WEST AFRICA (WESTERN SUDAN) West African/Western Sudanic cities. None appear on Chandler's list through AD 622. Thereafter the picture (with sporadic supportive or alter- native readings from other workers) is: Size Lower limit AD 800 Gao 72,000 Ghana 30,000 Awdaghost no estimate none Sijilmessa (Morocco) at 24,000 may also be mentioned as the nearest trans-Saharan city to West African civilization on Chandler's city lists. Sijilmessa became an important political and economic center around AD 780. (Lewicki, 1988:280) It would be reasonable to suppose that this was due to a trans-Saharan trade, and therefore that at least one similar prosper- ous sub-Saharan urban terminus must have arisen no later than this time.Songhay began trans-Saharan trade with Tahert, Algeria in the mid-8th century, and developed the trade town of Gao north of the old capital Kukiya.
