The classic Hollywood epic Gone With the Wind aroused a powerful surge of admiration and romanticism in audiences when it was first released in 1939. But it sent one of its biggest enthusiasts, Nazi minister of propaganda Joseph Goebbels, into a jealous rage. The German version of the picture (Vom Winde verweht) was reportedly one of Adolf Hitler’s favorite films, but, for Goebbels, it was a reminder of how far from beguiling the budding Nazi film industry was by comparison. “Goebbels,” as Life magazine reported in 1941, “would not even allow party officials to see it for fear that they might contrast it too unfavorably with the trashy but expensive films now being produced in Germany.”

But Gone With the Wind was not the only thing the Nazi elite admired when it came to the American South. According to historians Johnpeter Horst Grill and Robert L. Jenkins, “the American South, with its long-established system of white supremacy, was a source of interest to the Nazis as they, too, sought to work out their own system of Aryan supremacy.”

For the Nazis, the South represented a sociopolitical structure that had successfully maintained the separation between the races for centuries. In the 1930s, Nazi publications, which were anti-black in addition to being anti-Semitic, praised the “southern way,” pointing out that many Americans were also working against “racial bastardization,” evident from, among other things, the 30 or so U.S. states that had legal restrictions on interracial marriage. Hitler himself greatly admired America’s “wholesome aversion for the Negroes and the colored races in general” and warned of German culture being “negrified.”
