Historical Background

Gabon, a sparsely populated country known for its dense rainforests and vast petroleum reserves, is one of the most prosperous and stable countries in central Africa. Approximately 40 ethnic groups are represented, the largest of which is the Fang, a group that covers the northern third of Gabon and expands north into Equatorial Guinea and Cameroon. From about the early 1300s, various kingdoms emerged in present-day Gabon and the surrounding area, including the Kingdoms of Loango and Orungu.
