Following Germany’s defeat in World War I, Hitler noticed the effective nature of Allied propaganda during the war effort, dedicating three chapters to the study and practice of propaganda in his autobiographical manifesto, Mein Kampf. Propaganda played a large part in the rise of the Nazi Party in Germany, and guided public opinion to reduce the complexities of Germany’s loss of the First World War and subsequent economic turmoil to a simple ‘us versus them’ narrative. Nazi’s utilised propaganda to spread a message of nationalism and German racial superiority, and played on widespread German anti-Semitism by declaring war on ‘Jewish Marxism’. The party sort to eradicate democracy, pacifism, and internationalism from German society, and as a similar concept, tolerance saw a sharp decline with the rule of the Nazi Party also.
However use of propaganda wasn’t limited to Nazi Germany and proved to be the driving force through the war as all sides utilised it to both further their cause and damage the enemy's. Propaganda was used by Russians, the US, and Britain extensively during the war and went from merely morale boosting posters to elaborate campaigns against the enemy to cause confusion and doubt in their nation’s leadership. Propaganda evolved in nature and use during the war and became increasingly authoritarian even in Allied countries like the US and Britain, but propaganda widely utilised intolerances and fed into exaggerations and misappropriations in order to boost morale and nationalism.
