Documented Jewish presence in Northwestern Iberia dates back, at least, to the 10th century. In Spain, however, minimum, to the first century of the Common Era. This is a population that went through exclusions, prohibitions, persecutions, forced conversations, and expulsions in 1483 (Andalucia), 1492 (Leon, Castile and Aragon), Portugal (1497) and the Kingdom of Navarre (1498). These tragic events produced two main outcomes, the Jewish Sephardic Diaspora, and the converso and/or marrano and Crypto Jews. They both have the same documented Hebrew origin in the Iberian Peninsula. The Sephardic Diaspora settled in every corner of the planet, interacting, intermarriaging, and living for centuries among other cultures. This group interest is to trace that story through historical, cultural and genetic journeys around the world in connection with the Zamora (Spain) - Tras Os Montes (Portugal) region, expanding, deepening, and enriching members's personal and collective memory.
