Answer:
They were important trading partners. Egypt imported gold, ivory, iron and slaves from Kush, while Kush bough cotton and wheat from Egypt.
Step-by-step explanation:
Egypt and the kingdom of Kush in Nubia had developed the trading process and were dependent on each other economically for various goods. The trade was made over the river Nile, as well as on land, by using camels.
The Kush Kingdom was rich in luxuries, so Egyptians bought iron, ivory, skins, gold, slaves, and incense from them. They would also sometimes provide Egypt with exotic animals and their goods, giraffes, elephants, and ostrich feathers, often used by the pharaoh family.
Kush got cotton and wheat from Egypt directly but also imported olive oil coming from Lebanon over their routes and traders.
