The first German concentration camps were established in 1933 for the confinement of opponents of the Nazi Party—Communists and Social Democrats. Political opposition soon was enlarged to include minority groups, chiefly Jews, but by the end of World War II many Roma, homosexuals, and anti-Nazi civilians from the occupied territories had also been liquidated. After the outbreak of World War II the camp inmates were used as a supplementary labour supply, and such camps mushroomed throughout Europe. Inmates were required to work for their wages in food; those unable to work usually died of starvation, and those who did not starve often died of overwork. The most shocking extension of this system was the establishment after 1940 of extermination centres, or “death camps.” They were located primarily in Poland, which Adolf Hitler had selected as the setting for his “final solution” to the “Jewish problem.” The most notorious were Auschwitz, Majdanek, and Treblinka. (See extermination camp.) At some camps, notably Buchenwald, medical experimentation was conducted. New toxins and antitoxins were tried out, new surgical techniques devised, and studies made of the effects of artificially induced diseases, all by experimenting on living human beings.
In every camp, Allied soldiers encountered appalling scenes. Bergen-Belsen was liberated by British forces on 15 April 1945. It had become exceptionally overcrowded after the arrival of survivors of the death marches. Thousands of unburied bodies lay strewn around the camp, while in the barracks some 60,000 starving and mortally ill people were packed together without food or water. The mortality rate amongst those suffering from typhus was over 60 per cent.
Nazi Germany is the common English name for Germany between 1933 and 1945, when Adolf Hitler and his Nazi Party (NSDAP) controlled the country through a dictatorship. Under Hitler's rule, Germany was transformed into a totalitarian state that controlled nearly all aspects of life via the Gleichschaltung legal process. The official name of the state was Deutsches Reich (German Reich) until 1943 and Großdeutsches Reich (Greater German Reich) from 1943 to 1945. Nazi Germany is also known as the Third Reich (Drittes Reich), meaning "Third Realm" or "Third Empire", the first two being the Holy Roman Empire (800–1806) and the German Empire (1871–1918). The Nazi regime ended after the Allies defeated Germany in May 1945, ending World War II in Europe.
Lt.-Col. Anatoly Shapiro, Ukrainian Jew, commanded the Red Army’s 1085th ‘Tarnopol’ Rifle Regiment that liberated Auschwitz on January 27, 1945. The soldiers found about 650 corpses inside the barracks and near them — mostly women who died of exhaustion or were shot by the SS the night before. Altogether, the Soviet troops found at least 1,200 emaciated survivors in Auschwitz and another 5,800 at Birkenau. They fed them but most could not eat because they were too malnourished. Ultimately, another soldier said the Red Army managed to save 2,819 inmates in Red Army Military Hospital 2962.
Adolf Hitler, the party's leader since 1921, was appointed Chancellor of Germany by President Paul von Hindenburg on 30 January 1933. Hitler rapidly established a totalitarian regime[12][13][14][15] known as the Third Reich. Following the defeat of the Third Reich at the conclusion of World War II in Europe, the party was "declared to be illegal" by the Allied powers,[16] who carried out denazification in the years after the war.
Sessions’s characterization falls into a nether region between truth and falsehood. Perhaps his is the best comment to begin with precisely because it is a half-truth. Yes, after 1941, concentration camps held Jews to prevent them from leaving Germany — but also to consolidate them for extermination. However, for more than eight years earlier, the camps generally were used for the opposite purpose: to force Jews to emigrate from Germany by making life intolerable, in part by separating men from their families. This is precisely the kind of important historical nuance lost in the hysteria surrounding Trump’s callous immigration policy. There are valuable comparisons to be made, but they must be historically informed.
The property is of adequate size to ensure the complete representation of the features and processes that convey its significance. Potential threats to the integrity of the property include the difficulty in preserving the memory of the events and their significance to humanity. In the physical sphere, significant potential threats include natural decay of the former camps’ fabric; environmental factors, including the risk of flooding and rising groundwater level; changes in the surroundings of the former camps; and intensive visitor traffic.
^ The Cambridge Companion to Tacitus, p. 294. A. J. Woodman - 2009 "The white race was defined as beautiful, honourable and destined to rule; within it the Aryans are 'cette illustre famille humaine, la plus noble'." Originally a linguistic term synonymous with Indo-European, 'Aryan' became, not least because of the Essai, the designation of a race, which Gobineau specified was 'la race germanique'

In the Soviet Union by 1922 there were 23 concentration camps for the incarceration of persons accused of political offenses as well as criminal offenses. Many corrective labour camps were established in northern Russia and Siberia, especially during the First Five-Year Plan, 1928–32, when millions of rich peasants were driven from their farms under the collectivization program. The Stalinist purges of 1936–38 brought additional millions into the camps—said to be essentially institutions of slavery.

I was taken into protective custody in connection with the murder of the German attaché in Paris, Ernst vom Rath, by the seventeen-year-old Polish subject, Grynszpan, who had been expelled from Germany first and then had been ordered to leave France. I do not want to justify this political murder in any way, but I can understand it as the act of a hopelessly desperate person.

It had become exceptionally overcrowded after the arrival of survivors of the death marches.

During the next two months, some fifty thousand people were arrested on this basis, in what turned into a “frenzy” of political purges and score-settling. In the legal murk of the early Nazi regime, it was unclear who had the power to make such arrests, and so it was claimed by everyone: national, state, and local officials, police and civilians, Party leaders. “Everybody is arresting everybody,” a Nazi official complained in the summer of 1933. “Everybody threatens everybody with Dachau.” As this suggests, it was already clear that the most notorious and frightening destination for political detainees was the concentration camp built by Himmler at Dachau, in Bavaria. The prisoners were originally housed in an old munitions factory, but soon Himmler constructed a “model camp,” the architecture and organization of which provided the pattern for most of the later K.L. The camp was guarded not by police but by members of the S.S.—a Nazi Party entity rather than a state force.

Entrance is free in general, but visitor numbers are regulated by a ticket system. Be aware that because of the large numbers of visitors, entry to the Auschwitz I site is done exclusively on a paid guided (yet unfortunately rather rushed) tour between 10:00 to 15:00 during the period from 1 April to 31 October. You can visit the site on your own (which is highly recommended, as visitors can go at their own pace, see what they want to see, and have a much more meaningful experience) if you arrive before 10:00 (better 8:00-9:00) or after 15:00 (depending on the season and day of week). This is recommended if you're staying nearby in Katowice or Kraków and don't have your own car, with some trains from Kraków and Katowice Główny arriving between 8-10. Guided tours cost 45PLN (discounted price for students up to 24 years of age is 30PLN). Students with an ISIC card are granted free entrance during tour hours. If you're a small group (~4 or less), it's not too hard to buy tickets on site (but depending on the season, you might have to wait depending on availability), but larger groups should book tickets in advance.
The Germans isolated all the camps and sub-camps from the outside world and surrounded them with barbed wire fencing. All contact with the outside world was forbidden. However, the area administered by the commandant and patrolled by the SS camp garrison went beyond the grounds enclosed by barbed wire. It included an additional area of approximately 40 square kilometers (the so-called “Interessengebiet” - the interest zone), which lay around the Auschwitz I and Auschwitz II-Birkenau camps.
Racism and antisemitism were basic tenets of the NSDAP and the Nazi regime. Nazi Germany's racial policy was based on their belief in the existence of a superior master race. The Nazis postulated the existence of a racial conflict between the Aryan master race and inferior races, particularly Jews, who were viewed as a mixed race that had infiltrated society and were responsible for the exploitation and repression of the Aryan race.[298]

The first mass transport to Auschwitz I, which included Catholic prisoners, suspected members of the Polish resistance, and 20 Jews, arrived on 14 June 1940 from prison in Tarnów, Poland. They were interned in the former building of the Polish Tobacco Monopoly, adjacent to the site, until the camp was ready.[24] By the end of 1940, the SS had confiscated land around the camp to create a 40-square-kilometre (15 sq mi) "zone of interest" surrounded by a double ring of electrified barbed wire fences and watchtowers.[25] The inmate population grew quickly as the camp absorbed Poland's intelligentsia and dissidents. By March 1941, 10,900 were imprisoned there, most of them Poles.[22]

A parallel system operated later at Birkenau in 1942-43, except that for the majority the 'showers' proved to be gas chambers. Only about 10 percent of Jewish transports were registered, disinfected, shaven and showered in the 'central sauna' before being assigned barracks. In May 1944, a spur line was built right into the camp to accelerate and simplify the handling of the tens of thousands of Hungarian and other Jews deported in the spring and summer of 1944.
The line most often quoted from Frank’s diary—“In spite of everything, I still believe that people are really good at heart”—is often called “inspiring,” by which we mean that it flatters us. It makes us feel forgiven for those lapses of our civilization that allow for piles of murdered girls—and if those words came from a murdered girl, well, then, we must be absolved, because they must be true. That gift of grace and absolution from a murdered Jew (exactly the gift, it is worth noting, at the heart of Christianity) is what millions of people are so eager to find in Frank’s hiding place, in her writings, in her “legacy.” It is far more gratifying to believe that an innocent dead girl has offered us grace than to recognize the obvious: Frank wrote about people being “truly good at heart” three weeks before she met people who weren’t.
The lead editors of the Encyclopedia of Camps and Ghettos, 1933–1945 of the United States Holocaust Memorial Museum, Geoffrey Megargee and Martin Dean, cataloged some 42,500 Nazi ghettos and camps throughout Europe, spanning German-controlled areas from France to Russia and Germany itself, operating from 1933 to 1945. They estimate that 15 million to 20 million people died or were imprisoned in the sites.[36]
