The story, as most of us are told, is that Francis Scott Key was a prisoner on a British ship during the War of 1812 and wrote this poem while watching the American troops battle back the invading British in Baltimore. That—as is the case with 99 percent of history that is taught in public schools and regurgitated by the mainstream press—is less than half the story.

To understand the full “Star-Spangled Banner” story, you have to understand the author. Key was an aristocrat and city prosecutor in Washington, D.C. He was, like most enlightened men at the time, not against slavery; he just thought that since blacks were mentally inferior, masters should treat them with more Christian kindness. He supported sending free blacks (not slaves) back to Africa and, with a few exceptions, was about as pro-slavery, anti-black and anti-abolitionist as you could get at the time.

Of particular note was Key’s opposition to the idea of the Colonial Marines. The Marines were a battalion of runaway slaves who joined with the British Royal Army in exchange for their freedom. The Marines were not only a terrifying example of what slaves would do if given the chance, but also a repudiation of the white superiority that men like Key were so invested in.

All of these ideas and concepts came together around Aug. 24, 1815, at the Battle of Bladensburg, where Key, who was serving as a lieutenant at the time, ran into a battalion of Colonial Marines. His troops were taken to the woodshed by the very black folks he disdained, and he fled back to his home in Georgetown to lick his wounds. The British troops, emboldened by their victory in Bladensburg, then marched into Washington, D.C., burning the Library of Congress, the Capitol Building and the White House. You can imagine that Key was very much in his feelings seeing black soldiers trampling on the city he so desperately loved.
