Nigeria, officially the Federal Republic of Nigeria, is a country in West Africa. It is situated between the Sahel to the north and the Gulf of Guinea in the Atlantic Ocean to the south. It covers an area of 923,769 square kilometres (356,669 sq mi). With a population of more than 230 million, it is the most populous country in Africa, and the world's sixth-most populous country. Nigeria borders Niger in the north, Chad in the northeast, Cameroon in the east, and Benin in the west. Nigeria is a federal republic comprising 36 states and the Federal Capital Territory, where its capital, Abuja, is located. The largest city in Nigeria is Lagos, one of the largest metropolitan areas in the world and the largest in Africa.
The history of Nigeria can be traced to the earliest inhabitants whose date remains at least 13,000 BC through the early civilizations such as the Nok culture which began around 1500 BC. Numerous ancient African civilizations settled in the region that is known today as Nigeria, such as the Kingdom of Nri, the Benin Kingdom, and the Oyo Empire. Islam reached Nigeria through the Bornu Empire between and Hausa Kingdom during the 11th century, while Christianity came to Nigeria in the 15th century through Augustinian and Capuchin monks from Portugal to the Kingdom of Warri. The Songhai Empire also occupied part of the region. Through contact with Europeans, early harbour towns such as Calabar, Badagry and Bonny emerged along the coast after 1480, which did business in the transatlantic slave trade, among other things. Conflicts in the hinterland, such as the civil war in the Oyo Empire, meant that new enslaved people were constantly being "supplied".
Nigeria is the most populous country in Africa and the sixth most populous in the world. It is also one of the most densely populated countries in Africa, with approximately 218.5 million people in an area of 923,768 km2 (356,669 sq mi).
The federal government of Nigeria is composed of three distinct branches: the executive, the legislative, and the judicial, whose powers are vested and bestowed upon by the Constitution of the Federal Republic of Nigeria. One of the primary functions of the constitution is that it provides for separation and balance of powers among the three branches and aims to prevent the repetition of past mistakes made by the government. Other functions of the constitution include a division of power between the federal government and the states, and protection of various individual liberties of the nation's citizens.
Since independence, with Jaja Wachuku as the first Minister for Foreign Affairs and Commonwealth Relations, later called External Affairs, Nigerian foreign policy has been characterised by a focus on Africa as a regional power and by attachment to several fundamental principles: African unity and independence; capability to exercise hegemonic influence in the region: peaceful settlement of disputes; non-alignment and non-intentional interference in the internal affairs of other nations; and regional economic cooperation and development. In carrying out these principles, Nigeria participates in the African Union, the Economic Community of West African States (ECOWAS), the Non-Aligned Movement, the Commonwealth of Nations, and the United Nations.
Biafra, officially the Republic of Biafra, was a partially recognised state in West Africa that declared independence from Nigeria and existed from 1967 until 1970. Its territory consisted of the former Eastern Region of Nigeria, predominantly inhabited by the Igbo ethnic group. Biafra was established on 30 May 1967 by Igbo military officer and Eastern Region governor Chukwuemeka Odumegwu Ojukwu under his presidency, following a series of ethnic tensions and military coups after Nigerian independence in 1960 that culminated in the 1966 anti-Igbo pogrom.
Abuja is the capital city of the Federal Republic of Nigeria, strategically situated at the geographic midpoint of the country within the Federal Capital Territory (FCT). As the seat of the Federal Government of Nigeria, it hosts key national institutions, landmarks, and buildings spread across its over 50 districts. It replaced Lagos, as the capital on 12 December 1991.
Lagos, or Lagos City, is a large metropolitan city in southwest Nigeria. With an upper population estimated above 21 million dwellers, it is the largest city in Nigeria, and the most populous urban area on the African continent. Lagos was the national capital of Nigeria until the government's December 1991 decision to move their capital to Abuja in the centre of the country. Lagos is a major African financial centre and is the economic hub of Lagos State and Nigeria at large. The city has a significant influence on commerce, entertainment, technology, education, politics, tourism, art, and fashion in Africa. Lagos is also among the top ten of the world's fastest-growing cities and urban areas. In 2024, Time Out magazine ranked Lagos as the 19th Best City to visit in the World. A megacity, it has the fourth-highest GDP in Africa, and houses one of the largest and busiest seaports on the continent. Due to the large urban population and port traffic volumes, Lagos is classified as a Medium-Port Megacity and the most fast rising city.
Nigeria is a federation of 36 states, each of which is a semi-autonomous political unit that shares power with the federal government as enumerated under the Constitution of the Federal Republic of Nigeria. In addition to the states, there is the Federal Capital Territory (FCT), in which the capital city of Abuja is located. The FCT is not a state, but a territory of the federal government, governed by an administration headed by a minister. Each state is subdivided into local government areas (LGAs). There are 774 local governments in Nigeria. Under the Nigerian Constitution, the 36 states enjoy substantial autonomy but are not sovereign entities, as ultimate authority lies with the federal government. Amendments to the constitution can be proposed by the National Assembly, but for an amendment to be valid, it must be approved by a two-third majority of the 36 state legislatures, as required under Section 9 of the 1999 Constitution of Nigeria.
The Peoples Democratic Party (PDP) is one of the two major contemporary political parties in Nigeria, along with its main rival, the All Progressives Congress (APC).
Lagos State is a state in South West, Nigeria. Of the 36 Nigerian states, Lagos is the second most populous state but the smallest in terms of land mass. Bounded to the south by the Bight of Benin and to the west by the international border with Benin for 10 km, Lagos State borders Ogun State to the north for about 283 km, making it the only Nigerian state to border only one other state. Named for the city of Lagos—the most populous city in Africa—the state was formed from the Western Region and the former Federal Capital Territory on 27 May 1967.
The Niger Delta is the delta of the Niger River sitting directly on the Gulf of Guinea on the Atlantic Ocean in Nigeria. It is located within nine coastal southern Nigerian states, which include: all six states from the South South geopolitical zone, one state (Ondo) from South West geopolitical zone and two states from South East geopolitical zone.
Kano State is one of the 36 states of Nigeria, located in the northern region of the country. According to the national census done in 2006, Kano State is the most populous state in Nigeria. The recent official estimates taken in 2016 by the National Bureau of Statistics found that Kano State was still the largest state by population in Nigeria. Created in 1967 out of the former Northern Region, Kano State borders on Katsina State to the northwest for about 210 km, Jigawa State to the northeast for 355 km, Bauchi State to the southeast for 131 km, and Kaduna State to the southwest for 255 km. The state's capital and largest city is the city of Kano, the second most populous city in Nigeria after Lagos. The incumbent governor of the state is Abba Kabir Yusuf. He was sworn in on 29 May 2023.
Borno State is a state in the North-East geopolitical zone of Nigeria. It is bordered by Yobe to the west for about 421 km, Gombe to the southwest for 93 km, and Adamawa to the south while its eastern border forms part of the national border with Cameroon for about 426 km. Its northern border forms part of the national border with Niger for about 223 km, mostly across the Komadougou-Yobe River, and its northeastern border forms all of the national border with Chad for 85 km. It is the only Nigerian state to border up to three countries. It takes its name from the historic emirate of Borno, with the emirate's old capital of Maiduguri serving as the capital city of Borno State. The state was formed in 1976 when the former North-Eastern State was broken up. It originally included the area that is now Yobe State, which became a distinct state in 1991.
Nigerian Americans are Americans who are of Nigerian ancestry. The number of Nigerian immigrants residing in the United States is rapidly growing, expanding from a small 1980 population of 25,000. The 2022 American Community Survey (ACS) estimated that 712,294 residents of the US were of Nigerian ancestry. The 2019 ACS further estimated that around 392,811 of these (85%) had been born in Nigeria. This puts the American-born Nigerian American population a little over 400,000. Similar to its status as the most populous country in Africa, Nigeria is also the African country with the most migrants to the US, as of 2013. In a study which was carried out by consumer genetics company 23andMe which involved the DNA of 50,281 people of African descent in the United States, Latin America, and Western Europe, it was revealed that Nigeria was the most common country of origin for testers from the United States, the French Caribbean, and the British Caribbean.
Nigerians or the Nigerian people are citizens of Nigeria or people with ancestry from Nigeria. The name Nigeria was derived from the Niger River running through the country. This name was allegedly coined in the late 19th century by British journalist Flora Shaw, who later married Baron Frederick Lugard, a British colonial administrator. Nigeria is composed of various ethnic groups and cultures and the term Nigerian refers to a citizenship-based civic nationality. Nigerians are derived from over 250 ethno-linguistic groups. Though there are multiple ethnic groups in Nigeria, economic factors result in significant mobility of Nigerians of multiple ethnic and religious backgrounds to reside in territories in Nigeria that are outside their ethnic or religious background, resulting in the mixing of the various ethnic and religious groups, especially in Nigeria's cities. The English language is the lingua franca of Nigerians. Nigeria is divided roughly in half between Muslims, who live mostly in the north, and Christians, who live mostly in the south; indigenous religions, such as those native to the Igbo and Yoruba ethnicities, are in the minority.
The Nigerian Army (NA) is the land force of the Nigerian Armed Forces. It is the largest component of the Nigerian Armed Forces. The President of Nigeria is the Commander-in-Chief of the Nigerian Army, and its professional head is the Chief of Army Staff, who is the highest ranking military officer of the Nigerian Army. It is governed by the Nigerian Army Council (NAC). The Nigerian Army is operationally and geographically divided into ten divisions, the basic field formation. The army has been involved in operations throughout the country, most especially during the Nigerian Civil War, and has undertaken major operations abroad. Nigerian Army officers have served as chiefs of defence in other countries, with Brigadier General Maxwell Khobe serving as Sierra Leone chief of staff in 1998–1999, and Nigerian officers acting as Command Officer-in-Charge of the Armed Forces of Liberia from at least 2007. The Nigerian Army is globally renowned for its professionalism and experience in counterterrorism and counterinsurgency; in 2022, the Nigerian Army won the award for the "Best Land Force in National Defence in Africa" in Banjul, Gambia.
Under civil law, Nigeria does not recognize polygamous unions. However, 12 out of the 36 Nigerian states recognize polygamous marriages as being equivalent to monogamous marriages. All twelve states are governed by Sharia law. The states, which are all northern, include the states of Bauchi, Borno, Gombe, Jigawa, Kaduna, Kano, Katsina, Kebbi, Niger, Sokoto, Yobe, and Zamfara which allows for a man to take more than one wife.
Boko Haram, officially known as Jamā'at Ahl as-Sunnah lid-Da'wah wa'l-Jihād, is a self-proclaimed jihadist terrorist organization based in northeastern Nigeria and also active in Chad, Niger, northern Cameroon, and Mali. In 2016, the group split, resulting in the emergence of a hostile faction known as the Islamic State's West Africa Province. Muslim scholars generally oppose both groups.
The Boko Haram insurgency began in July 2009, when the militant Islamist and jihadist rebel group Boko Haram started an armed rebellion against the government of Nigeria. The conflict is taking place within the context of long-standing issues of religious violence between Nigeria's Muslim and Christian communities, and the insurgents' ultimate aim is to establish an Islamic state in the region.
