The Sahara desert functioned as a navigable route network rather than a barrier

Evidence

The Sahara is not a barrier. It is a route system. From approximately the third century CE, when the camel reached the Maghreb, the Sahara became a navigable space — operationally connecting the Mediterranean north to the Sahel south through approximately five corridors. The western corridor: Sijilmasa to Awdaghust to the Soninke kingdom of Ghana. The central corridor: Ghadames to Agades to Hausaland. The eastern corridor: the Fezzan to the Lake Chad basin, the territory of the Kanem-Bornu Empire. Across these corridors moved gold, salt, copper, ivory, kola, slaves — and, from the seventh century onward, Islam. — , The Rod and the Child, 4308
