The Louisiana Purchase gave the U.S. control of the Mississippi River and the port city of New Orleans, both of which were used by farmers to ship their crops and get paid. It also ensured that France and probably other European countries would not try to take the land.
The purchased territory included the whole of today's Arkansas, Iowa, Missouri, Kansas, Oklahoma, and Nebraska, parts of Minnesota and Louisiana west of Mississippi River, including New Orleans, big parts of North and northeastern New Mexico, South Dakota, northern Texas, some parts of Wyoming, Montana, and Colorado.
The Louisiana Purchase had several impacts on the United States. The first impact is that it doubled the size of the country. Our borders went from the Atlantic Ocean to the Rocky Mountains, north to Canada, and south to the boundary with Spanish Florida. ... This helped western farmers remain loyal to our country.
In exchange, the United States acquired the vast domain of Louisiana Territory, some 828,000 square miles of land. The treaty was dated April 30 and signed on May 2. In October, the U.S. Senate ratified the purchase, and in December 1803 France transferred authority over the region to the United States.
