Despite such widespread isolationist impulses and the sheer inability to maintain a strong international position, the United States moved ahead sporadically with a modest foreign policy agenda in the three decades following the Civil War. Secretary of State William Seward, who held that position from 1861 through 1869, sought to extend American political and commercial influence in both Asia and Latin America. He pursued these goals through a variety of actions. A treaty with Nicaragua set the early course for the future construction of a canal across Central America. He also pushed through the annexation of the Midway Islands in the Pacific Ocean, which subsequently opened a more stable route to Asian markets. In frequent conversations with President Lincoln, among others, Seward openly spoke of his desire to obtain British Columbia, the Hawaiian Islands, portions of the Dominican Republic, Cuba, and other territories. He explained his motives to a Boston audience in 1867, when he professed his intention to give the United States “control of the world.”
Most notably, in 1867, Seward obtained the Alaskan Territory from Russia for a purchase price of $7.2 million. Fearing future loss of the territory through military conflict, as well as desiring to create challenges for Great Britain (which they had fought in the Crimean War), Russia had happily accepted the American purchase offer. In the United States, several newspaper editors openly questioned the purchase and labeled it “Seward’s Folly” (Figure 22.3). They highlighted the lack of Americans to populate the vast region and lamented the challenges in attempting to govern the native peoples in that territory. Only if gold were to be found, the editors decried, would the secretive purchase be justified. That is exactly what happened. Seward’s purchase added an enormous territory to the country—nearly 600,000 square miles—and also gave the United States access to the rich mineral resources of the region, including the gold that trigged the Klondike Gold Rush at the close of the century. As was the case elsewhere in the American borderlands, Alaska’s industrial development wreaked havoc on the region’s indigenous and Russian cultures.
