In 1933, when Adolf Hitler assumed power in the German government, the usage of "Nazi" diminished in Germany, although Austrian anti-Nazis continued to use the term,[18] and the use of "Nazi Germany" and "Nazi regime" was popularised by anti-Nazis and German exiles abroad. Thereafter, the term spread into other languages and eventually was brought back to Germany after World War II.[22] In English, the term is not considered slang, and has such derivatives as Nazism and denazification.

In the first months of Hitler's chancellorship, the Nazis instituted a policy of "coordination"—the alignment of individuals and institutions with Nazi goals. Culture, the economy, education, and law all came under Nazi control. The Nazi regime also attempted to "coordinate" the German churches and, although not entirely successful, won support from a majority of Catholic and Protestant clergymen.

In March 1941, Himmler visited Auschwitz and commanded its enlargement to hold 30,000 prisoners. The location of the camp, practically in the center of German-occupied Europe, and its convenient transportation connections and proximity to rail lines was the main thinking behind the Nazi plan to enlarge Auschwitz and begin deporting people here from all over Europe.
The term was in use before the rise of the party as a colloquial and derogatory word for a backward peasant, an awkward and clumsy person. It derived from Ignaz, a shortened version of Ignatius,[20][21] which was a common name in the Nazis' home region of Bavaria. Opponents seized on this, and the long-existing Sozi, to attach a dismissive nickname to the National Socialists.[21][22]
In March 1933, the Enabling Act, an amendment to the Weimar Constitution, passed in the Reichstag by a vote of 444 to 94.[17] This amendment allowed Hitler and his cabinet to pass laws—even laws that violated the constitution—without the consent of the president or the Reichstag.[18] As the bill required a two-thirds majority to pass, the Nazis used intimidation tactics as well as the provisions of the Reichstag Fire Decree to keep several Social Democratic deputies from attending, and the Communists had already been banned.[19][20] On 10 May, the government seized the assets of the Social Democrats, and they were banned on 22 June.[21] On 21 June, the SA raided the offices of the German National People's Party – their former coalition partners – and they disbanded on 29 June. The remaining major political parties followed suit. On 14 July 1933 Germany became a one-party state with the passage of a law decreeing the NSDAP to be the sole legal party in Germany. The founding of new parties was also made illegal, and all remaining political parties which had not already been dissolved were banned.[22] The Enabling Act would subsequently serve as the legal foundation for the dictatorship the NSDAP established.[23] Further elections in November 1933, 1936, and 1938 were Nazi-controlled, with only members of the NSDAP and a small number of independents elected.[24]

On 4 September 2003, despite a protest from the museum, three Israeli Air Force F-15 Eagles performed a fly-over of Auschwitz II-Birkenau during a ceremony at the camp below. All three pilots were descendants of Holocaust survivors, including the man who led the flight, Major-General Amir Eshel.[298] On 27 January 2015, some 300 Auschwitz survivors gathered with world leaders under a giant tent at the entrance to Auschwitz II to commemorate the 70th anniversary of the camp's liberation.[299][i]
I worked out pretty quickly certain survival tricks. That if the guards called us to line up in front of the barracks, I should hide or sneak into another barracks. The safest place I could find to hide was in the yard near the bathrooms where all the dead bodies were brought and piled up … I would get on the pile, lie down next to the dead bodies and pretend I was one of them.
The gas chambers worked to their fullest capacity from April to July 1944, during the massacre of Hungary's Jews. Hungary was an ally of Germany during the war, but it had resisted turning over its Jews until Germany invaded that March.[178] A rail spur leading to crematoria II and III in Auschwitz II was completed that May, and a new ramp was built between sectors BI and BII to deliver the victims closer to the gas chambers.[179] On 29 April the first 1,800 Hungarian Jews arrived at the camp;[179] from 14 May until early July 1944, 437,000 Hungarian Jews, half the pre-war population, were deported to Auschwitz, at a rate of 12,000 a day for a considerable part of that period.[105] The crematoria had to be overhauled. Crematoria II and III were given new elevators leading from the stoves to the gas chambers, new grates were fitted, and several of the dressing rooms and gas chambers were painted. Cremation pits were dug behind crematorium V.[179] The last mass transports to arrive in Auschwitz were 60,000–70,000 Jews from the Łódź Ghetto, some 2,000 from Theresienstadt, and 8,000 from Slovakia.[167][180] The last selection took place on 30 October 1944.[163] Crematorium IV was demolished after the Sonderkommando revolt on 7 October 1944. The SS blew up crematorium V on 14 January 1945, and crematoria II and III on 20 January.[181]
In June 1945 the Soviet authorities took over Auschwitz I and converted it into a POW camp for German prisoners. The hospital had to move beyond the camp perimeter into former administrative buildings, where it functioned until October 1945.[254] Many of the barracks at Birkenau were taken apart by civilians, who used the materials to rebuild their own homes, which had been levelled out in the construction of Auschwitz II. The poorest residents sifted the crematoria ashes in search of nuggets from melted gold, before warning shots were fired.[255] The POW camp for German prisoners of war was used until 1947 by the Soviet NKVD (People's Commissariat for Internal Affairs).[256] The NKVD and its Polish counterpart, the MBP, used the Auschwitz Neu-Dachs sub-camp at Jaworzno to the north of Oświęcim as a concentration camp from 1945 to 1956.[257] The Soviets dismantled and exported the IG Farben factories to the USSR.[258] Meanwhile, Soviet and Polish investigators worked to document the war crimes of the SS.[259] After the site became a museum in 1947, exhumation work lasted for more than a decade.[185]
On a nearby table sat the second horn part to Tchaikovsky’s Capriccio Italien (Op. 45), which had been played by the death camp’s orchestra. Ms. Jastrzebiowska would preserve the page as it was, she said, and keep the smudges showing that the pages had been turned. “The objects must show their own history,” said Jolanta Banas-Maciaszczyk, 36, the leader of the preservation department.

However, it was the effects of the Great Depression in Germany that brought the Nazi Party to its first real nationwide importance. The rapid rise in unemployment in 1929–30 provided millions of jobless and dissatisfied voters whom the Nazi Party exploited to its advantage. From 1929 to 1932 the party vastly increased its membership and voting strength; its vote in elections to the Reichstag (the German Parliament) increased from 800,000 votes in 1928 to about 14,000,000 votes in July 1932, and it thus emerged as the largest voting bloc in the Reichstag, with 230 members (38 percent of the total vote). By then big-business circles had begun to finance the Nazi electoral campaigns, and swelling bands of SA toughs increasingly dominated the street fighting with the communists that accompanied such campaigns.
From its rise to power in 1933, the Nazi regime built a series of incarceration sites to imprison and eliminate so-called "enemies of the state." Most prisoners in the early concentration camps were German Communists, Socialists, Social Democrats, Roma (Gypsies), Jehovah's Witnesses, homosexuals, and persons accused of "asocial" or socially deviant behavior. Some of these facilities were called “concentration camps” because those imprisoned there were physically “concentrated” in one location.
With Hitler's approval, Himmler intended that the new society of the Nazi regime should destigmatise illegitimate births, particularly of children fathered by members of the SS, who were vetted for racial purity.[385] His hope was that each SS family would have between four and six children.[385] The Lebensborn (Fountain of Life) association, founded by Himmler in 1935, created a series of maternity homes to accommodate single mothers during their pregnancies.[386] Both parents were examined for racial suitability before acceptance.[386] The resulting children were often adopted into SS families.[386] The homes were also made available to the wives of SS and NSDAP members, who quickly filled over half the available spots.[387]
The process of denazification, which was initiated by the Allies as a way to remove Nazi Party members was only partially successful, as the need for experts in such fields as medicine and engineering was too great. However, expression of Nazi views was frowned upon, and those who expressed such views were frequently dismissed from their jobs.[495] From the immediate post-war period through the 1950s, people avoided talking about the Nazi regime or their own wartime experiences. While virtually every family suffered losses during the war has a story to tell, Germans kept quiet about their experiences and felt a sense of communal guilt, even if they were not directly involved in war crimes.[496]

Last, and perhaps most ominously for our comparisons with the Holocaust, the camps can be the first step toward darker developments, as some have already argued. These “concentration camps” will not lead to gas chambers, but their existence may well lead to the erosion of respect for human rights, the rule of law and government accountability that characterized the Third Reich. Unless, of course, the children are all actors.
Otto and Edith Frank planned to go into hiding with the children on 16 July 1942, but when Margot received a call-up notice from the Zentralstelle für jüdische Auswanderung (Central Office for Jewish Emigration) on 5 July, ordering her to report for relocation to a work camp, they were forced to move the plan ten days forward.[20] Shortly before going into hiding, Anne gave her friend and neighbour Toosje Kupers a book, a tea set, a tin of marbles, and the family cat for safekeeping. As the Associated Press reports: "'I'm worried about my marbles, because I'm scared they might fall into the wrong hands,' Kupers said Anne told her. 'Could you keep them for me for a little while?'"[21]
Today, at the beginning of the twenty-first century, the diary has not lost its power: in 2002, Habimah staged the play for the sixth time in Israel, an average of once per decade. In March 2002, Carol Ann Lee’s biography of Otto Frank, The Hidden Life of Otto Frank, had the Netherlands in an uproar. She places responsibility for the discovery of the attic’s inhabitants on Anton (Tony) Ahlers, a sworn antisemite and a member of the Dutch Nazi party who systematically informed on Jews. Ahlers was Frank’s business partner and knew that his spice company had done business with the Wehrmacht at the beginning of the war. Frank evidently paid Ahlers hush money even before his family entered the attic. Afterwards, he paid him not to reveal to the Dutch government that he had done business with the Wehrmacht, and apparently continued to pay him off until his death in 1980. Following the public furor, which spread to the United States, The Netherlands State Institute for War Documentation, the main organization that researches Anne Frank’s legacy today, announced that it would investigate Lee’s claims and soon publish its findings. Lee’s biography turns Anne’s father, the man who influenced her more than anyone and won her total admiration, into a man of flesh and blood devoid of the saintly image that had previously clung to him. It also placed the issues of informing and collaboration in the Netherlands and in Europe back on the public agenda, along with the question of the relationship to the Jewish citizens of those countries and their fate. Once more, Anne’s image hovers over the controversy, with its dark eyes and penetrating gaze, its hopes for a new world and faith in humankind.
When your relatives die, there’s usually a place you can go to pay your respects, like a cemetery with a grave where you can lay a stone and talk to them. The only place I have is Auschwitz and going back there for the first time will be the first and last chance I have to be able to return to the people I loved who I lost there and in other concentration camps.
The process of Anne’s transformation into a universal teenager continued with the Americanization of her diary. “These are the thoughts and expression of a young girl living under extraordinary conditions, and for this reason her diary tell us much about ourselves and about our own children. And for this reason, too, I felt how close we all are to Anne’s experience, how very much involved we are in her short life and in the entire world,” Eleanor Roosevelt wrote in her introduction. Were Americans living in 1952 really close to Anne’s experiences? Were they really capable of understanding her and becoming involved in her life? Perhaps they were, though not as a Jewish girl hiding from the Nazis, but as an “Everygirl.” In her foreword, Eleanor Roosevelt makes no reference to Jews or to Anne’s Jewishness, nor to the way her brief life ended, nor to the Holocaust, thus distancing the diary even more from Jews and from the Holocaust by referring to human problems in general.
The Franks had to be careful not be caught by the Germans. They covered all the windows with thick curtains. During the day they had to be extra quiet. They whispered when they talked and went barefoot so they could walk softly. At night, when the people working in the business below went home, they could relax a bit, but they still had to be very careful. 

A new type of court, the Volksgerichtshof ("People's Court"), was established in 1934 to deal with political cases.[209] This court handed out over 5,000 death sentences until its dissolution in 1945.[210] The death penalty could be issued for offences such as being a communist, printing seditious leaflets, or even making jokes about Hitler or other officials.[211] The Gestapo was in charge of investigative policing to enforce National Socialist ideology as they located and confined political offenders, Jews, and others deemed undesirable.[212] Political offenders who were released from prison were often immediately re-arrested by the Gestapo and confined in a concentration camp.[213]

After Germany's annexation of Austria in March 1938, the Nazis arrested German and Austrian Jews and imprisoned them in the Dachau, Buchenwald, and Sachsenhausen concentration camps, all located in Germany. Following the violent Kristallnacht ("Night of Broken Glass") pogroms in November 1938, the Nazis conducted mass arrests of adult male Jews and incarcerated them in camps for brief periods.
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]
