On April 30, 1803, France sold almost 830,000 square miles of territory west of the Missuissippi River to the United States. The price: $15,000,000. The event marked the end of French hopes to establish an empire in North America. Known as the Louisiana Purchase, it also ended a long struggle for access to and politicsl control of the Mississippi River.

As the United States spread across the Appalachians, the river became increasingly important as a conduit for the produce of America’s West which at that time referred to the land between the Appalachians and the Mississippi. Since 1762, Spain had owned the territory of Louisiana, which itoday makes up all or part of fifteen separate states between the Mississippi River and the Rocky Mountains. Friction between Spain and the United States over the right to navigate the Mississippi and the right for Americans to transfer their goods to ocean-going vessels at New Orleans had been resolved by the Pinckney Treaty of 1795. With the Pinckney Treaty in place and the weak Spanish empire in control of Louisiana, American statesmen felt comfortable that the United States’ westward expansion would not be restricted in the long run.
There is on the globe one single spot, the possessor of which is our natural and habitual enemy. It is New Orleans.
