Star spangled banner march 3, 1931
On this day in 1931, President Herbert Hoover signed into law legislation making “The Star-Spangled Banner” the nation’s official national anthem.Francis Scott Key (1779-1843) composed the poem that became "The Star-Spangled Banner” on Sept. 14, 1814, after witnessing the massive overnight British bombardment of Fort McHenry in Baltimore harbor, a key assault during the War of 1812. Key, a lawyer, watched the siege while being detained aboard ship by British sailors. He penned the words after observing, with shock and awe, that the flag – with its 15 stars and 15 stripes – had survived the nearly 1,800-bomb assault.
