The U.S. National Anthem History
The Star-Spangled Banner is the national anthem of the United States of America. To celebrate a victory over British forces during the War of 1812, U.S. soldiers raised a large American flag at Fort McHenry in Baltimore, Maryland, on September 14, 1814. Inspired by those events, Francis Scott Key wrote a poem called "Defence of Fort M'Henry," which eventually became the Star Spangled Banner and the United States national anthem.
