On September 13, 2014, Fort McHenry in Baltimore held a 200th anniversary celebration to mark the writing of the âStar Spangled Banner.â (Getty) âThe Star Spangled Bannerâ has been the official U.S. National Anthem since 1931 and is commonly heard today before sporting events and other patriotic gatherings. The lyrics â at least those to the first verse â have become ingrained in Americaâs culture, as much as apple pie and baseball.
Although the poem has four stanzas, only the first is commonly sung today. The Star-Spangled Banner was recognized for official use by the United States Navy in 1889, and by U.S. President Woodrow Wilson in 1916, and was made the national anthem by a congressional resolution on March 3, 1931 (46 Stat. 1508, codified at 36 U.S.C. Â§ 301), which was signed by President Herbert Hoover.
