The Communist Party of Germany (KPD) was the largest Communist Party in the world outside of the Soviet Union, until it was destroyed by the Nazis in 1933.[256] In the 1920s and early 30s, Communists and Nazis often fought each other directly in street violence, with the Nazi paramilitary organizations being opposed by the Communist Red Front and Anti-Fascist Action. After the beginning of the Great Depression, both Communists and Nazis saw their share of the vote increase. However, while the Nazis were willing to form alliances with other parties of the right, the Communists refused to form an alliance with the Social Democratic Party of Germany, the largest party of the left.[257] After the Nazis came to power, they quickly banned the Communist Party under the allegation that it was preparing for revolution and that it had caused the Reichstag fire.[258] Four thousand KPD officials were arrested in February 1933, and by the end of the year 130,000 communists had been sent to concentration camps.[259]
The Nazis claimed that communism was dangerous to the well-being of nations because of its intention to dissolve private property, its support of class conflict, its aggression against the middle class, its hostility towards small business and its atheism.[246] Nazism rejected class conflict-based socialism and economic egalitarianism, favouring instead a stratified economy with social classes based on merit and talent, retaining private property and the creation of national solidarity that transcends class distinction.[247] Historians Ian Kershaw and Joachim Fest argue that in post–World War I Germany, the Nazis were one of many nationalist and fascist political parties contending for the leadership of Germany's anti-communist movement.

Estimates of the total German war dead range from 5.5 to 6.9 million persons.[149] A study by German historian Rüdiger Overmans puts the number of German military dead and missing at 5.3 million, including 900,000 men conscripted from outside of Germany's 1937 borders.[150] Richard Overy estimated in 2014 that about 353,000 civilians were killed in Allied air raids.[151] Other civilian deaths include 300,000 Germans (including Jews) who were victims of Nazi political, racial, and religious persecution[152] and 200,000 who were murdered in the Nazi euthanasia program.[153] Political courts called Sondergerichte sentenced some 12,000 members of the German resistance to death, and civil courts sentenced an additional 40,000 Germans.[154] Mass rapes of German women also took place.[155]

In May 1943 the SS (Schutzstaffel, "Protective Echelon") announced the removal of all remaining Jews in the Netherlands. In a voluntary call-up on May 25, five hundred Jews voluntarily reported for deportation to Westerbork transit camp. The next day, raids were carried out and 3,000 people were rounded up. Most of these people were sent to the Sobibor extermination camp. About 107,000 Dutch Jews were deported during the war—only about 5,000 returned.
From the mid- to late 1930s, Hitler undermined the postwar international order step by step. He withdrew Germany from the League of Nations in 1933, rebuilt German armed forces beyond what was permitted by the Treaty of Versailles, reoccupied the German Rhineland in 1936, annexed Austria in 1938 and invaded Czechoslovakia in 1939. When Nazi Germany moved toward Poland, Great Britain and France countered further aggression by guaranteeing Polish security. Nevertheless, Germany invaded Poland on September 1, 1939, and Great Britain and France declared war on Germany. Six years of Nazi Party foreign policy had ignited World War II.
Thomas Keneally tells in his famous book Schindler's Ark how the women were marched naked to a quartermaster's hut where they were handed the clothes of the dead. Half dead themselves, dressed in rags, they were packed tight into the darkness of freight cars. But the Schindler-women with their heads cropped, many too ill, too hollowed out, to be easily recognised - the Schindler-women giggled like schoolgirls. One of the women, Clara Sternberg, heard an SS guard ask a colleague: 'What's Schindler going to do with all the old women?' 'It's no one's business,' the colleague said. 'Let him open an old people's home if he wants.'

The concentration camps make sense only if they are understood as products not of reason but of ideology, which is to say, of fantasy. Nazism taught the Germans to see themselves as a beleaguered nation, constantly set upon by enemies external and internal. Metaphors of infection and disease, of betrayal and stabs in the back, were central to Nazi discourse. The concentration camp became the place where those metaphorical evils could be rendered concrete and visible. Here, behind barbed wire, were the traitors, Bolsheviks, parasites, and Jews who were intent on destroying the Fatherland.
Auschwitz I (or "the Main Camp") was the original camp. This camp housed prisoners, was the location of medical experiments, and the site of Block 11 (a place of severe torture) and the Black Wall (a place of execution). At the entrance of Auschwitz, I stood the infamous sign that stated "Arbeit Macht Frei" ("work makes one free"). Auschwitz I also housed the Nazi staff that ran the entire camp complex.
The irregular Swiss branch of the Nazi Party also established a number of Party Gaue in that country, most of them named after their regional capitals. These included Gau Basel-Solothurn, Gau Schaffhausen, Gau Luzern, Gau Bern and Gau Zürich.[111][112][113] The Gau Ostschweiz (East Switzerland) combined the territories of three cantons: St. Gallen, Thurgau and Appenzell.[114]
On her thirteenth birthday, just before they went into hiding, Anne was presented with a diary. During the two years in hiding, Anne wrote about events in the Secret Annex, but also about her feelings and thoughts. In addition, she wrote short stories, started on a novel and copied passages from the books she read in her ‘Book of Beautiful Sentences’. Writing helped her pass the time. 
Nevertheless, the Nazi Party's voter base consisted mainly of farmers and the middle class, including groups such as Weimar government officials, school teachers, doctors, clerks, self-employed businessmen, salesmen, retired officers, engineers, and students.[176] Their demands included lower taxes, higher prices for food, restrictions on department stores and consumer co-operatives, and reductions in social services and wages.[177] The need to maintain the support of these groups made it difficult for the Nazis to appeal to the working class, since the working class often had opposite demands.[177]
The Nazis used propaganda to promulgate the concept of Rassenschande ("race defilement") to justify the need for racial laws.[214] In September 1935, the Nuremberg Laws were enacted. These laws initially prohibited sexual relations and marriages between Aryans and Jews and were later extended to include "Gypsies, Negroes or their bastard offspring".[215] The law also forbade the employment of German women under the age of 45 as domestic servants in Jewish households.[216] The Reich Citizenship Law stated that only those of "German or related blood" could be citizens.[217] Thus Jews and other non-Aryans were stripped of their German citizenship. The law also permitted the Nazis to deny citizenship to anyone who was not supportive enough of the regime.[217] A supplementary decree issued in November defined as Jewish anyone with three Jewish grandparents, or two grandparents if the Jewish faith was followed.[218]
If it isn’t already clear, we are not reliving the thirties, and Trump is not Hitler. One of the journalists whom Schneidermann admires is Edgar Ansel Mowrer, a correspondent for the Chicago Daily News who had already been in Berlin for a decade when Hitler became Chancellor of Germany, in January, 1933. Mowrer’s work strongly captures the widespread anti-Semitic violence of the years that preceded Hitler: Jews were assaulted in public, Jewish students were beaten up by classmates. And all German political parties had armed militias that confronted one another frequently—and violently—in the streets; hundreds of people were killed during the 1932 election campaign. This was the context in which Hitler was elected. After Mowrer published a book on this material, the same month as Hitler’s inauguration, he was expelled from Germany.
It was three o'clock in the afternoon when we arrived; nine hours later, without food or drink, we were brought to the so-called reception barrack. At its door stood an S. S. man who tried to hasten the entrance of each novice by a kick in the seat. Inside, inmates used as office help were sitting at long rows of typewriters, and they took down our personal data with stiff military posture—a difficult job for those who hadn't served in the army. To them we had to give account. Then we had to hand over all our valuables: rings, watches, chains, tie pins, and our wallets and purses with contents. They were exactly registered and kept in paper bags signed by us. (In contrast to reliable reports from other camps, we were given back our money to the last cent and all valuables on the day of our release.)

The lead editors of the Encyclopedia of Camps and Ghettos, 1933–1945 of the United States Holocaust Memorial Museum, Geoffrey Megargee and Martin Dean, cataloged some 42,500 Nazi ghettos and camps throughout Europe, spanning German-controlled areas from France to Russia and Germany itself, operating from 1933 to 1945. They estimate that 15 million to 20 million people died or were imprisoned in the sites.[36]
Under this extermination program, known to S.S. bureaucrats by the code Action 14f13, some sixty-five hundred prisoners were killed in the course of a year. By early 1942, it had become obsolete, as the scale of death in the camps increased. Now the killing of weak and sick prisoners was carried out by guards or camp doctors, sometimes in gas chambers built on site. Those who were still able to work were increasingly auctioned off to private industry for use as slave labor, in the many subcamps that began to spring up around the main K.L. At Ravensbrück, the Siemens corporation established a factory where six hundred women worked twelve-hour shifts building electrical components. The work was brutally demanding, especially for women who were sick, starved, and exhausted. Helm writes that “Siemens women suffered severely from boils, swollen legs, diarrhea and TB,” and also from an epidemic of nervous twitching. When a worker reached the end of her usefulness, she was sent back to the camp, most likely to be killed. It was in this phase of the camp’s life that sights like the one Loulou Le Porz saw at Ravensbrück—a truck full of prisoners’ corpses—became commonplace.

Of course, there were aspects of Nazism which were reactionary, such as their attitude toward the role of women in society, which was completely traditionalist,[284] calling for the return of women to the home as wives, mothers and homemakers, although ironically this ideological policy was undermined in reality by the growing labor shortages and need for more workers. The number of women in the workplace climbed throughout the period of Nazi control of Germany, from 4.24 million in 1933 to 4.52 million in 1936 and 5.2 million in 1938, numbers that far exceeded those of the Weimar Republic.[285]

Very heavy strategic bombing by the Allies targeted refineries producing synthetic oil and gasoline, as well as the German transportation system, especially rail yards and canals.[287] The armaments industry began to break down by September 1944. By November, fuel coal was no longer reaching its destinations and the production of new armaments was no longer possible.[288] Overy argues that the bombing strained the German war economy and forced it to divert up to one-fourth of its manpower and industry into anti-aircraft resources, which very likely shortened the war.[289]
In 1931, Himmler organised an SS intelligence service which became known as the Sicherheitsdienst (SD; Security Service) under his deputy, Heydrich.[246] This organisation was tasked with locating and arresting communists and other political opponents.[247][248] Himmler established the beginnings of a parallel economy under the auspices of the SS Economy and Administration Head Office. This holding company owned housing corporations, factories, and publishing houses.[249][250]
I do not understand, however, the attitude of Hitler and his followers in this matter. To atone for the Paris murder, the Nazis imposed a collective punishment upon all German subjects of Jewish origin. First they organized a 'spontaneous' outburst of popular rage on the eve of November 10, 1938, throughout Germany at almost the same hour, and everywhere by the same methods. Abuses and tortures, even manslaughter, destruction of Jewish shops and apartments, arson of synagogues with gasoline brought for the purpose—such was the program.
Some Auschwitz prisoners were subjected to inhumane medical experimentation. The chief perpetrator of this barbaric research was Josef Mengele (1911-79), a German physician who began working at Auschwitz in 1943. Mengele, who came to be known as the “Angel of Death,” performed a range of experiments on detainees. For example, in an effort to study eye color, he injected serum into the eyeballs of dozens of children, causing them excruciating pain. He also injected chloroform into the hearts of twins, to determine if both siblings would die at the same time and in the same manner.

On 23 March, the parliament passed the Enabling Act of 1933, which gave the cabinet the right to enact laws without the consent of parliament. In effect, this gave Hitler dictatorial powers. Now possessing virtually absolute power, the Nazis established totalitarian control as they abolished labour unions and other political parties and imprisoned their political opponents, first at wilde Lager, improvised camps, then in concentration camps. Nazi Germany had been established, yet the Reichswehr remained impartial. Nazi power over Germany remained virtual, not absolute.
In the decades since its liberation, Auschwitz has become a primary symbol of the Holocaust. Historian Timothy D. Snyder attributes this to the camp's high death toll and "unusual combination of an industrial camp complex and a killing facility", which left behind far more witnesses than single-purpose killing facilities such as Chełmno or Treblinka.[272] In 2005 the United Nations General Assembly designated 27 January, the date of the camp's liberation, as International Holocaust Remembrance Day.[273] Helmut Schmidt visited the site in November 1977, the first West German chancellor to do so, followed by his successor, Helmut Kohl, in November 1989.[274] In a written statement on the fiftieth anniversary of the liberation, Kohl described Auschwitz as the "darkest and most horrific chapter of German history".[275]

Nazi ideology advocated excluding women from political involvement and confining them to the spheres of "Kinder, Küche, Kirche" (Children, Kitchen, Church).[181] Many women enthusiastically supported the regime, but formed their own internal hierarchies.[182] Hitler's own opinion on the matter of women in Nazi Germany was that while other eras of German history had experienced the development and liberation of the female mind, the National Socialist goal was essentially singular in that it wished for them to produce a child.[183] Based on this theme, Hitler once remarked about women that "with every child that she brings into the world, she fights her battle for the nation. The man stands up for the Volk, exactly as the woman stands up for the family".[184] Proto-natalist programs in Nazi Germany offered favourable loans and grants to newlyweds and encouraged them to give birth to offspring by providing them with additional incentives.[185] Contraception was discouraged for racially valuable women in Nazi Germany and abortion was forbidden by strict legal mandates, including prison sentences for women who sought them as well as prison sentences for doctors who performed them, whereas abortion for racially "undesirable" persons was encouraged.[186][187]
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]
When it comes to documenting the Nazis’ murder of Jews, Schneidermann describes the Times’ coverage as fragmentary, incremental, and buried in “dry” briefings on interior pages. June 16, 1942, page 6: a short piece noting that sixty thousand Jews in Vilnius had been murdered. June 30, 1942, page 7: a press conference given by a Polish government official in exile concludes that around a sixth of the European Jewish population of six to seven million has been annihilated. Schneidermann tries to grapple with the possible explanations—the incredulity of the reporters and editors, the banalization of so much recurring death. (Although, on a much different scale, the dilemma is not entirely foreign to Schneidermann’s audience: twenty-three hundred Europe-bound migrants drowned in the Mediterranean Sea last year, and the coverage of it in mainstream publications has been sporadic at best.)
We lived in Bótrágy, a very small, mostly poor town in Czechoslovakia with a population of approximately 1,000 mainly farming families, including about 10 Jewish families. The town was a typical low-income community with a tailor, a shoemaker, a grocery store, where people struggled to get by, but where everyone knew each other and there was easy communication between the neighbours, though that didn’t mean we were equal.
Large segments of the Nazi Party, particularly among the members of the Sturmabteilung (SA), were committed to the party's official socialist, revolutionary and anti-capitalist positions and expected both a social and an economic revolution when the party gained power in 1933.[43] In the period immediately before the Nazi seizure of power, there were even Social Democrats and Communists who switched sides and became known as "Beefsteak Nazis": brown on the outside and red inside.[44] The leader of the SA, Ernst Röhm, pushed for a "second revolution" (the "first revolution" being the Nazis' seizure of power) that would enact socialist policies. Furthermore, Röhm desired that the SA absorb the much smaller German Army into its ranks under his leadership.[43] Once the Nazis achieved power, Röhm's SA was directed by Hitler to violently suppress the parties of the left, but they also began attacks against individuals deemed to be associated with conservative reaction.[45] Hitler saw Röhm's independent actions as violating and possibly threatening his leadership, as well as jeopardising the regime by alienating the conservative President Paul von Hindenburg and the conservative-oriented German Army.[46] This resulted in Hitler purging Röhm and other radical members of the SA in 1934, in what came to be known as the Night of the Long Knives.[46]
The metaphor of war encouraged the inhumanity of the S.S. officers, which they called toughness; licensed physical violence against prisoners; and accounted for the military discipline that made everyday life in the K.L. unbearable. Particularly hated was the roll call, or Appell, which forced inmates to wake before dawn and stand outside, in all weather, to be counted and recounted. The process could go on for hours, Wachsmann writes, during which the S.S. guards were constantly on the move, punishing “infractions such as poor posture and dirty shoes.”
That is why, since its creation in 2009, the foundation that raises money to maintain the site of Auschwitz-Birkenau has had a guiding philosophy: “To preserve authenticity.” The idea is to keep the place intact, exactly as it was when the Nazis retreated before the Soviet Army arrived in January 1945 to liberate the camp, an event that resonates on Holocaust Remembrance Day, on Thursday.
There are many self-reflective passages where Anne laments being picked on by the adults in the annex, wondering if she will live up to the expectations they have for her, hoping she can reach her goals. There is a thread of hope apparent even in her most depressing writings. I think these are the parts I think teens find most relate-able because all teens want to achieve things, please their parents, and find hope in their moments of despair.
The extermination camp Treblinka was working from July 1942 to November 1943. In August 1943 an uprising destroyed many of the facilities. 900,000 Jews lost their lives in this camp.    Auschwitz-Birkenau, which also functioned as a concentration camp and a work camp, became the largest killing centre. It is estimated that between 1 and 2 million were killed in the extermination camp Auschwitz-Birkenau. The first gassing experiments, involving 250 Polish and 600 Soviet POW’s, were carried out as early as September 1941. The extermination camp was started up in March 1942 and ended its work in November 1944. 

When I met her at her house in London, Lasker-Wallfisch, 84, explained that she and her sister avoided the dreaded selection process because they went to Birkenau as convicts. “People shipped from prisons weren’t shipped in huge trainloads of Jews,” Lasker-Wallfisch said. “They were shipped as individuals, which was an advantage. It’s not worth turning the gas on for one Jew, I suppose.” Instead, Lasker-Wallfisch was stripped, guards shaved her head and an inmate tattooed her with an identification number (a practice unique to Auschwitz).

Hitler took a personal interest in architecture and worked closely with state architects Paul Troost and Albert Speer to create public buildings in a neoclassical style based on Roman architecture.[466][467] Speer constructed imposing structures such as the Nazi party rally grounds in Nuremberg and a new Reich Chancellery building in Berlin.[468] Hitler's plans for rebuilding Berlin included a gigantic dome based on the Pantheon in Rome and a triumphal arch more than double the height of the Arc de Triomphe in Paris. Neither structure was built.[469]
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.

Very heavy strategic bombing by the Allies targeted refineries producing synthetic oil and gasoline, as well as the German transportation system, especially rail yards and canals.[287] The armaments industry began to break down by September 1944.

On our arrival at Auschwitz they chased us off the cattle wagon, which stopped right in front of the gate with the sign Arbeit Macht Frei (Work Makes You Free). I thought I was entering a labour camp, but little did I know. They asked me my profession, and I said painter as I’d picked up the advice en route to say something practical and useful. If I’d said I’d just finished high school they’d have sent me straight to the gas chambers.
Annelies Marie Frank was born in Frankfurt on June 12, 1929 to Edith (née Holländer) and Otto Frank. The Frank family, which was affluent and socially active, had lived in the city since the seventeenth century. Otto and his two brothers served in the German army in World War I. In 1933, after the Nazi party came to power, the family moved to Amsterdam. For the first seven years, things were relatively quiet for the parents and their two daughters, Margot Betti (1926–1945) and her younger sister Anne, who attended the Montessori school until Germany invaded the Netherlands in May 1940.
In the Soviet Union by 1922 there were 23 concentration camps for the incarceration of persons accused of political offenses as well as criminal offenses. Many corrective labour camps were established in northern Russia and Siberia, especially during the First Five-Year Plan, 1928–32, when millions of rich peasants were driven from their farms under the collectivization program. The Stalinist purges of 1936–38 brought additional millions into the camps—said to be essentially institutions of slavery.
