When it came to power in 1933, the Nazi Party had over 2 million members. In 1939, the membership total rose to 5.3 million with 81% being male and 19% being female. It continued to attract many more and by 1945 the party reached its peak of 8 million with 63% being male and 37% being female (about 10% of the German population of 80 million).[2][116]
During 1931 and into 1932, Germany's political crisis deepened. Hitler ran for President against the incumbent Paul von Hindenburg in March 1932, polling 30.1% in the first round and 36.8% in the second against Hindenburg's 49% and 53%. By now the SA had 400,000 members and its running street battles with the SPD and Communist paramilitaries (who also fought each other) reduced some German cities to combat zones. Paradoxically, although the Nazis were among the main instigators of this disorder, part of Hitler's appeal to a frightened and demoralised middle class was his promise to restore law and order. Overt antisemitism was played down in official Nazi rhetoric, but was never far from the surface. Germans voted for Hitler primarily because of his promises to revive the economy (by unspecified means), to restore German greatness and overturn the Treaty of Versailles and to save Germany from communism. On 24 April 1932, the Free State of Prussia elections to the Landtag resulted in 36.3% of the votes and 162 seats for the NSDAP.
Born in Baden-Baden in 1900,[78] SS Obersturmbannführer Rudolf Höss became the first commandant of Auschwitz when the camp was founded in April 1940,[79] living with his wife and children in a villa just outside the camp grounds.[80] Appointed by Heinrich Himmler, he served until 11 November 1943, when he became director of Office DI of the SS-Wirtschafts-und Verwaltungshauptamt (SS Business and Administration Head Office or WVHA) in Oranienburg.[79] This post made Höss deputy of the Concentration Camps Inspectorate, under SS-Gruppenführer Richard Glücks.[81] He returned to Auschwitz between 8 May and 29 July 1944 as commander of the SS garrison (Standortältester) to oversee the arrival of Hungary's Jews, a post that made him the superior officer of all the commandants of the Auschwitz camps.[82]
The most infamous doctor at Auschwitz was Josef Mengele, the "Angel of Death", who worked in Auschwitz II from 30 May 1943, at first in the gypsy family camp.[127] Particularly interested in performing research on identical twins, dwarfs, and those with hereditary disease, Mengele set up a kindergarten in barracks 29 and 31 for children he was experimenting on, and for all Romani children under six, where they were given better food rations.[128] From May 1944, he would select twins and dwarfs during selection on the Judenrampe,[129] reportedly calling for twins with "Zwillinge heraus!" ("twins step forward!").[130] He and other doctors (the latter prisoners) would measure the twins' body parts, photograph them, and subject them to dental, sight and hearing tests, x-rays, blood tests, surgery, and blood transfusions between them.[131] Then he would have them killed and dissected.[129] Kurt Heissmeyer, another German doctor and SS officer, took 20 Jewish children from Auschwitz to use in pseudoscientific medical experiments at the Neuengamme concentration camp.[132] In April 1945, the children were killed by hanging to conceal the project.[133]

It was first published in Germany and France in 1950, and after being rejected by several publishers, was first published in the United Kingdom in 1952. The first American edition, published in 1952 under the title Anne Frank: The Diary of a Young Girl, was positively reviewed. The book was successful in France, Germany, and the United States, but in the United Kingdom it failed to attract an audience and by 1953 was out of print. Its most noteworthy success was in Japan, where it received critical acclaim and sold more than 100,000 copies in its first edition. In Japan, Anne Frank quickly was identified as an important cultural figure who represented the destruction of youth during the war.[72]
Despite these strengths, the Nazi Party might never have come to power had it not been for the Great Depression and its effects on Germany. By 1930, the German economy was beset with mass unemployment and widespread business failures. The Social Democrats and Communists were bitterly divided and unable to formulate an effective solution: this gave the Nazis their opportunity and Hitler's message, blaming the crisis on the Jewish financiers and the Bolsheviks, resonated with wide sections of the electorate. At the September 1930 Reichstag elections, the Nazis won 18.3% of the votes and became the second-largest party in the Reichstag after the Social Democrats. Hitler proved to be a highly effective campaigner, pioneering the use of radio and aircraft for this purpose. His dismissal of Strasser and his appointment of Goebbels as the party's propaganda chief were major factors. While Strasser had used his position to promote his own leftish version of national socialism, Goebbels was totally loyal to Hitler and worked only to improve Hitler's image.

Some of the conquered territories were incorporated into Germany as part of Hitler's long-term goal of creating a Greater Germanic Reich. Several areas, such as Alsace-Lorraine, were placed under the authority of an adjacent Gau (regional district). The Reichskommissariate (Reich Commissariats), quasi-colonial regimes, were established in some occupied countries. Areas placed under German administration included the Protectorate of Bohemia and Moravia, Reichskommissariat Ostland (encompassing the Baltic states and Belarus), and Reichskommissariat Ukraine. Conquered areas of Belgium and France were placed under control of the Military Administration in Belgium and Northern France.[167] Belgian Eupen-Malmedy, which had been part of Germany until 1919, was annexed. Part of Poland was incorporated into the Reich, and the General Government was established in occupied central Poland.[168] The governments of Denmark, Norway (Reichskommissariat Norwegen), and the Netherlands (Reichskommissariat Niederlande) were placed under civilian administrations staffed largely by natives.[167][g] Hitler intended to eventually incorporate many of these areas into the Reich.[169] Germany occupied the Italian protectorate of Albania and the Italian governorate of Montenegro in 1943[170] and installed a puppet government in occupied Serbia in 1941.[171]
The orders for the final evacuation and liquidation of the camp were issued in mid-January 1945. The Germans left behind in the main Auschwitz camp, Birkenau and in Monowitz about 7,000 sick or incapacitated who they did not expect would live for long; the rest, approximately 58,000 people, were evacuated by foot into the depths of the Third Reich.
After the war, the Allied governments, such as the United States, Britain, and the Soviet Union, held trials for the Nazi leaders. These trials were held in Nuremberg, in Germany. For this reason, these trials were called "the Nuremberg Trials." The Allied leaders accused the Nazi leaders of war crimes and crimes against humanity, including murdering millions of people (in the Holocaust), of starting wars, of conspiracy, and belonging to illegal organizations like the Schutzstaffel (SS). Most Nazi leaders were found guilty by the court, and they were sent to jail or executed by hanging.

Within this framework, "racially inferior" peoples, such as Jews and Gypsies, would be eliminated from the region. Nazi foreign policy aimed from the beginning to wage a war of annihilation against the Soviet Union, and the peacetime years of the Nazi regime were spent preparing the German people for war. In the context of this ideological war, the Nazis planned and implemented the Holocaust, the mass murder of the Jews, who were considered the primary "racial" enemy.
In early 1942, at the Wannsee Conference near Berlin, the Nazi Party decided on the last phase of what it called the “Final Solution” of the “Jewish problem” and spelled out plans for the systematic murder of all European Jews. In 1942 and 1943, Jews in the western occupied countries including France and Belgium were deported by the thousands to the death camps mushrooming across Europe. In Poland, huge death camps such as Auschwitz began operating with ruthless efficiency. The murder of Jews in German-occupied lands stopped only in last months of the war, as the German armies were retreating toward Berlin. By the time Hitler committed suicide in April 1945, some 6 million Jews had died.
The enormous expansion of the camps resulted in an exponential increase in the misery of the prisoners. Food rations, always meagre, were cut to less than minimal: a bowl of rutabaga soup and some ersatz bread would have to sustain a prisoner doing heavy labor. The result was desperate black marketing and theft. Wachsmann writes, “In Sachsenhausen, a young French prisoner was battered to death in 1941 by an SS block leader for taking two carrots from a sheep pen.” Starvation was endemic and rendered prisoners easy prey for typhus and dysentery. At the same time, the need to keep control of so many prisoners made the S.S. even more brutal, and sadistic new punishments were invented. The “standing commando” forced prisoners to stand absolutely still for eight hours at a time; any movement or noise was punished by beatings. The murder of prisoners by guards, formerly an exceptional event in the camps, now became unremarkable.

There is no more forceful advocate for the preservation of Auschwitz than Wladyslaw Bartoszewski. Born in Warsaw in 1922, Bartoszewski, 87, was a Red Cross stretcher-bearer when the German Army invaded the capital city in September 1939. Plucked off the street by German soldiers a year later, he was sent to Auschwitz. He’d been there seven months when the Red Cross arranged for his release in April 1941—one of the few inmates ever set free.

I remember the night of the packing very well. Things went in the suitcase, things were taken out of the suitcase. In the end my mother filled it with food she had cooked and warm clothing and bedding. Then it was full. Plus we took a watch, some earrings, a wedding ring with us to exchange for food if necessary. The next day my father was forced to hand over his remaining money to a delegation that included the mayor and the school principal as they rounded us up at the town hall.
The process of losing any kind of hope was a very gradual one. We were transported in cattle wagons in which many babies and children suffocated, in what it turned out was the last transport of Hungarians. We had no water, no food, there was no hygiene. That diminished our hope and increased the feeling of being trapped. But despite that, you always retained a glimmer of hope. Always.
One of the first people I encountered was Mengele. He told us to undress and stand in line and he went through the ranks deciding who was strong and healthy and fit for work, and who was only fit for the gas chamber. After inspecting me, he put his thumb up high, so they gave me the striped uniform and sent me to get a number tattooed on to my arm. I don’t remember the number. It’s there still, but I never look at it because it brings back too many painful memories.
At universities, appointments to top posts were the subject of power struggles between the education ministry, the university boards, and the National Socialist German Students' League.[361] In spite of pressure from the League and various government ministries, most university professors did not make changes to their lectures or syllabus during the Nazi period.[362] This was especially true of universities located in predominantly Catholic regions.[363] Enrolment at German universities declined from 104,000 students in 1931 to 41,000 in 1939, but enrolment in medical schools rose sharply as Jewish doctors had been forced to leave the profession, so medical graduates had good job prospects.[364] From 1934, university students were required to attend frequent and time-consuming military training sessions run by the SA.[365] First-year students also had to serve six months in a labour camp for the Reich Labour Service; an additional ten weeks service were required of second-year students.[366]

Germany's war in the East was based on Hitler's long-standing view that Jews were the great enemy of the German people and that Lebensraum was needed for Germany's expansion. Hitler focused his attention on Eastern Europe, aiming to conquer Poland and the Soviet Union.[182][183] After the occupation of Poland in 1939, all Jews living in the General Government were confined to ghettos, and those who were physically fit were required to perform compulsory labour.[317] In 1941 Hitler decided to destroy the Polish nation completely; within 15 to 20 years the General Government was to be cleared of ethnic Poles and resettled by German colonists.[318] About 3.8 to 4 million Poles would remain as slaves,[319] part of a slave labour force of 14 million the Nazis intended to create using citizens of conquered nations.[183][320]

One night in the autumn of 1944, two Frenchwomen—Loulou Le Porz, a doctor, and Violette Lecoq, a nurse—watched as a truck drove in through the main gates of Ravensbrück, the Nazi concentration camp for women. “There was a lorry,” Le Porz recalled, “that suddenly arrives and it turns around and reverses towards us. And it lifts up and it tips out a whole pile of corpses.” These were the bodies of Ravensbrück inmates who had died doing slave labor in the many satellite camps, and they were now being returned for cremation. Talking, decades later, to the historian and journalist Sarah Helm, whose new book, “Ravensbrück: Life and Death in Hitler’s Concentration Camp for Women” (Doubleday), recounts the stories of dozens of the camp’s inmates, Le Porz says that her reaction was simple disbelief. The sight of a truck full of dead bodies was so outrageous, so out of scale with ordinary experience, that “if we recount that one day, we said to each other, nobody would believe us.” The only way to make the scene credible would be to record it: “If one day someone makes a film they must film this scene. This night. This moment.”
A concentration camp to house Soviet prisoners of war and Poles had been established at Majdanek, close to the Polish city of Lublin, during 1941. In the spring of 1942 gas chambers and crematoria were added, turning Majdanek into an extermination camp that would murder 78,000 people. Auschwitz-Birkenau, the most infamous of the Nazi death camps, was a massive concentration, forced labour and extermination camp at the centre of a network of more than 40 satellite camps. Upwards of 80 per cent of those Jews transported to Auschwitz-Birkenau were selected for immediate death.
Women were expected to be strong, healthy, and vital.[378] The sturdy peasant woman who worked the land and bore strong children was considered ideal, and women were praised for being athletic and tanned from working outdoors.[379] Organisations were created for the indoctrination of Nazi values. From 25 March 1939 membership in the Hitler Youth was made compulsory for all children over the age of ten.[380] The Jungmädelbund (Young Girls League) section of the Hitler Youth was for girls age 10 to 14 and the Bund Deutscher Mädel (BDM; League of German Girls) was for young women age 14 to 18. The BDM's activities focused on physical education, with activities such as running, long jumping, somersaulting, tightrope walking, marching, and swimming.[381]

Frank's diary began as a private expression of her thoughts; she wrote several times that she would never allow anyone to read it. She candidly described her life, her family and companions, and their situation, while beginning to recognize her ambition to write fiction for publication. In March 1944, she heard a radio broadcast by Gerrit Bolkestein—a member of the Dutch government in exile, based in London—who said that when the war ended, he would create a public record of the Dutch people's oppression under German occupation.[67] He mentioned the publication of letters and diaries, and Frank decided to submit her work when the time came. She began editing her writing, removing some sections and rewriting others, with a view to publication. Her original notebook was supplemented by additional notebooks and loose-leaf sheets of paper. She created pseudonyms for the members of the household and the helpers. The van Pels family became Hermann, Petronella, and Peter van Daan, and Fritz Pfeffer became Albert Düssell. In this edited version, she addressed each entry to "Kitty," a fictional character in Cissy van Marxveldt's Joop ter Heul novels that Anne enjoyed reading. Otto Frank used her original diary, known as "version A", and her edited version, known as "version B", to produce the first version for publication. He removed certain passages, most notably those in which Anne is critical of her parents (especially her mother), and sections that discussed Frank's growing sexuality. Although he restored the true identities of his own family, he retained all of the other pseudonyms.[68]
When the Soviet army entered Auschwitz on January 27, they found approximately 7,600 sick or emaciated detainees who had been left behind. The liberators also discovered mounds of corpses, hundreds of thousands of pieces of clothing and pairs of shoes and seven tons of human hair that had been shaved from detainees before their liquidation. According to some estimates, between 1.1 million to 1.5 million people, the vast majority of them Jews, died at Auschwitz during its years of operation. An estimated 70,000 to 80,000 Poles perished at the camp, along with 19,000 to 20,000 Gypsies and smaller numbers of Soviet prisoners of war and other individuals.
In 1942, with the Nazis occupying Holland, a thirteen-year-old Jewish girl and her family fled their home in Amsterdam and went into hiding. For the next two years, until their whereabouts were betrayed to the Gestapo, the Franks and another family lived cloistered in the “Secret Annexe” of an old office building. Cut off from the outside world, they faced hunger, boredom, the constant cruelties of living in confined quarters, and the ever-present threat of discovery and death. In her diary Anne Frank recorded vivid impressions of her experiences during this period. By turns thoughtful, moving, and surprisingly humorous, her account offers a fascinating commentary on human courage and frailty and a compelling self-portrait of a sensitive and spirited young woman whose promise was tragically cut short.

Otto, the only survivor of the Franks, returned to Amsterdam after the war to find that her diary had been saved by his secretary, Miep Gies, and his efforts led to its publication in 1947. It was translated from its original Dutch version and first published in English in 1952 as The Diary of a Young Girl, and has since been translated into over 60 languages.
After the death of President Hindenburg on 2 August 1934, Hitler merged the offices of party leader, head of state and chief of government in one, taking the title of Führer und Reichskanzler. The Chancellery of the Führer, officially an organisation of the Nazi Party, took over the functions of the Office of the President (a government agency), blurring the distinction between structures of party and state even further. The SS increasingly exerted police functions, a development which was formally documented by the merger of the offices of Reichsführer-SS and Chief of the German Police on 17 June 1936, as the position was held by Heinrich Himmler who derived his authority directly from Hitler.[86] The Sicherheitsdienst (SD, formally the "Security Service of the Reichsführer-SS") that had been created in 1931 as an intraparty intelligence became the de facto intelligence agency of Nazi Germany. It was put under the Reich Main Security Office (RSHA) in 1939, which then coordinated SD, Gestapo and criminal police, therefore functioning as a hybrid organisation of state and party structures.[87]
I have already said I that our barracks were overcrowded. It should be added that, although these barracks contained toilets and washrooms, neither came up to the most modest demands of modern hygiene. The cleansing of our bodies took place in a special room and was limited to a short washing of the upper extremities with cold water. A weekly warm shower was supposed to be provided, but with the overcrowding of the camp it was several weeks before a bath was available for each one. There was, of course, no toilet paper.

Beginning a pattern that became typical after the war began, economic considerations had an increasing impact on the selection of sites for concentration camps after 1937. For instance, Mauthausen and Flossenbürg were located near large stone quarries. Likewise, concentration camp authorities increasingly diverted prisoners from meaningless, backbreaking labor to still backbreaking and dangerous labor in extractive industries, such as stone quarries and coal mines, and construction labor.
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.
