The Nazi regime routinely compared Jews to animals in propaganda to dehumanize and incite hatred. Posters depicted Jews as vermin like rats to suggest they were disease carriers. In Mein Kampf, Hitler described Jews as a parasitic "anti-race" driven by base instincts, calling for their extermination. Nazis used terms like "Untermenschen" (subhumans) to portray Jews as inferior and justify persecution. These comparisons aimed to strip Jews of humanity, making it easier to rationalize the Holocaust.
