PROPAGANDA

Propaganda is a form of communication that is aimed at influencing the attitude of a community toward some cause or position.
As opposed to impartially providing information, propaganda, in its most basic sense, presents information primarily to influence an audience. Propaganda often presents facts selectively (thus possibly lying by omission) to encourage a particular synthesis, or uses loaded messages to produce an emotional rather than rational response to the information presented. The desired result is a change of the attitude toward the subject in the target audience to further a political agenda. Propaganda can be used as a form of political warfare.

I think the Nazis and Hitler used Propaganda to appeal to the people more. They used it to make people think that the Nazis were the best party, and a more promising party. They also made it so that they would have more peaceful image. The second reason is to make people agree with their thoughts, such as, 'the Jews are the ones who should be blamed'. The Nazis made poster showing that the Jews are the bad ones, and that they should get the Jews out of their community.
