The Federal Government of Nigeria is composed of three distinct branches: legislative, executive, and judicial, whose powers are vested by the Constitution of Nigeria in the National Assembly, the President, and the federal courts, including the Supreme Court, respectively. The Constitution provides a separation and balance of powers among the three branches and aims to prevent the repetition of past mistakes made by the government.
In 1973, Ostheimer M. John talked about the Nigerian Politics in relation to the First Republican Crisis and Collapse as an historical background, described by Polyethnics.
Nigeria is a federal republic, with executive power exercised by the president. The president is the head of state, the head of government, and the head of a multi-party system. Nigerian politics takes place within a framework of a federal, presidential, representative democratic republic, in which executive power is exercised by the government. Legislative power is held by the federal government and the two chambers of the legislature: the House of Representatives and the Senate. Together, the two chambers make up the law-making body in Nigeria, called the National Assembly, which serves as a check on the executive arm of government. The Economist Intelligence Unit rated Nigeria a "hybrid regime" in 2019. The federal government, state, and local governments of Nigeria aim to work cooperatively to govern the nation and its people. Nigeria became a member of the British Commonwealth upon its independence from British colonial rule on October 1, 1960. Both men and women participate in government in Nigeria.
