galeón de Manila ruta del Pacífico
The maritime line that linked New Spain with the Philippine Islands between 1565 and 1815 represents one of the longest and most productive chapters of transoceanic navigation. For two hundred and fifty years, the Manila galleon—also called the Acapulco ship—crossed the Pacific in both directions, transporting American silver to Asia and silks, porcelain, and spices to the West. The route was based on a decisive nautical discovery: the return journey, the return route from the Philippines that avoided the trade winds of the North Pacific.
The relevance of this corridor was not only commercial. The galleon trade ensured the maintenance of the islands as a Spanish colony through the benefits of the distribution of Asian products in America. Without that regular connection, the Philippine archipelago would hardly have maintained its status as a territory of the Hispanic Monarchy for three centuries.
Urdaneta’s return trip: the gateway to the Pacific
The problem with transpacific navigation was not the way out—the trade winds pushed the ships from Acapulco toward the west—but the return. For years, returning along the same route was unfeasible due to contrary winds. The solution came in 1565 from the hand of Andrés de Urdaneta.
Cebu’s defeat at Acapulco
On June 1, 1565, Urdaneta began his return trip to Acapulco across the Pacific in Manila. He sailed north in search of a favorable current that allowed him to reach his destination on October 8, 1565. The discovery of this route, the tornaviaje, led to the establishment of one of the longest and most important regular maritime lines in history. The inaugural voyage departed from Cebu under the command of Felipe de Salcedo, with pilots Esteban Rodríguez and Rodrigo from Isla Espinosa, while Urdaneta supervised the defeat. After traveling 1,650 leagues in 129 voyages, they anchored in Acapulco at dawn on October 8.
The maneuver consisted of ascending to latitudes close to forty degrees north, where the westerly winds – the so-called «general winds» – propelled the ship towards the coast of California. From there we descended to the port of Acapulco. The route was so effective that it remained practically unchanged throughout the galleon’s history.
The Legazpi expedition and the role of Urdaneta
The expedition that made this feat possible left on November 21, 1564 from New Spain. Two galleons and two pataches under the command of Miguel López de Legazpi, with Urdaneta as chief pilot, set sail with instructions to settle in the western islands. During the voyage they anchored in the Marshall Islands – baptized as “the Barbudos” – and then in the Ladrones, the name by which the Marianas were then known.
Urdaneta was not an inexperienced sailor. He had embarked at the age of seventeen as a page and assistant to Elcano on the Loaysa expedition, the first Castilian attempt to reach the Moluccas after the return of Magellan. That early experience in western Pacific waters gave him direct knowledge of the region’s winds and currents.
Shipbuilding and shipyard operation
The demand for ships for the Acapulco line generated a shipbuilding system with its own characteristics. There were two ways to obtain ships: direct construction in the port of Cavite, taking advantage of the wood from the islands, and the acquisition in Asian markets of ships with all their supplies, due to the higher quality and more attractive prices they offered.
The Cavite shipyard: wood, poles and revolts
The Cavite shipyard became the archipelago’s main galleon building center. The galleons San Sabiniano, San José and Nuestra Señora de la Victoria were under simultaneous construction when the Pampanga and Bulacan uprising broke out. The main point of this uprising was that the poles—the indigenous workers mobilized by the forced labor system—only wanted to collect back pay.
Shipbuilding, in its demands for wood, was the main incentive for the development of a specific forestry with the technological purpose of obtaining wood of adequate quality, size and shapes. The cutting of wood in the forests of the island of Luzon, destined for Cavite, became a heavy burden for the indigenous communities.
The treatment of polo players and the Perenetic Discourse
The pressure on indigenous workers reached extremes that were denounced by the religious authorities themselves. In 1657, the Manila Perenetic Discourse denounced the inhumanity of the treatment inflicted on the polo players. The indigenous people, to avoid the compliance of the Poles, had slaves of the same nature and nation, dedicated to tilling the land or building boats. They were the sanguiguicos, «little blacks» captured by the Malays, who performed domestic and forced labor and lacked property.
The most notable revolt was that of Pampanga in 1660, which began in the provinces of Pampanga, Pangasinán and Ilocos, to which must be added the demand for timber cutting. Although the native Filipinos had notable expertise in the construction of native vessels—bancas, vintas, caracoas, praos, pangas, and barangayanes—they were completely unaware of the construction of European-style galleons, which forced them to combine forced labor with specialists from New Spain.
Life on board: crew, passengers and cargo
The Manila galleon was not just any ship. The dimensions and loading capacity grew over the years, but life on board remained constant throughout the entire history of the route.
Equipment and vessels
The available figures indicate that Martín de Rentería’s «large» galleon was the ship with the largest crew—192 men—in proportion to its thousand tons of tonnage. The average crew of the ships, however, ranged between forty and fifty crew members. A concrete example: the urca Samson, weighing 804 tons, carried 50 men.
These figures contrast with the passage, which could be considerably higher. In the Tierra Firme fleet of 1586, the 900-ton, 50-meter-long captain transported almost a thousand passengers. The difference between crew and passengers was not minor in terms of management of supplies and water on board.
Bans and scales
Life on board was regulated by strict rules. The presence of women on board was not allowed, except for the daughters and wives of those destined for the Moluccan forts, a case that occurred very infrequently.
The galleon route from Manila to the west included a common stopover: the distance between the ports of Cavite and the Moluccas was about 300 leagues according to sources of the time—one hundred leagues less than the Manila-Malacca route—which made the Moluccas an almost obligatory stopover for supplies. The Jesuits, for their part, took 88 days on the Acapulco-Marianas trip in 1668, between March 23 and June 14.
Shipwrecks and underwater archeology
The regularity of the line was not without losses. Each shipwreck practically cut off the Manila-Acapulco connection, hence the urgent need to build new galleons. The vulnerability of the line was demonstrated repeatedly.
The San Diego and the San Agustín
The galleon San Diego was shipwrecked in the waters of the Philippine archipelago; Part of its remains are currently exhibited in the Naval Museum of Madrid. The shipwreck of the San Agustín, which occurred in 1595, was recounted in detail in the chapter «The Adventure of the San Agustín», which describes the accident and the adventures of the survivors. Both cases have been subject to looting reported by the media, a recurring problem in underwater archeology of the Pacific.
The Concepción and the vulnerability of the line
The galleon Concepción burned in the port of Manila itself, which shows that the danger did not lie solely in storms or enemy attacks during the voyage. The loss of a galleon meant the interruption of trade for at least a year, with the consequent consequences for the economy of the islands.
The galleon trade and its economic context
The economic dimension of the route was decisive. The galleon trade ensured the maintenance of the islands as a Spanish colony through the benefits of the distribution of Asian products in America. The route was known as the «Vuelta del Poniente», and the Philippines-California-Acapulco route was used for more than three centuries as a route into America for oriental products, including spices.
American silver and Asian products
The counterpart to Asian goods was American silver. New Spain’s trade with the Philippines was based on this exchange: silks, porcelain, ivories, lacquered furniture, cotton and spices arrived in Acapulco, while Mexican and Peruvian silver flowed to China and other Asian markets. A good part of the silver was used to purchase products that the Crown itself acquired for its own consumption or to supply the islands.
This trade flow was not without controversy. The merchants of New Spain and Peru saw unfair competition in the galleon, and the Spanish Crown alternated periodic attempts at restriction with the need to maintain the islands. The result was an unstable balance that lasted two and a half centuries.
The twilight of the route
The last Manila galleon set sail in March 1815. The independence of New Spain and the Napoleonic Wars had made unsustainable a route that ultimately depended on the political and administrative connection between Mexico and the Philippines. The Vuelta del Poniente, the corridor that had linked both ends of the Pacific for 250 years, was coming to an end.
The route leaves an appreciable material and immaterial. The wrecks of the galleons—the San Diego, the San Agustín and others—are archaeological testimony of a navigation system that sustained communication between two continents. The documentary sources preserved in the General Archive of the Indies and the chronicles of the time allow us to reconstruct the real conditions of a naval company of colossal dimensions.
The Manila Galleon was, above all, the demonstration that regular navigation across the largest ocean on the planet was technically possible with the means of the time. The combination of nautical knowledge, sufficient wood, and organized labor produced a system that operated without interruption for two and a half centuries. Its story is the story of how the Pacific stopped being an obstacle and became a corridor.
