Propaganda played a critical role during World War II, serving as a powerful tool for shaping public opinion and morale. Governments used propaganda to boost enlistment, promote war bonds, and encourage civilian support for the war effort. In Nazi Germany, propaganda emphasized Aryan supremacy and fueled hatred against Jews and other minorities, justifying horrific actions. In the U.S. and Allied nations, propaganda often highlighted heroic narratives and demonized the enemy to foster patriotism. It also facilitated the dissemination of information, though it frequently involved manipulation and censorship, revealing the darker sides of wartime governance and public perception.
