The Buduma traditionally claim to be descended from the peoples of the Sao civilization and Kanem-Bornu Empire.
During this time (specifically around the 9th to 16th centuries), many ethnic groups in the area assimilated or merged in consequence of the new political power in the region.

The reeds are used for constructing fishing boats, lightweight huts (that can be moved to higher ground if the lake rises), and more.
