On 15 September 1935, the Reichstag passed the Nuremberg Laws, prohibiting marriages between Jews and people of Germanic extraction, extramarital relations between Jews and Germans, and the employment of German women under the age of 45 as domestic servants in Jewish households. The Reich Citizenship Law defined as citizens those of "German or kindred blood". Thus Jews and other minorities were stripped of their citizenship. By the start of World War II in 1939, around 250,000 of Germany's 437,000 Jews had emigrated to the United States, Palestine, the United Kingdom, and other countries.
German authorities established camps all over Germany on an ad hoc basis to handle the masses of people arrested as alleged subversives. The SS established larger camps in Oranienburg, north of Berlin; Esterwegen, near Hamburg; Dachau, northwest of Munich; and Lichtenburg, in Saxony. In Berlin itself, the Columbia Haus facility held prisoners under investigation by the Gestapo (the German secret state police) until 1936.
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.
Construction of crematorium I began at Auschwitz I at the end of June or beginning of July 1940. Initially intended not for mass murder but for prisoners who had been executed or had otherwise died in the camps, the crematorium was in operation from August 1940 until July 1943, by which time the crematoria at Auschwitz II had taken over. By May 1942 three ovens had been installed in crematorium I, which together could burn 340 bodies in 24 hours.
In 2015, Flemish journalist Jeroen de Bruyn and Joop van Wijk, Bep Voskuijl's youngest son, wrote a biography, Bep Voskuijl, het zwijgen voorbij: een biografie van de jongste helper van het Achterhuis (Bep Voskuijl, the Silence is Over: A Biography of the Youngest Helper of the Secret Annex), in which they alleged that Bep's younger sister Nelly (1923–2001) could have betrayed the Frank family. According to the book, Bep's sister Diny and her fiancé Bertus Hulsman recollected Nelly telephoning the Gestapo on the morning of 4 August 1944. Nelly had been critical of Bep and their father, Johannes Voskuijl, helping the Jews. (Johannes was the one who constructed the bookcase covering the entrance to the hiding place.) Nelly was a Nazi collaborator between the ages of 19 and 23. Karl Silberbauer, the SS officer who received the phone call and made the arrest, was documented to say that the informer had "the voice of a young woman".
Before Auschwitz became the ultimate symbol of the Holocaust, it was an ordinary Polish town known as Oświęcim, where Jews made their home from the early 16th century until the Holocaust, when most of them were murdered. In the pre-war years, the majority of Oświęcim’s citizens were Jewish, and for generations they raised families here and contributed to a richly textured culture. The Holocaust suddenly ended the vibrant Jewish life of the town.
Nazi racial theorist Hans F. K. Günther argued that European peoples were divided into five races: Nordic, Mediterranean, Dinaric, Alpine and East Baltic. Günther applied a Nordicist conception in order to justify his belief that Nordics were the highest in the racial hierarchy. In his book Rassenkunde des deutschen Volkes (1922) ("Racial Science of the German People"), Günther recognised Germans as being composed of all five races, but emphasized the strong Nordic heritage among them. Hitler read Rassenkunde des deutschen Volkes, which influenced his racial policy. Gunther believed that Slavs belonged to an "Eastern race" and he warned against Germans mixing with them. The Nazis described Jews as being a racially mixed group of primarily Near Eastern and Oriental racial types. Because such racial groups were concentrated outside Europe, the Nazis claimed that Jews were "racially alien" to all European peoples and that they did not have deep racial roots in Europe.
Fifteen defendants were found guilty, and eight were acquitted. Of the 15, seven were given the death penalty and eight imprisoned. Herta Oberhauser, the doctor who had rubbed crushed glass into the wounds of her subjects, received a 20 year sentence but was released in April 1952 and became a family doctor at Stocksee in Germany. Her license to practice medicine was revoked in 1958.
At Auschwitz, there was a team of Nazi doctors who conducted experiments, but the two most notorious were Dr. Carl Clauberg and Dr. Josef Mengele. Dr. Clauberg focused his attention on finding ways to sterilize women, by such unorthodox methods as X-rays and injections of various substances into their uteruses. Dr. Mengele experimented on identical twins, hoping to find a secret to cloning what Nazis considered the perfect Aryan.
After the failure of the Beer Hall Putsch in 1923, and his subsequent trial and imprisonment, Hitler decided that the way for the Nazi Party to achieve power was not through insurrection, but through legal and quasi-legal means. This did not sit well with the brown-shirted stormtroopers of the SA, especially those in Berlin, who chafed under the restrictions that Hitler placed on them, and their subordination to the party. This resulted in the Stennes Revolt of 1930-31, after which Hitler made himself the Supreme Commander of the SA, and brought Ernst Röhm back to be their Chief of Staff and keep them in line. The quashing of the SA's revolutionary fervor convinced many businessmen and military leaders that the Nazis had put aside their insurrectionist past, and that Hitler could be a reliable partner

I did go back to my home town, Radom, just once in 1996 or 1998. I saw our house, and stood in the backyard, but my heart was bleeding so much, I didn’t dare go in. I walked up the street and it was like walking on history – something lost and far away, but also very close. Here was the road on which I used to run to school, to the factory, but I had to get away very quickly. I was thinking: “I’m here, but where are all of them, my family?”
Selections for transit were a regular feature at Westerbork. Each Monday evening a train of about 20 cattle wagons would arrive at the camp. A list of one thousand people would be compiled by the Jewish council, which was made up of leaders of the community appointed by the Nazis and forced to carry out the Nazis’ orders. Early on the Tuesday morning those selected would assemble for deportation. After a roll call, they would enter the trains, at least 50 to each wagon, a bucket of water at one end and an empty one for use as a toilet at the other. The doors would close before the train departed for the long journey to the intended destination.
Under Nazi rule, all other political parties were banned. In 1933, the Nazis opened their first concentration camp, in Dachau, Germany, to house political prisoners. Dachau evolved into a death camp where countless thousands of Jews died from malnutrition, disease and overwork or were executed. In addition to Jews, the camp’s prisoners included members of other groups Hitler considered unfit for the new Germany, including artists, intellectuals, Gypsies, the physically and mentally handicapped and homosexuals.
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. His hope was that each SS family would have between four and six children. The Lebensborn (Fountain of Life) association, founded by Himmler in 1935, created a series of maternity homes to accommodate single mothers during their pregnancies. Both parents were examined for racial suitability before acceptance. The resulting children were often adopted into SS families. The homes were also made available to the wives of SS and NSDAP members, who quickly filled over half the available spots.
Hitler also relied on terror to achieve his goals. Lured by the wages, a feeling of comradeship, and the striking uniforms, tens of thousands of young jobless men put on the brown shirts and high leather boots of the Nazi Storm Troopers (Sturmabteilungen). Called the SA, these auxiliary policemen took to the streets to beat up and kill some opponents of the Nazi regime. Mere fear of the SA pressured into silence other Germans who did not support the Nazis.
Auschwitz was the Nazis' largest concentration and extermination camp. It was founded on Himmler's orders on the 27th of April 1940, close to the small Polish town of Oświęcim. The first inmates - mostly Polish political prisoners - were brought there in June 1940 and were used for slave labour. By March 1941, more than 10 000 prisoners were registered here. The Auschwitz camp was renowned for its harshness, with the most infamous being Block 11 (known as the bunker), where prisoners received the cruellest punishments. In front of it stood the „black wall“, the site of frequent executions. The inscription „Arbeit macht frei!“ above the main gate of the original camp at Auschwitz was merely a cynical mockery.
When I was eight years old Czechoslovakia broke apart and we became part of Hungary. That was when our problems started, because the Hungarians were allied with the Nazis. It was a difficult time for Jewish families, as suddenly the law no longer protected us and overnight we lost our civil rights. My father’s lumber business was confiscated and given to a non-Jew, and we received no compensation. Jewish children were thrown out of Hungarian schools, so right away we had no choice but to concentrate on hunkering down and trying not to bring attention to ourselves. We couldn’t ride the trains and we had to wear the yellow star. It was a free for all. With no law to protect us, it was common for Jews to get beaten up or thrown off the train.
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.
“Those of us who went through the war and tried to write about it...became messengers,” wrote Elie Wiesel, shown as a young man at left. “We have given the message and nothing changed.” Right: Buchenwald in April 1945. Elie Wiesel is in the second row, seventh from left. Bergen-Belsen, where Anne Frank died, was also liberated that week. (Chicago Public Library; BuyEnlarge Archive / UIG / Bridgeman Images)
Schneidermann doesn’t offer a neat solution to the contradictions that he unearths, but he does give a few other examples of work that has aged well. The American columnist Dorothy Thompson, Schneidermann says, saw Hitler immediately for what he was, describing him, in 1932, as a man “without form, without expression, his face a caricature . . . his movements without dignity, anything but martial.” Thompson offered a lucid assessment of Nazism as a “repudiation of the history of western man, of Reason, Humanism, and the Christian ethic.” She was kicked out of Germany in 1934, but remained a tireless advocate against Nazi Germany. This strategy may not be available to every journalist, but Schneidermann also admires Georges Duhamel, a correspondent for Le Figaro, who faced certain pressures from his conservative bourgeois editors and readers in Paris not to moralize. On June 23, 1938, Le Figaro ran as a front-page headline a question that Duhamel, given the chance to interview Nazi leaders, would have asked: “What do you intend to do with the Jews?” In its simplicity, its directness, its willingness to seem naïve, Schneidermann finds it hauntingly unimpeachable.
A column of inmates reached the Gross-Rosen complex. Throughout February, the terribly overcrowded main camp at Gross-Rosen was cleared, and all 44,000 inmates were moved further west. An unknown number died in this last journey. In March 1945, Himmler ordered that no more prisoners should be killed, as he hoped to use them as hostages in negotiations with the Allies. Approximately 20,000 Auschwitz prisoners made it to Bergen-Belsen, where they were liberated by the British in April 1945.
On the night of the 27 February 1933 and 28 February 1933, someone set the Reichstag building on fire. This was the building where the German Parliament held their meetings. The Nazis blamed the communists. Opponents of the Nazis said that the Nazis themselves had done it to come to power. On the very same day, an emergency law called Reichstagsbrandverordnung was passed. The government claimed it was to protect the state from people trying to hurt the country. With this law, most of the civil rights of the Weimar Republic did not count any longer. The Nazis used this against the other political parties. Members of the communist and social-democratic parties were put into prison or killed.
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 Parteiflagge design, with the centred swastika disc, served as the party flag from 1920. Between 1933 (when the Nazi Party came to power) and 1935, it was used as the National flag (Nationalflagge) and Merchant flag (Handelsflagge), but interchangeably with the black-white-red horizontal tricolour. In 1935, the black-white-red horizontal tricolour was scrapped (again) and the flag with the off-centre swastika and disc was instituted as the national flag, and remained as such until 1945. The flag with the centred disk continued to be used after 1935, but exclusively as the Parteiflagge, the flag of the party.
Hitler added to Pan-Germanic aspirations the almost mystical fanaticism of a faith in the mission of the German race and the fervour of a social revolutionary gospel. This gospel was most fully expressed in Hitler’s personal testament Mein Kampf (1925–27; “My Struggle”), in which he outlined both his practical aims and his theories of race and propaganda.
Other former staff were hanged for war crimes in the Dachau Trials and the Belsen Trial, including camp leaders Josef Kramer, Franz Hössler, and Vinzenz Schöttl; doctor Friedrich Entress; and guards Irma Grese and Elisabeth Volkenrath. The Frankfurt Auschwitz trials, held in West Germany from 20 December 1963 to 20 August 1965, convicted 17 of 22 defendants, giving them prison sentences ranging from life to three years and three months. Bruno Tesch and Karl Weinbacher, the owner and the chief executive officer of the firm Tesch & Stabenow, one of the suppliers of Zyklon B, were executed for knowingly supplying the chemical for use on humans.
The fate of the Frank family and other Jews in Amsterdam was wrapped up with the German occupation of the city, which began in May 1940. In July 1942, German authorities and their Dutch collaborators began to concentrate Jews from throughout the Netherlands at Westerbork, a transit camp near the Dutch town of Assen, not far from the German border. From Westerbork, German officials deported the Jews to Auschwitz-Birkenau and Sobibor killing centers in German-occupied Poland.
Frank’s subsequent books and essays continued to win praise, if not popularity, earning her a reputation as a clear-eyed prophet carefully attuned to hypocrisy. Her readers will long remember the words she wrote in her diary at 15, included in the otherwise naive first section of "The House Behind": “I don’t believe that the big men are guilty of the war, oh no, the little man is just as guilty, otherwise the peoples of the world would have risen in revolt long ago! There’s in people simply an urge to destroy, an urge to kill, to murder and rage, and until all mankind without exception undergoes a great change, wars will be waged, everything that has been built up, cultivated and grown will be cut down and disfigured, and mankind will have to begin all over again.”
Birkenau was the largest camp in the Auschwitz complex. It became primarily a centre for the mass murder of Jews brought there for extermination, and of Roma and Sinti prisoners during its final period. Sick prisoners and those selected for death from the whole Auschwitz complex – and, to a smaller extent, from other camps – were also gathered and systematically killed here. It ultimately became a place for the concentration of prisoners before they were transferred inside the Third Reich to work for German industry. Most of the victims of the Auschwitz complex, probably about 90%, were killed in the Birkenau camp.
On October 7, 1944, several hundred prisoners assigned to Crematorium IV at Auschwitz-Birkenau rebelled after learning that they were going to be killed. During the uprising, the prisoners killed three guards and blew up the crematorium and adjacent gas chamber. The prisoners used explosives smuggled into the camp by Jewish women who had been assigned to forced labor in a nearby armaments factory.
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. 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."
