Nubian people The Nubians are an ethnic group originally from northern Sudan, and southern Egypt. The Nubian people in Sudan inhabit the region between Wadi Halfa in the north and Al Dabbah in the south.
The most prosperous period of Nubian civilization was that of the kingdom of Kush, which endured from about 800 BC to about 320 AD. During this time, the Nubians of Kush would at one point, assume rule over all of Nubia as well as Upper and Lower Egypt.
