Space Nazis

Space Nazis is a recurring trope in many science fiction works dealing with World War II or World War III like situations.

Even before World War II, Edgar Rice Burroughs satirized the Nazis by placing a fascist political faction called "Zanis" on the planet Venus in Carson of Venus, published in serialized form in 1938.

The theme of Nazis escaping into space was already evident in Robert A. Heinlein's Rocket Ship Galileo, published two years after the end of World War II, wherein Nazis colonized the Moon after escape from their defeat on Earth. Later books with a similar premise often involve an alternate history featuring the Nazis winning World War II or extraterrestrials traveling back in time to supply advanced technology to one side (usually Germany). Most of Norman Spinrad's The Iron Dream consists of novel written by alternate-history Adolf Hitler who became a science fiction writer, which ends with cloned SS supermen initiating a galactic empire.

In the future solar system of Jack Williamson's "Seetee Ship", the planet Mars is colonized by Nazi Germans and Fascist Italians, and its main public holiday is "Hitler Day" which is often the occasion of bloody riots; the Nazi Mars is one of the malevolent space powers seeking to oppress the book's Liberty-minded Asteroid Belt miners.

Other premises include a splinter group of Nazis (or their ideology) being introduced to a previously benign planet. In some cases the Nazis have merely adapted their already advanced technology to reach the Moon.
