Fascinating what you can find online:
Mrs Jones, DNA analysis of medieval Iberian Moorish remains show only a small contribution from sub-saharan haplogroups.
That is worth a great deal more than historical interpretation.
It is also more scientifically valid than afrocentric historical revisionism.
In other words, there weren't many black people in Spain during the period of Islamic domination.
They were mostly Berbers, with a largish Arabic contingent.
"Moor" came to be used to describe Muslims in general, and people of darker skin, whether or not they were what we today call "black."
Even ethnic Spaniards of that time, if they were Muslim, were called "Moros."
When Spain took the Philippines as a colony, the Muslim part of the population to the south were called "Moros." This isn't because they were darker skinned than the others.
Today, Spanish, we call black or black-mixed, or dark skinned people "moreno."
It isn't limited to black people.
I've seen Mexican personal documents, where someone of darker skin due to native ancestry has their skin color described as "tez morena."
Here is a reference for you:
Unfortunately I can’t find the diagrams for this piece. This shows a larger Arab and Berber than the other study I’ve seen into this. I shall have to have another look at it. Notably, for all you Afrocentrists who think Moors were black Africans, there are only Arab and Berber Y chromosomes found. Sub Saharan ancestry only shows up at trace in these studies.
