Describe the rise and decline of nubia

 Nubia ran into a problem when the demand for iron grew. They had to burn wood to make iron, and they used up most of their wood. The demand for iron was growing, but Nubia could not produce as much iron as they had in the past. Traders began to look at other countries for iron and as trade went down, the country began to weaken, then causing the later destruction of The Nubian civilizations. Egypt has taken over Nubia, which is now Egypt territory. The Ancient Nubian people and their land are gone.
