The Gao Empire preceded the Songhai Empire in the region of the Middle Niger. It owes its name to the town of Gao located at the eastern Niger bend. In the ninth century CE, it was considered to be the most powerful West African kingdom. There are no surviving indigenous written records that date from before the middle of the 17th century. Our knowledge of the early history of the town relies on the writings of external Arabic geographers living in Morocco, Egypt and Andalusia, who never visited the region.
