Hitler quickly became the party's most active orator, appearing in public as a speaker 31 times within the first year after his self-discovery.[55] Crowds began to flock to hear his speeches.[56] Hitler always spoke about the same subjects: the Treaty of Versailles and the Jewish question.[48] This deliberate technique and effective publicising of the party contributed significantly to his early success,[48] about which a contemporary poster wrote: "Since Herr Hitler is a brilliant speaker, we can hold out the prospect of an extremely exciting evening".[57] Over the following months, the party continued to attract new members,[41] while remaining too small to have any real significance in German politics.[58] By the end of the year, party membership was recorded at 2,000,[56] many of whom Hitler and Röhm had brought into the party personally, or for whom Hitler's oratory had been their reason for joining.[59]
From 1942 onwards, Auschwitz became one of the greatest scenes of mass murder in recorded history. The vast majority of the camp's 1.1 million Jewish men, women, and children, deported from their homes across occupied Europe to Auschwitz, were sent immediately to their deaths in the Birkenau gas chambers upon arrival, usually transported into the camp by overcrowded cattle wagons. Their bodies were afterwards cremated in industrial furnaces in the crematoria. Those who were not killed in the gas chambers often died of disease, starvation, medical experiments, forced labor, or execution.

Nazism subscribed to theories of racial hierarchy and Social Darwinism, identifying the Germans as a part of what the Nazis regarded as an Aryan or Nordic master race.[3] It aimed to overcome social divisions and create a German homogeneous society based on racial purity which represented a people's community (Volksgemeinschaft). The Nazis aimed to unite all Germans living in historically German territory, as well as gain additional lands for German expansion under the doctrine of Lebensraum and exclude those who they deemed either community aliens or "inferior" races.
Hitler spoke of Nazism being indebted to the success of Fascism's rise to power in Italy.[125] In a private conversation in 1941, Hitler said that "the brown shirt would probably not have existed without the black shirt", the "brown shirt" referring to the Nazi militia and the "black shirt" referring to the Fascist militia.[125] He also said in regards to the 1920s: "If Mussolini had been outdistanced by Marxism, I don't know whether we could have succeeded in holding out. At that period National Socialism was a very fragile growth".[125]

When Hitler and the Nazis came to power in 1933, they instituted a series of measures aimed at persecuting Germany’s Jewish citizens. By late 1938, Jews were banned from most public places in Germany. During the war, the Nazis’ anti-Jewish campaigns increased in scale and ferocity. In the invasion and occupation of Poland, German troops shot thousands of Polish Jews, confined many to ghettoes where they starved to death and began sending others to death camps in various parts of Poland, where they were either killed immediately or forced into slave labor. In 1941, when Germany invaded the Soviet Union, Nazi death squads machine-gunned tens of thousands of Jews in the western regions of Soviet Russia.
The Nazis claimed that Bismarck was unable to complete German national unification because Jews had infiltrated the German parliament and they claimed that their abolition of parliament had ended this obstacle to unification.[73] Using the stab-in-the-back myth, the Nazis accused Jews—and other populations who it considered non-German—of possessing extra-national loyalties, thereby exacerbating German antisemitism about the Judenfrage (the Jewish Question), the far-right political canard which was popular when the ethnic Völkisch movement and its politics of Romantic nationalism for establishing a Großdeutschland was strong.[99][100]

I won’t be going back to Auschwitz again after this visit. So it’s my last chance to make sure this tragedy is not forgotten. I found out only about a week before I was due to leave that I will be one of two survivors who will be part of the US presidential delegation, headed by the secretary of the treasury, Jack Lew, and I feel very honoured, but it has much to do with the fact that many others who could go are ill and unable to travel.

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.”
The NSDAP briefly adopted the designation "Nazi"[when?] in an attempt to reappropriate the term, but it soon gave up this effort and generally avoided using the term while it was in power.[10][11] For example, in Hitler's book Mein Kampf, originally published in 1925, he never refers to himself as a "Nazi."[15] A compendium of conversations of Hitler from 1941 through 1944 entitled Hitler's Table Talk does not contain the word "Nazi" either.[16] In speeches by Hermann Göring, he never uses the term "Nazi."[17] Hitler Youth leader Melita Maschmann wrote a book about her experience entitled Account Rendered[18]. She did not refer to herself as a "Nazi," even though she was writing well after World War II. In 1933 581 members of the National Socialist Party answered interview questions put to them by Professor Theodore Abel from Columbia University. They similarly did not refer to themselves as "Nazis."[19] In each case, the authors refer to themselves as "National Socialists" and their movement as "National Socialism," but never as "Nazis."
The camps were liberated by the Allied forces between 1944 and 1945. The first major camp, Majdanek, was discovered by the advancing Soviets on July 23, 1944. Auschwitz was liberated, also by the Soviets, on January 27, 1945; Buchenwald by the Americans on April 11; Bergen-Belsen by the British on April 15; Dachau by the Americans on April 29; Ravensbrück by the Soviets on the same day; Mauthausen by the Americans on May 5; and Theresienstadt by the Soviets on May 8.[42] Treblinka, Sobibór, and Bełżec were never liberated, but were destroyed by the Nazis in 1943. Colonel William W. Quinn of the U.S. 7th Army said of Dachau: "There our troops found sights, sounds, and stenches horrible beyond belief, cruelties so enormous as to be incomprehensible to the normal mind."[43][44]
As the German economy developed, the country began to suffer labour shortages. The concentration camp population was used to fill this void. After the Anschluss, thousands of Austrian Jews recently forced out of employment, non-Jewish ‘asocials’ and opponents of the Nazis were rounded up and used as a freely available source of forced labour. Many of these would provide the much-needed human resources to produce weapons, vehicles and goods for the German war effort.
By plastering this sentence on Frank’s book jackets, publishers have implied that her posthumous fame represented the fulfillment of the writer’s dream. But when we consider the writer’s actual ambitions, it is obvious that her dreams were in fact destroyed—and it is equally obvious that the writer who would have emerged from Frank’s experience would not be anything like the writer Frank herself originally planned to become. Consider, if you will, the following imaginary obituary of a life unlived:

On 25 November 1947, the Auschwitz trial began in Kraków, when Poland's Supreme National Tribunal brought to court 40 former Auschwitz staff. The trial's defendants included commandant Arthur Liebehenschel, women's camp leader Maria Mandel, and camp leader Hans Aumeier. The trials ended on 22 December 1947, with 23 death sentences, 7 life sentences, and 9 prison sentences ranging from three to fifteen years. Hans Münch, an SS doctor who had several former prisoners testify on his behalf, was the only person to be acquitted.[268]

After September 1939, with the beginning of the Second World War, concentration camps became places where millions of ordinary people were enslaved as part of the war effort, often starved, tortured and killed.[21] During the war, new Nazi concentration camps for "undesirables" spread throughout the continent. According to statistics by the German Ministry of Justice, about 1,200 camps and subcamps were run in countries occupied by Nazi Germany,[22] while the Jewish Virtual Library estimates that the number of Nazi camps was closer to 15,000 in all of occupied Europe[23][24] and that many of these camps were run for a limited amount of time before they were closed.[23] Camps were being created near the centers of dense populations, often focusing on areas with large communities of Jews, Polish intelligentsia, Communists or Romani. Since millions of Jews lived in pre-war Poland, most camps were located in the area of the General Government in occupied Poland, for logistical reasons. The location also allowed the Nazis to quickly remove the German Jews from within Germany proper.
