Although the German-American Bund received extensive press coverage during its existence and monographs of American politics in the 1930's refer to the Bund's activities, there has been no thorough examination of the charge that the Bund was a fifth column organization responsible to German authorities. This six-chapter study traces the Bund's history with an emphasis on determining the motivation of Bundists and the nature of the relationship between the Bund and the Third Reich. The conclusions are twofold. First, the Third Reich repeatedly discouraged the Bundists and attempted to dissociate itself from the Bund. Second, the Bund's commitment to Deutschtum through its endeavors to assist the German nation and the Third Reich contributed to American hatred of National Socialism.
