Supported by the Spanish monarchs, Columbus reached the Bahamas on October 12, 1492, an event that initiated permanent contact between Europe and the Americas and led to Spanish colonial expansion. However, recent historical claims have challenged this traditional account. José Guerrero Sánchez, director of the National Museum of History and Geography, proposes that navigator Martín Alonso Pinzón Yáñez was the true discoverer. Guerrero argues that Pinzón reached continental lands a day earlier, on October 12, 1492, aboard the ship La Pinta. Guerrero cites the absence of the October 12 date in Columbus’s own travel diary as evidence that Columbus may have omitted the date to conceal Pinzón’s earlier arrival. Additionally, the research suggests a rift between the explorers occurred because Columbus allegedly failed to honor the Capitulaciones de Santa Fe agreement, which had promised Pinzón specific titles and payments. ## Timeline ### 2026-10-11: Christopher Columbus reaches the Americas On October 12, 1492, Christopher Columbus reached the Bahamas, initiating permanent contact between Europe and the Americas and beginning the era of Spanish colonial expansion. 2 sources. https://clstr.news/cluster/christopher-columbus-reaches-the-americas ### 2026-09-21: Historian claims Martín Alonso Pinzón Yáñez discovered America Historian José Guerrero Sánchez argues that Martín Alonso Pinzón Yáñez was the first to reach the Americas on October 12, 1492, citing gaps in Christopher Columbus’s travel diary. 2 sources. https://clstr.news/cluster/historian-claims-martn-alonso-pinzn-yez-discovered-america --- Cite as: Historical debate over the discovery of America.
