Mexicans originating from Sephardic decent. Originating in the Iberian Peninsula (Portugal and Spain), including the descendants of those subject to expulsion from Spain by order of the Catholic Monarchs Ferdinand and Isabella (as codified in the Alhambra decree of 1492), or from Portugal by order of King Manuel I in 1497.
The name comes from Sepharad, a Biblical location.1 This was probably the "Saparda" mentioned in Persian inscriptions: the location of that is disputed, but may have been Sardis in Asia Minor. "Sepharad" was identified by later Jews as the Iberian Peninsula, and still means "Spain" in modern Hebrew.
