Empire of SonghayFrom Encyclopedia of African History
The largest of the three great West African empires of the later Iron Age, [the Songhay Empire] flourished between the mid-fifteenth and late sixteenth centuries, but the foundations were laid some hundreds of years earlier. Today, the Songhay are the dominant ethnic group in the vicinity of Gao and their fortunes are intimately associated with the River Niger, especially in the area known as the Niger Bend, encompassing eastern Mali and northwestern Niger.
