Memorial Day was born out of necessity. After the American Civil War, a battered United States was faced with the task of burying and honoring the 600,000 to 800,000 Union and Confederate soldiers who had died in the single bloodiest military conflict in American history. The first national Memorial Day was held in Arlington National Cemetery on May 30, 1868, where both Union and Confederate soldiers are buried.
Several towns and cities across America claim to have observed their own earlier versions of Memorial Day, then known as “Decoration Day,” as early as 1864. The holiday’s original name is derived from the fact that decorating graves was and remains a central Memorial Day tradition.
But it wasn’t until a remarkable discovery in a dusty Harvard University archive the late 1990s that historians learned about a Memorial Day commemoration organized by a group of Black people freed from enslavement less than a month after the Confederacy surrendered in 1865. The event in Charleston, South Carolina, is one of the first Memorial Day observances in the country.
