Francis Scott Key wrote the poem in 1814.

"On September 14, 1814, U.S. soldiers at Baltimore's Fort McHenry raised a huge American flag to celebrate a crucial victory over British forces during the War of 1812. The sight of those "broad stripes and bright stars" inspired Francis Scott Key to write a song that eventually became the United States national anthem"
