Jews adopted matrilineal descent prior to the diaspora...sometime around Augustus I think
btw...
all women were subject to the sexual whims of the nobility and conquerers
not just Jewish women
my own ancestors too I’d reckon
Celts by Romans..
then Pax Romana Britons by Saxons
then Saxons by Danes
then all by Normans and so forth
I’ve seen studies that Med peoples were fairer in Biblical times than now....Romans and Greeks for sure and Phonecian type and Jews too possibly..who knows
I would take a gander and say that was because of the conquering Ottomans...
