Abuja — Capital of Nigeria

Abuja is one of the world's clearest examples of a purpose-built capital: unlike Lagos, the sprawling coastal city that served as Nigeria's capital from independence in 1960, Abuja did not exist as a city at all until construction began in the late 1970s on land that had previously been sparsely populated, largely rural territory in what is now the Federal Capital Territory, carved out of parts of Niger, Kwara, and Plateau states in 1976.

The decision to relocate the capital was driven by a mix of practical and political reasoning that emerged strongly after Nigeria's brutal 1967–1970 civil war: Lagos was overcrowded, its port-city geography constrained further growth, and — most pointedly — it was widely perceived, fairly or not, as identified with the Yoruba southwest and the country's colonial coastal elite, a perception federal planners wanted to move away from in a country whose deepest political fault lines run along ethnic and regional lines. Abuja's location near the geographic center of the country, at the boundary of the mainly Muslim north and mainly Christian south, was explicitly chosen as neutral ground not strongly identified with any single major ethnic group.

Planning began under the military government of General Murtala Mohammed, who was assassinated in a failed coup in February 1976 before the project he championed was completed; construction proceeded through subsequent military and civilian governments over the following decade and a half, and Abuja was formally inaugurated as Nigeria's capital on 12 December 1991, with government offices relocating from Lagos over the following years.

The city's master plan, developed by international consultants including the Tokyo-based firm associated with architect Kenzo Tange, laid out Abuja in organized districts radiating from Aso Rock, a distinctive 400-meter granite outcrop that dominates the skyline and gives its name to the Aso Rock Presidential Villa, Nigeria's seat of executive power, built at its base.

Abuja is also notable for a deliberate architectural gesture toward the country's religious balance: the National Mosque and the National Ecumenical Centre (a major Christian worship and conference center) sit facing each other across the same central axis of the city, a placement widely read as a symbolic statement of religious parity in a country roughly split between a Muslim-majority north and a Christian-majority south.

As a planned city built from scratch, Abuja has grown rapidly since the 1990s well beyond its original master-plan boundaries, drawing civil servants, diplomats, and, increasingly, private businesses relocating from Lagos, giving it — unusually for a purpose-built capital — a genuinely large and still-expanding resident population rather than remaining a purely administrative enclave.

That rapid, largely unplanned growth beyond the original master plan has also produced a persistent gap between Abuja's formal, well-serviced central districts and large satellite settlements on the city's outskirts, home to a substantial share of the metro area's population but often lacking the infrastructure the original 1970s master plan provided for — a tension that has made Abuja's development a recurring subject of Nigerian urban-policy debate since the 2000s.

The city hosts Nigeria's National Christian Centre and National Mosque along the same central axis, and it is also home to the National Assembly complex, whose green-domed twin towers, completed in the early 1990s, are among the most recognizable government buildings in West Africa, housing both chambers of Nigeria's bicameral federal legislature.
