Zweites Buch - Wikipedia
The
Zweites Buch (German:
[ˈtsvaɪ̯təs buːχ], "Second Book"), published in English as
Hitler's Secret Book and later as
Hitler's Second Book,
[1] is an unedited transcript of
Adolf Hitler's thoughts on
foreign policy written in 1928; it was written after
Mein Kampf and was not published in his lifetime.
Gerhard Weinberg speculates that the
Zweites Buch was not published in 1928 because
Mein Kampf did not sell well at that time and Hitler's publisher,
Franz-Eher-Verlag, would have told Hitler that a second book would hinder sales even more.
