Memorial Day in the United States. It is a federal holiday established to honor military veterans who died in wars fought by American forces.
Celebrations honoring Civil War heroes started the year after the war ended. The establishment of a public holiday was meant to unify the celebration as a national day of remembrance instead of a holiday celebrated separately by the Union and Confederate states. By the late 19th century, the holiday became known as Memorial Day and was expanded to include the deceased veterans of all the wars fought by American forces. In 1971, Memorial Day became a federal holiday.
