What happened
On January 2, 1492, the emirate of Granada, the last Muslim territory in Iberia, surrendered to the forces of Ferdinand and Isabella, ending nearly 800 years of Muslim political presence on the peninsula and completing the Reconquista. Two months later, on March 31, the monarchs issued the Alhambra Decree, ordering all Jews in Castile and Aragon to convert to Catholicism or leave the kingdom by the end of July. The decree itself, issued from Granada, stated the crown's reasoning directly: it accused Jews of drawing Christian converts back toward Judaism and declared that banishment was the only remedy left after twelve years of Inquisition proceedings had failed to end the practice. Modern estimates of the number expelled range from roughly 40,000 to as many as 200,000 out of Spain's Jewish population of about 300,000. That same year, Ferdinand and Isabella financed Christopher Columbus's westward voyage, which reached land in the Caribbean that October.
Why it matters
Three events in a single year, the end of a war fought since the 8th century, the expulsion of a community that had lived in Iberia for over a thousand years, and a voyage that opened the Americas to European conquest, made 1492 the hinge on which Spanish and world history turned. The expulsion's death toll is not itself the issue in dispute; what is debated is the total number who left, given imprecise 15th-century records. The fuller stories of the Inquisition and the expulsion are told in the Spanish Empire timeline, and Columbus's voyage in the Age of Exploration timeline.
How we know
The fall of Granada is dated precisely in Spanish and Muslim chronicles of 1492, and the Alhambra Decree survives as a primary legal document issued in the names of Ferdinand and Isabella and signed by their royal secretary, Juan de Coloma, giving a direct textual record of the crown's own stated justification.
