Nigerian Citizens (NCNC).
Party politics, however, remained deeply regionalized: the NPC held power in the North, the NCNC in the East, and the Action Group (AG) in the West, which by 1963 had been weakened by internal divisions and the imprisonment of its leader, Chief Obafemi Awolowo, on charges of treasonable felony.
Electoral Disputes and Regional Crises
The 1964 federal elections were marked by boycotts, intimidation, and irregularities, especially in parts of the South. The crisis deepened in the Western Region, where the 1965 regional elections triggered widespread violence after disputed results between factions loyal to Chief Samuel Ladoke Akintola and Awolowo’s supporters. The unrest, popularly known as “Operation Wetie,” escalated from political protests into open chaos.
Constitutional mechanisms, courts, parliamentary oversight, and federal mediation, failed to contain the violence. Public confidence in the parliamentary system eroded, while the military increasingly viewed itself as the only institution capable of restoring order.
Collapse of the First Republic
On 15 January 1966, a group of young army officers staged Nigeria’s first military coup, overthrowing the civilian government and suspending the 1963 Constitution. Major General Johnson Aguiyi-Ironsi assumed power, establishing military rule under a Supreme Military Council.
The coup reflected the breakdown of regional trust, the politicisation of the military, and the inability of constitutional safeguards to manage Nigeria’s profound social and political divisions.
Strengths, Weaknesses, and Legacy
Achievements
The 1963 Republican Constitution achieved several enduring milestones:
- It affirmed Nigeria’s full republican sovereignty, ending all constitutional ties to the British Crown.
- It localized judicial authority, establishing the Supreme Court as the nation’s apex legal institution.
- It preserved federalism, while providing mechanisms for creating new regions and adjusting internal boundaries.
- It codified fundamental rightsand defined citizenship more precisely within a Nigerian context.
Structural Weaknesses
However, key weaknesses limited its success:
- The ceremonial presidencyoffered limited checks on the executive.
- The parliamentary systemstruggled within a society where ethnic and regional loyalties outweighed national party cohesion.
- The judicial appointment process, now more centralized, blurred the separation between law and politics.
- Electoral institutionslacked independence and credibility, undermining democratic legitimacy.
- Federal emergency powers, though rarely invoked formally, fostered perceptions of central dominance.
Together, these flaws eroded confidence in civilian governance and set the stage for military intervention.
Long-Term Impact
The 1963 Constitution remains a defining episode in Nigeria’s constitutional history. It embodied the aspiration for a sovereign, democratic federation but faltered under the strain of regional rivalry and weak political institutions.
Its collapse deeply influenced later constitutional choices. The 1979 and 1999 Constitutions replaced the Westminster model with a presidential system, designed to strengthen executive stability and enforce clearer separation of powers. Yet, many of the core questions first confronted in 1963, federal balance, state creation, and resource control, continue to shape Nigeria’s constitutional debates today.
Author’s Note
The Republican Constitution was a landmark in Nigeria’s assertion of sovereignty. It localized authority and symbolized national maturity but could not overcome the deeper structural and political tensions that ultimately broke the First Republic.
