Which book was a key element of Nazi ideological education?

Mein Kampf was a fundamental text for understanding Nazi ideology, as it was authored by Adolf Hitler himself. In this book, Hitler laid out his political philosophy, including his beliefs about race, nationalism, and the future of Germany. It was used as a tool for indoctrination and served to promote the ideas of Aryan superiority, anti-Semitism, and anti-communism, which were central to the goals of the Nazi party.

Additionally, Mein Kampf was widely distributed and was often required reading within the Nazi educational system, ensuring that its ideas permeated German society. This emphasis on racial purity and national strength resonated with many Germans at the time, contributing to the book's significance in Nazi propaganda and ideology. In contrast, the other choices represent literary works that do not align with or promote Nazi beliefs, thereby not fulfilling a similar educational role within Nazi Germany.
