of law throughout the length and breadth of the land, in establishing the pax Americana." With the rise of the New Imperialism in the Western hemisphere at the end of the 19th century, debates arose between imperialist and isolationist factions in the U.S. Here, Pax Americana was used to connote the peace across the United States and, more widely, as a Pan-American peace under the aegis of the Monroe Doctrine. Those who favored traditional policies of avoiding foreign entanglements included labor leader Samuel Gompers and steel tycoon Andrew Carnegie. American politicians such as Henry Cabot Lodge, William McKinley, and Theodore Roosevelt advocated an aggressive foreign policy, but the administration of President Grover Cleveland was unwilling to pursue such actions. On January 16, 1893, U.S. diplomatic and military personnel conspired with a small group of individuals to overthrow the constitutional government of the Kingdom of Hawaii and establish a Provisional Government and then a republic. On February 15, they presented a treaty for annexation of the Hawaiian Islands to the U.S. Senate, but opposition to annexation stalled its passage. The United States finally opted to annex Hawaii by way of the Newlands Resolution in July 1898. After its victory in the Spanish–American War of 1898 and the subsequent acquisition of Cuba, Puerto Rico, the Philippines, and Guam, the United States had gained a colonial empire. By ejecting Spain from the Americas, the United States shifted its position to an uncontested regional power, and extended its influence into Southeast Asia and Oceania. Although U.S. capital investments within the Philippines and Puerto Rico were relatively small, these colonies were strategic outposts for expanding trade with Latin America and Asia, particularly China. In the Caribbean area, the United States established a sphere of influence in line with the Monroe Doctrine, not explicitly defined as such, but recognized in effect by other governments and accepted by at least some of the republics in that area. The events around the start of the 20th century demonstrated that the United States undertook an obligation, usual in such cases, of imposing a "Pax Americana". As in similar instances elsewhere, this Pax Americana was not quite clearly marked in its geographical limit, nor was it guided by any theoretical consistency, but rather by the merits of the case and the test of immediate expediency in each instance. Thus, whereas the United States enforced a peace in much of the
