Nazi Germany discriminated against and persecuted people on the basis of their race or ethnicity (actual or perceived), religious affiliation, political beliefs, sexual orientation, and, where applicable, mental or physical disabilities. Discrimination was institutionalized through legislation under the Nazi Party and perpetrated at an industrial scale, culminating in the Holocaust. The vast majority of the Nazi regime's victims were Jewish, Romani, or Slavic. Jews, along with some Romani populations, were deemed unfit for society on racial or ethnic grounds and largely confined to ghettos, then rounded up and deported to concentration or extermination camps. The beginning of World War II marked a colossal escalation in the Nazis' efforts to eliminate "inferior" communities across German-occupied Europe, with methods including: non-judicial incarceration, confiscation of property, forced labour (and extermination through hard labour), sexual slavery, human experimentation, malnourishment, and execution by death squads. For Jews, in particular, the Nazis' goal was total extermination—the genocide of the Jewish people, first in Europe and eventually in other parts of the world. This was presented by Adolf Hitler as the "Final Solution" to the Jewish question. According to Alex J. Kay, the groups subjected to mass killing by Nazi Germany, on the order of tens of thousands of victims or more, were 300,000 disabled people, as many as 100,000 Polish elites, nearly six million European Jews, 200,000 Romani people, at least 2 million Soviet urban residents targeted by the hunger policy, nearly 3.3 million Soviet prisoners of war, about 1 million rural inhabitants during anti-partisan warfare (excluding actual partisans), and 185,000 Polish civilians killed during and after the Warsaw Uprising. The total number of deaths from mass killing would thus amount to at least 13 million. Kay argues that all these groups, including Jews, "were regarded by the Nazi regime in one way or another as a potential threat" to Germany's war effort. However, viewing them as a threat was informed by Nazi racial theory, making it hard to separate racist versus strategic reasons for killing. Nazi policies in the occupied eastern territories resulted in the deaths of tens of millions of people, especially during Germany's invasion of the Soviet Union, which began in 1941 and opened up the Eastern Front, where 35% to 45% of all World War II casualties occurred.
Scope of usage
While the term Holocaust generally refers to the systematic mass-murder of the Jewish people in German-occupied Europe, the Nazis also murdered a large number of non-Jewish people who were also considered subhuman (Untermenschen) or undesirable. Some victims belonged to several categories targeted for persecution, e.g. an assimilated Jew who was a member of a communist party or someone of Jewish ancestry who identified as a Jehovah's Witness. Non-Jewish victims of Nazism included Slavs (e.g. Russians, Belarusians, Poles, Ukrainians and Serbs), the Romani (gypsies), LGBT people; mentally or physically disabled people; Soviet POWs, Roman Catholics, Jehovah's Witnesses, Spanish Republicans, Freemasons, people of color (especially the Afro-German Mischlinge, called "Rhineland bastards" by Hitler and the Nazi regime), and other minorities not considered Aryan (Herrenvolk, or part of the "master race"); leftists, communists, trade unionists, social democrats, socialists, anarchists, and other dissidents. Taking into account all of the victims of persecution, the Nazis systematically murdered an estimated six million Jews and millions of others during the war. Donald Niewyk suggests that the broadest definition, including Soviet civilian deaths, would produce a total of 17 million victims. Despite widely varying treatment (some groups were actively targeted for genocide while others were not), some died in concentration camps such as Dachau and others from various forms of Nazi brutality. According to extensive documentation (written and photographic) left by the Nazis, eyewitness testimony by survivors, perpetrators and bystanders, and records of the occupied countries, most perished in death camps such as Auschwitz-Birkenau.
Racial/ethnic or national groups
Jews
The military campaign to displace persons like the Jews from Germany and other German-held territories during World War II, often with extreme brutality, is known as the Holocaust. It was carried out primarily by German forces and collaborators, German and non-German. Early in the war, millions of Jews were concentrated in urban ghettos. In 1941, Jews were massacred, and by December, Hitler had decided to exterminate all Jews living in Europe at that time. The European Jewish population was reduced from 9,740,000 to 3,642,000; the world's Jewish population was reduced by one-third, from roughly 16.6 million in 1939 to about 11 million in 1946. The extermination of Jews had been a priority to the Nazis, regardless of the consequences. In January 1942, during the Wannsee Conference, several Nazi leaders discussed the details of the "Final Solution to the Jewish Question" (Endlösung der Judenfrage) and German State Secretary Josef Bühler urged conference chairman Reinhard Heydrich to proceed with the Final Solution in the General Government. Jewish populations were systematically deported from the ghettos and the occupied territories to the seven camps designated as Vernichtungslager (extermination camps):
Auschwitz-Birkenau Belzec Chelmno Majdanek Maly Trostenets Sobibór Treblinka In 1978, Sebastian Haffner wrote that in December 1941, Hitler began to accept the failure of his primary goal—to dominate Europe, after his declaration of war against the United States, and his withdrawal—was compensated for by his secondary goal: the extermination of the Jews. As the Nazi war machine faltered during the war's final years, military resources such as fuel, transport, munitions, soldiers and industrial resources were still diverted from the fronts to the death camps.
