Propaganda involves systematically spreading information to influence beliefs and attitudes. It often promotes a one-sided view to gain support and is used to spread ideology. Propaganda employs persuasive language and appeals, and involves strong emotional appeals. It can be found everywhere, spread through various media like posters, slogans, speeches, and is prevalent during wartime to promote messages like conscription, animosity toward enemies, and conservation. The purposes of war propaganda are to promote political messages, gain support, rouse animosity toward enemies, use scare tactics, conserve resources, and encourage production.
