Propaganda played a critical role during World War II as governments sought to influence public opinion and mobilize support for the war effort. Nations used various media, including posters, films, and radio broadcasts, to promote unity, encourage enlistment, and boost production on the home front. Propaganda often depicted the enemy in a negative light, fostering a sense of patriotism and justifying military actions. Additionally, it aimed to maintain morale among civilians and soldiers alike. Both the Allies and Axis powers utilized propaganda to disseminate ideology, rally support, and demonize opponents, ultimately shaping public perception and influencing wartime behavior.
