Governments engaged in the Great War learned
very quickly that modern warfare would require the
effective use of propaganda to sway public opinion. It was
no longer sufficient for a nation’s military to be the only
force in conflict now the entire populace – both civilian
and soldier – would combine into a national fighting
force. “Of the numerous lessons to be drawn from the First
World War, one of the most significant was that public
opinion could no longer be ignored as a determining factor
in the formulation of public policies” (Sanders ; Taylor
1). National morale would depend on how swiftly recruits
signed up and how much comfort and peace of mind
citizens would be willing to sacrifice.
