Zweites Buch was Hitler's second book, after the publication of Mein Kampf, which exists for the most part in outline and remained unpublished until 1961. Its tentative title was The Monumental History of Mankind. The focus of the outline was to blame "Judah" for all the pitfalls and failings of humanity in history.
