In the book, Hitler describes (talks about) his view of greater Germany. He also describes his future plan for Jews. When he came to power, in 1933, he realized (made happen) some of those plans. This resulted in a genocide known as The Holocaust. The book was given away for free at civil registry offices during the time when the Nazi government had power in Germany. The reason for giving the book away for free was because in part, the book was propaganda, and giving it away free was a way to recruit members.
