Marrano (Spinoza)

(In medieval Spain) a Jew or Moor who had converted to Christianity, especially one who professed conversion in order to avoid persecution.

• Marranos is one of the terms used in relation to Spanish and Portuguese Jews who converted or were forced by the Spanish and Portuguese crowns to convert to Christianity during the fifteenth and sixteenth centuries, but continued to practice Judaism in secrecy or were suspected of it, referred to as Crypto-Jews. "Crypto-Jew" is the term increasingly preferred in scholarly works, instead of Marrano.  https://en.wikipedia.org/wiki/Marrano
