A comprehensive study of the New Christian elite of Jewish origin--prominent traders, merchants, bankers and men of letters--between the fifteenth and eighteenth centuries The New Christian elite of Jewish origin were at the forefront of early modern globalisation from the fifteenth to the eighteenth centuries. Either forced to convert to Christianity or descended from those who were, these Iberian traders, merchants, and bankers with links to the academic world and liberal professions played a pivotal role in intercontinental trade for two centuries--only to decline, and virtually disappear as an ethnic elite, by the mid-1700s. In Strangers Within, Francisco Bethencourt offers a comprehensive study of the New Christian trading elite, describing their many achievements, innovations and migrations. Members of this new elite were instrumental in opening global trade, investing in plantations and industries and loaning money to kings, popes, cardinals, noblemen and religious orders. They lived under constant threat of the Inquisition for almost three hundred years, yet most of them stayed in the Iberian world. Others departed to create Sephardic communities in north Africa, the Ottoman Empire, northern Europe and the Americas. Drawing on new research in archives and research libraries in Lisbon, Madrid, Seville, Simancas, Rome, Florence, Antwerp, London and Lima, Bethencourt traces the international networks New Christian trading elite families built, the different religious allegiances they assumed and the wide range of places in which they carried on their business activities. He describes the prominent roles they played in Iberian and European culture: Saint Teresa de Avila had a New Christian background, as did the philosopher Spinoza. Despite their prominence, after three centuries, the New Christians disappeared as a recognizable ethnicity, finally bowing under the accumulated weight of racism and persecution.
