After Hitler's rise to power it gained enormous popularity and virtually became a Bible of every Nazi, or a member of the NSDAP. Sales of Mein Kampf earned Hitler millions; however many of those who purchased it never read it; many bought it simply to show their allegiance to Hitler, gain position in Nazism and avoid the attentions of the Gestapo. Many found it (and many still find it today) a lengthy and boring text. Much of the autobiographical material was distorted or fabricated by Hitler.
