How did the Egypts location both limit and invite interaction with other cultures

The hypothesis of the existence of bordering pepoples who, through a spatial dialectical process with the Egyptians, were defining the birders of the pharaonic state.

When talking about the borders in Ancient Egypt we have to differentiate at least two types.

One was political borders. An another was the characteristics of the Egyptian territory, the natural limits between the valley and the desert.

They hardly had any contact with outside word and that, therefore, their relationship with other cultures was vert scarce.
