Confederate Memorial Day, also known as Confederate Decoration Day (Tennessee) and Confederate Heroes Day (Texas), is an official holiday or observance day in a number of states in the Southern United States as a day to honor those who died fighting for the Confederate States of America during the American Civil War.
On April 25, 1866, women in Columbus, Mississippi laid flowers on the graves of both the Union and Confederate dead in the city’s cemetery. The early Confederate Memorial Day celebrations were simple, somber occasions for veterans and their families to honor the dead and tend to local cemeteries. By 1890, there was a shift from the emphasis on honoring specific soldiers to a public commemoration of the lost Confederate cause. Changes in the ceremony’s hymns and speeches reflect an evolution of the ritual into a symbol of cultural renewal and conservatism in the South. By 1913, Blight argues, the theme of American nationalism shared equal time with the Lost Cause.
In 2021 Confederate Memorial Day in Mississippi (State holiday) in USA falls on April 26.
