What does the Louisiana purchase suggest about the manifest destiny

The purchase was important to the presidency of Thomas Jefferson, who faced some internal resistance to the purchase. Although there were doubts about the constitutionality of the acquisition of the territory, he decided to buy Louisiana because he did not like the idea that France and Spain had the power to block the access of US merchants to the port of New Orleans. This negotiation opened the access to the Pacific Ocean to the United States and dramatically increased its territory, making it one of the historical events with the greatest consequences in the history of the last two centuries of the States.

Since during the Louisiana Purchase, we purchased so much land (technically the whole entire United States). Manifest destiny is our belief to spread from sea to shining sea so, we were motivated to expand to that new land we purchased. That would make the thirteen colonies less crowded and over populated.
