On 24 December 1941 the resistance groups representing the various prisoner factions met in block 45 and agreed to cooperate. Fleming writes that it has not been possible to track Pilecki's early intelligence from the camp. Pilecki compiled two reports after he escaped in April 1943; the second, Raport W, detailed his life in Auschwitz I and estimated that 1.5 million people, mostly Jews, had been killed.[204] On 1 July 1942, the Polish Fortnightly Review published a report describing Birkenau, writing that "prisoners call this supplementary camp 'Paradisal', presumably because there is only one road, leading to Paradise". Reporting that inmates were being killed "through excessive work, torture and medical means", it noted the gassing of the Soviet prisoners of war and Polish inmates in Auschwitz I in September 1941, the first gassing in the camp. It said: "It is estimated that the Oswiecim camp can accommodate fifteen thousand prisoners, but as they die on a mass scale there is always room for new arrivals."[205]

The Zyklon B was delivered by ambulance to the crematoria by a special SS bureau known as the Hygienic Institute.[104] The actual delivery of the gas to the victims was always handled by the SS, on the order of the supervising SS doctor.[174][175] After the doors were shut, SS men dumped in the Zyklon B pellets through vents in the roof or holes in the side of the chamber. The victims were dead within 20 minutes.[174] Despite the thick concrete walls, screaming and moaning from within could be heard outside. In one failed attempt to muffle the noise, two motorcycle engines were revved up to full throttle nearby, but the sound of yelling could still be heard over the engines.[176]
In 1957, Fria ord ("Free Words"), the magazine of the Swedish neofascist organization National League of Sweden published an article by Danish author and critic Harald Nielsen, who had previously written antisemitic articles about the Danish-Jewish author Georg Brandes.[93] Among other things, the article claimed that the diary had been written by Meyer Levin.[94]

The first experimental gassing took place in September 1941, when Lagerführer Karl Fritzsch, at the instruction of Rudolf Höss, killed a group of Soviet prisoners of war by throwing Zyklon B crystals into their basement cell in block 11 of Auschwitz I. A second group of 600 Soviet prisoners of war and around 250 sick Polish prisoners was gassed on 3–5 September.[29] The morgue was later converted to a gas chamber able to hold at least 700–800 people.[30] Zyklon B was dropped into the room through slits in the ceiling.[28] In the view of Filip Müller, one of the Sonderkommando who worked in crematorium I, tens of thousands of Jews were killed there from France, Holland, Slovakia, Upper Silesia, Yugoslavia, and from the Theresienstadt, Ciechanow, and Grodno ghettos.[31] The last inmates to be gassed in Auschwitz I, in December 1942, were 300–400 members of the Auschwitz II Sonderkommando, who had been forced to dig up that camp's mass graves, thought to hold 100,000 corpses, and burn the remains.[32]

A play by Frances Goodrich and Albert Hackett based upon the diary premiered in New York City on 5 October 1955, and later won a Pulitzer Prize for Drama. It was followed by the film The Diary of Anne Frank (1959), which was a critical and commercial success. Biographer Melissa Müller later wrote that the dramatization had "contributed greatly to the romanticizing, sentimentalizing and universalizing of Anne's story."[73] Over the years the popularity of the diary grew, and in many schools, particularly in the United States, it was included as part of the curriculum, introducing Anne Frank to new generations of readers.[74]
As the Russians closed in on Auschwitz, the Germans became desperate, destroying as much evidence of war crimes as they could, including records and property seized from prisoners, and forcing as many prisoners as they could on what became death marches. The day before the Russian Army liberated Auschwitz, Edith died there. On January 27 Otto was liberated and taken to Odessa and then France before being allowed to return to Amsterdam in June 1945.
Ever since the Auschwitz memorial and museum first opened to the public, in 1947, workers have repaired and rebuilt the place. The barbed wire that rings the camps must be continuously replaced as it rusts. In the 1950s, construction crews repairing the crumbling gas chamber at the main Auschwitz camp removed one of the original walls. Most recently, the staff has had to deal with crime and vandalism. This past December, the Arbeit Macht Frei sign was stolen by thieves, who intended to sell it to a collector. Although the sign was recovered, it was cut into three pieces and will need to be repaired.
By the time the Germans invaded Poland in September 1939, unleashing World War II, there were six concentration camps in the so-called Greater German Reich: Dachau (founded 1933), Sachsenhausen (1936), Buchenwald (1937), Flossenbürg in northeastern Bavaria near the 1937 Czech border (1938), Mauthausen, near Linz, Austria (1938), and Ravensbrück, the women's camp, established in Brandenburg Province, southeast of Berlin (1939), after the dissolution of Lichtenburg.
The NSDAP (Nazi Party) assumed power in 1933 in the aftermath and decline of the Weimar Republic. In response to the instability created by the Great Depression, the Nazis sought a Third Way managed economy that was neither capitalism nor communism. Nazi rule effectively ended on May 7, 1945, V-E Day (Victory in Europe Day), when the Nazis unconditionally surrendered to the Allied Powers, who took over Germany's administration until Germany could form its own democratic government.

Edith Frank died of starvation at Auschwitz in January 1945. Hermann van Pels died in the gas chambers at Auschwitz soon after his arrival there in 1944; his wife is believed to have likely died at the Theresienstadt concentration camp in what is now the Czech Republic in the spring of 1945. Peter van Pels died at the Mauthausen concentration camp in Austria in May 1945. Fritz Pfeffer died from illness in late December 1944 at the Neuengamme concentration camp in Germany. Anne Frank’s father, Otto, was the only member of the group to survive; he was liberated from Auschwitz by Soviet troops on January 27, 1945.

In 1976, Otto Frank took action against Heinz Roth of Frankfurt, who published pamphlets stating that the diary was "a forgery". The judge ruled that if Roth was to publish any further statements he would be subjected to a fine of 500,000 German marks and a six-month jail sentence. Roth appealed against the court's decision. He died in 1978, and after a year his appeal was rejected.[94]
Hitler expressed opposition to capitalism, regarding it as having Jewish origins and accusing capitalism of holding nations ransom to the interests of a parasitic cosmopolitan rentier class.[51] He also expressed opposition to communism and egalitarian forms of socialism, arguing that inequality and hierarchy are beneficial to the nation.[52] He believed that communism was invented by the Jews to weaken nations by promoting class struggle.[53] After his rise to power, Hitler took a pragmatic position on economics, accepting private property and allowing capitalist private enterprises to exist so long as they adhered to the goals of the Nazi state, but not tolerating enterprises that he saw as being opposed to the national interest.[37]
And it means deploying conservators to preserve an inventory that includes more than a ton of human hair; 110,000 shoes; 3,800 suitcases; 470 prostheses and orthopedic braces; more than 88 pounds of eyeglasses; hundreds of empty canisters of Zyklon B poison pellets; patented metal piping and showerheads for the gas chambers; hundreds of hairbrushes and toothbrushes; 379 striped uniforms; 246 prayer shawls; more than 12,000 pots and pans carried by Jews who believed that they were simply bound for resettlement; and some 750 feet of SS documents — hygiene records, telegrams, architectural blueprints and other evidence of the bureaucracy of genocide — as well as thousands of memoirs by survivors.
In January 1934, Germany signed a non-aggression pact with Poland.[73] In March 1939, Hitler demanded the return of the Free City of Danzig and the Polish Corridor, a strip of land that separated East Prussia from the rest of Germany. The British announced they would come to the aid of Poland if it was attacked. Hitler, believing the British would not actually take action, ordered an invasion plan should be readied for September 1939.[74] On 23 May, Hitler described to his generals his overall plan of not only seizing the Polish Corridor but greatly expanding German territory eastward at the expense of Poland. He expected this time they would be met by force.[75]

When the day of release came we were at first searched most carefully for any sort of written notes. Notes from our family—a short, well-watched exchange was allowed every week—had to be left behind. Then we were permitted to put on our civilian clothes, but how they looked! They had been disinfected under high steam pressure and had been wrapped in bundles. They looked like the outfits of tramps, all creased and out of shape. Soft felt hats had turned into cardboard-like monsters no longer usable, and even on our short trip back they could not be worn.
Nazism attempted to reconcile conservative, nationalist ideology with a socially radical doctrine. In so doing, it became a profoundly revolutionary movement—albeit a largely negative one. Rejecting rationalism, liberalism, democracy, the rule of law, human rights, and all movements of international cooperation and peace, it stressed instinct, the subordination of the individual to the state, and the necessity of blind and unswerving obedience to leaders appointed from above. It also emphasized the inequality of men and races and the right of the strong to rule the weak; sought to purge or suppress competing political, religious, and social institutions; advanced an ethic of hardness and ferocity; and partly destroyed class distinctions by drawing into the movement misfits and failures from all social classes. Although socialism was traditionally an internationalist creed, the radical wing of Nazism knew that a mass base existed for policies that were simultaneously anticapitalist and nationalist. However, after Hitler secured power, this radical strain was eliminated.
Between 1933 and the fall of Nazi Germany in 1945, more than 3.5 million Germans were forced to spend time in concentration camps and prisons for political reasons,[18][19][20] and approximately 77,000 Germans were executed for one or another form of resistance by Special Courts, courts-martial, and the civil justice system. Many of these Germans had served in government, the military, or in civil positions, which enabled them to engage in subversion and conspiracy against the Nazis.[11]
