How did propaganda change people who lived during ww1?

During World War I, Propaganda significantly influenced public perception and behavior by shaping attitudes toward the war and the enemy. Governments used posters, films, and speeches to foster nationalism, encourage enlistment, and promote support for war efforts, often portraying soldiers as heroes and enemies as villains. This manipulation of information not only galvanized public support but also created a sense of collective identity and duty among citizens. Ultimately, propaganda helped to sustain morale on the home front while dehumanizing the enemy, which justified the war and its sacrifices.
