Tiye was not a “commoner” but the daughter of a military man. She just wasn’t part of the royal family.
Nor was she probably a “Full blood” nubian: Most Nubian mercenaries were integrated into Egyptian society, and since her family lived in the Delta one suspects her mom was a local gal.
In the olden days, the “nubian” part was ignored in history, but now the powers that be go overboard in pushing the Black connection...which was considerable, but not as much as some insist.
Like Obama, Akhenatan was probably a “mulatto”.
And both had Nilic, not Bantu, blood: Hence the long face (vs the rounder face of most Bantu Africans)...
what’s the difference between Nilic and Bantu? I’m a little hazy on non-Caucasoid history and differences
