Agreed that Memorial Day isn't a "celebration", but a commemoration. So few people realize who really started the holiday, or why they did.
"Although May 30, 1868 is cited as the first national commemoration of Memorial Day at Arlington National Cemetery, events led by African Americans in Charleston, South Carolina to decorate the graves of fallen Civil War soldiers occurred on May 1, 1865, less than a month after the Confederacy surrendered.
Reports of this early version of Memorial Day or “Decoration Day” as it was called, were rediscovered in the Harvard University archives in the late 1990s by historian David Blight, author of the 2018 biography Frederick Douglass: Prophet of Freedom.
To quote from history.com:
When Charleston fell and Confederate troops evacuated the badly damaged city, those freed from enslavement remained. One of the first things those emancipated men and women did was to give the fallen Union prisoners a proper burial. They exhumed the mass grave and reinterred the bodies in a new cemetery with a tall, whitewashed fence inscribed with the words: “Martyrs of the Race Course.”
And then on May 1, 1865, something even more extraordinary happened. According to two reports that Blight found in The New York Tribune and The Charleston Courier, a crowd of 10,000 people, mostly freed slaves with some white missionaries, staged a parade around the race track.
Three thousand Black schoolchi!dren carried bouquets of flowers and sang “John Brown’s Body.” Members of the famed 54th Massachusetts and other Black Union regiments were in attendance and performed double-time marches. Black ministers recited verses from the Bible.
Despite the size of the gathering and newspaper coverage, the memory of this event was “suppressed by white Charlestonians in favor of their own version of the day,” Blight stated in the New York Times in 2011.
On May 31, 2010, near a reflecting pool at Hampton Park, the city of Charleston reclaimed this history by installing a plaque commemorating the site as the place where Black Charlestonians held the first Memorial Day on May 1, 1865."
