Nigeria

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 Nigeria’s 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 southeast’s 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.

Armed Forces of Nigeria (AFN): Nigerian Army, Nigerian Navy (includes Coast Guard), Nigerian Air Force
Ministry of Interior: Nigeria Security and Civil Defense Corps (NSCDC); Ministry of Police Affairs: Nigeria Police Force (NPF) (2025)
note: 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: some states have created local security forces in response to increased violence, insecurity, and criminality that have exceeded the response capacity of federal government security forces, but official security forces remained the constitutional prerogative of the federal government; in 2023, the federal government began deploying thousands of "agro rangers" across 19 states and the Federal Capital Territory to help safeguard farmland and mediate conflicts, especially in areas hit by farmer-herder clashes

the military's inventory consists of a wide variety of imported weapons systems of Chinese, European, Middle Eastern, Russian (including Soviet-era), and US origin; the military is undergoing a modernization program, and in recent years has received equipment from a range of suppliers, including Brazil, China, France, Italy, Russia, South Korea, Turkey, and the US; Nigeria is also developing a defense-industry capacity, including small arms, armored personnel vehicles, and small-scale naval production (2025)

note: note: Nigeria has committed an Army combat brigade (approximately 3,000 troops) to the Multinational Joint Task Force (MNJTF), a regional counter-terrorism force comprised of troops from Benin, Cameroon, Chad, and Niger; MNJTF conducts operations against Boko Haram and other terrorist groups operating in the general area of the Lake Chad Basin and along Nigeria's northeast border; national MNJTF troop contingents are deployed within their own country territories, although cross‐border operations are conducted periodically

the Nigerian military is responsible for defending against external aggression, maintaining the country's territorial integrity, securing national borders, participating in international peacekeeping and other security missions, suppressing insurrection, and aiding civil authorities in restoring order, as well as other duties such as providing humanitarian assistance; its primary concerns are internal and maritime security; in the northeast part of the country, the military is conducting 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 terrorist-related violence has killed an estimated 35-40,000 people, mostly civilians, since 2009; in the northwest, the military faces 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; the military also continues to protect the oil industry in the Niger Delta region against militants and criminal activity and since 2021, has deployed troops alongside other security forces to quell renewed agitation in the state of Biafra; maritime security concerns include piracy and the protection of natural resources in the Gulf of Guinea 
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 Great Britain's West African colonies; the WAFF (the honorary title "Royal" was added later) served in both World Wars; in 1956, the Nigeria Regiment of the Royal WAFF 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 (2025)
