Nigeria
Nigeria is a federal republic located in West Africa, bordered by Benin to the west, Niger to the north, Chad to the northeast, and Cameroon to the east, with a southern coastline along the Gulf of Guinea. It is the most populous country in Africa and one of the largest economies on the continent.
Nigeria is a federal republic in West Africa, officially known as the Federal Republic of Nigeria. With an estimated population exceeding 200 million people, it is the most populous nation on the African continent and the seventh most populous in the world. The country covers an area of approximately 923,768 square kilometres and encompasses a diverse range of ethnic groups, languages, and ecosystems. Its capital is Abuja, while Lagos remains the largest city and the primary commercial hub.
Geography
Nigeria occupies the eastern portion of the West African bulge, straddling multiple climatic and ecological zones. The far south consists of tropical rainforest and coastal mangroves along the Gulf of Guinea. Moving northward, the terrain transitions through savanna woodland, open grasslands, and eventually semi-arid Sahel scrubland near the borders with Niger and Chad. The Niger River, one of Africa's great rivers, enters the country from the northwest and meets the Benue River near Lokoja before fanning out into the Niger Delta — one of the largest river deltas in the world and a region of significant ecological and economic importance. The Jos Plateau in central Nigeria provides higher elevation and a cooler climate compared to the surrounding lowlands.
History
Pre-colonial Period
The territory now known as Nigeria has been home to complex societies for millennia. The Nok civilisation, which flourished roughly between 1500 BCE and 500 CE, produced some of the earliest iron-smelting technology and terracotta sculpture in sub-Saharan Africa. Later, powerful polities such as the Kanem-Bornu Empire in the northeast, the Hausa city-states in the north, the Oyo Empire in the southwest, and the Benin Kingdom in the south developed extensive trade networks, administrative systems, and artistic traditions. The Benin Kingdom in particular is renowned for its intricately cast bronze sculptures, many of which were removed during the British Punitive Expedition of 1897 and remain the subject of ongoing repatriation debates.
Colonial Period
European contact began in the fifteenth century with Portuguese traders establishing relations along the coast. The transatlantic slave trade profoundly disrupted the region for several centuries. British commercial and political influence expanded significantly during the nineteenth century. The Royal Niger Company was granted a charter in 1886 to administer the Niger River basin. In 1900, the British government assumed direct control, and the country was progressively unified through the amalgamation of the Northern and Southern Protectorates in 1914 under Governor-General Frederick Lugard. Nigeria thereafter functioned as a British colony administered largely through a system of indirect rule.
Independence and Post-Independence
Nigeria gained independence from Britain on 1 October 1960 and became a republic within the Commonwealth of Nations on 1 October 1963. The early post-independence period was marked by political instability and ethnic tension among the country's three dominant groups: the Hausa-Fulani in the north, the Yoruba in the southwest, and the Igbo in the southeast. A series of military coups beginning in January 1966 destabilised the nascent democracy. Tensions culminated in the Nigerian Civil War (1967–1970), also known as the Biafra War, in which the southeastern region declared itself the independent Republic of Biafra. The conflict resulted in an estimated one to three million deaths, many from famine and disease. Nigeria was reunified in January 1970 following the federal government's military victory.
Subsequent decades alternated between military rule and brief civilian administrations. A prolonged oil boom in the 1970s brought significant revenue but also fostered corruption and economic mismanagement. A return to democratic governance was achieved in 1999, when Olusegun Obasanjo was elected president under the Fourth Republic, a constitutional order that has remained in place since.
Government and Politics
Nigeria is a federal republic comprising 36 states and the Federal Capital Territory of Abuja. Executive power is vested in a president who serves as both head of state and head of government. The National Assembly is bicameral, consisting of the Senate and the House of Representatives. The judicial branch is headed by the Supreme Court of Nigeria.
Politics has historically been shaped by regional and ethnic affiliations as well as religion, with predominantly Muslim populations in the north and predominantly Christian populations in the south, though significant minorities exist in both regions. The country has experienced persistent challenges including corruption, electoral irregularities, and security threats. In the northeast, the militant Islamist group Boko Haram has waged an insurgency since approximately 2009, causing widespread displacement and humanitarian suffering. Banditry, farmer-herder conflicts, and separatist agitation in the southeast have also posed ongoing security challenges.
Economy
Nigeria holds the largest economy in Africa by nominal gross domestic product, ahead of South Africa, though rankings can shift depending on methodology and currency fluctuations. The economy is heavily dependent on petroleum, which accounts for the large majority of government revenue and export earnings. Nigeria is a member of OPEC and holds significant proven oil reserves concentrated in the Niger Delta region.
Despite substantial oil wealth, a large portion of the population lives below the international poverty line, reflecting structural inequalities, infrastructure deficits, and governance challenges. Agriculture remains a major employer, with crops including cassava, yams, maize, sorghum, and cocoa. The non-oil private sector, particularly in technology, entertainment (Nollywood — Nigeria's prolific film industry — is among the world's most productive), and financial services, has grown in significance during the early twenty-first century.
Culture and Demographics
Nigeria is one of the most ethnically and linguistically diverse countries in the world, with estimates of over 250 distinct ethnic groups and a comparable number of languages. English serves as the official language and is used in government, education, and formal commerce. Hausa, Yoruba, and Igbo are the three most widely spoken indigenous languages and carry significant regional political weight.
Nigerian culture has had a pronounced global influence. The country's music — encompassing Afrobeats, Jùjú, Highlife, and Afro-fusion — has gained wide international audiences in the twenty-first century. Nollywood produces thousands of films annually and reaches audiences across Africa and among the Nigerian diaspora worldwide.
Religion plays a central role in daily life. Islam is predominant in the north, while Christianity is predominant in the south; traditional indigenous religious practices also persist across many communities.
