NUEVA GERMANIA, Paraguay — The year was 1887 when two of the best-known German anti-Semites of the time put down stakes here in Paraguay’s remote jungle with 14 German families screened for their racial purity.

The team of Bernhard Förster and his wife, Elisabeth, the sister of the philosopher Friedrich Nietzsche, had an ambitious plan: nothing less than the establishment of a colony from which an advance contingent of Aryans could forge a claim to the entire South American continent.

But the continent had other plans for this new Fatherland.

“Some were able to survive,” said Lidia Fischer, 38, a blonde-haired descendant of a family that was among Nueva Germania’s first settlers. Those pioneers struggled with disease, failed crops, infighting and the megalomania of the Försters, who lorded over the colony from an elegant mansion called the Försterhof.
