Manila hemp in the context of "Manila galleon"

The Manila galleon (Spanish: Galeón de Manila; Tagalog: Galeon ng Maynila) are the Spanish trading ships that linked the Philippines in the Spanish East Indies to Mexico (New Spain), across the Pacific Ocean. The ships made one or two round-trip voyages per year between the ports of Manila and Acapulco from the late 16th to early 19th century. The term "Manila galleon" can also mean the trade route itself between Manila and Acapulco that was operational from 1565 to 1815.

The Manila galleon trade route was inaugurated in 1565 after the Augustinian friar and navigator Andrés de Urdaneta pioneered the tornaviaje or return route from the Philippines to Mexico. Urdaneta and Alonso de Arellano made the first successful round trips that year, by taking advantage of the Kuroshio Current. The galleons set sail from Cavite, in Manila Bay, at the end of June or the first week of July, sailing through the northern Pacific and reaching Acapulco in March to April of the next calendar year. The return route from Acapulco passes through lower latitudes closer to the equator, stopping over in the Marianas, then sailing onwards through the San Bernardino Strait off Cape Espiritu Santo in Samar and then to Manila Bay and anchoring again off Cavite by June or July. The trade using "Urdaneta's route" lasted until 1815, when the Mexican War of Independence broke out. The majority of these galleons were built and loaded in shipyards in Cavite, utilizing native hardwoods like the Philippine teak, with sails produced in Ilocos, and with the rigging and cordage made from salt-resistant Manila hemp. The vast majority of the galleon's crew consisted of Filipino natives; many of whom were farmers, street children, or vagrants press-ganged into service as sailors. The officers and other skilled crew were usually Spaniards (a high percentage of whom were of Basque descent). The galleons were state vessels and thus the cost of their construction and upkeep was borne by the Spanish Crown.
