In fact, the logic was obvious upon reflection. If the Nile River Basin had been even remotely suitable for human habitation, Egypt or other North African civilizations would have moved south long ago. And from the distribution map of the Arab religion in Africa, it was clear that they had instead interacted more frequently with West Africa. West Africa had a whole host of Black nations and tribes that believed in the Arab religion, further proving just how harsh the environment was in the zone where East Africa and North Africa met.
Of course, aside from climatic factors, the ancient African natives had not actually been as easy to bully as imagined. At least in the age of cold weapons, even the relatively backward Black peoples had the strength to fight the Arab civilization of North Africa.
In East Africa's Nile Province, the more economically developed areas were precisely the northern desert regions. As for the south, aside from a few cities, there was basically very little population.
The specific reasons, aside from the harsh climate, included the frequent flooding in the southern regions. Just imagine it: the Nile River Basin already had a rainy season, while during that same period, river water from the rainy season in the upstream Great Lakes Region also drained here. Naturally, the likelihood of local flooding was even higher.
After the rainy season, the Nile River Basin was prone to drought again, making it a cycle of repeated torment. Thus, East Africa's development of Nile Province had always lagged behind.
Ernst said of this, "The climate across all of northern East Africa is harsher than in the central and southern regions, and it has no great resource advantages either. Therefore, the Great Lakes Region is the habitable zone closest to the north. Naturally, you
