The pyramids of Nuri
Nastasen’s watery tomb is located at the ancient site of Nuri, which sprawls across more than 170 acres of sand near the east bank of the Nile River in northern Sudan.
These pyramids mark the burials of Kushite royals, the “black pharaohs” who operated as vassals on the gold-rich southern edges of the Egyptian empire, but who emerged as a force of their own during the political chaos that followed the demise of the New Kingdom.
From about 760 B.C. to 650 B.C., five Kushite pharaohs ruled all of Egypt from Nubia to the Mediterranean Sea, embarking on ambitious building programs up and down the Nile and reviving the religious practices of a much earlier Egyptian empire—including the construction of pyramids, which they buried their kings under.
There do appear to have been some black pharaohs.
Sudan was not a source country for American slaves.
If you look at the source countries, they did have kings, and they sold their slaves and captives from neighboring lands to the trans-Atlantic trade.
The Kushites lasted for ninety years, and had 5 rulers in that short span of time, and were never strong enough to hold onto their territory for very long...................
The Jollofs tribe, on the west coast of Africa, were noted for attractiveness. Charles Darwin asked them how they thought that came to be. He was told they sold the ugly women (presumably to go to the New World)
