Disapora

The Alhambra Decree (also known as the Edict of Expulsion) was an edict issued on March 31, 1492 by the joint Catholic Monarchs of Spain (Isabella I of Castile and Ferdinand II of Aragon) ordering the expulsion of Jews from the Kingdoms of Castile and Aragon and its territories and possessions by July 31 of that year.

The edict was formally revoked on December 16,  1968, following the Second Vatican Council.

In 2014, the government of Spain passed a law allowing dual citizenship to Jewish descendants who apply, in order to "compensate for shameful events in the country’s past." Thus, Sephardic Jews who are descendants of those Jews expelled from Spain due to the Alhambra Decree can "become Spaniards without leaving home or giving up their present nationality."

And yes, those are the Isabella and Ferdinand of Christopher Columbus fame. 

As for my own family, you may be asking yourself, "With a name like Watson, you’re Jewish?" It had been Wasserman. My grandfather changed it to Watson not to hide his Jewishness but to avoid the jokes about the Wasserman test. 

So my roots are not Sephardic but Ashkenazic. The Sephardic Jews gave you Maimonides. We gave you Yiddish. Oh, and Albert Einstein. And about 25% of the American Nobel laureates.

You're welcome.
