Spengler's definition of socialism did not advocate a change to property relations.[110] He denounced Marxism for seeking to train the proletariat to "expropriate the expropriator", the capitalist and then to let them live a life of leisure on this expropriation.[115] He claimed that "Marxism is the capitalism of the working class" and not true socialism.[115] According to Spengler, true socialism would be in the form of corporatism, stating that "local corporate bodies organised according to the importance of each occupation to the people as a whole; higher representation in stages up to a supreme council of the state; mandates revocable at any time; no organised parties, no professional politicians, no periodic elections".[116]
In the early years of the regime, Germany was without allies, and its military was drastically weakened by the Versailles Treaty. France, Poland, Italy, and the Soviet Union each had reasons to object to Hitler's rise to power. Poland suggested to France that the two nations engage in a preventive war against Germany in March 1933. Fascist Italy objected to German claims in the Balkans and on Austria, which Benito Mussolini considered to be in Italy's sphere of influence.[52]
My father surveyed the scene from the train and could see prisoners, uniforms and barracks so we immediately thought it was a work camp, and that was reassuring – if we can work, it can’t be such a dreadful place. We had heard about the stories in Poland of lots of mass shootings of Jews or people being taken into the forest and shot, so it was a relief to see out the window that there was actually a system. Even though we were victims of discrimination at that stage that’s all it was, as we had no clue then that this was a very carefully orchestrated plan of genocide. We could not have imagined that they would kill little children, until we realised that killing children was their primary goal to prevent any new generations. Because desperate people will always look to find some sign of hope, we thought to ourselves even if we have to work, at least we’ll see each other occasionally.
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.

When we think of the crimes of Nazi doctors, what comes to mind are their cruel and sometimes fatal experiments… Yet when we turn to the Nazi doctors’ role in Auschwitz, it was not the experiments that were most significant. Rather, it was his participation in the killing process—indeed his supervision of Auschwitz mass murder from beginning to end. 1

Soon afterwards, the gas chambers and crematoria were destroyed on Himmler's orders, since the regime wanted to hide the traces of its murdering machine ahead of the advancing Red Army. As Soviet troops came near to the camp in January 1945, it was hurriedly evacuated and 58 000 prisoners were driven out on a death march, during which most were killed. On the 27th of January 1945, the Red Army entered the camp (link in Czech). They found 7 650 exhausted and starving prisoners and a number of pieces of evidence of crimes that the Nazis had not had time to destroy. In the camp stores they found almost eight tonnes of human hair and over a million men's suits and women's dresses.
The swastika has come to represent the Nazis because of it's use on the Nazi flag. The Nazi flag, created by Hitler, has a red background, and a white circle with a black right-facing swastika in the middle. But the swastika predates the Nazis. The earliest consistent use of swastika motifs on record date back to the Stone Age. The swastika has been used as a religious symbol in many different religions. The word swastika comes from a Sanskrit word (svastika) meaning any lucky or auspicious object, and in particular a mark made on persons and things to denote good luck. Although, because of it's association with the Nazis, public showing of the swastika and other Nazi symbols, in Germany, is illegal, except for scholarly or religious reasons.
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.
On 3 September 1944,[a] the group was deported on what would be the last transport from Westerbork to the Auschwitz concentration camp and arrived after a three-day journey. On the same train was Bloeme Evers-Emden, an Amsterdam native who had befriended Margot and Anne in the Jewish Lyceum in 1941.[48] Bloeme saw Anne, Margot, and their mother regularly in Auschwitz,[49] and was interviewed for her remembrances of the Frank women in Auschwitz in the television documentary The Last Seven Months of Anne Frank (1988) by Dutch filmmaker Willy Lindwer[50] and the BBC documentary Anne Frank Remembered (1995).[51]

In June 2016, the Auschwitz-Birkenau museum in the Polish town of Oswiecim re-discovered over 16,000 personal items belonging to victims of Auschwitz-Birkenau that had been lost in 1968. The items were originally discovered in 1967 by archaeologists excavating the concentration camp site, and were placed in 48 cardboard boxes in the Polish Academy of Sciences in Warsaw before being lost due to an anti-Semitic communist regime coming to power in 1968.
Nazism attempted to reconcile conservative, nationalist ideology with a socially radical doctrine. In so doing, it became a profoundly revolutionary movement—albeit a largely negative one. Rejecting rationalism, liberalism, democracy, the rule of law, human rights, and all movements of international cooperation and peace, it stressed instinct, the subordination of the individual to the state, and the necessity of blind and unswerving obedience to leaders appointed from above. It also emphasized the inequality of men and races and the right of the strong to rule the weak; sought to purge or suppress competing political, religious, and social institutions; advanced an ethic of hardness and ferocity; and partly destroyed class distinctions by drawing into the movement misfits and failures from all social classes. Although socialism was traditionally an internationalist creed, the radical wing of Nazism knew that a mass base existed for policies that were simultaneously anticapitalist and nationalist. However, after Hitler secured power, this radical strain was eliminated.
Heinrich Himmler's Schutzstaffel (SS) took full control of the police and the concentration camps throughout Germany in 1934–35.[5] Himmler expanded the role of the camps to hold so-called "racially undesirable elements", such as Jews, Gypsies/Romanis/Sintis, Serbs, Poles, disabled people, and criminals.[6][7][8] The number of people in the camps, which had fallen to 7,500, grew again to 21,000 by the start of World War II[9] and peaked at 715,000 in January 1945.[10]
