In short
On 31 March 1492, Spanish monarchs Ferdinand and Isabella issued the Alhambra Decree, giving Jews four months to convert to Christianity or leave Spain entirely. The expulsion scattered one of Europe's oldest Jewish communities across the Mediterranean and North Africa, reshaping both Spanish society and the diaspora for centuries.
How it unfolded.
The five-minute version
What actually happened.
On 31 March 1492, the Catholic Monarchs of Spain, King Ferdinand II of Aragon and Queen Isabella I of Castile, issued the Alhambra Decree, ordering all unconverted Jews to leave their kingdoms and territories by the end of July that year, unless they converted to Christianity. Motivated by a desire for religious unity following the completion of the Reconquista and amid fears that unconverted Jews were influencing conversos to revert to Judaism, the decree brought to an end more than a millennium of Jewish presence in the Iberian Peninsula. It also ranks among the most consequential events in Spanish and Jewish history.

Timeline
How it actually unfolded.
Spanish Inquisition established
The Catholic Monarchs establish the Inquisition under Tomás de Torquemada in 1478 to enforce religious orthodoxy and investigate Jewish converts (conversos) and Muslims.
Granada falls to Christian forces
The Reconquista concludes with Ferdinand and Isabella's conquest of Granada, the last Muslim kingdom in Iberia, consolidating Christian rule and religious momentum.
Alhambra Decree issued
Ferdinand and Isabella sign the Alhambra Decree in Granada, ordering all unconverted Jews to leave Spanish territories by 31 July 1492 or face execution and confiscation of property.
Expulsion deadline
The deadline passes for Jews to either leave Spain or convert. Most depart for Portugal, North Africa, Italy, and the Ottoman Empire; some accept forced conversion.
Columbus expedition sails
Columbus departs from Palos de la Frontera, three days after the Jewish expulsion deadline-a symbolic coincidence of Spain's religious consolidation and imperial expansion.
Portuguese expulsion follows
Portugal's King Manuel I expels or forcibly converts Jews, partly motivated by Ferdinand and Isabella's precedent and pressure from the Spanish monarchy.

What was on the radio, the screen, and everyone's mind.
Same week, elsewhere
1492 marks Columbus's voyage, the completion of the Reconquista, and the establishment of a unified Catholic Spanish state-a year Spain frames as foundational to national identity. The expulsion of Jews, Muslims, and other religious minorities reveals the darker side of that consolidation. The period's cultural production emphasized Christian unity and royal authority; Jewish intellectual and artistic contributions were systematically erased from Spanish memory until modern scholarship began recovery efforts in the 20th century.

Impact
What followed.
Ferdinand and Isabella's 1492 expulsion order forced an estimated 150,000–200,000 Jews from Spain.-one of Europe's largest medieval Jewish communities-in a single year. The decree shaped centuries of diaspora, migration patterns to Ottoman territories and the Americas, and redefined Spain's religious and political identity at the moment Columbus sailed west.
