49 Patterns of American Interventions
American interventions in the Mexico, China, and the Middle East reflected a new eagerness of the United States to intervene in foreign governments to protect American economic interests abroad.
The United States had long been involved in Pacific commerce. American ships had been travelling to China, for instance, since 1784. As a percentage of total American foreign trade, the Asian trade remained comparatively small, and yet the idea that Asian markets were vital to American commerce affected American policy and, when those markets were threatened, prompted interventions. In 1899, Secretary of State John Hay articulated the “Open Door Policy,” which called for all western powers to have equal access to Chinese markets. Hay feared that other imperial powers—Japan, Great Britain, Germany, France, Italy, and Russia—planned to carve China into spheres of influence. It was in the economic interest of American business to maintain China for free trade. The following year, in 1900, American troops intervened to prevent the closing of trade. American troops helped to put down the Boxer Rebellion, a movement opposed to foreign businesses and missionaries operating in China. President McKinley sent the U.S. Army into China without consulting Congress, setting a precedent for U.S. presidents to order American troops to action around the world under their executive powers.
The United States was not only ready to intervene in foreign affairs to preserve foreign markets, it was willing to take territory. The United States acquired its first Pacific territories with the Guano Islands Act of 1856. Guano—collected bird excrement—was a popular fertilizer integral to industrial farming. The Act authorized and encouraged Americans to venture into the seas and claim islands with guano deposits for the United States. These acquisitions were the first insular, unincorporated territories of the United States: they were neither part of a state nor a federal district, and they were not on the path to ever attain such a status. The Act, though little known, offered a precedent for future American acquisitions.
Merchants, of course, weren’t the only American travelers in the Pacific. Christian missionaries soon followed explorers and traders. The first American missionaries arrived in Hawai’i in 1820 and China in 1830, for instance. Missionaries, though, often worked alongside business interests, and American missionaries in Hawai’I, for instance, obtained large tracts of land and started lucrative sugar plantations. During the nineteenth century, Hawai’i was ruled by an oligarchy based on the sugar companies, together known as the “Big Five.” This white American “haole” elite was extremely powerful, but they still operated outside for the formal expression of American state power.
As many Americans looked for empire across the Pacific, others looked to Latin America. The United States, long a participant an increasingly complex netwo
