What makes the capital of nigeria different from other capitals in west africa?

Abuja is the capital of Nigeria in West Africa, Africa's most populous nation. Just under 800,000 people live in Abuja (less than a tenth that live in Lagos, the old capital). Abuja is a planned city, it became Nigeria's capital city in 1991 and it's situated in the center of the country. Many developing nations have planned capital cities situated in the geographic center in order to maintain some political neutrality as well as create an economic base in a previously underdeveloped part of the country. :)
