During the German invasion of the Soviet Union the Nazis began the first mass killings of Jews. Between June and September 1941, the Einsatzgruppen supported by local collaborators murdered hundreds of thousands of Jews across Latvia, Lithuania, Estonia and the Soviet Union. Having observed the killings, Adolf Eichmann ordered a more efficient method of killing the Jews of Europe be developed.
A useful analogy requires that we move beyond a Google image search and truly interrogate history. If we do, we may arrive at the Camp de Rivesaltes, an ad hoc facility created from an empty military camp in southern France. Its first prisoners in 1938 were not Jews but Spanish refugees who had fought against Francisco Franco’s victorious fascists. They were fleeing inevitable persecution from the Spanish dictator. The goal of that temporary concentration camp was to prevent the further dispersion of the Spanish refugees and their settlement in France while a repatriation solution was found. It never was.
^ This was the result of either a club foot or osteomyelitis. Goebbels is commonly said to have had club foot (talipes equinovarus), a congenital condition. William L. Shirer, who worked in Berlin as a journalist in the 1930s and was acquainted with Goebbels, wrote in The Rise and Fall of the Third Reich (1960) that the deformity was caused by a childhood attack of osteomyelitis and a failed operation to correct it.
Upon his release Hitler quickly set about rebuilding his moribund party, vowing to achieve power only through legal political means thereafter. The Nazi Party’s membership grew from 25,000 in 1925 to about 180,000 in 1929. Its organizational system of gauleiters (“district leaders”) spread through Germany at this time, and the party began contesting municipal, state, and federal elections with increasing frequency.
Wilhelm Stapel, an antisemitic German intellectual, utilised Spengler's thesis on the cultural confrontation between Jews as whom Spengler described as a Magian people versus Europeans as a Faustian people.[117] Stapel described Jews as a landless nomadic people in pursuit of an international culture whereby they can integrate into Western civilisation.[117] As such, Stapel claims that Jews have been attracted to "international" versions of socialism, pacifism or capitalism because as a landless people the Jews have transgressed various national cultural boundaries.[117]

Fleeing Germans also torched a couple of dozen of the wooden barracks at Birkenau. Many of the camp buildings that were left largely intact were later taken apart by Poles desperate for shelter. Birkenau remains the starkest, most tangible, most haunting reminder of what Dwork says was the “greatest catastrophe Western civilization permitted, and endured.”
In July 1945, after the Red Cross confirmed the deaths of the Frank sisters, Miep Gies gave Otto Frank the diary and a bundle of loose notes that she had saved in the hope of returning them to Anne. Otto Frank later commented that he had not realized Anne had kept such an accurate and well-written record of their time in hiding. In his memoir, he described the painful process of reading the diary, recognizing the events described and recalling that he had already heard some of the more amusing episodes read aloud by his daughter. He saw for the first time the more private side of his daughter and those sections of the diary she had not discussed with anyone, noting, "For me it was a revelation ... I had no idea of the depth of her thoughts and feelings ... She had kept all these feelings to herself".[65] Moved by her repeated wish to be an author, he began to consider having it published.[66]
As the war continued, it became more difficult to find food for the group in hiding. Bep Voskuijl was nearly arrested bringing food back to the secret annex even though it was only enough food for two days. The German officer who stopped her followed her, forcing her to avoid the Prinsencgracht, which meant that the group in hiding had nothing to eat that day, which became more common as the days wore on.

In the decades since its liberation, Auschwitz has become a primary symbol of the Holocaust. Historian Timothy D. Snyder attributes this to the camp's high death toll and "unusual combination of an industrial camp complex and a killing facility", which left behind far more witnesses than single-purpose killing facilities such as Chełmno or Treblinka.[272] In 2005 the United Nations General Assembly designated 27 January, the date of the camp's liberation, as International Holocaust Remembrance Day.[273] Helmut Schmidt visited the site in November 1977, the first West German chancellor to do so, followed by his successor, Helmut Kohl, in November 1989.[274] In a written statement on the fiftieth anniversary of the liberation, Kohl described Auschwitz as the "darkest and most horrific chapter of German history".[275]
Auschwitz, the largest and arguably the most notorious of all the Nazi death camps, opened in the spring of 1940. Its first commandant was Rudolf Höss (1900-47), who previously had helped run the Sachsenhausen concentration camp in Oranienburg, Germany. Auschwitz was located on a former military base outside OÅ›wiÄ™cim, a town in southern Poland situated near Krakow, one of the country’s largest cities. During the camp’s construction, nearby factories were appropriated and all those living in the area were forcibly ejected from their homes, which were bulldozed by the Nazis.
Known as block 13 until 1941, block 11 of Auschwitz I was the prison within the prison, where violators of the numerous rules were punished. To extract information from them, guards would hold inmates' heads held against the stove, burning their faces and eyes. Some prisoners were made to spend the nights in standing cells. Measuring 1.5 m2 (16 sq ft), the cells held four men who could do nothing but stand, and who were forced the following day to work as usual.[137] In other cells, inmates were subjected to hanging with their hands behind their backs, thus dislocating their shoulder joints. In the basement were the "dark cells", which had only a 5 x 5 cm opening and a solid door. Prisoners placed in these cells gradually suffocated as they ran out of oxygen; sometimes the SS lit a candle in the cell to use up the oxygen more quickly.[138]
Jews, Gypsies (Roma), homosexuals, asocials, criminals, and prisoners of war were gathered, stuffed into cattle cars on trains, and sent to Auschwitz. When the trains stopped at Auschwitz II: Birkenau, the newly arrived were told to leave all their belongings on board and were then forced to disembark from the train and gather upon the railway platform, known as "the ramp."

As a result of the Holocaust, the term "concentration camp" carries many of the connotations of "extermination camp" and is sometimes used synonymously. Because of these ominous connotations, the term "concentration camp", originally itself a euphemism, has been replaced by newer terms such as internment camp, resettlement camp, detention facility, etc., regardless of the actual circumstances of the camp, which can vary a great deal.
