The first traces of the Nubian kingdom called Kush date to roughly 2,000 B.C. Egyptians conquered parts of the Kushite Kingdom for a few hundred years, and around 1,000 B.C., the Egyptians appear to have died, left, or mixed thoroughly with the local population. At 800 B.C., Kushite kings, also known as the black pharaohs, took over Egypt for a century—two cobras decorating the pharaohs’ crowns signified the unification of kingdoms. And somewhere around 300 A.D., the Kushite empire began to fade away.
