During what war was the star spangled banner written

According to different websites, the star spangled banner was written in the War of 1812

More details:

On September 14, 1814, Francis Scott Key pens a poem which is later set to music and in 1931 becomes America's national anthem, “The Star-Spangled Banner.” The poem, originally titled “The Defence of Fort M'Henry,” was written after Key witnessed the Maryland fort being bombarded by the British during the War of 1812.
