The most fateful book in world history. Ninety years have passed since the first publication of Adolf Hitler's Mein Kampf. For twenty years, the book brought death and destruction. It was banned for seventy years. The whole world knows the title, but most people only know about the content of Mein Kampf through hearsay. What does it actually say? How does reading this book, which had such a sinister impact on the 20th century, change a person? How dangerous is it really today? The author Matthias Kessler undertook a personal experiment. Rare photos from a private collection in Munich complete his extraordinary odyssey into Germany's past and psyche. It was once called The Book of the Germans. On January 1, 2016, the usage rights to Mein Kampf will be released, seventy years after Adolf Hitler's death. This is not just another biography of Hitler.
