IMPORTANT: This book is sold strictly for educational and research purposes, with the objective of studying the history of antisemitism from a scholarly and objective perspective. We explicitly distance ourselves from the antisemitic ideas, views, and opinions contained within this volume. Furthermore, we strongly condemn any sympathy for, or glorification of, antisemitism in any form whatsoever. This English translation of Das Rätsel des jüdischen Erfolges is a work of antisemitic propaganda by Theodor Fritsch, published under the pseudonym F. Roderich-Stoltheim. It presents discriminatory stereotypes and conspiracy theories about Jewish people, commerce, finance, religion and social influence, falsely attributing complex economic and historical developments to supposed collective Jewish characteristics. The book reflects the racial antisemitism prevalent in German nationalist circles in the early twentieth century and is relevant today primarily as a historical source for the study of antisemitic ideology and propaganda. Theodor Fritsch (1852-1933) was a German publisher and antisemitic political agitator. He disseminated antisemitic and völkisch ideology through books and periodicals and was associated with the racial-nationalist movement in Germany. The pseudonym Roderich-Stoltheim was used for several of his writings.
