Which of the events listed had most affected the early development of the United States? Why do you think so? What were the effects of the event?

The War of 1812
The Louisiana Purchase
The Monroe Doctrine

My      I think the Louisiana purchase influenced the early development of the United States because It has made over five states over the years. But, I also think the Louisiana Purchase led to the war of 1812 since the British limitations on the United States trade and America increasing their sizes to the U.S. This caused the U.S to become incredibly wealthy and left the rest needing money to help pay for things like Soldiers and war supplies. The effects of the event caused up some issues in the constitution, and the leaders deciding rather or not the Louisiana Purchase should continue. As this was all going on, The Monroe Doctrine became a U.s Policy that stated how European powers do not belong in America or the western hemisphere. But, this policy failed because the United States didn't have, nor was a prominent power at the time, and affected their relationship with Latin America.

More on my answer if need or want:  The Louisiana purchase influenced the early development of the United States because It has made over five states over the years. The Louisiana purchase is was one of the most major land purchases we had in all of American history. The U.S paid as high as $15 Million for France. The Louisiana purchase got the states of Louisiana, South Dakota, Arkansas, Iowa, North Dakota, Missouri, Nebraska, and Oklahoma. The reasons for these states were for future protection, expansion, and wealth. But, the Louisiana Purchase led to the war of 1812 since the British limitations on the United States trade and America increasing their sizes to the U.S. This caused the U.S to become incredibly wealthy and left the rest needing money to help pay for Soldiers and war supplies. Not only trade led to the War but Impressment and Native American Involvement. The Impressment involved Britain's Navy transmitting officers to board American vessels and capture mariners accused of being renegades from British ships. The Native Americans wanted to protect their tribal lands, so the U.S can not force the Native Americans to leave. The effects of the event caused up some issues in the constitution, and the leaders deciding rather or not the Louisiana Purchase should continue. As this was all going on, The Monroe Doctrine became a U.S Policy that stated how European powers do not belong in America or the western hemisphere. But, this policy failed because the United States didn't have, nor was a prominent power at the time, and affected their relationship with Latin America. This war ended off on the battlefield. The Treaty of Ghent incandesced that all territories were to be placed back the way it was. The treaty was inscribed by the British and American representatives.
