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.
Technically speaking, Nubia can refer to either a region or to an ancient civilization, each of which occupy roughly the same overlapping space. Nubia lies along the east and west banks of the Nile River near the modern-day border of southern Egypt and northern Sudan.
