David Reubeni’s Visit to Portugal and the Rise of Messianic Hopes (1525–1526)

In November 1525, David Reubeni, a mysterious Jewish traveler and diplomat, arrived at the court of King John III of Portugal in Almeirim. His mission was to secure Portuguese military aid for a Jewish campaign to reclaim the Holy Land, an ambitious and messianic vision that quickly attracted attention—and controversy.


David Reubeni’s Proposal to King John III

  • Jewish communities privately raised funds to support Reubeni’s travels and negotiations.
  • Reubeni requested military assistance from Portugal, claiming to represent a powerful Jewish kingdom in Arabia, ruled by his brother.
  • King John III, initially intrigued, promised him:
    • Eight ships and 4,000 cannons to aid in his mission.
  • However, the king faced significant political and religious pressures, as Portugal was actively persecuting suspected Marranos (crypto-Jews) under the Inquisition.
  • During negotiations, King John III temporarily halted his repression of conversos, a move that excited and emboldened Jewish and crypto-Jewish communities.

Reubeni’s Influence and the Emergence of Solomon Molcho

  • Diego Pires, a noble converso youth, was deeply inspired by Reubeni’s presence.
  • Under Reubeni’s influence, he abandoned Christianity and embraced Judaism, taking the name Solomon Molcho.
  • Molcho began to preach messianic prophecies, attracting followers and raising concerns among the authorities.

Growing Jewish Activity and Official Backlash

  • Jewish envoys from the Barbary States arrived at the Portuguese court to meet with Reubeni, further fueling excitement and suspicion.
  • Some enthusiastic conversos staged an armed uprising near Badajoz, where they:
    • Freed a converso woman from the Inquisition.
    • Challenged Portuguese authorities, demonstrating their hope for Jewish deliverance.
  • Alarmed by the growing unrest, Portuguese officials began to see Reubeni as a threat rather than an ally.

Consequences and Growing Suspicion

  • Portuguese authorities became deeply concerned that Reubeni’s mission could destabilize the kingdom by inciting Marranos and conversos to rebellion.
  • King John III, fearful of unrest and the Inquisition’s influence, withdrew his support for Reubeni.
  • Reubeni’s mission, once a diplomatic possibility, now turned into a political liability.

Conclusion: A Mission That Shook Portugal’s Crypto-Jews

David Reubeni’s arrival in Portugal in 1525 sparked a wave of messianic enthusiasm among Jewish and converso communities, temporarily stalling Inquisitorial persecution. However, as unrest grew, the Portuguese monarchy turned against him, fearing that his mission posed a threat to the stability of the realm.

His journey, though ultimately unsuccessful, inspired Jewish resistance, led to the rise of Solomon Molcho, and demonstrated the fragile position of Portugal’s New Christians under John III’s reign.
