Nigeria’s Political System

Nigeria operates as a federal republic with a presidential system, with its political structure guided by the principle of separation of powers among three branches of government. The transition to civilian rule began with the general elections in February 1999, which marked the end of 15 years of military rule and established a multiparty democracy.

Nigeria’s Constitution

The current Nigerian Constitution, which is the fourth since the country gained independence, came into effect on May 29, 1999. It is modeled after the U.S. Constitution, establishing a strong executive branch, an elected legislature, and an independent judiciary. While the constitution emphasizes personal freedom and a secular state, it also allows Muslims in certain regions to follow sharia, or Islamic law. Critics argue that the constitution centralizes too much power within the federal government, often at the expense of state autonomy.

Branches of Government

The executive power in Nigeria is vested in the President, who serves as both the chief of state and head of government. The President is elected for a four-year term and may serve a maximum of two terms. The Federal Executive Council, or cabinet, includes representatives from all 36 states.

The legislative branch, known as the National Assembly, consists of a 109-member Senate and a 360-member House of Representatives. Senators represent Nigeria’s 36 states, with three senators per state, plus one for the capital city of Abuja. The House of Representatives’ seats are allocated based on population. Members of the National Assembly are also elected for four-year terms, with a two-term limit.

The judiciary is made up of the Supreme Court, the Court of Appeal, the Federal High Court, and various state-level courts, including high courts, sharia courts, and customary courts. The President appoints Supreme Court justices, subject to Senate confirmation.

Administrative Divisions

Nigeria is administratively divided into the Federal Capital Territory (Abuja) and 36 states, which are organized into six geopolitical zones: South-West, South-South, South-East, North-West, North-Central, and North-East. These divisions are designed to reflect the country’s diverse ethnic and cultural landscape.

Provincial and Local Government

Each of Nigeria’s 36 states has an elected governor and a House of Assembly. The governor, like the President, serves a maximum of two four-year terms. The number of delegates to each state’s House of Assembly is based on population, with the number varying between 24 and 40 delegates. States are further subdivided into 774 local government areas, each governed by a council responsible for basic services. Critics argue that the large number of local districts is a remnant of military rule, leading to inefficiency and waste.

 Judicial and Legal System

Nigeria’s legal system is a complex mix of statutory law, English common law, customary law, and Islamic law in the northern regions. Federal and state courts apply statutory and English common law, while local courts recognize the legitimacy of customary and Islamic law. The adoption of Islamic law in 12 northern states has sparked controversy, particularly due to its harsh penalties, although no death penalties have been carried out under Sharia law to date.


Electoral System

The President and members of the National Assembly are elected through a system of universal suffrage, with voters casting their ballots for candidates in distinct geographic constituencies. Elections follow the British first-past-the-post system, where the candidate with the most votes wins. Nigeria’s Independent National Electoral Commission (INEC) oversees the electoral process, although it has faced criticism for lack of transparency and alleged procedural improprieties in past elections.

Mass Media

Nigeria’s broadcast media is heavily regulated by the government through the National Broadcasting Commission. Radio is the most widespread medium, with stations owned by the federal government, individual states, and private operators. Television follows a similar structure. The print media, in contrast, is largely privately owned and is more critical of the government. Nigeria also has a diverse range of newspapers, newsweeklies, and tabloids, with relatively free access to the internet, which is becoming more common in workplaces and homes.


Foreign Relations

Nigeria’s foreign policy is largely focused on African affairs, emphasizing political and economic cooperation, peaceful dispute resolution, and nonalignment in global politics. Nigeria plays a leading role in the Economic Community of West African States (ECOWAS) and is actively involved in the New Partnership for Africa’s Development (NEPAD). The country has maintained good relations with its neighbors and has complied with international rulings, such as the 2002 decision by the International Court of Justice regarding the Bakassi Peninsula. Nigeria’s relations with the United States have improved significantly since the return to civilian rule in 1999, and the country has supported global initiatives like the war on terrorism.

Membership in International Organizations

Nigeria is a member of numerous international organizations, including the African Union, Commonwealth, ECOWAS, United Nations, World Trade Organization, and the International Monetary Fund, among others. The country is also a party to various international treaties on nonproliferation, environmental protection, and counter-terrorism.

Major International Treaties

Nigeria has committed to several major international treaties, including the Biological Weapons Convention, Chemical Weapons Convention, Nuclear Non-Proliferation Treaty, and the Kyoto Protocol on climate change. The country has also ratified a Mutual Legal Assistance Treaty with the United States, which facilitates cooperation on crime, drug trafficking, and counter-terrorism.
