When did “The Star-Spangled Banner” become the national anthem for America?
The four-stanza song was adopted as the national anthem by the U.S. Congress in 1931. Francis Scott Key wrote the lyrics in 1814, taking the melody from an eighteenth-century drinking song called “To Anacreon in Heaven” by British composer John Stafford Smith. Anacreon was a Greek lyric poet [563-478 B.c.] associated with love and wine.
