Although it didn’t become an official national holiday until 1971, Memorial Day is rooted in an American tradition that dates back to the years following the Civil War. Often confused with Veterans Day, which pays tribute to all who have served in the United State Armed Forces, Memorial Day is intended to honor Americans who died in battle or as a result of wounds sustained in battle.
