State propaganda refers to information, ideas, or rumors deliberately spread by a government to influence public opinion and promote its policies. This can include various forms of media, such as television, radio, newspapers, and social media, aimed at shaping perceptions and attitudes toward the state and its actions. Governments often use state propaganda during times of conflict or political change to rally support, justify decisions, or suppress dissent. Historical examples include the use of propaganda by Nazi Germany and Soviet Union, where the state controlled information to maintain power and control over the populace.
