The Nazis considered Native Americans, especially the Sioux, and by extension all Native Americans to be Aryans. This was reflected in 1930s German westerns such as Der Kaiser von Kalifornien (translated as The Emperor of California), which contained highly sympathetic portrayals of Native Americans, unlike in the United States, where they were depicted as bloodthirsty savages in films.
Incredibly, several Nazi propagandists went to the Nth degree and openly declared that Germany would return expropriated land to the Indians, while Goebbels predicted they possessed little loyalty to America and would rather rebel than fight against Germany.
