Final answer:
The War of 1812 resulted in a surge of American national pride and significant economic changes leading to the market revolution. The Treaty of Ghent ended the war without territorial changes but stimulated American manufacturing and infrastructure improvements.
Step-by-step explanation:
Two significant results from the War of 1812 are the surge of national pride in the United States and important changes in the nation's economic infrastructure. The war, sometimes referred to as the "Second War of Independence," ended with the boundaries of the United States remaining unchanged due to the Treaty of Ghent. However, it led to a boost in American identity, exemplified by cultural expressions like the 'Star-Spangled Banner', written by Francis Scott Key during the conflict.
Additionally, the war created economic and social transformations that contributed to the market revolution. The lack of imports during the war stimulated the domestic manufacturing industry, leading to an increase in factory production. The development of interchangeable parts and integrated mills advanced this revolution, which began to more distinctly define the economic differences between the industrial North and the agricultural South.
