More than 40 sub-camps, exploiting the prisoners as slave laborers, were also founded, mainly as various sorts of German industrial plants and farms, between 1942 and 1944. The largest of them was called Buna (Monowitz, with ten thousand prisoners) and was opened by the camp administration in 1942 on the grounds of the Buna-Werke synthetic rubber and fuel plant, six kilometers from the Auschwitz camp. The factory was built during the war by the German IG Farbenindustrie cartel, and the SS supplied prisoner labor. On November 1943, the Buna sub-camp became the seat of the commandant of the third part of the camp, Auschwitz III, to which some other Auschwitz sub-camps were subordinated.
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.
These people had a blue stamp in their registration cards, meaning that they were exempt from deportation. They were Jews who had British or American citizenship. The Nazis saw these Jews as ‘exchange Jews’, and they would attempt to exchange each one of them for five to 10 Germans; especially military prisoners of war. In fact, few exchanges ever occurred.
On 5 January 1919, Drexler created a new political party and proposed it should be named the "German Socialist Workers' Party", but Harrer objected to the term "socialist"; so the term was removed and the party was named the German Workers' Party (Deutsche Arbeiterpartei, DAP).[29] To ease concerns among potential middle-class supporters, Drexler made clear that unlike Marxists the party supported the middle-class and that its socialist policy was meant to give social welfare to German citizens deemed part of the Aryan race.[25] They became one of many völkisch movements that existed in Germany. Like other völkisch groups, the DAP advocated the belief that through profit-sharing instead of socialisation Germany should become a unified "people's community" (Volksgemeinschaft) rather than a society divided along class and party lines.[30] This ideology was explicitly antisemitic. As early as 1920, the party was raising money by selling a tobacco called Anti-Semit.[31]
After about an hour, I thanked him and stood up to leave. He handed me a white envelope. Inside was a slim memoir he published nearly 30 years ago. “My memory isn’t so good any more, you understand,” he said, shaking my hand and smiling. “But it’s all in there.” Later, I flipped to a page near the end. In October 1944, Stos was sent from Auschwitz to a series of camps deep in Germany. On May 8, 1945—the day the war in Europe ended—he was liberated by Russian soldiers. On the book’s second to last page is an undated black-and-white photo. It shows Stos with his children and grandchildren standing under the Arbeit Macht Frei sign.
In 1959, Otto Frank took legal action in Lübeck against Lothar Stielau, a school teacher and former Hitler Youth member who published a school paper that described the diary as "a forgery". The complaint was extended to include Heinrich Buddegerg, who wrote a letter in support of Stielau, which was published in a Lübeck newspaper. The court examined the diary in 1960 and authenticated the handwriting as matching that in letters known to have been written by Anne Frank. They declared the diary to be genuine. Stielau recanted his earlier statement, and Otto Frank did not pursue the case any further.[94]
This intellectual preparation would probably not have been sufficient for the growth of Nazism in Germany but for that country’s defeat in World War I. The defeat and the resulting disillusionment, pauperization, and frustration—particularly among the lower middle classes—paved the way for the success of the propaganda of Hitler and the Nazis. The Treaty of Versailles (1919), the formal settlement of World War I drafted without German participation, alienated many Germans with its imposition of harsh monetary and territorial reparations. The significant resentment expressed toward the peace treaty gave Hitler a starting point. Because German representatives (branded the “November criminals” by National Socialists) agreed to cease hostilities and did not unconditionally surrender in the armistice of November 11, 1918, there was a widespread feeling—particularly in the military—that Germany’s defeat had been orchestrated by diplomats at the Versailles meetings. From the beginning, Hitler’s propaganda of revenge for this “traitorous” act, through which the German people had been “stabbed in the back,” and his call for rearmament had strong appeal within military circles, which regarded the peace only as a temporary setback in Germany’s expansionist program. The ruinous inflation of the German currency in 1923 wiped out the savings of many middle-class households and led to further public alienation and dissatisfaction.
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.

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]
Auschwitz became one of the camps used for the mass extermination of Jews. In summer 1941, Heinrich Himmler gave orders to Auschwitz commander Rudolf Höß to build a centre at Auschwitz for the mass murder of Jews. In September 1941, the lethal effects of Zyklon B - a substance normally used for pest control - were first tested and verified there. Later, four large gas chambers were built at Birkenau, capable of killing up to six thousand people each day. The gas chambers were disguised as showers, meant to persuade the victims that these were disinfection measures which they had to undergo before they were sent to work in the camp.
The Nazi Terror Begins After Adolf Hitler became chancellor of Germany in January 1933, he moved quickly to turn Germany into a one-party dictatorship and to organize the police power necessary to enforce Nazi policies. He persuaded his Cabinet to declare a state of emergency and end individual freedoms, including freedom of press, speech, and assembly. Individuals lost the right to privacy, which meant that officials could read people's mail, listen in on telephone conversations, and search private homes without a warrant.

At the bottom of the K.L. hierarchy, even below the criminals, were the Jews. Today, the words “concentration camp” immediately summon up the idea of the Holocaust, the genocide of European Jews by the Nazis; and we tend to think of the camps as the primary sites of that genocide. In fact, as Wachsmann writes, as late as 1942 “Jews made up fewer than five thousand of the eighty thousand KL inmates.” There had been a temporary spike in the Jewish inmate population in November, 1938, after Kristallnacht, when the Nazis rounded up tens of thousands of Jewish men. But, for most of the camps’ first decade, Jewish prisoners had usually been sent there not for their religion, per se, but for specific offenses, such as political dissent or illicit sexual relations with an Aryan. Once there, however, they found themselves subject to special torments, ranging from running a gantlet of truncheons to heavy labor, like rock-breaking. As the chief enemies in the Nazi imagination, Jews were also the natural targets for spontaneous S.S. violence—blows, kicks, attacks by savage dogs.

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.
Although Nazism is often seen as a reactionary movement, it did not seek a return of Germany to the pre-Weimar monarchy, but instead looked much further back to a mythic halcyon Germany which never existed. It has also been seen – as it was by the German-American scholar Franz Leopold Neumann – as the result of a crisis of capitalism which manifested as a "totalitarian monopoly capitalism". In this view Nazism is a mass movement of the middle class which was in opposition to a mass movement of workers in socialism and its extreme form, Communism.[277] Historian Karl Dietrich Bracher, however, argues that,

After 1942, many small subcamps were set up near factories to provide forced labor. IG Farben established a synthetic rubber plant in 1942 at Monowitz concentration camp (Auschwitz III); other camps were set up next to airplane factories, coal mines and rocket propellant plants. Conditions were brutal and prisoners were often sent to the gas chambers or killed on site if they did not work quickly enough.
