Propaganda played a crucial role during World War I as governments sought to rally support and mobilize public opinion for the war effort. It was used to enlist soldiers, encourage war bonds, and promote national unity, while also demonizing the enemy. Posters, films, and news articles were crafted to create a specific narrative, highlighting heroism and the necessity of sacrifice. Propaganda shaped perceptions both domestically and internationally, impacting various aspects of society, such as women’s involvement in the workforce. Its effectiveness in influencing emotions and attitudes laid the foundation for future uses of propaganda in conflicts.
