Which land acquisition doubled the size of the United States?

• A. Texas Annexation
• B. Oregon Territory
• C. Louisiana Purchase
• D. Gadsden Purchase

Answer: (C)

The Louisiana Purchase, completed in 1803, was a monumental land acquisition that effectively doubled the size of the United States at the time. This vast expanse of land, approximately 828,000 square miles, was purchased from France for $15 million. It included territory that would eventually become parts of 15 different states, stretching from the Mississippi River to the Rocky Mountains and securing vital land for westward expansion.

This acquisition was significant not only because of the sheer size but also due to its strategic importance. It provided the United States with control over the Mississippi River, which was essential for trade and transportation. Moreover, the purchase facilitated further westward exploration and settlement, including the Lewis and Clark expedition.

In contrast, the other land acquisitions mentioned did not double the size of the nation. The Texas Annexation brought a substantial amount of land into the United States but did not compare to the scale of the Louisiana Purchase. The Oregon Territory, while significant, involved a negotiated settlement and primarily extended the nation to the Pacific Northwest rather than doubling its land area. The Gadsden Purchase was a relatively small land deal aimed at facilitating the construction of a southern transcontinental railroad.
