On September 14, 1814, Francis Scott Key pens a poem which is later set to music and in 1931 becomes America’s national anthem, “The Star-Spangled Banner.” The poem, originally titled “The Defence of Fort M’Henry,” was written after Key witnessed the Maryland fort being bombarded by the British during the War of 1812. Key was inspired by the sight of a lone U.S. flag still flying over Fort McHenry at daybreak, as reflected in the now-famous words of the “Star-Spangled Banner”: “And the rocket’s red glare, the bombs bursting in air, Gave proof through the night that our flag was still there.”

Francis Scott Key was born on August 1, 1779, at Terra Rubra, his family’s estate in Frederick County (now Carroll County), Maryland. He became a successful lawyer in Maryland and Washington, D.C., and was later appointed U.S. attorney for the District of Columbia.
