Politically, Nigeria is divided into thirty-six states.
The nation's capital was moved from Lagos, the country's largest city, to Abuja on 12 December 1991.
Today it is often used in ethnically mixed urban areas as a common form of communication among people who have not had formal education in English. Because there is little feeling of national unity among Nigeria's people, there is little in terms of national symbolism.
What exists was usually created or unveiled by the government as representative of the nation. The flag is divided vertically into three equal parts; the center section is white, flanked by two green sections.
Nigeria has three main environmental regions: savanna, tropical forests, and coastal wetlands.
