History

According to some modern historians, of all the regions of Africa, western Sudan "is the one that has seen the longest development of agriculture, of markets and long-distance trade, and of complex political systems." It is also the first region "south of the Sahara where African Islam took root and flowered."

Middle Ages

in the fifteenth century, "people were directed to the Atlantic slave trade," totaling over a thousand years for the Saharan and four centuries for the Atlantic trades. As a result, slavery critically shaped the institutions and systems of the Sudan. The Portuguese first arrived at Senegambia and found that slavery was "well established" in the region, used to "feed the courts of coastal kings as it was used in the medieval empires of the interior." Between the process of capture, enslavement, and "incorporation into a new community, the slave had neither rights nor any social identity." As a result, the identity of people who were enslaved "came from membership in a corporate group, usually based on kinship."Klein 1998, p. 1-2.

Modern

During the period of European colonization, French Sudan was created in the area that would become Mali and

was formed in what would become the present Sudanese and South Sudanese states.
