The Great Depression
Fritz Kuhn (1896-1951), a German-born immigrant to the United States, was the head of the pro-Nazi German-American Bund in the late 1930s. The country's leading Nazi sympathizer, Kuhn called himself "America's Führer."
Under Kuhn's leadership, the German-American Bund sought to bring Nazi-style fascism to America. While Hitler certainly had his admirers in American society during the 1930s, the Bund was never successful at attracting support beyond the German ethnic community. In particular, Kuhn's virulent anti-Semitism may have been off-putting to potential American supporters.
