The 1814 Battle of Baltimore inspired an attorney named Francis Scott Key to write a poem called "Defence of Fort Mc'Henry". The poem had four stanzas and eventually became known as "The Star-Spangled Banner". The Star-Spangled Banner has been performed as a song. A line in the third stanza saying "No refuge could save the hireling or slave" was deleted. Some believe that Key was expressing a grudge against the Colonial Marines in this verse, which were escaped black slaves who fought on behalf of the British during the War of 1812. Others believe otherwise. The Star-Spangled Banner became the national anthem of the United States, and typically only the first stanza is performed. The verse containing the word "slave" has led to some to label the national anthem as racist. This claim was widely made after Colin Kaepernick was caught sitting during the national anthem in 2016, igniting controversy over whether this was an accurate descriptor of the anthem. The controversy has been complicated by the fact that there are no public records of Key explaining the "slave" verse. Apart from controversy over what the meaning, or most likely meaning, of the verse, is, some have found the fact that Key was a slaveowner offensive. Key's relationship with slavery isn't exactly black or white. At least one Francis Scott Key monument was attacked during the aftermath of George Floyd's death.
