Question

When did Francis S. Key's poem become the national anthem?

Answer 1

Francis Scott Key wrote 'In Defense of Fort McHenry' in 1814, inspired by the resilience of U.S. forces and the flag at Fort McHenry. The poem became the U.S. national anthem, 'The Star-Spangled Banner', on March 3, 1931.

Step-by-step explanation:

Francis Scott Key's poem, In Defense of Fort McHenry, was written after the British bombardment of Baltimore's Fort McHenry in 1814. Key was moved by the resilience of the American forces and the sight of the American flag still waving after the battle. His poem was later set to the melody of a well-known British song and it officially became the U.S. national anthem, known as The Star-Spangled Banner, on March 3, 1931.
