Detailed explanation-1: -For nearly 3, 000 years a series of kingdoms flourished in ancient Nubia (present-day southern Egypt and northern Sudan). The region was rich in sought-after resources such as gold and ivory and its trade networks reached Egypt, Greece, Rome, and central Africa.

Detailed explanation-2: -As warriors, the ancient Nubians were famous for their skill and precision with the bow and arrow. In the Middle Ages, the Nubians converted to Christianity and established three kingdoms: Nobatia in the north, Makuria in the center, and Alodia in the south.

Detailed explanation-3: -In the deserts, Nubians mined carnelian and gold, as well as other mineral resources.
