Nubia rivaled Egypt for control over land.
Explanation:
Egypt and Nubia were two ancient civilizations that were neighboring each other. Egypt was located in the lower flow of the Nile River, while Nubia was located in the middle flow of the Nile River. At one point, both civilizations were strong and well developed, and while there was lot of collaboration between the two, there were also tensions. The tensions mainly came because of the rivalry over the trade routs and the land which both needed, especially Egypt.
- The majority of the trade from sub-Saharan Africa was going through Nubia, and the Nubians had set some taxes on the trade goods so that they make more wealth.
- The Egyptians didn't fancied that fact that they were paying taxes to Nubia, and they wanted to get hold onto the trade routes and control them themselves, thus they wanted the land for themselves.
- Over time, the rivalry over the trade routes and the demand for new land escalated and Egypt and Nubia got into a conflict, with the Egyptians being the victorious side and making a monopoly when it came to trade between sub-Saharan Africa and North Africa.
- The new land was desired in big part because the Nile River provided lot of fertile land for large scale agriculture, and with the growing population more and more food was needed.
