The First Republic (1963 – 1966)

Although Nigeria became independent on October 1, 1960, it remained a British Dominion under Queen Elizabeth II as Head of State, represented by a Governor-General. Exactly three years later, on October 1, 1963, Nigeria adopted the 1963 Republican Constitution, severing remaining colonial ties with the British Crown and becoming the Federal Republic of Nigeria.

Structure of the First Republic

• Parliamentary System: Modeled after the British Westminster system.
• President (Head of State): Dr. Nnamdi Azikiwe became Nigeria's first President (a ceremonial role).
• Prime Minister (Head of Government): Sir Abubakar Tafawa Balewa exercised executive authority.
• Creation of Mid-Western Region (1963): In August 1963, the Mid-Western Region was carved out of the Western Region following a plebiscite, with Benin City as its capital, creating a 4-region federation (North, West, East, Mid-West).

1. The First Military Coup (January 15, 1966)

• Spearheaded by young army majors led by Major Chukwuma Kaduna Nzeogwu and Major Emmanuel Ifeajuna.
• Prominent political leaders were assassinated, including Prime Minister Abubakar Tafawa Balewa, Northern Premier Ahmadu Bello, Western Premier Ladoke Akintola, and Federal Finance Minister Festus Okotie-Eboh.
• Major General Johnson Aguiyi-Ironsi (General Officer Commanding the Nigerian Army) assumed power as Head of State.
• Ironsi suspended the 1963 Constitution and promulgated Unification Decree No. 34 of 1966, abolishing federalism in favor of a unitary system. This sparked severe political unrest in Northern Nigeria.

2. The Counter-Coup (July 29, 1966)

• Northern military officers launched a counter-coup, resulting in the assassination of Gen. Aguiyi-Ironsi and the Military Governor of the Western Region, Lt. Col. Adekunle Fajuyi, in Ibadan.
• Lt. Col. (later General) Yakubu Gowon (aged 31) became Head of State.
• On May 27, 1967, Gowon issued a decree abolishing the four regional divisions and creating 12 States to weaken regional secessionist leverage and decentralize administrative authority.

3. The Nigerian Civil War / Biafran War (1967 – 1970)

• On May 30, 1967, the Military Governor of the Eastern Region, Lt. Col. Chukwuemeka Odumegwu Ojukwu, declared the secession of the Eastern Region as the sovereign Republic of Biafra.
• Armed conflict commenced on July 6, 1967, when federal forces fired the first shots at Gakem in present-day Cross River State. The war lasted 30 months, resulting in an estimated 1 to 3 million casualties, largely due to starvation and malnutrition.
• On January 15, 1970, Biafran forces officially surrendered at Dodan Barracks in Lagos, signed by Major General Philip Effiong (Ojukwu having fled into exile in Côte d'Ivoire).
• General Gowon declared the historic policy of "No Victor, No Vanquished" and instituted the 3Rs Program: Reconstruction, Rehabilitation, and Reintegration.
• To foster national integration among Nigerian youth, Gowon established the National Youth Service Corps (NYSC) via Decree No. 24 on May 22, 1973.

The June 12, 1993 Election Milestone

On June 12, 1993, Nigeria conducted a presidential election between Chief M.K.O. Abiola of the Social Democratic Party (SDP) and Alhaji Bashir Tofa of the National Republican Convention (NRC). Using Option A4 voting system, the election was declared by national and international observers as the freest, fairest, and most peaceful election in Nigerian history.

However, Gen. Ibrahim Babangida annulled the election results before official completion of announcement by the National Electoral Commission (NEC led by Prof. Humphrey Nwosu). This triggered widespread civil disobedience and pro-democracy agitation led by NADECO (National Democratic Coalition). In June 2018, President Muhammadu Buhari officially declared June 12 as Nigeria's Democracy Day and conferred the posthumous highest national honor (GCFR) on Chief M.K.O. Abiola.
