When Hitler and the Nazis came to power in 1933, they instituted a series of measures aimed at persecuting Germany’s Jewish citizens. By late 1938, Jews were banned from most public places in Germany. During the war, the Nazis’ anti-Jewish campaigns increased in scale and ferocity. In the invasion and occupation of Poland, German troops shot thousands of Polish Jews, confined many to ghettoes where they starved to death and began sending others to death camps in various parts of Poland, where they were either killed immediately or forced into slave labor. In 1941, when Germany invaded the Soviet Union, Nazi death squads machine-gunned tens of thousands of Jews in the western regions of Soviet Russia.

Those unable to work – the old, women and children – were immediately sent to the gas chambers or shot in the "camp hospital". Even those able to work ended up in the gas chamber sooner or later, or they fell victim to random shooting actions within a few months, when they had been worn out by the tough work. That is, if they had not died already. Those able to work for instance helped carry the bodies to the crematoria or search the bodies for valuables.

Himmler visited Auschwitz in March 1941 and commanded its enlargement to hold 30,000 prisoners. Himmler also ordered the construction of a second camp for 100,000 inmates on the site of the village of Brzezinka (Birkenau), roughly 4 km from the main camp. This massive camp was intended to be filled with captured Russian POWs who would provide the slave labor to build the SS 'utopia' in Upper Silesia. The chemical giant I G Farben expressed an interest in utilizing this labor force, too. Extensive construction work began in October 1941, under terrible conditions and with massive loss of life. About 10,000 Russian POWs died in the process.
Army photographers and cameramen, along with leading war correspondents, recorded the aftermath of Bergen-Belsen's liberation. This photograph was taken by Sergeant Harry Oakes of the Army Film and Photographic Unit. It shows prisoners sitting by a wire fence which divided two sections of the camp. They are eating their first meal after the liberation of the camp.
The fortified walls, barbed wire, railway sidings, platforms, barracks, gallows, gas chambers and crematoria at Auschwitz Birkenau show clearly how the Holocaust, as well as the Nazi German policy of mass murder and forced labour took place. The collections at the site preserve the evidence of those who were premeditatedly murdered, as well as presenting the systematic mechanism by which this was done. The personal items in the collections are testimony to the lives of the victims before they were brought to the extermination camps, as well as to the cynical use of their possessions and remains. The site and its landscape have high levels of authenticity and integrity since the original evidence has been carefully conserved without any unnecessary restoration.
Gradowski was not poetic; he was prophetic. He did not gaze into this inferno and ask why. He knew. Aware of both the long recurring arc of destruction in Jewish history, and of the universal fact of cruelty’s origins in feelings of worthlessness, he writes: “This fire was ignited long ago by the barbarians and murderers of the world, who had hoped to drive darkness from their brutal lives with its light.”
Towards the war's end, in an effort to remove all traces of the crimes they had committed, the SS began to dismantle and raze the gas chambers, crematoria, and other buildings, as well as burning documents. Prisoners capable of moving were forced into death marches to other remaining areas of the Third Reich. Those who remained behind in the camp were liberated by Red Army soldiers on 27 January 1945. An estimated 1.3 million Jews, Poles, Soviet POWs, Roma, homosexuals, and Jehovah's Witnesses had been murdered within the camps by the time of liberation.

…party, Hitler joined a German nationalist group that took the name of National Socialist German Workers’ Party (Nationalsozialistische Deutsche Arbeiterpartei), nicknamed “Nazi,” a truncation of Nationalsozialistische. Its policies included anti-Semitism and fierce opposition to the Treaty of Versailles. After his abortive Munich coup in 1923, Hitler was sentenced to five…
Nazism emphasized German nationalism, including both irredentism and expansionism. Nazism held racial theories based upon a belief in the existence of an Aryan master race that was superior to all other races. The Nazis emphasised the existence of racial conflict between the Aryan race and others—particularly Jews, whom the Nazis viewed as a mixed race that had infiltrated multiple societies and was responsible for exploitation and repression of the Aryan race. The Nazis also categorised Slavs as Untermensch (sub-human).[129]
I recall the time in Auschwitz as single moments, short encounters, smells. We tried to distract ourselves from the reality of it by trying to recall our home lives in what turned into a game of momentary escapism. Quietly, the children would huddle together and ask each other: “What will you have for breakfast?” And I remember saying: “Maybe an egg or a piece of bread and butter,” and tried to conjure up memories of home.
Remarkably, there were instances of individual resistance and collective efforts at fighting back inside Auschwitz. Poles, Communists and other national groups established networks in the main camp. A few Jews escaped from Birkenau, and there were recorded assaults on Nazi guards even at the entrance to the gas chambers. The 'Sonderkommando' revolt in October 1944 was the extraordinary example of physical resistance.
Another method was the use of gassing trucks. In Chemno gassing trucks were used, where Jews, after being driven into the trucks, were suffocated by the exhaust fumes that were led into them in the truck. A third method was mass shooting of Jews and other groups (Soviet POW’s, Poles, etc.). In Majdanek, on 3-4 November 1943, between 17,000 and 18,000 Jews were killed in one day as part of a mass shooting. The event was called Erntefest (‘harvest feast’) and included similar actions all around the Lublin District. More than 40,000 Jews died as a result.

Camp commandant Rudolf Höss was arrested by the British at a farm near Flensburg, Germany, on 11 March 1946, where he had been working under the pseudonym Franz Lang.[263] He was imprisoned in Heide, then transferred to Minden for interrogation, part of the British occupation zone. From there he was taken to Nuremberg to testify for the defense in the trial of SS-Obergruppenführer Ernst Kaltenbrunner. Höss was straightforward about his own role in the mass murder and said he had followed the orders of Heinrich Himmler.[264][g] Extradited to Poland on 25 May 1946,[265] he wrote his memoirs in custody, first published in Polish in 1951 then in German in 1958 as Kommandant in Auschwitz.[266] His trial before the Supreme National Tribunal in Warsaw opened on 11 March 1947; he was sentenced to death on 2 April and hanged in Auschwitz I, near crematorium I, on 16 April.[267]
In most of the concentration camps, the Nazi SS either installed or had plans to install gas chambers to assist in their daily business of killing prisoners who were too weak or sick to work. Gas chambers were also to kill small targeted groups of individuals whom the Nazis wanted to eliminate (Polish resistance fighters, Soviet POWs, etc.). This was the purpose of the installation of gas chambers at Mauthausen, Sachsenhausen, Stutthof, Auschwitz I, Ravensbrück, Lublin/Majdanek, etc.

Prior to the Nazi ascension to power, Hitler often blamed moral degradation on Rassenschande ("racial defilement"), a way to assure his followers of his continuing antisemitism, which had been toned down for popular consumption.[96] Prior to the induction of the Nuremberg Race Laws in 1935 by the Nazis, many German nationalists such as Roland Freisler strongly supported laws to ban Rassenschande between Aryans and Jews as racial treason.[96] Even before the laws were officially passed, the Nazis banned sexual relations and marriages between party members and Jews.[97] Party members found guilty of Rassenschande were severely punished; some party members were even sentenced to death.[98]

A neighbor and acquaintance of the Frank girls later said that Anne was extremely talented but also harsh, rebellious and sharp-tongued, while her parents were easygoing people and Margot was an excellent and much-liked pupil. Yet the diary shows the world a sensitive and talented Anne while depicting her mother and sister as self-righteous complainers. Another childhood friend of Anne’s gave similar accounts of the family’s personalities, describing Anne as acquisitive, self-centered and very sexual. A series of accounts, interviews and biographies that appeared mainly in the 1980s and 1990s describe Anne and the other fugitives in a more complex manner than the diary and its successors.
Fascism was a major influence on Nazism. The seizure of power by Italian Fascist leader Benito Mussolini in the March on Rome in 1922 drew admiration by Hitler, who less than a month later had begun to model himself and the Nazi Party upon Mussolini and the Fascists.[121] Hitler presented the Nazis as a form of German fascism.[122][123] In November 1923, the Nazis attempted a "March on Berlin" modelled after the March on Rome, which resulted in the failed Beer Hall Putsch in Munich.[124]

SS formations committed many war crimes against civilians and allied servicemen.[238] From 1935 onward, the SS spearheaded the persecution of Jews, who were rounded up into ghettos and concentration camps.[239] With the outbreak of World War II, the SS Einsatzgruppen units followed the army into Poland and the Soviet Union, where from 1941 to 1945 they killed more than two million people, including 1.3 million Jews.[240] A third of the Einsatzgruppen members were recruited from Waffen-SS personnel.[241][242] The SS-Totenkopfverbände (death's head units) ran the concentration camps and extermination camps, where millions more were killed.[243][244] Up to 60,000 Waffen-SS men served in the camps.[245]

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.

If Godwin has a law clerk, she is working overtime this week. I refer to the truism Godwin’s Law: that all arguments eventually end with Hitler and the Holocaust. Everyone, it seems, is hurling comparisons between the American detention centers housing refugee children at the Mexican border and Nazi concentration camps. Former CIA director Michael Hayden tweeted an image of Auschwitz-Birkenau with the message, “Other governments have separated mothers and children.”
The Nazi regime promoted a liberal code of conduct regarding sexual matters and was sympathetic to women who bore children out of wedlock.[382] Promiscuity increased as the war progressed, with unmarried soldiers often intimately involved with several women simultaneously. Soldier's wives were frequently involved in extramarital relationships. Sex was sometimes used as a commodity to obtain better work from a foreign labourer.[383] Pamphlets enjoined German women to avoid sexual relations with foreign workers as a danger to their blood.[384]
Auschwitz I, a former Polish army barracks, was the main camp (Stammlager) and administrative headquarters of the camp complex. Intending to use it to house political prisoners, Reichsführer-SS Heinrich Himmler, head of the Schutzstaffel (SS), approved the site in April 1940 on the recommendation of SS-Obersturmbannführer (lieutenant colonel) Rudolf Höss, then of the Concentration Camps Inspectorate. Höss oversaw the development of the camp and served as its first commandant, with SS-Obersturmführer (senior lieutenant) Josef Kramer as his deputy.[21] Around 1,000 m long and 400 m wide,[22] Auschwitz I consisted of 20 brick buildings, six of them two-story; a second story was added to the others in 1943 and eight new blocks were built.[23] The camp housed the SS barracks and by 1943 held 30,000 inmates.[22] The first 30 prisoners arrived on 20 May 1940 after being transported from the Sachsenhausen concentration camp in Oranienburg, Germany. Convicted German criminals (Berufsverbrecher), the men were known as "greens" after the green triangles they were required to wear on their prison clothing. Brought to the camp as functionaries, this group did much to establish the sadism of early camp life, which was directed particularly at Polish inmates, until the political prisoners began to take over their roles.[4]
Because the diary ends with the discovery of the hiding place and the deportation of its occupants to Auschwitz and from there to Bergen-Belsen, there are no harsh descriptions of the sort written by other young Jewish men and women, especially from Eastern Europe: there are no ghettos or camps, no starvation or loss of family members in aktions. The Germans are mentioned in the diary with hatred, called “Those vile people … the cruelest monsters ever to stalk the earth,” as Anne wrote on November 19, 1942. The attic’s occupants learned about their deeds, including the camps and gas chambers, from the BBC radio broadcasts, but they do not occupy a significant place in the diary, which centers mainly on the world of the attic’s inhabitants and their daily lives and Anne’s young, rich inner world. Readers are not asked to cope with the atrocity itself, and so the reading is less distressing. They do and do not read about the Holocaust at one and the same time.
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.”
The Nazis argued that free market capitalism damages nations due to international finance and the worldwide economic dominance of disloyal big business, which they considered to be the product of Jewish influences.[246] Nazi propaganda posters in working class districts emphasised anti-capitalism, such as one that said: "The maintenance of a rotten industrial system has nothing to do with nationalism. I can love Germany and hate capitalism".[261]

Hitler was not influenced by the United States alone. “Let’s learn from the English,” Hitler said repeatedly, “who, with two hundred and fifty thousand men in all, including fifty thousand soldiers, govern four hundred million Indians.” According to multiple sources, Hitler was also fascinated by Islam, which he saw as a muscular, militant religion in contrast to the meek faith of suffering that was Christianity—despite the fact that Arabs were Semites, and that non-Arab Muslims were considered racially inferior. Even closer to Hitler’s mind was Mustafa Kemal Pasha, or Atatürk, the founder of modern Turkey, who had resisted the Versailles Treaty and whose regime’s genocide of the Armenians was an early example of exterminationist policy.

The Reich Forestry Office under Göring enforced regulations that required foresters to plant a variety of trees to ensure suitable habitat for wildlife, and a new Reich Animal Protection Act became law in 1933.[402] The regime enacted the Reich Nature Protection Act in 1935 to protect the natural landscape from excessive economic development. It allowed for the expropriation of privately owned land to create nature preserves and aided in long-range planning.[403] Perfunctory efforts were made to curb air pollution, but little enforcement of existing legislation was undertaken once the war began.[404]
Early camps, usually without proper infrastructure, sprang up everywhere in Germany after Hitler became Chancellor in January 1933: rising "like mushrooms after the rain", Himmler recollected.[51] These early camps, also called "Wild camps" because some were set up with little supervision from higher authorities, were overseen by Nazi paramilitaries, by political-police forces, and sometimes by local police authorities. They utilized any lockable larger space, for example: engine rooms, brewery floors, storage facilities, cellars, etc.[52]
