Current Coptic Egyptians (10% of the population) are the descendants of the Pharaohs; the majority of Egyptians today are the result of the Arab invasion (when Arabs spilled out of the peninsula and made their way across North Africa, eventually invading & holding much of Spain). Tribes like the Berbers were the previous North African populations.
From Wikipedia:
“They also associate the Coptic component with Ancient Egyptian ancestry, without the later Arabian influence that is present among other Egyptians.”
Thanks, I did not know that.
