No I mean I wasn’t including the earlier Crusades that might have affected the Sephardic Jews in Spain and Portugal, I was thinking Rhineland Jews would be of the Ashkenazis variety but according to this study they apparently didn’t exist back then (in 1096). Anyone have a link to the scientific paper, I’m also curious as to what statistical sampling methods were used.
for the misunderstanding. Got it; but according to the seemingly complete article in wiki here https://en.wikipedia.org/wiki/Ashkenazi_Jews, they arose in the early medieval period in the 5th to 10th century.
