The Converso Online Initiative
Following the massacres that devastated Jewish communities across the Iberian Peninsula, the 1492 Spanish Edict of Expulsion forced all Jews to either leave Spain or. convert to Christianity. In 1497, Portugal forcibly converted the entire normative Jewish community, thus ending 1,500 years of open Jewish life in Spain and Portugal. These mass conversions eventually triggered intense and long-lasting persecution by the Inquisition targeting these newly converted Christians, officially referred to as “New Christians” or “conversos.” They were frequently accused of “Judaizing,” or secretly practicing Jewish rituals and customs despite their outward conversion to Christianity.
A Transformative Initiative: The saga of Sefarad, or the Jews of the Iberian Peninsula, transcends time and space. While the genesis of this story is in Spain and Portugal, the extraordinary consequences have spread across the world, and its impact continues into the 21st century. One of the most profound aspects is the “Converso phenomenon”, which is hundreds of years in the making and is beginning to generate unprecedented interest, curiosity, excitement, quandary, and even controversy. The Converso Phenomenon offers a paradigm shift of biblical proportions and can change the world.
Beginning in the 14th Century, hundreds of thousands of Sefarad Jews lived on the Iberian Peninsula (nowadays Spain and Portugal). Many were forcibly converted to Catholicism (Conversos). Those who attempted to hold on to their Jewish traditions in secret were referred to as crypto-Jews. In later decades and centuries, these hidden or crypto-Jews lived in extreme secret in the hope of not being discovered by the tribunal of the Inquisition, which meant torture and death, often by fire. A substantial presence of this culture can be found in Latin America and the Southwestern part of the United States. Millions of people worldwide are discovering and exploring their Jewish ancestry and seeking a reconnection with their Jewish heritage.
While a few return to their Jewish roots (convert back to Judaism), most stay Christian. However, upon discovering they are descendants of conversos, many embrace their Jewish heritage and feel a greater connection with the Jewish People, Sefarad, and Israel. As there are an estimated 200 million descendants of conversos in the world today, this initiative can truly transform history. The Converso Phenomenon is not just a historical footnote—it is a living, evolving story that continues to shape identities and communities across the globe.
- A 2008 study published in the American Journal of Human Genetics reveals that around 20% of Spanish and Portuguese men carry genetic markers tracing back to Sephardic Jews (Sefarad), indicating a significant portion of the Iberian Peninsula population has ancestral ties to the region's historic Jewish community.
Since this statistic reflects only male lineage, the inclusion of female ancestry would likely increase the overall percentage of individuals with Sephardic roots. This suggests that the number of descendants of Conversos—those converted to Christianity during the Inquisition—is even higher than the study's findings imply.
- Research published in Nature Communications by Chacón-Duque et al. in December 2018 highlights that approximately 25% of Latin Americans exhibit genetic traces potentially linked to Sephardic Jewish ancestry. This points to a widespread presence of Converso heritage among Latin American populations, stemming from Jews who were compelled to convert to Christianity during the Spanish Inquisition and later migrated to the Americas. However, it is important to clarify that not all individuals with this genetic ancestry necessarily identify as Jewish. The study primarily focused on the genetic legacy of Conversos, or Iberian Jews who underwent forced conversion and subsequently settled in the Americas, leaving a lasting imprint on the region's history, identity, and population.
The project is intended to map out, identify, and coalesce millions of converso descendants into an online global community platform. This platform will serve as a hub for individuals to explore and connect to their heritage, access historical and genealogical resources, and engage with experts and fellow descendants. With shared knowledge and connections, it aims to foster cultural rediscovery, identity-building, and historical awareness.
The platform will provide vast amounts of content through which the visitors can discover meaningful and unexpected connections, build rich user journeys, and provide a suite of activities and tools for individual exploration. The tools will provide an interactive deep dive that will enhance understanding of historical and contemporary Judaism, Israel, and Zionism. It will also facilitate research into family histories within a broad historical and cultural context and connect with like-minded individuals and communities around the globe. The platform will feature engaging online and onsite experiences from educators, storytellers, guides, genealogy and family history specialists, spiritual leaders, travel, conventions, concerts, and other creatives.
Connecting the Converso and Latino communities to their Jewish roots: The converso phenomenon has gained popularity in the Hispanic / Latino communities across the American Southwest, Latin America, and Europe. Many believe they are the descendants of conversos and are interested in learning more. This initiative aims to engage with these descendants, and by extension, the Latino communities, and invite them to join an online global community that will assist them in connecting with their Jewish heritage, wherever they may be.
This online community resides in a digital space where people interested in their heritage may find relevant information and connect with people with shared interests, goals, or experiences.
A cornerstone of this project is the enormous amount of content to be made available in researching data covering the past and present. To this end, we are developing a groundbreaking platform, “The Sefarad Virtual Experience”, a first-of-its-kind online environment designed to provide an immersive and interactive exploration of the history of Sefarad. This innovative platform will revolutionize how users engage with historical content by offering a vast array of materials that can be navigated in multiple ways. Interactive maps will trace the journeys and lives of communities and individuals, highlighting key events and narratives spanning the history of Sefarad and beyond.
The platform will be visually captivating and highly interactive, drawing from an extensive collection of digitized resources from Jewish institutions, including museums, libraries, archives, private collections, synagogues, and communities. For the first time, a wealth of materials documenting this pivotal part of Jewish history will be consolidated and organized into a unified, accessible resource using advanced semantic AI technologies. This will create an unparalleled experience for a wide range of users, from the general public to targeted audiences such as students, researchers, and travelers, fostering a deeper understanding and connection to the legacy of Sefarad.
The platform will adopt the concept of a decentralized data space, built of Pods (personal data stores). This approach will foster data sovereignty, inclusivity, and the sustainability of the project and data. From a user perspective, individuals will acquire personal repositories for cultural interests, interacting instantly with hundreds of sources and service providers, resulting in unparalleled levels of personalization and engagement. The emerging network of social connections rooted in common cultural and heritage interests will offer an alternative to today's shallow and superficial connectivity across social networks.
At a time when antisemitism and anti-Israel sentiment are surging out of control, we have a sacred responsibility to act now, and for the future. The Converso Online Initiative is more than a community project — it is a powerful way to combat Jew hatred, educate the world, and critically preserve the vibrant tapestry of the Jewish story for generations to come.
By supporting this unique initiative, you are helping to create a global platform that celebrates Jewish heritage, fosters understanding, and strengthens connections to our shared past. Together, we can ensure that the stories of resilience, faith, and culture are not forgotten but brought to life in many different ways that inspire and unite.
Your contribution, large or small, will empower us to preserve key knowledge, combat woeful ignorance, and stand against bigotry. Join us in safeguarding the Jewish past and shaping a brighter, more informed future. Now is the time to make a difference.
