Conclusion

On October 20, 1803, Congress ratified the Louisiana Purchase. France formally transferred Louisiana to the United States in December.

The Louisiana Purchase ended the right of self purchase and excluded free people of color from participating in Democratic Institutions. The city of New Orleans restricted the activities of free people of color, limiting their movement from one location to another, requiring them to carry freedom papers, and to seek consent from the mayor to reside within the city. A new law required all free slaves to leave the state within thirty days while owners were forced to post a $1,000 bond to ensure departure.

The Louisiana Purchase displaced Native Americans. As the country grew, they were forced off their land. Many dying along the road, they were subjected to unjust treaties, genocide, and discrimination.

"If we had not made this purchase, it would have pinched off the possibility of our becoming a continental power. That, in turn, would have meant our ideas on freedom and democracy would have carried less weight with the rest of the world. This was the key to our international influence."
~ Stepehen E. Ambrose, The Mississippi and the Making of a Nation

With careful diplomacy, the United States successfully negotiated with France to buy the Louisiana Territory. Even though there was no constitutional authority to do so, the Louisiana Purchase changed the country, not only doubling the size but also transforming the population. Many European citizens who became Americans with a dip of a pen managed to keep their cultural uniqueness and traditions. Louisiana boundaries reshaped themselves as more states joined the Union. Native Americans and free people of color were forced to leave their lands. The Port of New Orleans became the biggest slave market in the country.
