In ancient and pre-colonial times, the area of present-day Nigeria was occupied by a great diversity 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 in 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 general 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.
Nigeria is a major hub for transnational drug trafficking networks entrenched throughout the world and supplying cocaine to Asia and Europe, heroin to Europe and North America, and methamphetamine to South Africa, Southeast Asia, Australia, and New Zealand; also exporting massive quantities of opioids such as tramadol and captagon along with crack cocaine; a major source of precursor or essential chemicals used in the production of illicit narcotics
Nigeria’s population is projected to grow from more than 186 million people in 2016 to 392 million in 2050, becoming the world’s fourth most populous country. Nigeria’s 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.

Nigeria-Cameroon: Joint Border Commission with Cameroon reviewed 2002 ICJ ruling on the entire boundary and bilaterally resolved differences, including June 2006 Greentree Agreement that immediately ceded sovereignty of the Bakassi Peninsula to Cameroon with a phaseout of Nigerian control within two years while resolving patriation issues; demarcation of the Bakassi Peninsula and adjoining border areas should be finalized in 2022; as Lake Chad’s evaporation exposed dry land, only Nigeria and Cameroon have heeded the Lake Chad Commission's admonition to ratify the delimitation treaty which also includes the Chad-Niger and Niger-Nigeria boundaries
Nigeria-Cameroon-Equatorial Guinea: the ICJ ruled on an equidistance settlement of Cameroon-Equatorial Guinea-Nigeria maritime boundary in the Gulf of Guinea, but imprecisely defined coordinates in the ICJ decision and a sovereignty dispute between Equatorial Guinea and Cameroon over an island at the mouth of the Ntem River all contribute to the delay in implementation
