Understanding the role of propaganda in wartime is integral to recognizing how governments shape public perception and morale. Propaganda serves to legitimize conflicts, bolster national identity, and galvanize support for military efforts. During both World Wars, nations employed propaganda to portray enemies negatively and promote wartime contributions, using various media, including posters, films, and speeches. The effectiveness of propaganda lies in its ability to simplify complex issues, evoke emotional responses, and unify public sentiment. Understanding this role highlights the intersection of media, politics, and public opinion in shaping historical narratives and outcomes in conflicts.
