War propaganda refers to the use of information, ideas, or rumors deliberately spread to influence public opinion and support for a war. It often aims to boost morale, demonize the enemy, and encourage enlistment or financial support for military efforts. Governments and organizations utilize various media, including posters, films, and social media, to convey their messages. Throughout history, propaganda techniques have evolved, adapting to new technologies and societal changes. Notable examples include the Committee on Public Information during World War I and the use of radio broadcasts in World War II. These efforts shape perceptions and can significantly impact a nation’s involvement in conflict.
