Nazi Germany used six extermination camps, also called death camps, or killing centers, in Central Europe during World War II to systematically murder over 2.7 million people – mostly Jews – in the Holocaust. The victims of death camps were primarily murdered by gassing, either in permanent installations constructed for this specific purpose, or by means of gas vans. The six extermination camps were Chełmno, Belzec, Sobibor, Treblinka, Majdanek and Auschwitz-Birkenau. Extermination through labour was also used at the Auschwitz and Majdanek death camps. Millions were also murdered in concentration camps, in the Aktion T4, or directly on site.
A gas van or gas wagon was a truck re-equipped as a mobile gas chamber. During World War II and the Holocaust, Nazi Germany developed and used gas vans on a large scale to kill inmates of asylums, Poles, Romani people, Jews, and prisoners in occupied Poland, Belarus, Yugoslavia, the Soviet Union, and other regions of German-occupied Europe. One case of gas vans used by Soviet NKVD during the Great Purge was documented.
Aktion T4 was a campaign of mass murder by involuntary euthanasia in Nazi Germany. The term was first used in post-war trials against doctors who had been involved in the killings. The name T4 is an abbreviation of Tiergartenstraße 4, a street address of the Chancellery department set up in early 1940, in the Berlin borough of Tiergarten, which recruited and paid personnel associated with Aktion T4. Certain German physicians were authorised to select patients "deemed incurably sick, after most critical medical examination" and then administer to them a "mercy death". In October 1939, Adolf Hitler signed a "euthanasia note", backdated to 1 September 1939, which authorised his physician Karl Brandt and Reichsleiter Philipp Bouhler to begin the killing.
The Romani Holocaust or the Romani genocide was the planned effort by Nazi Germany and its World War II allies and collaborators to commit ethnic cleansing and eventually genocide against European Roma and Sinti peoples during the Holocaust era.
The term racial hygiene was used to describe an approach to eugenics in the early 20th century, which found its most extensive implementation in Nazi Germany. It was marked by efforts to avoid miscegenation, analogous to an animal breeder seeking purebred animals. This was often motivated by the belief in the existence of a racial hierarchy and the related fear that "lower races" would "contaminate" a "higher" one. As with most eugenicists at the time, racial hygienists believed that the lack of eugenics would lead to rapid social degeneration, the decline of civilization by the spread of inferior characteristics.
Viktor Hermann Brack was a member of the Schutzstaffel (SS) and a convicted Nazi war criminal and one of the prominent organisers of the euthanasia programme Aktion T4; this Nazi initiative resulted in the systematic murder of 275,000 to 300,000 disabled people. He held various positions of responsibility in Hitler's Chancellery in Berlin. Following his role in the T4 programme, Brack was one of the men identified as responsible for the gassing of Jews in extermination camps, having conferred with Odilo Globočnik about its use in the practical implementation of the Final Solution. Brack was sentenced to death in 1947 in the Doctors' Trial and executed by hanging in 1948.
Christian Wirth was a German SS officer and leading Holocaust perpetrator who was one of the primary architects of the program to exterminate the Jewish people of Poland, known as Operation Reinhard. His nicknames included Christian the Cruel, Stuka, and The Wild Christian due to the extremity of his behaviour among the SS and Trawniki guards and to the camp inmates and victims.
The phrase "life unworthy of life" was a Nazi designation for the segments of the populace which, according to the Nazi regime, had no right to live. Those individuals were targeted to be murdered by the state ("euthanized"), usually through the compulsion or deception of their caretakers. The term included people with serious medical problems and those considered grossly inferior according to the racial policy of Nazi Germany. This concept formed an important component of the ideology of Nazism and eventually helped lead to the Holocaust. It is similar to but more restrictive than the concept of Untermensch, subhumans, as not all "subhumans" were considered unworthy of life.
Victims of the Past is a Nazi propaganda film made in 1937, directed by Gernot Bock-Stieber and Kurt Botner.
The Hadamar killing centre was a killing facility involved in the Nazi involuntary euthanasia programme known as Aktion T4. It was housed within a psychiatric hospital located in the German town of Hadamar, near Limburg in Hessen.
Fritz Gottlieb Karl Lenz was a German geneticist, member of the Nazi Party, and influential specialist in eugenics in Nazi Germany.
Robert Ritter was a German racial scientist doctor of psychology and medicine, with a background in child psychiatry and the biology of criminality. In 1936, Ritter was appointed head of the Racial Hygiene and Demographic Biology Research Unit of Nazi Germany's Criminal Police, to establish the genealogical histories of the German "Gypsies", both Roma and Sinti, and became the "architect of the experiments Roma and Sinti were subjected to." His pseudo-scientific "research" in classifying these populations of Germany aided the Nazi government in their systematic persecution toward a goal of "racial purity".
Muselmann was a term used amongst prisoners of German Nazi concentration camps during the Holocaust of World War II to refer to those suffering from a combination of starvation and exhaustion, as well as those who were resigned to their impending death. The Muselmann prisoners exhibited severe emaciation and physical weakness, an apathetic listlessness regarding their own fate, and unresponsiveness to their surroundings owing to their barbaric treatment.
Nazi eugenics refers to the social policies of eugenics in Nazi Germany, composed of various ideas about genetics. The racial ideology of Nazism placed the biological improvement of the German people by selective breeding of "Nordic" or "Aryan" traits at its center. These policies were used to justify the involuntary sterilization and mass-murder of those deemed "undesirable".
Law for the Prevention of Genetically Diseased Offspring or "Sterilisation Law" was a statute in Nazi Germany enacted on July 14, 1933, which allowed the compulsory sterilisation of any citizen who in the opinion of a "Genetic Health Court" suffered from a list of alleged genetic disorders – many of which were not, in fact, genetic. The elaborate interpretive commentary on the law was written by three dominant figures in the racial hygiene movement: Ernst Rüdin, Arthur Gütt and the lawyer Falk Ruttke.
Holocaust victims were people targeted by the government of Nazi Germany based on their ethnicity, religion, political beliefs, and/or sexual orientation. The institutionalized practice by the Nazis of singling out and persecuting people resulted in the Holocaust, which began with legalized social discrimination against specific groups, involuntary hospitalization, euthanasia, and forced sterilization of persons considered physically or mentally unfit for society. The vast majority of the Nazi regime's victims were Jews, Sinti-Roma peoples, and Slavs but victims also encompassed people identified as social outsiders in the Nazi worldview, such as homosexuals, and political enemies. Nazi persecution escalated during World War II and included: non-judicial incarceration, confiscation of property, forced labor, sexual slavery, death through overwork, human experimentation, undernourishment, and execution through a variety of methods. For specified groups like the Jews, genocide was the Nazis' primary goal.
Alles Leben ist Kampf is a Nazi propaganda film produced in 1937, directed by Herbert Gerdes, and W. Hüttig.
Child Euthanasia was the name given to the organized killing of severely mentally and physically disabled children and young people up to 16 years old during the Nazi era in over 30 so-called special children's wards. At least 5,000 children were victims of the program, which was a precursor to the subsequent murder of children in the concentration camps.
The ideology of the Schutzstaffel, a paramilitary force and an instrument of terror of the Nazi Party in Nazi Germany, emphasized a racist vision of "racial purity", primarily based on antisemitism and loyalty to Adolf Hitler and Nazi Germany.
During the Second World War, the Roman Catholic Church protested against Aktion T4, the Nazi "involuntary euthanasia" programme under which the mentally ill, physically deformed, and incurably sick were murdered. The protests formed one of the most significant public acts of Catholic resistance to Nazism undertaken within Germany. The "euthanasia" programme began in 1939, and ultimately resulted in the murder of more than 70,000 people who were deemed senile, mentally handicapped, mentally ill, epileptics, cripples, children with Down's Syndrome, or people with similar afflictions. The murders involved interference in Church welfare institutions, and awareness of the murderous programme became widespread. Church leaders who opposed it – chiefly the Catholic Bishop Clemens August von Galen of Münster and Protestant Bishop Theophil Wurm – were therefore able to rouse widespread public opposition.
