How much are Egyptians Arabs?
Not for any particular reason but just pondering. In the same sense that we English are a mixture, Celt, Anglo Saxon, Jute, Viking, Norman and so on. But there’s a very great chunk of it that is still Celt. The rulers may have come in but the population (perhaps, at times, only the female) endured.
And with Egypt. How much are they Arabs, from the conquest, and how much Egyptians from before?
And, actually, I could imagine that the Circassian and Alan genetic influence is greater than the Arab. Imagine that is, not prove. For the Mamluk armies etc were all recruited, first generation, from the steppes as slaves. And children of them could not join the army at all, or administration, so must have gone off into the general population. So I could imagine that that influence was greater than the Arab.
