Civil War Origins: Memorial Day originated in the years following the Civil War, a conflict that claimed more lives than any other conflict in U.S. history and necessitated the establishment of the country's first national cemeteries.

Decoration Day: It was originally known as Decoration Day, from the tradition of decorating graves with flowers, wreaths, and flags. The first widespread observance of Decoration Day was on May 30, 1868, after a proclamation by General John A. Logan of the Grand Army of the Republic, an organization of Union Veterans.

Transition to Memorial Day: Over time, Decoration Day evolved to become Memorial Day, and it expanded to honor all Americans who died in military service, not just those from the Civil War. The name Memorial Day was first used in 1882 and became more common after World War II.

National Moment of Remembrance: In 2000, Congress established a National Moment of Remembrance, which asks Americans to pause for one minute at 3:00 PM local time on Memorial Day to reflect on the sacrifices of those who died in service to the nation.

Traditions: Common traditions include visiting cemeteries and memorials, holding family gatherings, and participating in parades. Volunteers often place American flags on graves of military personnel in national cemeteries.

Significance: Memorial Day serves as a time for Americans to reflect on the high cost of freedom and to honor those who have made the ultimate sacrifice in defense of the country. It is distinct from Veterans Day, which honors all U.S. military Veterans, not just those who died in service.
