The Egyptians did not view the Nubians as "negroes", first and foremost. That would be the equivalent of saying that the Navajo Indians viewed the Aztecs as "chicanos". Such terms were not coined until much later in history, particularly during colonial times when racism was inherent in white society. There is no word in the Egyptian language for "negro", in the racial sense at least.
When assuming from Ancient Egyptian references to the land of Kush, for example, it is therefore wrong to translate it as "land of the negroes" (as Arthur Kemp has done in his so-called "History of the White Race"). The proper wording is more likely "land of the Nubians", as the Egyptians viewed most people south of their borders. It is important to remember that the word "negro" did not exist in those times among the Ancient Egyptians or the Kushites.
