How did America finance the Louisiana purchase?
It cost them 15 million dollars so they did it with the taxes that were being paid by citizens of the u.s.
The Louisiana Purchase was one of the greatest land deals ever to take place. Louisiana was so big that it made our nation over 23% bigger, making America difficult to attack. It also gave the American colonies a place to legally expand to. Before we purchased it from France, Americans were illegally moving there anyway. To sum it all up, the Louisiana Purchase was a prerequisite to the growth and the sustaining of America.
