Answer:
The Louisiana Purchase was a land acquisition made by the United States in 1803, in which the U.S. purchased the territory of Louisiana from France. The treaty that facilitated the Louisiana Purchase was signed on April 30, 1803, and was ratified by the United States Senate on October 20, 1803. It was not revoked at any point.
The Louisiana Purchase more than doubled the size of the United States and greatly expanded the country's western border. The purchase included all of the territory west of the Mississippi River, which included parts of modern-day Arkansas, Missouri, Iowa, Oklahoma, Kansas, Nebraska, North Dakota, South Dakota, Wyoming, Colorado, Montana, and parts of Minnesota. It also included the city of New Orleans and other parts of the state of Louisiana. The Louisiana Purchase was a significant event in American history and played a major role in shaping the country's territorial expansion.
