What territory did the United States acquire from France in 1803?

The territory acquired by the United States from France in 1803 is known as the Louisiana Territory. This purchase was significant because it doubled the size of the United States at the time, providing vast tracts of land for exploration and settlement. The Louisiana Purchase was finalized on April 30, 1803, and officially ratified in the Senate in October of that year. It included land that would eventually become parts of 15 different states, stretching from the Gulf of Mexico up to Canada and from the Mississippi River to the Rocky Mountains.

The acquisition played a crucial role in furthering westward expansion and was instrumental in promoting agriculture and settlement across the new American frontier. The deal also had important implications for U.S. relations with indigenous peoples and other nations in North America.

The other options, although they represent territories that became associated with the United States, were not acquired through the Louisiana Purchase. Florida was acquired through negotiations with Spain, California became part of the United States after the Mexican-American War, and Texas was an independent republic before joining the union.
