Political propaganda posters are printed visual materials created to influence public opinion, rally support, or promote specific ideologies, leaders, or causes. Widely used in the 20th century—especially during wartime, revolutions, and elections—these posters combined bold imagery, striking slogans, and national symbols to deliver powerful, often emotional messages. Produced by governments, political parties, or activist groups, they were designed for mass distribution and public display to shape attitudes, boost morale, or demonise opponents. Today, vintage propaganda posters are studied for their graphic design, psychological impact, and historical context, reflecting the politics and values of their time.
