 These Crypto-Jews were known as New Christians, and would be under the constant surveillance of the Inquisition – to such an extent that most of these, would eventually leave the country in the centuries to come and again embrace openly their Jewish faith, joining the communities of Spanish and Portuguese Jews in places like Amsterdam, London or Livorno.Some of the most famous descendants of Portuguese Jews who lived outside Portugal are the philosopher Baruch Spinoza (from Portuguese Bento de Espinosa), and the classical economist David Ricardo.Very few Jews, the Belmonte Jews, went for a different and radical solution, practicing their faith in a strict secret isolated community.
