Maybe we really are all Sephardic! After all, those who call themselves Sephardic are not just those from the Iberian peninsula (Sepharad was the Hebrew name for Spain), but most of the Jews of the Mediterranean world reaching east to India — and they were the ancestors of Ashkenazim.
For centuries, Sephardic-Mizrahi Jews of Arab lands lived in relatively peaceful coexistence with their Arab-Muslim neighbors. While never perfect, life for Jews in Arab lands was not characterized by the horrible persecutions, pogroms or expulsions regularly experienced by Jews living under Christian rule in Europe. Indeed, the Golden Age of Spain took place under Islamic rule, and only after the Catholics re-conquered Spain from the Muslims were Jews subject to the brutal inquisition and subsequent expulsion from Spain in 1492.
