Balboa Sights the Pacific

Vasco Nunez de Balboa was a Spanish conquistador and a leader of the early colony at Darien on the Isthmus of Panama. Drawn by reports from indigenous peoples of a great sea and rich lands lying beyond the mountains, he organized an expedition across the rugged, jungle-covered isthmus in 1513, accompanied by a band of Spaniards and hundreds of native guides and porters.

After a difficult march through dense forest and hostile territory, Balboa climbed a ridge and on September 25, 1513, became the first European known to sight the eastern shore of the Pacific Ocean from the New World. A few days later he reached the water's edge and, wading in with his sword and banner, formally claimed the ocean and all its shores for the Spanish crown, naming it the South Sea.

Balboa's discovery proved that another vast ocean lay between the Americas and Asia, intensifying the European search for a sea passage through or around the continent. It helped inspire Ferdinand Magellan's later voyage, which found a route to the Pacific. Balboa himself fell victim to colonial rivalries and was executed in 1519 on charges brought by a rival governor, despite his pivotal achievement.
