About Star Spangled Banner
"The Star-Spangled Banner" is the national anthem of the United States. The lyrics come from "Defence of Fort M'Henry", a poem written in 1814 by the 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 the Chesapeake Bay during the Battle of Fort McHenry in the War of 1812.
The poem was set to the tune of a popular British song written by John Stafford Smith for the Anacreontic Society, a men's social club in London. "To Anacreon in Heaven (or "The Anacreontic Song"), with various lyrics, was already popular in the United States. Set to Key's poem and renamed "The Star-Spangled Banner", it would soon become a well-known American patriotic song.
