The nature of conflict, from the Civil War to World War I and then the Vietnam War, in some way, changed the character of Memorial Day. It is true that the core celebration of the dead who served their country has never changed, but conflicts also began to be known for those who went missing, particularly the Vietnam War. Others also began to see the holiday as a time to reflect on their departed loved ones. What began as an unofficial springtime tradition for remembrance transformed into a public holiday and celebration after General Logan's declaration. The years after World War I finally saw the holiday gaining greater significance
to some Southern states and beginning to reflect the remembrance of the dead in all conflicts.
