Isabella Expels Jews: The Alhambra Decree Enforced

Queen Isabella and King Ferdinand gave Spain's Jews four months to convert or leave everything behind. The Alhambra Decree, signed on March 31, 1492, ordered the expulsion of all Jews from Spain who refused baptism, ending more than a thousand years of Jewish presence on the Iberian Peninsula. An estimated 40,000 to 100,000 Jews chose exile, abandoning homes, businesses, and communities that had produced some of the medieval world's greatest philosophers, physicians, and poets. The decree was the culmination of decades of escalating persecution. Spain's Jewish communities had been targets of mass violence since the pogroms of 1391, which destroyed Jewish quarters in cities across Castile and Aragon. Tens of thousands converted to Christianity under duress, becoming "conversos" who remained under suspicion of secretly practicing Judaism. The Spanish Inquisition, established in 1478, was specifically designed to investigate converso sincerity, and its investigations produced a climate of terror that made coexistence impossible. The timing was deliberate. Ferdinand and Isabella signed the decree less than three months after conquering Granada, the last Muslim state on the peninsula. The monarchs who had completed the Reconquista now aimed to create a religiously unified Spain. The Grand Inquisitor, Tomas de Torquemada, was reportedly the decree's most forceful advocate, though Ferdinand's desire to seize Jewish property and debts was equally motivating. The expelled Jews scattered across the Ottoman Empire, North Africa, Italy, and the Netherlands, establishing Sephardic communities that preserved their Ladino language and Iberian traditions for centuries. Istanbul, Thessaloniki, and Amsterdam became new centers of Sephardic culture. Spain's loss was the Ottoman Empire's gain: Sultan Bayezid II reportedly said of Ferdinand, "You call this man wise? He has impoverished his land to enrich mine." Spain did not formally revoke the Alhambra Decree until 1968.
