Der Mythus des 20. Jahrhunderts
Although Hitler originally wrote mostly for the followers of National Socialism, it grew in popularity after he rose to power. (Two other books written by party members, Gottfried Feder's "Breaking The Interest Slavery" and Alfred Rosenberg's "The Myth of the Twentieth Century", have since lapsed into comparative literary obscurity.) Hitler had made about 1.2 million Reichsmarks from the income of the book by 1933 (), when the average annual income of a teacher was about 4,800 Marks (). He accumulated a tax debt of 405,500 Reichsmark (very roughly in 2015 1.1 million GBP, 1.4 million EUR, 1.5 million USD) from the sale of about 240,000 copies before he became chancellor in 1933 (at which time his debt was waived).
