National Socialist Party " " Totalitarian fanatics bent on world conquest . The Borg of their day . . . no offense . " " " " None taken . " " The term Nazi was an abbreviation of the designation " Nationalsozialist " , used originally only for members and supporters of the " Nationalsozialistische Deutsche Arbeiterpartei " ( abbreviation : NSDAP ; English : National Socialist German Workers ' Party or National Socialist Party ) , a totalitarian fascist party in the nation - state of Germany , on Earth , in the early part of the 20th century . The Nazi Party became a tool for governmental domination , known as the Third Reich , by dictator Adolf Hitler who enforced policies of racial superiority and German dominance through various means such as the Nazi security organization known as the SS . Earth . Nazi Germany , part of the Axis Powers , was a feared symbol of power in the 1930s and 1940s , and were principal participants in the massive worldwide conflict which came to be known as World War II . They set a model for autocratic dictatorship , hatred and oppression that has rarely been matched in their thirst for conquest , brutality and intolerance towards their fellow man , as evidenced by their persecution and systematic extermination of whole populations they deemed inferior in their own society . The Nazi philosophy was shrouded in symbols and rituals , such as the swastika and " heiling " and the distinct uniforms . The latter was a greeting , originally derived from what was assumed to be the formal greeting within the Roman Empire . The Nazi regime also created and distributed a wide variety of medals and awards , many of which ( such as the Iron Cross ) were fairly well known centuries after the defeat of the Nazis in 1945 . Alternate timelines . The Temporal Cold War . In an alternate timeline created by multiple temporal incursion s by various factions in the Temporal Cold War , Nazi Germany launched a successful invasion on the United States . This timeline was initially created through the assassination of Vladimir Lenin in 1916 , preventing Russia from turning to communism . Not considering Russia to be a threat , Hitler was able to concentrate his war efforts on the West . France and England were conquered before the American East Coast by 1944 . However the advance was too hasty and that same year the Russian s were preparing to retake Moscow and Africa to be liberated . The Nazis were assisted by another Cold War faction , the Na ' kuhl , who promised to provide advanced technology to the Nazis in exchange for goods and materials with which to construct a temporal conduit to return to the future . The Na ' kuhl were eventually successful , and used the conduit to return to the 29th century , igniting the Cold War into an all - out conflict and resulting in the very alternate timeline to which the Na ' kuhl had traveled in the first place . This timeline was later negated by , having been transported from the year 2154 by temporal agent , which destroyed the conduit before the Na ' kuhl had a chance to utilize it . ( ) The Guardian of Forever . In yet another alternate timeline , the Nazi Party succeeded in taking over the world when Doctor McCoy traveled through the sentient time portal known as the Guardian of Forever , from 2267 to the year 1930 on Earth , where he saved the life of a social worker named Edith Keeler . Keeler would go on to form a massive pacifist movement in America , delaying that country ' s entry into World War II . As peace negotiations went on , the Nazis completed their heavy water experiments , and with the atomic bomb , and the V2 rockets to carry them , Nazi Germany took control of Earth . This timeline was later negated by Captain Kirk and Spock , who used the Guardian to travel back to a point prior to McCoy ' s arrival , and prevented him from saving Keeler . ( ) Ekos and Zeon . Even after the war and the abolishment of Nazis and their propaganda , groups of neo - Nazis occasionally arose from insular populaces . One latter - day neo - Nazi organization was started , as a twisted social experiment , by Human scientist John Gill on the planet Ekos . The Ekosian s embraced Gill ' s rhetoric , eventually turning their hatred towards their nearest planetary neighbors , the space - faring Zeon s . As a cultural observer sent undercover and alone to the planet Ekos , Gill inadvertently showed just how powerful and dangerous the Nazi message could be , centuries after the fall of Hitler ' s Third Reich . Finding the planet in anarchy , Gill violated the Prime Directive , interfering with the planet ' s society in an effort to stabilize the situation by producing a more benign version of the NSDAP , emulating its efficiency to restore order . However , a subordinate , Melakon , subtly seized power by chemical ly incapacitating Gill and manipulated the populace into the same brutal racial supremacist policies of the original . Zeons were expelled from the Ekosian planet , or worse , rounded up into camps , just as had been done to the Jews on Earth . Even Gill was not immune , as his own Nazi party he designed used him as a puppet , drugged and helpless , to hide their ownership of the true dictatorial power . A landing party from the Federation starship attempted to rectify the damage to that planet ' s society , removing Gill from power ( he was eventually killed by Melakon when he denounced the usurper and disavowed his genocidal policies ) , and allowing a resistance effort ( which included some very influential Party members ) to co - opt power from the decapitated Nazis . This is often quoted as a textbook example of the importance of the Prime Directive of non - interference , the dangers of technologically superior beings manipulating younger societies . ( ) Hirogen interests . A pack of Hirogen ships successfully captured the and forced the crew to participate in vast holodeck hunting simulations , brainwashing the crew to believe they were genuine characters in the holodecks while leaving a select minority outside to treat their wounds and create additional holobuffers throughout the ship . One of these simulations was of a Nazi occupied France during World War II . Various Hirogen hunters assumed the roles of Nazi officers and wore the uniforms of Nazi officers while working side by side with holographic simulated Nazis . The Hirogen , resenting his Alpha ' s decisions had been partly convinced by the Nazi vision of superiority , having found some commonality in their philosophies , attempted to kill the " Voyager " crew until he was killed by Captain Janeway .
