Candidate passages:
The number of black people in Germany when the Nazis came to power is variously estimated at 5,000–25,000.
It is not clear whether these figures included Asians.
According to the United States Holocaust Memorial Museum, Washington, D.C., "The fate of black people from 1933 to 1945 in Nazi Germany and in German-occupied territories ranged from isolation to persecution, sterilization, medical experimentation, incarceration, brutality, and murder.
However, there was no systematic program for their elimination as there was for Jews and other groups."
Meanwhile, Afrikaaners, Berbers, Iranians and Pre-Partition Indians were classified as Aryans, so not persecuted (see main article).
Racial restrictions were relaxed to the extent that Turkic peoples, Arabs and South Asians were recruited by the German military due to the shortage of manpower.
As Adolf Hitler came to power in Germany, Hermann participated in the underground movement against the Nazis.
She was member of the Internationaler Sozialistischer Kampfbund (ISK). 
Though the laws were primarily directed against Jews, other "non-Aryan" people were subject to the laws, and to other legislation concerned with racial hygiene.
The definition of "Aryan" was never fully defined as the term was too imprecise and ambiguous, it was attempted to be clarified over time in a number of judicial and executive decisions.
Jews were by definition non-Aryan, because of their Semitic origins, and the same was eventually applied to majority of Slavic nationalities who were considered "subhumans".
The Nazis considered a small percentage of people who the Nazis deemed in Eastern Europe to be descendants of ethnic German settlers and who underwent Germanised to be accepted as part of the Aryan "Herrenvolk" (Aryan master race).
Outside of Europe in North Africa, according to Alfred Rosenberg's racial theories ("The Myth of the Twentieth Century"), some of the Berbers, particularly the Kabyles, were to be classified as Aryans.
The Nazis portrayed Swedes, the Afrikaaners who are white European descendants of Dutch-speaking Boers in South Africa and higher-degree Northern/Western Europeans of South America (mainly from Uruguay, Brazil and Argentina) as ideal "Aryans" along with the German-speaking peoples of Greater Germany and Switzerland (the country was neutral during the war).
In Asia, only the Indo-Aryan and Indo-Iranian populations of British India, Iran, and Afghanistan were considered Aryan, although this did not affect the decision to target the Roma, who are of Indian origin because they were said to pose a threat to the Aryan race because of their racial mingling.
The number of black people in Germany when the Nazis came to power is variously estimated at 5,000 - 25,000.
According to the United States Holocaust Memorial Museum, Washington, D.C., “The fate of black people from 1933 to 1945 in Nazi Germany and in German-occupied territories ranged from isolation to persecution, sterilization, medical experimentation, incarceration, brutality, and murder.
However, there was no systematic program for their elimination as there was for Jews and other groups.”Prior to Hitler coming to power, black entertainers were popular in Germany, but the Nazis banned Jazz as ‘corrupt negro music’.
Mixed marriage and interracial sex became illegal, some blacks were used in medical experiments, and others mysteriously disappeared.
However, contrary to popular myth, black American sprinter Jesse Owens', who won four gold medals beating Aryan athletes at the 1936 Berlin Olympic games, faced less segregation there than in the USA, and felt snubbed by Roosevelt rather than by Hitler (see Jesse Owens#Berlin Olympics).
The July 1933 Law for the Prevention of Hereditarily Diseased Offspring—written by Ernst Rüdin and other theorists of "racial hygiene"—established "Genetic Health Courts" which decided on compulsory sterilization of "any person suffering from a hereditary disease."
These included, for the Nazis, those suffering from "Congenital Mental Deficiency", schizophrenia, "Manic-Depressive Insanity", "Hereditary Epilepsy", "Hereditary Chorea" (Huntington’s), Hereditary Blindness, Hereditary Deafness, "any severe hereditary deformity", as well as "any person suffering from severe alcoholism".
Further modifications of the law enforced sterilization of the "Rhineland bastards" (children of mixed German and African parentage). 
The film was made by Oswald for the Poverty Row studio Monogram Pictures.
Oswald was an exiled Austrian director who had fled Germany when the Nazis came to power going to France, Britain and finally to Hollywood where he made a handful of films. 
Gröning states that his childhood was one of "discipline, obedience" and "authority".
He joined the "Scharnhorst", the Stahlhelm's youth organization as a small boy in the 1930s, and later the Hitler Youth when the Nazis came to power in 1933.
Influenced by his family's values, he felt that Nazism was advantageous to Germany and believed that the Nazis "were the people who wanted the best for Germany and who did something about it."
He participated in the burning of books written by Jews and other authors that the Nazis considered degenerate in the belief that he was helping Germany free itself from an alien culture, and considered that National Socialism was having a positive effect on the economy, pointing to lower unemployment.
Gröning left school with high marks and began a traineeship as a bank clerk when he was 17, but war was declared shortly after he started employment and eight of the twenty clerks were immediately conscripted into the army.
This allowed the remaining trainees to further their banking careers in a relatively short amount of time, however despite these opportunities, Gröning and his colleagues were inspired by Germany's quick victories in France and Poland and wanted to contribute.
