In 1492, the Catholic Monarchs decreed the expulsion of all Jews from Spain. Those who refused baptism lost their homeland. Those who converted -- the conversos -- kept their homes but not their freedom: the Inquisition watched them, the Blood Purity Statutes excluded them, and suspicion followed them for life. Many crossed the Atlantic seeking what the Peninsula no longer offered: distance.
New Spain was, from the beginning, a destination for conversos. They arrived with the conquistadors, settled as merchants and colonizers, founded cities in the northeast and western Mexico. Some abandoned all Jewish practice; others maintained it in secret for generations, becoming what the Inquisition called judaizantes -- and what history remembers as crypto-Jews.
This site reconstructs that history: the families who lived it, the regions where they settled, the inquisitorial trials that documented it unwittingly, the customs that survived without explanation, and the genetic evidence that today confirms what the archives suggest. Five centuries of hidden faith, traced through documents, DNA, and genealogy.
Why they had to hide
Conversion was not enough. The Blood Purity Statutes -- enforced in Spain and transplanted to the viceroyalty -- required proof that a family had no Jewish or Muslim ancestry. Without that proof, a converso could not marry freely, join guilds, attend university, or hold public office. The stain of blood was inherited as a perpetual sentence.
The Inquisition reinforced the system with active surveillance. Any suspicion -- a neighbor who noticed a dark house on Saturday, a kitchen without pork, a burial with unusual practices -- could trigger a denunciation. And every denunciation could unleash a chain of interrogations, torture, and betrayals that destroyed entire families.
Facing that reality, the conversos developed extreme survival strategies. Some left their children at church doors to be raised as Catholics, cutting the trace of Jewish blood in a single generation. Others relocated to the most remote provinces of the viceroyalty -- the Nuevo Reino de Leon, Zacatecas, the northern frontier -- where the arm of the Inquisition reached with less force. And many simply lived the double life the system imposed on them: Catholic in public, Jewish in the privacy of their homes.
