The Expansion of the United States: Key Events and the Alaska Purchase

Overview of U.S. Territorial Expansion

Throughout its history, the United States has transformed from 13 colonies into a vast nation through significant territorial expansions. For a deeper understanding of the early stages of this transformation, check out A Comprehensive Review of Unit 2: AP US History (1607-1754).

Key Events in U.S. Expansion

  • Louisiana Purchase (1803): Doubled the size of the U.S. overnight.
  • Mexican-American War (1840s): Led to the annexation of Texas and acquisition of California, Arizona, New Mexico, and parts of Colorado, Utah, and Nevada. To learn more about the development of these territories, see Understanding the Development of British Colonies in North America.
  • Acquisitions: Included Florida, Alaska, and the Oregon Territory, with the Gadsden Purchase in 1853 adding more territory in the southwest.
  • Post-Civil War Growth: Rapid westward expansion as settlers claimed land, officially closing the Western frontier by 1890. For insights into life during this period, refer to Understanding Life in the American West: Opportunities and Challenges.
  • Spanish-American War (1898): Resulted in the acquisition of Puerto Rico, Guam, and the Philippines.

The Alaska Purchase

  • Early Russian Presence: Russian merchants arrived in Alaska in 1732, with the Russian-American Company chartered in 1799.
  • Russian Sovereignty: In 1821, Russia claimed sovereignty over the North American Pacific Coast, leading to the Russo-American Treaty of 1824.
  • Decline of the Fur Trade: By the 1850s, the sea otter population had dwindled, prompting Russia to consider selling Alaska.
  • Negotiations: Began in 1859 but were interrupted by the Civil War; resumed in 1867 under Secretary of State William Seward.
  • Purchase Agreement: The U.S. acquired Alaska for $7.2 million, approximately 2 cents per acre, with the Senate approving the treaty on April 9, 1867. This acquisition is part of a broader narrative of American expansion, which is explored in Exploring America's Colonial History: The British Atlantic World (1660-1750).
  • Initial Skepticism: The purchase was criticized as a waste, dubbed "Seward's Folly."

Impact of the Alaska Purchase

  • Economic Development: Initially slow, but the seal fishery became profitable, and the Klondike Gold Rush in 1896 spurred population growth and commerce.
  • Geopolitical Consequences: For Russia, it marked a decline in influence in North America; for the U.S., it secured valuable resources and strategic military locations.
  • Long-term Value: Alaska's resources contributed to U.S. economic growth and played a crucial role in World War II, solidifying America's global power status.

Conclusion

Today, Alaska is the largest U.S. state, known for its natural beauty and resources, continuing to attract visitors and businesses.
