Explanation:

Nazi propaganda was the coordinated attempt of the Nazi party to influence German public opinion through the use of propaganda in the media. It was used by the Nazi party and later, after the rise to power of Adolf Hitler, by the government of Germany until the end of the Second World War. The cinema / TV / radio as a propaganda tool was used by both sides before and during the war. Nazi propaganda provided a crucial instrument for acquiring and maintaining power, as well as for the implementation of its policies, including the prosecution of total war and the extermination of millions of people during the Holocaust and during the occupation of the Soviet Union.

Likewise, he presented common themes among countries at war: the imminent defeat of his enemies, the need for security, etc. The newsreels were also used to win support for the Nazi cause. Leni Riefenstahl was probably the most famous propagandist: her film The triumph of the will is one of the best known examples of propaganda in the history of cinema. This film was not only popular in the Third Reich, but has continued to influence films, documentaries and commercials to this day.
