Explanation:

As the United States had expanded westward, navigation of the Mississippi River and access to the port of New Orleans had become critical to American commerce.

So, in 1803, the then US President, Thomas Jefferson and the government struck a deal with Napoleon Bonaparte, the French Emperor to purchase the 827,000 square mile territory for $15 million. Napoleon needed the money to Finance the french war, and the purchase nearly doubled the size of the young US nation and gave them access to the port in New Orleans as well.

Jefferson's vision for the United States always centered around westward expansion, so the Louisiana Purchase was a considerable boon. through that, they could now expand towards the west towards the rocky mountains.
