Abuja is the current capital of Nigeria, but the city itself was not always the official seat of government. Before 1991, the capital city was Lagos, which is still a prominent economic hub. Other synonyms for the capital of Nigeria include the Federal Capital Territory (FCT), which encompasses the city of Abuja and its surrounding areas. Some may also refer to it as the political capital, as it is home to the country's top government officials and agencies. Additionally, given Nigeria's vast cultural and regional diversity, many may use the terms "northern capital" or "central capital" to refer to Abuja.
