The Nazi propaganda film Triumph of the Will, directed by Leni Riefenstahl, premiered in Berlin.

Propaganda was a tool of the Nazi Party in Germany from its earliest days to the end of the regime in May 1945 at the end of World War II in Europe. As the party gained power, the scope and efficacy of its propaganda grew and permeated an increasing amount of space in Germany and, eventually, beyond.

Triumph of the Will is a 1935 German Nazi propaganda film directed, produced, edited and co-written by Leni Riefenstahl. Adolf Hitler commissioned the film and served as an unofficial executive producer; his name appears in the opening titles. It chronicles the 1934 Nazi Party Congress (rally) in Nuremberg, which was attended by more than 700,000 Nazi supporters. The film contains excerpts of speeches given by Nazi leaders at the Congress, including Hitler, Rudolf Hess and Julius Streicher, interspersed with footage of massed Sturmabteilung (SA) and Schutzstaffel (SS) troops and public reaction. Its overriding theme is the return of Germany as a great power with Hitler as its leader. The film was produced after the Night of the Long Knives, and many formerly prominent SA members are absent.

Helene Bertha Amalie "Leni" Riefenstahl was a German film director, producer, screenwriter, editor, photographer, and actress. She is considered one of the most controversial personalities in film history. Regarded by many critics as an "innovative filmmaker and creative aesthete", she is also criticized for her works in the service of propaganda during the Nazi era.
