Eugenics in the context of "NSDAP"

The Nazi Party, officially the National Socialist German Workers' Party (German: Nationalsozialistische Deutsche Arbeiterpartei  or NSDAP), was a far-right political party in Germany active between 1920 and 1945 that created and supported the ideology of Nazism. Its precursor, the German Workers' Party (Deutsche Arbeiterpartei; DAP), existed from 1919 to 1920. The Nazi Party emerged from the extremist German nationalist ("Völkisch nationalist"), racist, and populist Freikorps paramilitary culture, which fought against communist uprisings in post–World War I Germany. The party was created to draw workers away from communism and into völkisch nationalism. Initially, Nazi political strategy focused on anti-big business, anti-bourgeoisie, and anti-capitalism, disingenuously using socialist rhetoric to gain the support of the lower middle class; that was later downplayed to gain the support of business leaders. By the 1930s, the party's main focus shifted to antisemitic and anti-Marxist themes. The party had little popular support until the Great Depression, when worsening living standards and widespread unemployment drove Germans into political extremism.

Central to Nazism were themes of racial segregation expressed in the idea of a "people's community" (Volksgemeinschaft). The party aimed to unite "racially desirable" Germans as national comrades while excluding those deemed to be either political dissidents, physically or intellectually inferior, or of a foreign race (Fremdvölkische). The Nazis sought to strengthen the Germanic people, the "Aryan master race", through racial purity and eugenics, broad social welfare programs, and a collective subordination of individual rights, which could be sacrificed for the good of the state on behalf of the people. To protect the supposed purity and strength of the Aryan race, the Nazis sought to disenfranchise, segregate, and eventually exterminate Jews, Romani, Slavs, the physically and mentally disabled, homosexuals, Jehovah's Witnesses, and political opponents. The persecution reached its climax when the party-controlled German state set in motion the Final Solution – an industrial system of genocide that carried out mass murders of around 6 million Jews and millions of other targeted victims in what has become known as the Holocaust.

Nature versus nurture is a long-standing debate in biology and society about the relative influence on human beings of their genetic inheritance or biology (nature) and the environmental conditions of their development (nurture). Nature is what people think of as pre-wiring and is influenced by genetic inheritance and other biological factors. Nurture is generally taken as the influence of external factors after conception e.g. the product of exposure, experience and learning on an individual.

The phrase in its modern sense was popularized by the Victorian polymath Francis Galton, the modern founder of eugenics and behavioral genetics when he was discussing the influence of heredity and environment on social advancement. Galton was influenced by On the Origin of Species written by his half-cousin, the evolutionary biologist Charles Darwin. The complementary combination of the two concepts is an ancient concept (Ancient Greek: ἁπό φύσεως καὶ εὐτροφίας).

Nazism (/ˈnɑːtsiɪzəm, ˈnæt-/ NA(H)T-see-iz-əm), formally named National Socialism (NS; German: Nationalsozialismus, German: [natsi̯oˈnaːlzotsi̯aˌlɪsmʊs] ), is the far-right totalitarian ideology and practices associated with Adolf Hitler and the Nazi Party (NSDAP) in Germany. During Hitler's rise to power, it was frequently called Hitler Fascism and Hitlerism. The term "neo-Nazism" is applied to far-right groups formed after World War II with similar ideology.

Nazism is a form of fascism, with disdain for liberal democracy and the parliamentary system. Its beliefs include support for dictatorship, fervent antisemitism, anti-communism, anti-Slavism, anti-Romani sentiment, scientific racism, anti-Chinese sentiment, white supremacy, Nordicism, social Darwinism, homophobia, ableism, and eugenics. The Nazis' ultranationalism originated in pan-Germanism and the ethno-nationalist Völkisch movement, which had been prominent within German ultranationalism since the late 19th century. Nazism was influenced by the Freikorps paramilitary groups that emerged after Germany's defeat in World War I, from which the party's "cult of violence" came. It subscribed to pseudo-scientific theories of a racial hierarchy, identifying ethnic Germans as part of what the Nazis regarded as a Nordic Aryan master race. Nazism sought to overcome social divisions and create a homogeneous German society based on racial purity. The Nazis aimed to unite all Germans living in historically German territory, gain lands for expansion under the doctrine of Lebensraum, and exclude those deemed either Community Aliens or "inferior" races (Untermenschen).

Nazi human experimentation was a series of medical experiments on prisoners by Nazi Germany in its concentration camps mainly between 1942 and 1945. There were 15,754 documented victims, of various nationalities and ages, although the true number is believed to be more. About a quarter of documented victims were killed and survivors generally experienced severe permanent injuries.

At Auschwitz and other camps, under the direction of Eduard Wirths, selected inmates were subjected to various experiments that were designed to help German military personnel in combat situations, develop new weapons, aid in the recovery of military personnel who had been injured, and to advance Nazi racial ideology and eugenics, including the twin experiments of Josef Mengele. Aribert Heim conducted similar medical experiments at Mauthausen.

Ernst Heinrich Philipp August Haeckel (/ˈhɛkəl/; German: [ɛʁnst ˈhɛkl̩]; 16 February 1834 – 9 August 1919) was a German zoologist, naturalist, eugenicist, philosopher, physician, professor, marine biologist and artist. He discovered, described and named thousands of new species, mapped a genealogical tree relating all life forms and coined many terms in biology, including ecology, phylum, phylogeny, ontogeny, and Protista. Haeckel promoted and popularised Charles Darwin's work in Germany and developed the disproven but influential recapitulation theory ("ontogeny recapitulates phylogeny"), wrongly claiming that an individual organism's biological development, or ontogeny, parallels and summarizes its species' evolutionary development, or phylogeny, using incorrectly drawn images of human embryonic development. Whether they were intentionally falsified, or drawn poorly by accident is a matter of debate.

The published artwork of Haeckel includes over 100 detailed, multi-colour illustrations of animals and sea creatures, collected in his Kunstformen der Natur ("Art Forms of Nature"), a book which would go on to influence the Art Nouveau artistic movement. As a philosopher, Ernst Haeckel wrote Die Welträthsel (1895–1899; in English: The Riddles of the Universe, 1900), the genesis for the term "world riddle" (Welträtsel); and Freedom in Science and Teaching to support teaching evolution.

Sir William Matthew Flinders Petrie FRS FBA ((1853-06-03)3 June 1853 – (1942-07-29)29 July 1942), commonly known as simply Sir Flinders Petrie, was an English Egyptologist and a pioneer of systematic methodology in archaeology and the preservation of artefacts. He held the first chair of Egyptology in the United Kingdom, and excavated many of the most important archaeological sites in Egypt in conjunction with his Irish-born wife, Hilda Urlin. Some consider his most famous discovery to be that of the Merneptah Stele, an opinion with which Petrie himself concurred. Undoubtedly at least as important is his 1905 discovery and correct identification of the character of the Proto-Sinaitic script, the ancestor of almost all alphabetic scripts.

Petrie developed the system of dating layers based on pottery and ceramic findings. Petrie has been denounced for his pro-eugenics views; he was a dedicated believer in the superiority of the Northern peoples over the Latinate and Southern peoples.

Social degeneration was a widely influential concept at the interface of the social and biological sciences in the 18th and 19th centuries. During the 18th century, scientific thinkers including Georges-Louis Leclerc, Comte de Buffon, Johann Friedrich Blumenbach, and Immanuel Kant argued that humans shared a common origin but had degenerated over time due to differences in climate. This theory provided an explanation of where humans came from and why some people appeared differently from others. In contrast, degenerationists in the 19th century feared that civilization might be in decline and that the causes of decline lay in biological change. These ideas derived from pre-scientific concepts of heredity ("hereditary taint") with Lamarckian emphasis on biological development through purpose and habit. Degeneration concepts were often associated with authoritarian political attitudes, including militarism and scientific racism, and a preoccupation with eugenics. The theory originated in racial concepts of ethnicity, recorded in the writings of such medical scientists as Johann Blumenbach and Robert Knox. From the 1850s, it became influential in psychiatry through the writings of Bénédict Morel, and in criminology with Cesare Lombroso. By the 1890s, in the work of Max Nordau and others, degeneration became a more general concept in social criticism. It also fed into the ideology of ethnic nationalism, attracting, among others, Maurice Barrès, Charles Maurras and the Action Française. Alexis Carrel, a French Nobel Laureate in Medicine, cited national degeneration as a rationale for a eugenics programme in collaborationist Vichy France.

The meaning of degeneration was poorly defined, but can be described as an organism's change from a more complex to a simpler, less differentiated form, and is associated with 19th-century conceptions of biological devolution. In scientific usage, the term was reserved for changes occurring at a histological level – i.e. in body tissues. Although rejected by Charles Darwin, the theory's application to the social sciences was supported by some evolutionary biologists, most notably Ernst Haeckel and Ray Lankester. As the 19th century wore on, the increasing emphasis on degeneration reflected an anxious pessimism about the resilience of European civilization and its possible decline and collapse.

Superhumans are humans, humanoids or other beings with abilities and other qualities that exceed those naturally found in humans. These qualities may be acquired through natural ability, self-actualization or technological aids. The related concept of a super race refers to an entire category of beings with the same or varying superhuman characteristics, created from present-day human beings by deploying various means such as eugenics, euthenics, genetic engineering, nanotechnology, and/or brain–computer interfacing to accelerate the process of human evolution.

Throughout history, the discussion of superhuman traits and the idea of the ideal human in physical, mental, or spiritual form has influenced politics, policy, philosophy, science and various social movements, as well as featuring prominently in culture. Groups advocating the deliberate pursuit of superhuman qualities for philosophical, political, or moral reasons are sometimes referred to as superhumanist.
