Kush had lots of gold, copper, and stone. They were rich. Their farmers were also getting good money to. Followed by that, they made the first iron industry. Kush is located north of the Nile River. In fact, Kush was remained an Egypt territory for about 450 years, and wow I would not like that if I was alive back then, and thank goodness because I don't want to live in like the 200 BC.
