A detailed logbook created during the difficult Loaísa expedition served as the primary source for understanding the mid-16th-century Pacific spice trade. Authored by a Basque navigator who spent over eight years in the Spice Islands, this narrative provided crucial geographic data to the Crown of Castile and helped finalize the routes for future trans-Pacific voyages.
Early Maritime Service
Born in 1508 near Ordizia, Urdaneta came from a prominent local family. At age 17, he secured a position as a page to Juan Sebastián Elcano during the Loaísa expedition, an imperial mission tasked with establishing a trade presence in the East Indies. The voyage faced immense hardships; by the time the Santa Maria de la Victoria reached the Spice Islands in 1526, scurvy and storms had decimated the fleet. Urdaneta remained in the region for nearly a decade, managing reconnaissance missions and acting as an emissary until the 1534 repatriation agreement allowed his return to Europe.

Upon reaching Valladolid in 1537, Urdaneta provided the Council of the Indies with an extensive report on his experiences. He subsequently moved to the New World in 1538 to serve as chief navigator for Pedro de Alvarado. Following Alvarado’s death during a suppression of a native rebellion in New Galicia, Urdaneta settled into administrative roles under Viceroy Antonio de Mendoza. He served as a corregidor in Michoacán and as a visitador, tasked with auditing local officials and addressing the treatment of native populations.
Charting the Pacific Return
In 1552, Urdaneta became an Augustinian friar, yet he retained his interest in maritime navigation. At the request of Philip II, he joined the Legazpi expedition to the Philippines. During this mission in 1565, he successfully discovered and plotted an easterly passage from the Philippines to Acapulco. This path, known as the Manila galleon route, provided a practical solution for trade and colonization across the Pacific for over two centuries. He spent his final years in Mexico City, where he passed away in 1568.
