The vast majority of Spain's "conversos", however, remained in Spain and Portugal and were suspected of "Marranism" by the Spanish Inquisition. Although the wealthier among them could easily bypass discriminatory "Limpieza de sangre" laws, they constituted a significant portion of the over three thousand people executed for heresy by the Spanish Inquisition. In his luminous book the "Marrano Factory: The Portuguese Inquisition and Its New Christians 1536-1765", Professor Antonio Jose Saraiva [https://pt.wikipedia.org/wiki/Ant%C3%B3nio_Jos%C3%A9_Saraiva] of the University of Lisbon, writes that "After August 1531, when the establishment of the Inquisition in Portugal was in the offing and especially after June 14, 1532 when New Christian emigration from Portugal became a capital offense, anti-New Christian sentiment surged on all sides. The New Christians were panic-stricken and emigrants, legal or clandestine, headed for Flanders, Italy, the Ottoman Empire, the Portuguese possessions in India, North Africa. After the middle of the century, England, France, the Spanish Americas and Brazil were the favorite destinations, not necessarily in that order." The New Christians breathed more freely when Philip III of Spain came to the throne. By the law of April 4, 1601, he granted them the privilege of unrestricted sale of their real estate as well as free departure from the country for themselves, their families, and their property. Many, availing themselves of this permission, followed their coreligionists to North Africa and Turkey. After a few years, however, the privilege was revoked, and the Inquisition resumed its activity.
