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

The United States acquired the Louisiana Territory from France in 1803 through a significant event known as the Louisiana Purchase. This acquisition doubled the size of the United States at the time, adding approximately 828,000 square miles of territory. The deal not only provided land for future expansion but also secured control of the Mississippi River, which was vital for trade and transportation. The Louisiana Purchase was a landmark moment in American history, as it opened up vast areas for exploration and settlement.

The Florida Territory, the Oregon Territory, and the Texas Territory were not part of this transaction. Each of these territories was acquired through different means and at later dates, making the Louisiana Purchase a singularly important event in U.S. territorial expansion.
