What changed the fate not only of Hawaii but of the United States and, indeed, the world? The Spanish-American War. Before our 1898 intervention in the Cuban war for independence from Spain, we were a republic. After the Treaty of Paris, which ended the war and brought some Spanish territories under US control, we were an empire. Before, we were a single people whose values and institutions were applicable mainly to ourselves. After, we were a collection of diverse unwilling peoples on whose histories and aspirations those values and institutions would have to be imposed. In addition to Hawaii, the Philippines, Puerto Rico and Guam were now also “ours.”
