Hitler served only nine months of his five-year term. While in prison, he wrote the first volume of Mein Kampf. It was partly an autobiographical book although filled with glorified inaccuracies, self-serving half-truths and outright revisionism which also detailed his views on the future of the German people. He reserved the brunt of his vituperation for the Jews, whom he portrayed as responsible for all of the problems and evils of the world, particularly democracy, Communism, and internationalism, as well as Germany's defeat in the War. Jews were the German nation's true enemy, he wrote. As such, they were not a race, but an anti-race.
