After Nazi Germany unleashed World War II in September 1939, vast new territorial conquests and larger groups of potential prisoners led to the rapid expansion of the concentration camp system to the east. The war did not change the original function of the concentration camps as detention sites for the incarceration of political enemies. The climate of national emergency that the conflict granted to the Nazi leaders, however, permitted the SS to expand the functions of the camps.
After roll call, to the sound of "Arbeitskommandos formieren" ("form work details"), prisoners walked to their place of work, five abreast, to begin a working day that was normally 11 hours long—longer in summer and shorter in winter.[112] A prison orchestra, such as the Women's Orchestra of Auschwitz, was forced to play cheerful music as the workers left the camp. Kapos were responsible for the prisoners' behavior while they worked, as was an SS escort. Much of the work took place outdoors at construction sites, gravel pits, and lumber yards. No rest periods were allowed. One prisoner was assigned to the latrines to measure the time the workers took to empty their bladders and bowels.[111][113]
The 1930 elections changed the German political landscape by weakening the traditional nationalist parties, the DNVP and the DVP, leaving the Nazis as the chief alternative to the discredited Social Democrats and the Zentrum, whose leader, Heinrich Brüning, headed a weak minority government. The inability of the democratic parties to form a united front, the self-imposed isolation of the Communists and the continued decline of the economy, all played into Hitler's hands. He now came to be seen as de facto leader of the opposition and donations poured into the Nazi Party's coffers. Some major business figures, such as Fritz Thyssen, were Nazi supporters and gave generously[71] and some Wall Street figures were allegedly involved,[72] but many other businessmen were suspicious of the extreme nationalist tendencies of the Nazis and preferred to support the traditional conservative parties instead.[73]
On July 15, 1944, three weeks before the hiding place where she lived with her family and several others was discovered, Anne Frank wrote in her diary: “It’s a wonder I haven’t abandoned all my ideals, they seem so absurd and impractical. Yet I cling to them because I still believe, in spite of everything, that people are truly good at heart.” Anne Frank’s diary, particularly these sentences, became one of the central symbols of the Holocaust and of humanity faced with suffering: the strength of spirit that led a young girl to write such words after two years of imprisonment hidden in a small, crowded attic, decreed on her by senseless evil; and the opening which her words offer for a new era of hope and reconciliation after a world war that claimed tens of millions of victims. These words aroused great admiration for her diary and for the girl herself. Translated into more than fifty languages, the diary sold more than thirty million copies all over the world. Streets and squares, coins and stamps bear Anne’s name, along with prizes, conventions, exhibits, memorials, schools and youth institutions, to say nothing of films and plays that bring her diary to life, and thorough research of various kinds into her character and her diary, its translations and the different uses that have been made and still are being made of it.
Between 1940 and 1942, the French interned Jewish refugee families fleeing Nazi oppression elsewhere in Europe in Rivesaltes for the same reason. Lists of those incarcerated include a transport of Czech Jewish children: Brothers Salomon and Abraham Davidovic were 13 and 14 when they arrived. Conditions deteriorated. Directors complained in 1941 of no heat. Illness spread. Babies and the elderly died. The situation worsened when the Nazi-puppet Vichy regime assumed control of the camp in 1942 and began deporting its 7,000 foreign Jewish refugee prisoners to the gas chambers of Auschwitz. There, mothers and children were not separated but instead went to their deaths together.
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.
Initially the new facilities were "underutilized". From April 1943 to March 1944, "only" 160,000 Jews were killed at Birkenau, but from March 1944 to November 1944, when all the other death camps had been abandoned, Birkenau surpassed all previous records for mass killing. The Hungarian deportations and the liquidation of the remaining Polish ghettos, such as Lodz, resulted in the gassing of 585,000 Jews. This period made Auschwitz-Birkenau into the most notorious killing site of all time.
A Jewish skeleton collection was obtained from among a pool of 115 Jewish Auschwitz inmates, chosen for their perceived stereotypical racial characteristics.[b] Rudolf Brandt and Wolfram Sievers, general manager of the Ahnenerbe (a Nazi research institute), delivered the skeletons to the collection of the Anatomy Institute at the Reichsuniversität Straßburg in Occupied France. The collection was sanctioned by Himmler and under the direction of August Hirt. Ultimately 87 of the inmates were shipped to Natzweiler-Struthof and killed in August 1943.[135] Brandt and Sievers were executed in 1948 after being convicted during the Doctors' trial, part of the Subsequent Nuremberg trials.[136]
Nazi plunder included private and public art collections, artefacts, precious metals, books, and personal possessions. Hitler and Göring in particular were interested in acquiring looted art treasures from occupied Europe,[291] the former planning to use the stolen art to fill the galleries of the planned Führermuseum (Leader's Museum),[292] and the latter for his personal collection. Göring, having stripped almost all of occupied Poland of its artworks within six months of Germany's invasion, ultimately grew a collection valued at over 50 million Reichsmarks.[291] In 1940, the Reichsleiter Rosenberg Taskforce was established to loot artwork and cultural material from public and private collections, libraries, and museums throughout Europe. France saw the greatest extent of Nazi plunder. Some 26,000 railroad cars of art treasures, furniture, and other looted items were sent to Germany from France.[293] By January 1941, Rosenberg estimated the looted treasures from France to be valued at over one billion Reichsmarks.[294] In addition, soldiers looted or purchased goods such as produce and clothing—items, which were becoming harder to obtain in Germany—for shipment home.[295]

The prisoners put up various forms of resistance to the tyranny of the camp. Resistance organisations helped inmates to obtain medicine and food, documented Nazi crimes, supported attempts to escape and sabotage, tried to put political prisoners into positions of responsibility, and prepared for an uprising. A total of 667 prisoners escaped from Auschwitz, but 270 of them were caught in the vicinity of the camp and immediately executed. The best-known escape was that of two Slovak Jews, Alfred Wetzler and Walter Rosenberg (Rudolf Vrba) (link in Czech). They managed to cross into Slovakia and to tell Jewish leaders - and through them the world - about the terrible reality of Auschwitz, about which they wrote an extensive report. On the 7th of October 1944, there was an uprising by the Sonderkommando working in the gas chambers. The prisoners managed to destroy one of the gas chambers, and thus to hinder the extermination process. All the rebels died. A group of young female prisoners was also executed for having smuggled gunpowder to the rebels from the factory in Monowitz.

Auschwitz-Birkenau, Nazi Germany's largest concentration and extermination camp facility, was located nearby the provincial Polish town of Oshwiecim in Galacia, and was established by order of Reichsfuhrer SS Heinrich Himmler on 27 April 1940. Private diaries of Goebbels and Himmler unearthed from the secret Soviet archives show that Adolf Hitler personally ordered the mass extermination of the Jews during a meeting of Nazi German regional governors in the chancellery. As Goebbels wrote "With regards to the Jewish question, the Fuhrer decided to make a clean sweep ..."
“Faces of Auschwitz” is a collaboration between the Auschwitz-Birkenau Museum, a Brazilian photo colorization specialist Marina Amaral, and a dedicated team of academics, journalists and volunteers. The goal of the project is to honor the memory and lives of Auschwitz-Birkenau prisoners by colorizing registration photographs culled from the museum’s archive and sharing individual stories of those whose faces were photographed.

Wonderful book, the like of which I haven't seen elsewhere. So many wonderful passages, insights into life such as you rarely find anywhere. Anne's ruminations captured here were for herself, from the heart. Writing this helped so much in making her life tolerable during this very difficult period in her life. Toward the end, I found it difficult to plow to the end, knowing that she tragically did not survive. However, she was unaware that their arrest was imminent, so the unfortunate ending is not implicit in Anne's writing. She just may as well have survived and gone on to have the wonderful life and career she very much deserved. I have read a lot about WW II, but this book succeeded in doing what all the other readings did not for me -- it made me feel that I was living through it myself.
Many of the forced labour camps were satellite camps or sections of concentration camps. Auschwitz, in Poland, had over 40 such satellite camps. Inmates of the labour camps were kept in terrible conditions, with the intention by the Nazis that death would be the result. ‘Extermination by labour’ was a policy under which the Nazis could supply the German war effort, while also continuing to carry out ‘the final solution’.

Major public works projects financed with deficit spending included the construction of a network of Autobahnen and providing funding for programmes initiated by the previous government for housing and agricultural improvements.[258] To stimulate the construction industry, credit was offered to private businesses and subsidies were made available for home purchases and repairs.[259] On the condition that the wife would leave the workforce, a loan of up to 1,000 Reichsmarks could be accessed by young couples of Aryan descent who intended to marry, and the amount that had to be repaid was reduced by 25 percent for each child born.[260] The caveat that the woman had to remain unemployed outside the home was dropped by 1937 due to a shortage of skilled labourers.[261]
After December 1934, the SS became the only agency authorized to establish and manage facilities that were formally called concentration camps. Local civilian authorities did continue to establish and manage forced-labor camps and detention camps throughout Germany. In 1937, only four concentration camps were left: Dachau, near Munich; Sachsenhausen near Berlin; Buchenwald near Weimar; and Lichtenburg near Merseburg in Saxony for female prisoners.
There have been protracted disputes over the perceived Christianization of the site. Pope John Paul II celebrated mass over the train tracks leading to Auschwitz II-Birkenau on 7 June 1979,[291] and called the camp "the Golgotha of our age", referring to the crucifixion of Jesus.[292] More controversy followed when Carmelite nuns founded a convent in 1984 in a former theater outside the camp's perimeter, near block 11 of Auschwitz I,[293] after which a local priest and some survivors erected a large cross—one that had been used during the pope's mass—behind block 11 to commemorate 152 Polish inmates shot by the Germans in 1941.[294][295] After a long dispute, Pope John Paul II intervened, and the nuns moved the convent elsewhere in 1993.[296] The cross remained, triggering the "War of the Crosses", as more crosses were erected to commemorate Christian victims, despite international objections. The Polish government and Catholic Church eventually agreed to remove all but the original.[297]
Discrimination against Jews began immediately after the seizure of power. Following a month-long series of attacks by members of the SA on Jewish businesses and synagogues, on 1 April 1933 Hitler declared a national boycott of Jewish businesses.[299] The Law for the Restoration of the Professional Civil Service passed on 7 April forced all non-Aryan civil servants to retire from the legal profession and civil service.[300] Similar legislation soon deprived other Jewish professionals of their right to practise, and on 11 April a decree was promulgated that stated anyone who had even one Jewish parent or grandparent was considered non-Aryan.[301] As part of the drive to remove Jewish influence from cultural life, members of the National Socialist Student League removed from libraries any books considered un-German, and a nationwide book burning was held on 10 May.[302]

[Hitler] compiled a most extensive set of revolutionary goals (calling for radical social and political change); he mobilized a revolutionary following so extensive and powerful that many of his aims were achieved; he established and ran a dictatorial revolutionary state; and he disseminated his ideas abroad through a revolutionary foreign policy and war. In short, he defined and controlled the National Socialist revolution in all its phases.[283]

On 6 June 1944, American, British, and Canadian forces established a front in France with the D-Day landings in Normandy.[133] On 20 July 1944, Hitler survived an assassination attempt.[134] He ordered brutal reprisals, resulting in 7,000 arrests and the execution of more than 4,900 people.[135] The failed Ardennes Offensive (16 December 1944 – 25 January 1945) was the last major German offensive on the western front, and Soviet forces entered Germany on 27 January.[136] Hitler's refusal to admit defeat and his insistence that the war be fought to the last man led to unnecessary death and destruction in the war's closing months.[137] Through his Justice Minister Otto Georg Thierack, Hitler ordered that anyone who was not prepared to fight should be court-martialed, and thousands of people were put to death.[138] In many areas, people surrendered to the approaching Allies in spite of exhortations of local leaders to continue to fight. Hitler ordered the destruction of transport, bridges, industries, and other infrastructure—a scorched earth decree—but Armaments Minister Albert Speer prevented this order from being fully carried out.[137]

Hitler had the final say in both domestic legislation and German foreign policy. Nazi foreign policy was guided by the racist belief that Germany was biologically destined to expand eastward by military force and that an enlarged, racially superior German population should establish permanent rule in eastern Europe and the Soviet Union. Here, women played a vital role. The Third Reich's aggressive population policy encouraged "racially pure" women to bear as many "Aryan" children as possible.
The SS gained its independence from the SA in July 1934, in the wake of the Röhm purge. Hitler then authorized SS leader Heinrich Himmler to centralize the administration of the concentration camps and formalize them into a system. Himmler chose SS Lieutenant General Theodor Eicke for this task. Eicke had been the commandant of the SS concentration camp at Dachau since June 1933. Himmler appointed him Inspector of Concentration Camps, a new section of the SS subordinate to the SS Main Office.
The Nazi Party grew significantly during 1921 and 1922, partly through Hitler's oratorical skills, partly through the SA's appeal to unemployed young men, and partly because there was a backlash against socialist and liberal politics in Bavaria as Germany's economic problems deepened and the weakness of the Weimar regime became apparent. The party recruited former World War I soldiers, to whom Hitler as a decorated frontline veteran could particularly appeal, as well as small businessmen and disaffected former members of rival parties. Nazi rallies were often held in beer halls, where downtrodden men could get free beer. The Hitler Youth was formed for the children of party members. The party also formed groups in other parts of Germany. Julius Streicher in Nuremberg was an early recruit and became editor of the racist magazine Der Stürmer. In December 1920, the Nazi Party had acquired a newspaper, the Völkischer Beobachter, of which its leading ideologist Alfred Rosenberg became editor. Others to join the party around this time were Heinrich Himmler and World War I flying ace Hermann Göring.
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.
Adolf Hitler was released from prison on 20 December 1924. On 16 February 1925, Hitler convinced the Bavarian authorities to lift the ban on the NSDAP and the party was formally refounded on 26 February 1925, with Hitler as its undisputed leader. The new Nazi Party was no longer a paramilitary organisation and disavowed any intention of taking power by force. In any case, the economic and political situation had stabilised and the extremist upsurge of 1923 had faded, so there was no prospect of further revolutionary adventures. The Nazi Party of 1925 was divided into the "Leadership Corps" (Korps der politischen Leiter) appointed by Hitler and the general membership (Parteimitglieder). The party and the SA were kept separate and the legal aspect of the party's work was emphasised. In a sign of this, the party began to admit women. The SA and the SS members (the latter founded in 1925 as Hitler's bodyguard, and known originally as the Schutzkommando) had to all be regular party members.[68][69]
On the morning of 4 August 1944, the Achterhuis was stormed by a group of German uniformed police (Grüne Polizei) led by SS-Oberscharführer Karl Silberbauer of the Sicherheitsdienst.[37] The Franks, van Pelses, and Pfeffer were taken to RSHA headquarters, where they were interrogated and held overnight. On 5 August they were transferred to the Huis van Bewaring (House of Detention), an overcrowded prison on the Weteringschans. Two days later they were transported to the Westerbork transit camp, through which by that time more than 100,000 Jews, mostly Dutch and German, had passed. Having been arrested in hiding, they were considered criminals and sent to the Punishment Barracks for hard labour.[38]
While civilian efforts had an impact on public opinion, the army was the only organisation with the capacity to overthrow the government.[443][444] A major plot by men in the upper echelons of the military originated in 1938. They believed Britain would go to war over Hitler's planned invasion of Czechoslovakia, and Germany would lose. The plan was to overthrow Hitler or possibly assassinate him. Participants included Generaloberst Ludwig Beck, Generaloberst Walther von Brauchitsch, Generaloberst Franz Halder, Admiral Wilhelm Canaris, and Generalleutnant Erwin von Witzleben, who joined a conspiracy headed by Oberstleutnant Hans Oster and Major Helmuth Groscurth of the Abwehr. The planned coup was cancelled after the signing of the Munich Agreement in September 1938.[445] Many of the same people were involved in a coup planned for 1940, but again the participants changed their minds and backed down, partly because of the popularity of the regime after the early victories in the war.[446][447] Attempts to assassinate Hitler resumed in earnest in 1943, with Henning von Tresckow joining Oster's group and attempting to blow up Hitler's plane in 1943. Several more attempts followed before the failed 20 July 1944 plot, which was at least partly motivated by the increasing prospect of a German defeat in the war.[448][449] The plot, part of Operation Valkyrie, involved Claus von Stauffenberg planting a bomb in the conference room at Wolf's Lair at Rastenburg. Hitler, who narrowly survived, later ordered savage reprisals resulting in the execution of more than 4,900 people.[450]
None of the categories are independent - one could classify many camps as a mixture of several of the above. All camps had some of the elements of an extermination camp, but systematic extermination of new arrivals by gas chambers only occurred in specialized camps. These were extermination camps, where all new-arrivals were simply killed—the "Aktion Reinhard" camps (Treblinka, Sobibór and Belzec), together with Chelmno. Two others ( Auschwitz and Majdanek) operated as combined concentration- and extermination-camps. Others like Maly Trostenets were at times classified[by whom?] as "minor extermination camps".[50]
