Francis Scott Key witnessed the British bombardment of Fort McHenry in Baltimore Harbor on September 13-14, 1814, during the War of 1812. Detained on a British ship during the attack, he watched through the night as shells lit the sky. When dawn broke and the American flag still flew over the fort, Key was moved to compose the poem "Defence of Fort McHenry," which would become one of the most enduring texts in American musical history.
Key's words were paired with an existing British melody, and the song spread rapidly across the nation. For music educators, his text remains a powerful vehicle for teaching American history, developing vocal technique, and fostering meaningful ensemble work. The song's emotional weight and historical significance make it a staple of patriotic programming.
