United States

But a strong reaction in the United States against acquisition of the Philippines had already set in by the time the Treaty of Paris was signed on December 10, 1898, and anti-imperialists declared that the control and governance of distant alien peoples violated all American traditions of self-determination and would even threaten the very fabric of the republic. Though there were more than enough votes in the Senate to defeat the treaty, that body gave its consent to ratification largely because William Jennings Bryan, the Democratic leader, wanted Democrats to approve the treaty and then make imperialism the chief issue of the 1900 presidential campaign.

The new American empire

McKinley easily defeated Bryan in 1900. The victory, however, was hardly a mandate for imperialism, and, as events were soon to disclose, the American people were perhaps the most reluctant imperialists in history. No sooner had they acquired an overseas empire than they set in motion the process of its dissolution or transformation.

By the so-called Teller Amendment to the war resolution, Congress had declared that the United States would not annex Cuba. This pledge was kept, although Cuba was forced in 1903 to sign a treaty making it virtually a protectorate of the United States. The Hawaiian Islands, annexed by Congress on July 7, 1898, were made a territory in 1900 and were hence, technically, only briefly part of the American empire. Puerto Rico was given limited self-government in 1900, and the Jones Act of 1917 conferred full territorial status on the island, gave U.S. citizenship to its inhabitants, and limited its self-government only by the veto of a governor appointed by the president of the United States. Establishing any kind of government in the Philippines was much more difficult because a large band of Filipinos resisted American rule as bravely as they had fought the Spanish. The Philippine insurrection was over by 1901, however, and the Philippine Government Act of 1902 inaugurated the beginning of partial self-government, which was transformed into almost complete home rule by the Jones Act of 1916.

The Open Door in the Far East

Although Americans were reluctant imperialists, the United States was an important Pacific power after 1898, and American businessmen had inflated ambitions to tap what they thought was the huge Chinese market. The doors to that market were being rapidly closed in the 1890s, however, as Britain, France, Russia, and Japan carved out large so-called spheres of influence all the way from Manchuria to southern China. With Britain’s support (the British stood to gain the most from equal trade opportunities), on September 6, 1899, Secretary of State Hay addressed the first so-called Open Door note to the powers with interests in China; it asked them to accord equal trade and investment opportunities to all nationals in their spheres of interest and leased territories. With considerable bravado, Hay announced that all the powers had agreed to respect the Open Door, even though the Russians had declined to give any pledges. On July 3, 1900, after the Boxer Rebellion—an uprising in China against foreign influence—Hay circulated a second Open Door note announcing that it was American policy to preserve Chinese territorial and political integrity.

Such pronouncements had little effect because the United States was not prepared to support the Open Door policy with force; successive administrations to the 1940s, however, considered it the cornerstone of their Far Eastern policy. Pres. Theodore Roosevelt reluctantly mediated the Russo-Japanese War in 1905 in part to protect the Open Door as well as to maintain a balance of power in the Far East. When Japan attempted in 1915 to force a virtual protectorate on China, Pres. Woodrow Wilson intervened sternly and in some measure successfully to protect Chinese independence. Victory for American policy seemed to come with the Nine-Power Treaty of Washington of 1922, when all nations with interests in China promised to respect the Open Door.
