Beginning with discrimination, the Holocaust grew to Jewish people being separated from their communities, until later being viewed as less than human and murdered. Nazis sought to eliminate the entire Jewish population of Jews from Europe (around 11 million). Nazism spread from Germany to Eastern Europe. Some of the camps best known for killing (Chelmno, Belzec, Treblinka, and the most notorious of all the death camps, Auschwitz, a camp that killed a million Jews) were in Poland. Camps were not only for Jews, though that was the majority, camps were also occupied by Roma (Gypsies), Africans, homosexuals, and communists. Extermination included starvation, gas chambers, disease, and firing squads.
