Answer:
One way that the United States was affected by the outcome of the War of 1812 was that it helped to establish the country's national identity and unity.
Step-by-step explanation:
Prior to the war, the United States was still a young and relatively weak nation, and it faced many challenges to its sovereignty and independence. The successful defense against British invasion and the negotiation of a favorable peace treaty helped to solidify the United States' position on the world stage and to boost national morale and confidence. The war also had a number of other important consequences, including the expansion of American territory and the growth of American industry and trade.
