Nigeria is a country on the western coast of Africa, on the Gulf of Guinea, and is Africa’s most populous nation, with an estimated 237.5 million people in 2025. It is a federal republic made up of 36 states and the Federal Capital Territory of Abuja, and it is home to more than 250 ethnic groups speaking hundreds of languages.

Where Is Nigeria Located?

Nigeria sits in West Africa on the Gulf of Guinea, part of the Atlantic Ocean. It shares land borders with Benin to the west, Niger to the north, Chad to the northeast, and Cameroon to the east, and it covers about 923,768 square kilometers (356,669 square miles), making it roughly twice the size of California (Britannica). The capital is Abuja, planned and built in the 1980s specifically to serve as a neutral seat of government at the country’s geographic center, while Lagos, on the coast, remains Nigeria’s largest city and commercial hub (Britannica).

Nigeria’s Geography

Nigeria’s terrain runs from mangrove swamps and rainforest along the southern coast to open savanna and semi-arid scrubland near the Sahel in the north. The country is drained by two major rivers, the Niger and the Benue, which meet near Lokoja before flowing south into the Niger Delta, a low-lying wetland region stretching roughly 240 kilometers north to south and spreading about 320 kilometers along the coast, covering some 36,000 square kilometers of freshwater swamp, mangrove thicket, and oxbow lakes (Britannica). Inland, the landscape rises to the Jos Plateau in the center of the country and the Mandara Mountains along the eastern border with Cameroon. Climate varies accordingly, from humid equatorial conditions in the south to arid conditions in the far north (Britannica).

A Brief History of Nigeria

Long before Nigeria existed as a single political entity, its territory held a succession of powerful states. The Kanem-Borno empire controlled trade routes around Lake Chad for centuries, the Hausa city-states developed as commercial centers across the north, the Benin Kingdom built a sophisticated court culture in the south, and Yoruba city-states such as Oyo and Ife flourished in the southwest. Between roughly 1804 and 1808, the Fulani scholar Usman dan Fodio led a jihad that founded the Sokoto Caliphate, a large Islamic state that came to dominate much of what is now northern Nigeria (Britannica).

Britain expanded its influence over the region through the 19th century, formally uniting the Northern and Southern Protectorates into a single colony in 1914. Nigeria gained independence from Britain on October 1, 1960, and became a republic in 1963 (Britannica). The young federation was tested almost immediately: a 1966 military coup and countercoup deepened regional and ethnic tensions, and in May 1967 the Eastern Region declared itself the independent Republic of Biafra. The resulting Nigerian Civil War lasted from 1967 to 1970 and ended with Biafra’s surrender and reincorporation into Nigeria; estimates of the death toll, driven heavily by wartime famine, range widely, from roughly 500,000 to as many as 3 million, and remain disputed among historians (Britannica).

Military governments ruled Nigeria for most of the following three decades, interrupted only by the short-lived Second Republic (1979-1983). Civilian, democratic government returned in 1999 under a new constitution, and Nigeria has held competitive elections and transferred power between parties since then, most recently in 2023 (Britannica). Since the mid-2000s, the northeast of the country has faced a prolonged insurgency by the militant group Boko Haram and its offshoots, which has displaced large numbers of people in the region; the situation remains an active security and humanitarian concern (Britannica).

Government and Economy

Nigeria is a federal republic modeled loosely on the U.S. system of separated powers, with an elected president as both head of state and head of government, a bicameral National Assembly (a 109-seat Senate and a 360-seat House of Representatives), and an independent judiciary topped by a Supreme Court. Power is divided among the federal government, 36 state governments, and 774 local government areas (Consulate General of Nigeria, New York).

Nigeria has the largest economy in Africa by several measures and is one of the continent’s leading crude oil producers, holding an estimated 37.5 billion barrels of proven oil reserves; fossil fuel exports remain the country’s primary source of foreign exchange, though output has declined in recent years due to pipeline vandalism, crude theft, and underinvestment (U.S. Energy Information Administration). The World Bank estimated Nigeria’s GDP at about $290.8 billion in 2025, with per capita income around $1,224 and GDP growth of roughly 4 percent, driven increasingly by services, agriculture, and construction rather than oil alone. Inflation eased to about 23 percent in 2025 after peaking above 33 percent the previous year, but poverty remains widespread and a major policy challenge (World Bank).

Culture and People of Nigeria

Nigeria’s population includes more than 250 ethnic groups, of which the Hausa (concentrated in the north), Yoruba (southwest), and Igbo (southeast) are the largest. Its languages belong to three major African language families, Niger-Congo, Afro-Asiatic, and Nilo-Saharan, and English serves as the official language that links the country’s many linguistic communities (Britannica). Religiously, Nigeria is roughly split between a Muslim-majority north and a Christian-majority south, alongside communities that practice traditional indigenous religions, and religion continues to shape regional politics and identity.

Nigerian writers have had an outsized influence on world literature: playwright and poet Wole Soyinka became the first African to win the Nobel Prize in Literature, awarded in 1986, and novelists such as Chinua Achebe and Chimamanda Ngozi Adichie are widely read internationally (The Nobel Prize). Nigeria’s film industry, known as Nollywood, grew from informal, low-budget video production into one of the world’s largest producers of films by volume; a 2009 survey by the UNESCO Institute for Statistics found Nigeria had already surpassed the United States to become the world’s second-largest film producer after India, measured by number of productions (UN News). More recently, Nigerian musicians have driven the international rise of Afrobeats, with artists including Burna Boy, Wizkid, and Davido filling arenas in London and Paris and reaching global streaming audiences; Burna Boy won the Grammy Award for Best Global Music Album in 2021 (LSE Africa Blog).

Nigeria has two inscribed UNESCO World Heritage Sites: the Sukur Cultural Landscape (1999), a well-preserved traditional settlement and terraced farming landscape in the northeast, and the Osun-Osogbo Sacred Grove (2005), a forest along the Osun River near the city of Osogbo that remains an active shrine to the Yoruba goddess Osun and hosts an annual festival (UNESCO World Heritage Centre).

What Is Nigeria Known For?

• Being Africa’s most populous country and one of its largest economies.
• Nollywood, one of the world’s highest-volume film industries.
• Afrobeats, the Nigerian-rooted music genre now heard on global charts.
• A major crude oil producer with substantial proven reserves.
• A deep literary tradition, including Africa’s first Nobel laureate in Literature, Wole Soyinka.
• Extraordinary ethnic and linguistic diversity within a single federal state.

Why Nigeria Matters

Nigeria’s scale alone makes it consequential: it is projected to remain one of the most populous countries on earth through the twenty-first century, and its economic and political stability affects West Africa broadly, from regional trade to migration to security cooperation against groups like Boko Haram. As a major oil exporter, Nigeria’s output and policy decisions have ripple effects on global energy markets. And through Nollywood, Afrobeats, and a long line of internationally recognized writers, Nigeria has become one of the most culturally influential countries on the African continent, shaping entertainment and popular culture well beyond its own borders.
