"The Star-Spangled Banner" is the national anthem of the United
States. The lyrics came from the "Defence of Fort M’Henry", a
poem written on September 14, 1814, by 35-year-old lawyer and
amateur poet Francis Scott Key after witnessing the bombardment
of Fort McHenry by British ships of the Royal Navy in Outer
Baltimore Harbor in the Patapsco River during the Battle of
Baltimore in the War of 1812 (below). Key was inspired by the large
U.S. flag, with 15 stars and 15 stripes, known as the Star-Spangled
Banner, flying triumphantly above the fort during the U.S. victory.        

The poem was set to the tune of a popular British song written by
John Stafford Smith.
