Foreign and domestic policy in the United States in the 19th century?

US foreign policy in the 19th was as follows:

Aggravation of relations with England. As a result, this led to a war between states.
Taking advantage of this war, the United States sought to seize Canada.
Wanting to help Napoleon with money, Louisiana was bought by the US state.
