. Although he felt that the US Constitution did not contain any provisions for acquiring territory, Jefferson decided to purchase Louisiana because he felt uneasy about France and Spain having the power to block American trade access to the port of New Orleans.

Napoleon Bonaparte, upon completion of the agreement, stated, "This accession of territory affirms forever the power of the United States, and I have given England a maritime rival who sooner or later will humble her pride."

Background

The city of New Orleans controlled the Mississippi River through its location; other locations for ports had been tried and had not succeeded. New Orleans was already important for shipping agricultural goods to and from the parts of the United States west of the Appalachian Mountains

 signed with Spain on October 27, 1795, American merchants had "right of deposit" in New Orleans, meaning they could use the port to store goods for export. Americans also used this right to transport products such as flour, tobacco, pork, bacon, lard, feathers, cider, butter, and cheese. The treaty also recognized American rights to navigate the entire Mississippi River which had become increasingly vital to the growing trade of their western territories. In 1798 Spain revoked this treaty, which greatly upset Americans. In 1801, Spanish Governor Don Juan Manuel De Salcedo took over for Governor Marquess of Casa Calvo, and the right to deposit goods from the United States was fully restored. Napoleon Bonaparte

 began to help negotiate with France at the request of Jefferson. Du Pont was living in the United States at the time and had close ties to Jefferson, as well as to the political powers in France. He engaged in back-channel diplomacy with Napoleon, on Jefferson's behalf, during a personal visit to France. He originated the idea of the much larger Louisiana Purchase as a way to defuse potential conflict between the United States and Napoleon over North America.

Throughout this time, Jefferson had up-to-date intelligence on Napoleon's military activities and intentions in North America. Part of his evolving strategy involved giving du Pont some information that was withheld from Livingston. He also gave intentionally conflicting instructions to the two. He next sent Monroe to Paris in 1803. Monroe had been formally expelled from France on his last diplomatic mission, and the choice to send him again conveyed a sense of seriousness.
