Alhambra Decree
After the Alhambra Decree of the expulsion of the Jewish population from Spain in 1492 and a similar Portuguese decree in 1497, the remaining Jewish population in Iberia became officially Christian by default. The New Christians, especially those of Jewish origin, were always under suspicion of being "judaizantes" ("judaizers"), that is, apostatizing from the Christian religion and being active crypto-Jews.
