The administrative structure of the Bund mimicked the regional administrative subdivision of the Nazi Party. The German American Bund divided the United States into three "Gaue": Gau Ost (East), Gau West and Gau Midwest. Together the three "Gaue" comprised 69 "Ortsgruppen" (local groups): 40 in Gau Ost (17 in New York), 10 in Gau West and 19 in Gau Midwest. Each Gau had its own "Gauleiter" and staff to direct the Bund operations in the region in accordance with the "Führerprinzip". The Bund's national headquarters was located at 178 East 85th Street in the New York City borough of Manhattan.
