The primary outcome of the War of 1812 between the United States and Great Britain was the reaffirmation of American independence. Although the war did not significantly change territorial boundaries, it fostered a sense of nationalism and unity among Americans. The conflict highlighted the challenges the young nation faced, including military limitations and trade restrictions, leading to further industrialization. The successful defense of key battles, such as the Battle of New Orleans, bolstered national pride. Additionally, the war's end in 1815 marked the decline of Federalist opposition and ushered in the "Era of Good Feelings," characterized by political stability and economic expansion.
