Nigeria instance of sovereign state
First Republic, Civil War and coups (1960–1977)
Nigeria gained a degree of self-rule in 1954, and full independence from the United Kingdom on 1 October 1960, as the Federation of Nigeria with Abubakar Tafawa Balewa as its prime minister, while retaining the British monarch, Elizabeth II, as nominal head of state and Queen of Nigeria. Azikiwe replaced the colonial governor-general in November 1960. At independence, the cultural and political differences were sharp among Nigeria's dominant ethnic groups: the Hausa in the north, Igbo in the east and Yoruba in the west. The Westminster system of government was retained, and thus the President's powers were generally ceremonial. The parliamentary system of government had Abubakar Tafawa Balewa as Prime Minister and Nnamdi Azikiwe as the ceremonial president.
The founding government was a coalition of conservative parties: the Northern People's Congress led by Sir Ahmadu Bello, a party dominated by Muslim northerners, and the Igbo and Christian-dominated National Council of Nigeria and the Cameroons led by Nnamdi Azikiwe. The opposition consisted of the comparatively liberal Action Group, which was largely dominated by the Yoruba and led by Obafemi Awolowo. An imbalance was created in the polity as the result of the 1961 plebiscite. Southern Cameroons opted to join the Republic of Cameroon while Northern Cameroons chose to join Nigeria. The northern part of the country became larger than the southern part.Politics
Government
Nigeria is a federal republic modelled after the United States, with 36 states and capitol Abuja as an independent unit. The executive power is exercised by the President. The president is both head of state and head of the federal government; the president is elected by popular vote to a maximum of two four-year terms. The president's power is checked by a Senate and a House of Representatives, which are combined in a bicameral body called the National Assembly. The Senate is a 109-seat body with three members from each state and one from the capital region of Abuja; members are elected by popular vote to four-year terms. The House contains 360 seats, with the number of seats per state determined by population.The Nigerian president is elected in a modified two-round system. To be elected in the first round, a candidate must receive a relative majority of the votes and more than 25% of the votes in at least 24 of the 36 states. If no candidate reaches this hurdle, a second round of voting takes place between the leading candidate and the next candidate who received the majority of votes in the highest number of states. Presidential candidates take a "running mate" (candidate for the vice-presidency) who is both ethnically and religiously the opposite of themselves: a Christian candidate from the South will choose a Muslim running mate from the North - and vice versa. There is no law prescribing this, yet all presidential candidates since the existence of the Fourth Republic have adhered to this rule.
State governors, like the president, are elected for four years and may serve a maximum of two terms.
