In 1802, Spain closed American access to the ports in New Orleans. In order to resolve this issue, Thomas Jefferson asked James Monroe to travel to France to help the U.S envoy, Robert Livingston, purchase as much land to west as they could for $10,000,000. Upon Monroe’s arrival in France, he learned that Talleyrand had offered to sell Livingston the entirety of the Louisiana Territory. France had been trying to “pull out” of America after the Haitian Revolution in the 1790’s, so this was seen as a good opportunity for them to do so. Monroe and Livingston entered negotiations right away, and eventually agreed upon buying the entire 827,000 square mile territory for $15,000,000, which succeeded the amount authorized. When Jefferson got word from Monroe of the deal, Jefferson immediately said that the purchase was unconstitutional(he did believe in a strict interpretation of the document after all). Jefferson eventually ceded and purchased the land for the agreed amount, averaging out to less than 3 cents per acre. This purchase ended up doubling the area of the United States and eventually added 13 more states to the country.
