In the nineteenth century, many American communities and cities celebrated Independence Day with a ceremonial reading of the Declaration of Independence, which was usually followed by an oral address or speech dedicated to the celebration of independence and the heritage of the American Revolution and the Founding Fathers. On July 5, 1852, the Ladies’ Anti-Slavery Society of Rochester, New York, invited the Black abolitionist and civil rights leader Frederick Douglass to be the keynote speaker for their Independence Day celebration. The Fourth of July Speech, scheduled for Rochester’s Corinthian Hall, attracted an audience of 600. The meeting opened with a prayer and was followed by a reading of the Declaration of Independence. When Douglass finally came to the platform to deliver his speech, the event took a jarring turn. Douglass told his audience, “This Fourth of July is yours, not mine. You may rejoice, I must mourn.” And he asked them, “Do you mean, citizens, to mock me, by asking me to speak today?”

Within Douglass’ now-legendary address is what historian Philip S. Foner has called “probably the most moving passage in all of Douglass’ speeches.”

What, to the American slave, is your 4th of July? I answer: a day that reveals to him, more than all other days in the year, the gross injustice and cruelty to which he is the constant victim. To him, your celebration is a sham; your boasted liberty, an unholy license; your national greatness, swelling vanity; your sounds of rejoicing are empty and heartless; your denunciations of tyrants, brass fronted impudence; your shouts of liberty and equality, hollow mockery; your prayers and hymns, your sermons and thanksgivings, with all your religious parade, and solemnity, are, to him, mere bombast, fraud, deception, impiety, and hypocrisy—a thin veil to cover up crimes which would disgrace a nation of savages. There is not a nation on the earth guilty of practices, more shocking and bloody, than are the people of these United States, at this very hour.

On this and every July 4th, Americans might do well to re-read and reflect on Douglass’ famous message. It challenges us to move beyond the biases and blind spots of our own cultural privileges and consider those around us for whom, as Langston Hughes said, “America has never been America.”
