In what year did Francis Scott Key write "The Star Spangled Banner"?

Francis Scott Key wrote "The Star Spangled Banner" in 1814, following the bombardment of Fort McHenry during the War of 1812. This event inspired him to pen the poem, originally titled "Defence of Fort M'Henry," which later became the national anthem of the United States. The historical context is essential, as the poem captures the resilience and spirit of the American people during a significant conflict in their early history. The year 1812 is associated with the beginning of the war, but it was the specific events of September 13-14, 1814, that motivated Key to write the lyrics. This makes 1814 a pivotal year, marking both a critical moment in American history and the creation of a symbol of national pride. Other years mentioned do not align with the time frame of Key's inspiration or the composition of the anthem itself.
