March 31
Spain Issues Alhambra Decree Expelling Jews
Catholic Monarchs Ferdinand II of Aragon and Isabella I of Castile signed the Alhambra Decree on March 31, 1492, ordering Spain's remaining unconverted Jews to depart their realms by July's end or convert to Christianity.
Summary
Following the completion of the Reconquista with the fall of Granada in January 1492, Catholic Monarchs Ferdinand II of Aragon and Isabella I of Castile sought to consolidate religious unity in their realms. Years of the Spanish Inquisition had already pressured many Jews to convert to Christianity, creating a large population of conversos suspected of secretly practicing Judaism. On March 31, 1492, the monarchs signed the Alhambra Decree in Granada, ordering all unconverted Jews to leave Castile and Aragon by the end of July or face severe penalties. The edict aimed to eliminate perceived Jewish influence on conversos and prevent crypto-Judaism. Thousands chose conversion to stay, while an estimated 40,000 to 100,000 departed, leading to the immediate dispersal of Spain's Jewish communities across the Mediterranean and beyond.
Context
Jewish communities had lived on the Iberian Peninsula since Roman times. Under Muslim rule in al-Andalus, they held protected dhimmi status that permitted trade, scholarship, and court service, fostering a period of cultural and intellectual achievement known as the Golden Age of Jewish culture in Spain. Christian advances during the Reconquista gradually eroded this tolerance; by the fourteenth century, anti-Jewish violence intensified, most notably in the 1391 massacres and forced conversions that created a large population of conversos, or New Christians.
What Happened
The marriage of Ferdinand and Isabella in 1469 united the crowns of Aragon and Castile, enabling coordinated policies that culminated in the fall of Granada in January 1492 and the completion of the Reconquista. With Muslim rule ended, the monarchs turned to enforcing religious uniformity. The Spanish Inquisition, established in 1478, had already investigated conversos suspected of secretly practicing Judaism. Grand Inquisitor Tomás de Torquemada pressed the rulers to remove any remaining Jewish influence that might encourage crypto-Judaism.
Aftermath
On March 31, 1492, the monarchs signed the edict at the Alhambra palace in Granada. It required all unconverted Jews to leave Castile and Aragon by July 31 or face execution and property confiscation. Jews could take movable goods but were barred from exporting gold, silver, or coined money, forcing many to sell assets at low prices before departure.
Legacy
Between 40,000 and 100,000 Jews chose exile while others converted to remain. The sudden outflow disrupted commerce and finance in which Jewish merchants and moneylenders had played key roles. Exiles dispersed across the Mediterranean, with many welcomed by the Ottoman Empire; their descendants became the Sephardic communities that preserved Ladino language and customs for centuries.
Why It Matters
The decree abruptly ended centuries of Jewish life and scholarship in Iberia, causing economic disruption in trade and finance while fueling the Sephardic diaspora that enriched communities in the Ottoman Empire, North Africa, and the Netherlands. It set a precedent for large-scale religious expulsions in Europe and influenced later policies of exclusion. In modern times, Spain offered citizenship pathways to descendants as partial redress for the historical injustice.
