New Christian

New Christian (Latin: Novus Christianus; Spanish: Cristiano Nuevo; Portuguese: Cristão-Novo; Catalan: Cristià Nou; Ladino: Kristiano Muevo; Arabic: المسيحيون الجدد) was a socio-religious designation and legal distinction referring to the population of former Jewish and Muslim converts to Christianity in the Spanish and Portuguese empires, and their respective colonies in the New World.

Subsequently, the Spanish Inquisition first and then the Portuguese Inquisition was created to enforce Catholic orthodoxy and to investigate allegations of heresy. This became a political issue in the kingdoms of the Portuguese–Spanish Union itself, and their respective empires abroad, particularly in Spanish America, Portuguese America, and the Caribbean. Sometimes "New Christians" travelled to territories controlled by Protestant enemies of Spain, such as the Dutch Empire, the early English Empire, or Huguenot-influenced areas of the Kingdom of France such as Bordeaux, and openly practiced Judaism, which furthered suspicion of Jewish crypsis. Nevertheless, a significant number of those "New Christians" of Converso ancestry were deemed by Spanish society as sincerely Catholic and they still managed to attain prominence, whether religious (St.
