Background

In ancient and pre-colonial times, the area of present-day Nigeria was occupied by a variety of ethnic groups with different languages and traditions. These included large Islamic kingdoms such as Borno, Kano, and the Sokoto Caliphate dominating the north, the Benin and Oyo Empires that controlled much of modern western Nigeria, and more decentralized political entities and city states in the south and southeast. In 1914, the British amalgamated their separately administered northern and southern territories into a Colony and Protectorate of Nigeria.

Nigeria achieved independence from Britain in 1960 and transitioned to a federal republic with three constituent states in 1963 under President Nnamdi AZIKIWE. This structure served to enflame regional and ethnic tension, contributing to a bloody coup led by predominately southeastern military officers in 1966 and a countercoup later that year masterminded by northern officers. In the aftermath of this tension, the governor of Nigeriaâs Eastern Region, centered on the southeast, declared the region independent as the Republic of Biafra. The ensuring civil war (1967-1970), resulted in more than a million deaths, many from starvation. While the war forged a stronger Nigerian state and national identity, it contributed to long-lasting mistrust of the southeastâs predominantly Igbo population. Wartime military leader Yakubu GOWON ruled until a bloodless coup by frustrated junior officers in 1975. This generation of officers, including Olusegun OBASANJO, Ibrahim BABANGIDA, and Muhammadu BUHARI, who would all later serve as president, continue to exert significant influence in Nigeria to the present day.

Military rule predominated until the first durable transition to civilian government and adoption of a new constitution in 1999. The elections of 2007 marked the first civilian-to-civilian transfer of power in the country's history. National and state elections in 2011 and 2015 were generally regarded as credible. The 2015 election was also heralded for the fact that the then-umbrella opposition party, the All Progressives Congress, defeated the long-ruling (since 1999) People's Democratic Party and assumed the presidency, marking the first peaceful transfer of power from one party to another. Presidential and legislative elections in 2019 and 2023 were deemed broadly free and fair despite voting irregularities, intimidation, and violence. The government of Africa's most populous nation continues to face the daunting task of institutionalizing democracy and reforming a petroleum-based economy whose revenues have been squandered through decades of corruption and mismanagement. In addition, Nigeria faces increasing violence from Islamic terrorism, largely in the northeast, large scale criminal banditry, secessionist violence in the southeast, and competition over land and resources nationwide.

Demographic profile

Nigeriaâs population is projected to grow from more than 186 million people in 2016 to 392 million in 2050, becoming the worldâs fourth most populous country. Nigeriaâs sustained high population growth rate will continue for the foreseeable future because of population momentum and its high birth rate. Abuja has not successfully implemented family planning programs to reduce and space births because of a lack of political will, government financing, and the availability and affordability of services and products, as well as a cultural preference for large families. Increased educational attainment, especially among women, and improvements in health care are needed to encourage and to better enable parents to opt for smaller families.

Nigeria needs to harness the potential of its burgeoning youth population in order to boost economic development, reduce widespread poverty, and channel large numbers of unemployed youth into productive activities and away from ongoing religious and ethnic violence. While most movement of Nigerians is internal, significant emigration regionally and to the West provides an outlet for Nigerians looking for economic opportunities, seeking asylum, and increasingly pursuing higher education. Immigration largely of West Africans continues to be insufficient to offset emigration and the loss of highly skilled workers. Nigeria also is a major source, transit, and destination country for forced labor and sex trafficking.

note 1: on 4 May 2022, the Centers for Disease Control and Prevention issued a Travel Health Notice for a Yellow Fever outbreak in Nigeria; a large, ongoing outbreak of yellow fever in Nigeria began in September 2017; the outbreak is now spread throughout the country with the Nigerian Ministry of Health reporting cases of the disease in multiple states (Bauchi, Benue, Delta, Ebonyi, and Enugu); the CDC recommends travelers going to Nigeria should receive vaccination against yellow fever at least 10 days before travel and should take steps to prevent mosquito bites while there; those never vaccinated against yellow fever should avoid travel to Nigeria during the outbreak (see attached map)

note 2: on 31 August 2023, the US Centers for Disease Control and Prevention (CDC) issued a Travel Alert for polio in Africa; Nigeria is currently considered a high risk to travelers for circulating vaccine-derived polioviruses (cVDPV); vaccine-derived poliovirus (VDPV) is a strain of the weakened poliovirus that was initially included in oral polio vaccine (OPV) and that has changed over time and behaves more like the wild or naturally occurring virus; this means it can be spread more easily to people who are unvaccinated against polio and who come in contact with the stool or respiratory secretions, such as from a sneeze, of an âinfectedâ person who received oral polio vaccine; the CDC recommends that before any international travel, anyone unvaccinated, incompletely vaccinated, or with an unknown polio vaccination status should complete the routine polio vaccine series; before travel to any high-risk destination, the CDC recommends that adults who previously completed the full, routine polio vaccine series receive a single, lifetime booster dose of polio vaccine

note 3: on 20 September 2023, the Centers for Disease Control and Prevention updated a Travel Health Alert for a diphtheria outbreak in several states in Nigeria; vaccination against diphtheria is essential to protect against disease; if you are traveling to an affected area, you should be up to date with your diphtheria vaccines; before travel, discuss the need for a booster dose with your healthcare professional; diphtheria is a serious infection caused by strains of Corynebacterium diphtheriae bacteria that make a toxin from which people get very sick; diphtheria bacteria spread from person to person through respiratory droplets like from coughing or sneezing; people can also get sick from touching open sores or ulcers of people sick with diphtheria (see attached map)

note 1: The Nigeria Centre for Disease Control (NCDC) is reporting yellow fever outbreaks in multiple states (Bauchi, Benue, Delta, Ebonyi, and Enugu). Unless vaccinated, travelers should not visit these areas. Yellow fever is caused by a virus transmitted through bites of infected mosquitoes. Travelers to Nigeria should take steps to prevent yellow fever by getting vaccinated at least 10 days before travel and taking steps to prevent mosquito bites. Map courtesy of CDC. :

Food insecurity

widespread lack of access: due to persistent civil conflict in the northern areas,Â floods, high food prices, and an economic slowdown - about 25.3 million people are projected to face acute food insecurity during the June to August 2023 lean season; this would be a significant deterioration compared to last year, when 19.45 million people were estimated to be acutely food insecure; acute food insecurity is mostly driven by the deterioration of security conditions and conflicts in northern states, which have led to the displacement of about 3.17 million people as of March 2022 (the latest data available) and are constraining farmersâ access to their lands; widespread flooding in 2022, affecting about 4.5 million people across the country, has further compounded conditions, particularly in areas already facing high levels of insecurity; high food prices and the expected slowdown in economic growth in 2023 are additional drivers of acute food insecurity (2023)

Constitution

history: several previous; latest adopted 5 May 1999, effective 29 May 1999

amendments: proposed by the National Assembly; passage requires at least two-thirds majority vote of both houses and approval by the Houses of Assembly of at least two thirds of the states; amendments to constitutional articles on the creation of a new state, fundamental constitutional rights, or constitution-amending procedures requires at least four-fifths majority vote by both houses of the National Assembly and approval by the Houses of Assembly in at least two thirds of the states; passage of amendments limited to the creation of a new state require at least two-thirds majority vote by the proposing National Assembly house and approval by the Houses of Assembly in two thirds of the states; amended several times, last in 2018

Executive branch

chief of state: President Bola Ahmed Adekunle TINUBU (since 29 May 2023)

head of government: President Bola Ahmed Adekunle TINUBU (since 29 May 2023)

cabinet: Federal Executive Council appointed by the president but constrained constitutionally to include at least one member from each of the 36 states

elections/appointments: president directly elected by qualified majority popular vote and at least 25% of the votes cast in 24 of Nigeria's 36 states; president elected for a 4-year term (eligible for a second term); election last held on 25 February 2023 (next to be held on 27 February 2027) note - the president is chief of state, head of government, and commander-in-chief of the armed forces

Telecommunication systems

general assessment: one of the larger telecom markets in Africa subject to sporadic access to electricity and vandalism of infrastructure; most Internet connections are via mobile networks; market competition with affordable access; LTE technologies available but GSM is dominant; mobile penetration high due to use of multiple SIM cards and phones; government committed to expanding broadband penetration; operators to deploy fiber optic cable in six geopolitical zones and Lagos; operators invested in base stations to deplete network congestion; submarine cable break in 2020 slowed speeds and interrupted connectivity; Nigeria concluded its first 5G spectrum auction in 2021 and granted licenses to two firms; construction of 5G infrastructure has not yet been completed (2022)

domestic: fixed-line subscribership remains less than 1 per 100 persons; mobile-cellular subscribership is 91 per 100 persons (2021)

international: country code - 234; landing point for the SAT-3/WASC, NCSCS,Â MainOne, Glo-1 & 2, ACE, and EquianoÂ fiber-optic submarine cable that provides connectivity to Europe and South and West Africa; satellite earth stations - 3 Intelsat (2 Atlantic Ocean and 1 Indian Ocean) (2019)

Military and security forces

Armed Forces of Nigeria (AFN): Army, Navy (includes Coast Guard), Air Force

Ministry of Interior: Nigeria Security and Civil Defense Corps (NSCDC); Ministry of Police Affairs: Nigeria Police Force (NPF) (2024)

note 1: the NSCDC is a paramilitary agency commissioned to assist the military in the management of threats to internal security, including attacks and natural disasters

note 2: the Office of the National Security Advisor is responsible for coordinating all security and enforcement agencies, including the Department of State Security (DSS), the NSCDC, the Ministry of Justice, and the NPF; border security responsibilities are shared among the NPF, the DSS, the NSCDC, Nigeria Customs Service, Immigration Service, and the AFN

note 3: some states have created local security forces akin to neighborhood watches in response to increased violence, insecurity, and criminality that have exceeded the response capacity of federal government security forces but as of January 2024, official security forces remained the constitutional perogative of the federal government

Military - note

the Nigerian military is sub-Saharan Africaâs largest and regarded as one of its most capable forces; the military's primary concerns are internal and maritime security, and it faces a number of challenges; the Army is deployed in all 36 of the country's states; in the northeast, it is conducting counterinsurgency/counterterrorist operations against the Boko Haram (BH) and Islamic State of Iraq and ash-Sham in West Africa (ISIS-WA) terrorist groups, where it has deployed as many as 70,000 troops at times and jihadist-related violence has killed an estimated 35-40,000 people, mostly civilians, since 2009; in the northwest, it faces growing threats from criminal gangs--locally referred to as bandits--and violence associated with long-standing farmer-herder conflicts, as well as BH and ISIS-WA terrorists; bandits in the northwestern Nigeria are estimated to number in the low 10,000s and violence there has killed more than 10,000 people since the mid-2010s; the military also continues to protect the oil industry in the Niger Delta region against militants and criminal activity; since 2021, additional troops and security forces have been deployed to eastern Nigeria to quell renewed agitation for a state of Biafra (Biafra seceded from Nigeria in the late 1960s, sparking a civil war that caused more than 1 million deaths)

the Navy is focused on maritime security in the Gulf of Guinea; since 2016, it has developed a maritime strategy, boosted naval training and its naval presence in the Gulf, increased participation in regional maritime security efforts, and acquired a number of new naval platforms, including offshore and coastal patrol craft, fast attack boats, and air assets

the Nigerian military traces its origins to the Nigeria Regiment of the West African Frontier Force (WAFF), a multi-regiment force formed by the British colonial office in 1900 to garrison the West African colonies of Nigeria (Lagos and the protectorates of Northern and Southern Nigeria), Gold Coast, Sierra Leone, and Gambia; the WAFF served with distinction in both East and West Africa during World War I; in 1928, it received royal recognition and was re-named the Royal West African Frontier Force (RWAFF); the RWAFF went on to serve in World War II as part of the British 81st and 82nd (West African) divisions in the East Africa and Burma campaigns; in 1956, the Nigeria Regiment of the RWAFF was renamed the Nigerian Military Forces (NMF) and in 1958, the colonial government of Nigeria took over control of the NMF from the British War Office; the Nigerian Armed Forces were established following independence in 1960 (2023)
