Gabon, officially the Gabonese Republic, is a country on the west coast of Central Africa. Located on the equator, Gabon is bordered by Equatorial Guinea to the northwest, Cameroon to the north, the Republic of the Congo on the east and south, and the Gulf of Guinea to the west. It has an area of nearly 270,000 square kilometres and its population is estimated at 2.1 million people. There are three distinct regions: the coastal plains, the mountains, and the savanna in the east. The coastal plains form part of the World Wildlife Fund's Atlantic Equatorial coastal forests ecoregion. Gabon's capital and largest city is Libreville. The official language is French.
Originally settled by Pygmy peoples, they were largely replaced and absorbed by Bantu tribes as they migrated. By the 18th century, a Myeni-speaking kingdom known as the Kingdom of Orungu formed in Gabon. It was able to become a powerful trading center mainly due to its ability to purchase and sell slaves. The kingdom fell with the demise of the slave trade in the 1870s. Since its independence from France in 1960, the sovereign state of Gabon has had three presidents.
