- How did their interdependence work (question 1)
Egypt limited the south with Kush or Nubia, where today the region of El Sudan is located. Egyptian texts talk about the expeditions to Nubia, but it was in the era of the Middle Kingdom of Egypt that they conquered.
In the eighteenth year of the reign was conducted a campaign against Nubia in which the name of Kush is mentioned for the first time. The conquest was at this purely military stage: control of resources and creation of a area controlled by numerous fortifications.
In the Second Intermediate Period of Egypt (between 1780 to 1580 BC) the Egyptians lost control of the area: the Nubians were liberated and destroyed the forts and reconquered the country.
- Why did each take control of the other in turn (question 2)
Both towns wanted to conquer the territory that borders the Nile. The river was a source of water and life and an ideal space for the people. Kush was a region located along the valley of the Nile that included the south of Egypt and extended by the north of Sudan. It was a profitable land raw materials, especially in gold, so the Egyptians very early ambitioned to exploit these resources.
