Suppose for whatever reason that Christian missionaries successfully evangelize in the Senegal-Niger watershed in the time period stated in the thread title. The empire of Ghana coalesced during this time period and commanded great wealth from trading in gold, copper, and salt.

Does Christianity accelerate state formation in West Africa or simply exist as neutral aspect with little impact on political events? How well would Latin literacy spread ITTL compared to the spread of Arabic literacy IOTL?
