The diary lay forgotten for over a decade until it was found in early 1936 by the late Hitler's half-niece, Geli Raubal. Having recently read an article about Propyläen publishing house's plans for it's new book series, she send them the diary. Propyläen's team of authors then turned it into the first volume of the 'Mein Kampf' series. The book, like the others of the 'Mein Kampf' series, sold very well, despite the economic crisis.
Two years later, following the widespread popularity of the bestselling series produced by Propyläen, film director Wunderkind Leni Riefenstahl resolved to turn the material into a movie based on the accounts given. 'Unser Kampf', Our Struggle, boasted the highest production values hitherto seen.
