The result of the War of 1812 for the United States was a renewed sense of nationalism and the affirmation of U.S. sovereignty. The war, fought against Great Britain from 1812 to 1815, ended with the Treaty of Ghent, restoring pre-war boundaries without major territorial changes. Although neither side achieved a clear victory, the United States emerged with a boost in national pride, especially following the defense of Fort McHenry, which inspired "The Star-Spangled Banner." The conflict also encouraged American manufacturing and exposed the need for better infrastructure, influencing subsequent economic and political development in the nation.
