Triumph of the Will (German: Triumph des Willens) is a 1935 propaganda film directed, produced, edited and co-written by Leni Riefenstahl. It chronicles the 1934 Nazi Party Congress in Nuremberg, which was attended by more than 700,000 Nazi supporters. The film contains excerpts from speeches given by Nazi leaders at the Congress, including Adolf Hitler, Rudolf Hess and Julius Streicher, interspersed with footage of massed Sturmabteilung and Schutzstaffel troops and public reaction. Hitler commissioned the film and served as an unofficial executive producer; his name appears in the opening titles. The film's overriding theme is the return of Germany as a great power, with Hitler as the leader who will bring glory to the nation. Because the film was made after the 1934 Night of the Long Knives (on June 30) many prominent Sturmabteilung (SA) members are absent since they were murdered in that Party purge organized and orchestrated by Hitler to replace the SA (led by his rival Ernst Roehm) with the Schutzstaffeln (SS) as his main instrument of mass terror.
