Sephardic Bnei Anusim is a modern term which is used to define the contemporary Christian descendants of an estimated quarter of a million 15th-century Sephardic Jews who were coerced or forced to convert to Catholicism during the 14th and 15th centuries in Spain and Portugal. The vast majority of conversos remained in Spain and Portugal, and their descendants, who number in the millions, live in both of these countries. The small minority of conversos who emigrated normally chose to emigrate to destinations where Sephardic communities already existed, particularly to the Ottoman Empire and North Africa, but some of them emigrated to more tolerant cities in Europe, where many of them immediately reverted to Judaism. In theory, very few of them would have traveled to Latin America with colonial expeditions, because only those Spaniards who could certify that they had no recent Muslim or Jewish ancestry were supposed to be allowed to travel to the New World. Recent genetic studies suggest that the arrival of the Sephardic ancestors of Latin American populations coincided with the initial colonization of Latin America, which suggests that significant numbers of recent converts were able to travel to the new world and contribute to the gene pool of modern Latin American populations despite an official prohibition on them doing so. In addition, later arriving Spanish immigrants would have themselves contributed additional converso ancestry in some parts of Latin America.
