The offices, powers, and titles of the head of state and the head of government were officially merged into the office of the presidency under the 1979 Constitution of Nigeria.
Executive power is vested in the president. The power includes the execution and enforcement of federal law and the responsibility to appoint federal executive, diplomatic, regulatory, and judicial officers. Based on constitutional provisions empowering the president to appoint and receive ambassadors and conclude treaties with foreign powers, and on subsequent laws enacted by the House, the presidency has primary responsibility for conducting foreign policy.
The president also plays a leading role in federal legislation and domestic policymaking. As part of the system of separation of powers, the Constitution gives the president the power to sign or veto federal legislation. Presidents are typically viewed as leaders of their political parties, major policymaking is significantly shaped by the outcome of presidential elections.
Ceremonial presidency and the First Republic (1963–1966)
On 1 October 1960, Nigeria gained independence from Britain. An all-Nigerian Executive Council was headed by a Prime minister, Alhaji Sir Abubakar Tafawa Balewa. On 16 November 1960, Nnamdi Azikiwe became the first governor-general of a federation of three regions of the north, east and west, with Lagos as the Federal Capital. Each of the regions was headed by a premier with a governor as ceremonial head. The governors and governor-general represented the Queen of Nigeria, Elizabeth II. On 1 October 1963, Nigeria became a Federal republic thereby abolishing its monarchy, but remained a member of the Commonwealth of Nations. An amendment to the 1960 Independence Constitution replaced the office of the governor-general with that of the president. Nnamdi Azikwe was sworn into that office on 1 October 1963.[4] The office at that time was primarily ceremonial, and the main duties of the president were on such things as receiving foreign dignitaries and opening Parliament.
Military rule (1966–1979)
In a January 1966 failed coup d'état, a group of army officers, led by Major Chukwuma Nzeogwu, overthrew the federal and regional governments, killed the prime minister Abubakar Tafawa Balewa, and tried to take control of the government. Nzeogwu was countered, captured, and imprisoned by the Army general officer commanding Major General Johnson Aguiyi-Ironsi. Aguiyi-Ironsi was named Military Head of State.[5]
In July 1966, a group of northern army officers revolted against the government, killed General Johnson Aguiyi-Ironsi, and appointed the army chief of staff, Lieutenant Colonel Yakubu Gowon as the head of the new military government.[6]
In 1975, General Yakubu Gowon was deposed and Brigadier Murtala Mohammed was made head of the Federal Military Government of Nigeria until his assassination in 1976.[7] Upon his death, the chief-of-staff, Supreme Headquarters (equivalent to a vice president) General Olusegun Obasanjo assumed office as head of state in a meeting of the Supreme Military Council, keeping the chain of command established by General Murtala Muhammed in place. General Obasanjo was responsible for completing the democratic transition begun by his predecessor, which culminated in an election in August 1979.[8]
On 1 October 1979, after more than 13 years of military rule, Nigeria returned to democratic rule. The National Party of Nigeria emerged victorious in the presidential election and Shehu Shagari became the first democratically elected president.[9]
In August 1985, General Buhari's government was peacefully overthrown by the Army chief of staff, Major General Ibrahim Babangida. Babangida became the president and chairman of the Armed Forces Ruling Council.
On 26 August 1993, General Babangida stepped down and chose an interim government to replace him. Ernest Shonekan was named as interim head of state.[11] General Sani Abacha seized power from Shonekan on 17 November 1993, and became head of state and chairman of the Provisional Ruling Council.[12]
On 29 May 1999, General Abdulsalami Abubakar stepped down,[22] and handed over power to a former military head of state, Olusegun Obasanjo, after being elected some months prior. Obasanjo served two terms in office.
On 29 May 2007, Umaru Musa Yar'Adua was sworn in as president of the Federal Republic of Nigeria and the 13th head of state completing the first successful transition of power, from one democratically elected president to another in Nigeria.[23][24][25] Yar'Adua died on 5 May 2010 at the presidential villa, in Abuja, Nigeria, becoming the second head of state to die there after General Sani Abacha.[26][27][28][29][30][31][32]
On 29 May 2015, Muhammadu Buhari, a former military head of state was sworn in as president of the Federal Republic of Nigeria and the 15th head of state after winning the general election.[39][40][41][42][43][44] He also served two terms in office.
The president of Nigeria is elected using a modified two-round system with up to three rounds. To be elected in the first round, a candidate must receive a plurality of the votes, as well as over 25% of the vote in at least 24 of the 36 states and the Federal Capital Territory. If no candidate passes this threshold, a second round will be held between the top candidate and the next candidate to have received a majority of votes in the highest number of states. In the second round, a candidate still must receive the most votes, as well as over 25% of the vote in at least 24 of the 36 states and the Federal Capital Territory in order to be elected. If neither candidate passes this threshold, a third round will be held, where a simple majority of the votes is required to be elected.[46]
Presidential candidates run for office with a running mate, their party's candidate for vice president.
