Walt Disney was commissioned by the US government during World War I and World War II to create propaganda cartoons. Over 90% of Disney's employees worked on producing training and propaganda films. Characters like Mickey Mouse and Donald Duck delivered pro-American messages and helped turn public opinion against enemies like Nazi Germany. One famous short film, "Der Fuehrer's Face" from 1943, depicted Donald Duck having a nightmare that he was a Nazi worker. These propaganda cartoons helped boost American morale during the wars.
