The Holocaust was the systematic, bureaucratic, state-sponsored persecution and murder of approximately six million Jews by the Nazi regime and its collaborators. "Holocaust" is a word of Greek origin meaning "sacrifice by fire." The Nazis, who came to power in Germany in January 1933, believed that Germans were "racially superior" and that the Jews, deemed "inferior," were an alien threat to the so-called German racial community.
During the era of the Holocaust, German authorities also targeted other groups because of their perceived "racial inferiority": Roma (Gypsies), the disabled, and some of the Slavic peoples (Poles, Russians, and others). Other groups were persecuted on political, ideological, and behavioral grounds, among them Communists, Socialists, Jehovah's Witnesses, and homosexuals.

This is part of my SHEP reaserch because it is refering to the infamous holocaust that took place years ago and is very important to the film not only becuase in the first of its 3 instllments it is feautred at the beggining but also becuase the mutants are also treated like second class citizens and abonded from society much like the jews were at the time by hitler.
