"The Star-Spangled Banner" is the national anthem of the United States. Written by Francis Scott Key in 1814, it was inspired by the sight of the American flag flying over Fort McHenry after a night of intense battle during the War of 1812. The song reflects themes of resilience and patriotism. The anthem consists of four verses, but typically only the first verse is sung at public events. Its melody is based on a British drinking song called "To Anacreon in Heaven." "The Star-Spangled Banner" was officially adopted as the national anthem in 1931.
