The treaty signed between the United States and the Kingdom of Hawaii in 1887 marked a significant shift in geopolitics in the Pacific. As the U.S. sought to expand its naval presence in the region, the strategic location of Pearl Harbor became increasingly attractive. Negotiated by John L. Stevens, the U.S. Minister to Hawaii, and King Kalākaua, the agreement allowed for the establishment of a coaling station and naval base at Pearl Harbor, which provided the U.S. military with essential logistics for operations in the Pacific. The treaty reflected American expansionist ambitions during the period known as 'Manifest Destiny', where there was a push to acquire territories beyond the continental United States.The context of this event can be traced back to the increasing economic and political interests of the United States in the Hawaiian Islands. The sugar industry in Hawaii was particularly attractive to American investors, leading to growing American influence over local politics and economics. The treaty was not only about military strategy but also underscored broader economic interests that intertwined with America’s imperial ambitions. As a result, the U.S. gained control over one of the most important strategic locations in the Pacific, shaping future military and economic policies in the region.Furthermore, the acquisition of Pearl Harbor set the stage for the eventual annexation of Hawaii in 1898 and the establishment of a U.S. territory. This expansion was met with both support and resistance, laying the groundwork for ongoing discussions about sovereignty, governance, and the rights of native inhabitants. The treaty also highlighted the evolving nature of U.S. foreign policy, shifting from a focus on continental expansion to international influence, ultimately positioning the United States as a significant power in the Pacific.
