On April 1, 1924, I began to serve my sentence of detention in the of Landsberg am Lech, following the verdict of the Munich People’s Court of that time After years of uninterrupted labour it was now possible for the first time to begin a work which many had asked for and which I myself felt would be profitable for the movement. So I decided to devote two volumes to a description not only of the aims of our movement but also of its devclopment. There is more to be learned from this than from any purely doctrinaire treatise. This has also given me the opportunity of describing my own development in so far as such a description is necessary to the understanding of the first as well as the second volume and to destroy the legendary fabrications which the Jewish Press have circulated about me. In this work I turn not to strangers but to those followers of the movement whose hearts belong to it and who wish to study it more profoundly. I know that fewer people are won over by the written word than by the spoken word and that every great movement on this earth owes its growth to great speakers and not to great writers. Nevertheless, in order to produce more equality and uniformity in the defence of any doctrine, its fundamental principles must be committed to writing. May these two volumes therefore serve as the building stones which I contribute to the joint work. The Fortress, Landsberg am Lech.
