sangre statutes instituted legal discrimination against converso descendants, barring them from certain positions and forbidding them from emigrating to the Americas. For years, families with urban origins who had extensive trade connections, and people who were learned and multilingual were suspected of having Jewish ancestry. According to the prejudice of the time, a person with Jewish blood was untrustworthy and inferior. Such measures slowly faded away as converso identity was forgotten and this community merged into Spain's dominant Catholic culture. This process lasted until the eighteenth century, with a few exceptions, most notably the Chuetas of the island of Majorca, where discrimination lasted into early 20th Century. A Y chromosome DNA test conducted by the University of Leicester and the Pompeu Fabra University has indicated an average of nearly 20% for Spaniards having some direct patrilineal descent from populations from the Near East which colonized the region either in historical times, such as Jews and Phoenicians, or during earlier prehistoric Neolithic migrations. Between the 90,000 Jews who converted under the Visigoth persecutions, and the 100,000+ Jews who converted in the years leading up to expulsion, it is likely that many of these people have Jewish ancestry. Genetic studies have explored local beliefs in the American South West that Spanish Americans are the descendants of conversos. Modern Spanish policy The Spanish government has actively pursued a policy of reconciliation with the descendants of its expelled Jews. In 1924, the regime of Primo de Rivera granted the possibility of obtaining Spanish citizenship to a part of the Sephardic Jewish diaspora. As stated above, the Alhambra decree was officially revoked in 1968, after the Second Vatican Council rejected the charge of deicide traditionally attributed to the Jews. In 1992, in a ceremony marking the 500th anniversary of the Edict of Expulsion, King Juan Carlos (wearing a yarmulke) prayed alongside Israeli president Chaim Herzog and members of the Jewish community in the Beth Yaacov Synagogue. The King said, "Sefarad (the Hebrew name for Spain) isn't a nostalgic memory anymore; it is a place where it must not be said that Jews should simply 'feel' at home there, for indeed Hispano-Jews are at home in Spain...What matters is not accountability for what we may have done wrong or right, but the willingness to look to the future, and analyze the past in light of our future."
