Manila galleons in the context of "Augustinians"

Guam (/ˈɡwɑːm/ GWAHM; Chamorro: Guåhan [ˈɡʷɑhɑn]) is an island that is an organized, unincorporated territory of the United States in the Micronesia subregion of the western Pacific Ocean. Guam's capital is Hagåtña, and the most populous village is Dededo. It is the westernmost point and territory of the United States, as measured from the geographic center of the U.S. In Oceania, Guam is the largest and southernmost of the Mariana Islands and the largest island in Micronesia. In 2022, its population was 168,801. Chamorros are its largest ethnic group, but a minority on the multiethnic island. The territory spans 210 square miles (540 km; 130,000 acres) and has a population density of 775 per square mile (299/km).

Indigenous Guamanians are the Chamorro, who are related to the Austronesian peoples of the Malay Archipelago, the Philippines, Taiwan, and Polynesia. Unlike most of its neighbors, the Chamorro language is not classified as a Micronesian or Polynesian language. Like Palauan, it possibly constitutes an independent branch of the Malayo-Polynesian language family. The Chamorro people settled Guam and the Mariana islands approximately 3,500 years ago. Portuguese explorer Ferdinand Magellan, while in the service of Spain, was the first European to visit and claim the island in March 1521. Guam was fully colonized by Spain in 1668. Between the 17th and 19th centuries, Guam was an important stopover for Spanish Manila galleons. During the Spanish–American War, the United States captured Guam in June 1898. Under the 1898 Treaty of Paris, Spain ceded Guam to the U.S. effective April 11, 1899.

Chinese Filipinos (sometimes referred as Filipino Chinese or Chinoy/Tsinoy in the Philippines) are Filipinos of full or partial Chinese descent, but are typically born and raised in the Philippines. Chinese Filipinos are one of the largest overseas Chinese communities in Southeast Asia. A large proportion of Chinese Filipinos can trace their ancestry back to the Chinese province of Fujian.

Chinese immigration to the Philippines occurred mostly during the Spanish colonization of the islands between the 16th and 19th centuries, attracted by the lucrative trade of the Manila galleons. During this era, they were referred to as Sangley. They were mostly the Hokkien-speaking Hokkien people that later became the dominant group within the Filipino-Chinese community. In the 19th century, migration was triggered by the corrupt and bad governance of the late Qing dynasty, combined with economic problems in China due to the Western and Japanese colonial wars and Opium Wars. It subsequently continued during the 20th century, from American colonial times, through the post-independence era to Cold War, to the present. In 2013, according to older records held by the Senate of the Philippines, there were approximately 1.35 million ethnic (or pure) Chinese within the Philippine population, while Filipinos with any Chinese descent comprised 22.8 million of the population. However, the actual current figures are not known since the Philippine census does not usually take into account questions about ethnicity. Accordingly, the oldest Chinatown in the world is located in Binondo, Manila, founded on December 8, 1594.

The Spanish treasure fleet, or West Indies Fleet (Spanish: Flota de Indias, also called silver fleet or plate fleet; from the Spanish: plata meaning "silver"), was a convoy system of sea routes organized by the Spanish Empire from 1566 to 1790, which linked Spain with its territories in the Americas across the Atlantic. The convoys were general purpose cargo fleets used for transporting a wide variety of items, including agricultural goods, lumber, various metal resources such as silver and gold, gems, pearls, spices, sugar, tobacco, silk, and other exotic goods from the overseas territories of the Spanish Empire to the Spanish mainland. Spanish goods such as oil, wine, textiles, books and tools were transported in the opposite direction.

The West Indies fleet was the first permanent transatlantic trade route in history. Similarly, the related Manila galleon trade was the first permanent trade route across the Pacific. The Spanish West and East Indies fleets are considered among the most successful naval operations in history and, from a commercial point of view, they made possible key components of today's global economy.
