"The territory of modern Central African Republic is known to have been settled from at least the 7th century on by overlapping empires..."

"... including the Kanem-Bornu, Ouaddai, Baguirmi, and Dafour groups based on the Lake Chad region and along the Upper Nile. Later, various sultanates claimed present-day CAR, using the entire Oubangui region as a source of slave, from which slaves were traded north across the Sahara Desert."

Today's "History of" country is the Central African Republic.
