Rifles, grenades, and heavy machinery are the weapons of war, but there’s another, subtle and powerful form of warfare. Images, words, films, and even songs engage the hearts and minds of citizens to support wars.
The following posters are examples of persuasion used in the past to sway public opinion and sustain war efforts.
1. Fear is a powerful motivator. After all, it’s either them or us.
2. Nothing like a woman and child in imminent danger to jump-start our natural protective instincts.
3. This poster draws on the similarity of a child’s college fund.
4. Events like the massacre at Lidice gave Nazis a reputation for their brutality. This poster is a reminder of the atrocities that await should they invade American cities.
5. Posters like the one below alerted citizens to the presence of enemy spies lurking in everyday society. These posters reminded well-meaning citizens of the consequences careless talk may cause, such as compromising national security and troop safety.
6. “Uncle Sam” was extensively used during World War II. He was a fighter, a laborer, a recruiter and more.
7. “Avenge Pearl Harbor” was a popular cry after the surprise attack on Dec. 7, 1941.
8. Posters like the one below encouraged continued support for the war.
9. Humor was also used in propaganda posters.
10. But direct and emotional messages were more effective.
11. World War II took place during the golden era of comic books, which lasted from the late 1930s to the early 1950s. This poster made in the popular comic book style was a sure fire way to promote a message.
