Le Porz’s remark was prophetic. The true extent of Nazi barbarity became known to the world in part through the documentary films made by Allied forces after the liberation of other German camps. There have been many atrocities committed before and since, yet to this day, thanks to those images, the Nazi concentration camp stands as the ultimate symbol of evil. The very names of the camps—Dachau, Bergen-Belsen, Buchenwald, Auschwitz—have the sound of a malevolent incantation. They have ceased to be ordinary place names—Buchenwald, after all, means simply “beech wood”—and become portals to a terrible other dimension.

In Auschwitz and Majdanek, which had the role of both being a working and an extermination camp, Jews were divided upon arrival into those capable of working ands those not. The last group was sent directly to the gas chambers, whereas those able to work had to work themselves to death in SS’s industries – or they were executed when they worn down. In Auschwitz, the Jews worked in the so-called Monowitz working camp (Auschwitz III) in factories, or they were hired out to private businesses such as the chemical corporation I.G. Farben or the SS’s own factories.

Within this framework, "racially inferior" peoples, such as Jews and Gypsies, would be eliminated from the region. Nazi foreign policy aimed from the beginning to wage a war of annihilation against the Soviet Union, and the peacetime years of the Nazi regime were spent preparing the German people for war. In the context of this ideological war, the Nazis planned and implemented the Holocaust, the mass murder of the Jews, who were considered the primary "racial" enemy.

The first “bunker,” with two sealed rooms, operated from January 1942 to the end of that year. The second, with four air tight rooms, became redundant in the spring of 1943, but remained standing and was used again in the autumn of 1944 when extra “capacity” was needed for the murder of Hungarian Jews and the liquidation of the ghettos. The second measured about 1.134 square feet. The victims murdered in the “bunkers” were first obliged to undress in temporary wooden barracks erected nearby. Their bodies were taken out of the gas chambers and pushed to pits where they were burned in the open.

The Auschwitz concentration camp (Konzentrationslager Auschwitz) was a complex of over 40 concentration and extermination camps built and operated by Nazi Germany in occupied Poland during World War II and the Holocaust. It consisted of Auschwitz I, the main camp (Stammlager) and administrative headquarters, in Oświęcim; Auschwitz II–Birkenau, a combined concentration/extermination camp three kilometers away in Brzezinka; Auschwitz III–Monowitz, a labor camp seven kilometers from Auschwitz I, set up to staff an IG Farben synthetic-rubber factory; and dozens of other subcamps.[2]
And it means deploying conservators to preserve an inventory that includes more than a ton of human hair; 110,000 shoes; 3,800 suitcases; 470 prostheses and orthopedic braces; more than 88 pounds of eyeglasses; hundreds of empty canisters of Zyklon B poison pellets; patented metal piping and showerheads for the gas chambers; hundreds of hairbrushes and toothbrushes; 379 striped uniforms; 246 prayer shawls; more than 12,000 pots and pans carried by Jews who believed that they were simply bound for resettlement; and some 750 feet of SS documents — hygiene records, telegrams, architectural blueprints and other evidence of the bureaucracy of genocide — as well as thousands of memoirs by survivors.
Before long, Anne felt right at home in the Netherlands. She learned the language, made new friends and went to a Dutch school near her home. Her father worked hard to get his business off the ground, but it was not easy.  Otto also tried to set up a company in England, but the plan fell through. Things looked up when he started selling herbs and spices in addition to the pectin.
In January 1923, France occupied the Ruhr industrial region as a result of Germany's failure to meet its reparations payments. This led to economic chaos, the resignation of Wilhelm Cuno's government and an attempt by the German Communist Party (KPD) to stage a revolution. The reaction to these events was an upsurge of nationalist sentiment. Nazi Party membership grew sharply to about 20,000.[65] By November, Hitler had decided that the time was right for an attempt to seize power in Munich, in the hope that the Reichswehr (the post-war German military) would mutiny against the Berlin government and join his revolt. In this, he was influenced by former General Erich Ludendorff, who had become a supporter—though not a member—of the Nazis.
"Dr. Mengele had always been more interested in Tibi. I am not sure why - perhaps because he was the older twin. Mengele made several operations on Tibi. One surgery on his spine left my brother paralyzed. He could not walk anymore. Then they took out his sexual organs. After the fourth operation, I did not see Tibi anymore. I cannot tell you how I felt. It is impossible to put into words how I felt. They had taken away my father, my mother, my two older brothers - and now, my twin ..."
In 2018 the Polish government passed an amendment to its Act on the Institute of National Remembrance, making it a criminal offence to make false suggestions of Polish complicity in the Holocaust, which would include referring to Auschwitz and other camps as "Polish death camps".[304] After discussions with Israel's prime minister, amid international concern that the law would stifle research, the Polish government adjusted the amendment so that anyone falsely accusing Poland of complicity would be guilty only of a civil offence.[305]
The conservators have an easy camaraderie, but sometimes their task can become too much to bear. “Working with shoes probably is one of the most difficult parts of working here,” Ms. Banas-Maciaszczyk said. Everyone here has emotional moments. For her, it was a day when she was cleaning a little girl’s wooden sandal. She could see the small footprint inside. “This is something hard to describe,” she said. From 1940 to 1945, between 150,000 and 200,000 children died here.
Anne Frank's diary gives kids perspective and helps makes the tragic loss of life during WWII a tangible thing they can understand. The diary is so relate-able and reflects so many feelings that all teens have had, that she becomes three dimensional to them and no longer a just some person that died a long time ago. This sensitivity towards the loss of a life is what we need now in the times we live in.
When the 322nd Rifle Division of the Red Army liberated Auschwitz on 27 January 1945, the soldiers found 7,500 prisoners alive and over 600 corpses.[248][249] Auschwitz II-Birkenau was liberated at around 3:30 p.m., and the main camp (Auschwitz I) two hours later.[250] Items found by the Soviet soldiers included 370,000 men's suits, 837,000 women's garments, and 7.7 tonnes (8.5 short tons) of human hair.[248][249] Primo Levi described seeing the first four Russian soldiers on horseback approach the camp at Monowitz, where he had been in the sick bay. The soldiers threw "strangely embarrassed glances at the sprawling bodies, at the battered huts and at us few still alive ...":[251]
Between 1942 and 1944, the SS authorities at Auschwitz established 44 subcamps. Some of them were established within the officially designated “development” zone, including Budy, Rajsko, Tschechowitz, Harmense, and Babitz. Others, such as Blechhammer, Gleiwitz, Althammer, Fürstengrube, Laurahuette, and Eintrachthuette were located in Upper Silesia north and west of the Vistula River. Some subcamps, such as Freudenthal and Bruenn (Brno), were located in Moravia.

The cleansing of mouth and teeth was possible only after a two weeks' stay, when we had access to our money and could buy toothbrushes and tooth paste. The towel situation was deplorable. One towel a week was issued for each inmate, but there was no provision for keeping these towels separately. Not unnaturally skin infections, rashes, and boils were frequent. The barracks were heated by iron stoves, some of which were installed only after our admission to the camp, and we had enjoyed them for but a very short time when a sudden restriction denied us the use of them for one week. It was claimed that in one of the 'Jew barracks' the stove had been lighted at a time when it wasn't allowed.
Both Anne and Margot kept diaries while they were in hiding, although Margot’s diaries were never found. Living in hiding meant the group also lived in constant fear of being discovered—they were unable to go outside, had to be quiet, conceal any lights used after sunset, and keep the curtains and windows closed during the day. They lived in extremely close quarters with each other and were completely dependent on Miep Gies, Johannes Kleiman, Victor Kugler, and Bep Voskuijl, Otto’s employees, for food, supplies, and moral support. The group in hiding got news from the radio and from these helpers, who also brought books and gifts. Anne wrote, "They come upstairs every day and talk to the men about business and politics, to the women about food and wartime difficulties and to the children about books and newspapers. They put on their most cheerful expressions, bring flowers and gifts for birthdays and holidays and are always ready to do what they can."
Before he joined the Bavarian Army to fight in World War I, Hitler had lived a bohemian lifestyle as a petty street watercolour artist in Vienna and Munich and he maintained elements of this lifestyle later on, going to bed very late and rising in the afternoon, even after he became Chancellor and then Führer.[47] After the war, his battalion was absorbed by the Bavarian Soviet Republic from 1918 to 1919, where he was elected Deputy Battalion Representative. According to historian Thomas Weber, Hitler attended the funeral of communist Kurt Eisner (a German Jew), wearing a black mourning armband on one arm and a red communist armband on the other,[48] which he took as evidence that Hitler's political beliefs had not yet solidified.[48] In Mein Kampf, Hitler never mentioned any service with the Bavarian Soviet Republic and he stated that he became an antisemite in 1913 during his years in Vienna. This statement has been disputed by the contention that he was not an antisemite at that time,[49] even though it is well established that he read many antisemitic tracts and journals during time and admired Karl Lueger, the antisemitic mayor of Vienna.[50] Hitler altered his political views in response to the signing of the Treaty of Versailles in June 1919 and it was then that he became an antisemitic, German nationalist.[49]
In March 1941, Himmler ordered a second, larger complex to be built next to the original camp. It was called Auschwitz II - Birkenau. The camp at Birkenau was divided into subsections surrounded by electric fences with barbed wire. During 1943 and 1944 the BIIb section became the location of the „Terezín family camp“. At its summit, Birkenau had over 100 000 inmates. In March 1942, the Auschwitz III camp was set up at nearby Monowitz, also known as Buna Monowitz. German company I.G. Farben set up a synthetic rubber factory there, in which it used the prisoners' slave labour. Auschwitz also had a further 45 auxiliary camps, where prisoners were forced to engage in slave labour, mostly for German companies.
Nazi flags: The Nazi Party used a right-facing swastika as their symbol and the red and black colours were said to represent Blut und Boden ("blood and soil"). Another definition of the flag describes the colours as representing the ideology of National Socialism, the swastika representing the Aryan race and the Aryan nationalist agenda of the movement; white representing Aryan racial purity; and red representing the socialist agenda of the movement. Black, white and red were in fact the colours of the old North German Confederation flag (invented by Otto von Bismarck, based on the Prussian colours black and white and the red used by northern German states). In 1871, with the foundation of the German Reich the flag of the North German Confederation became the German Reichsflagge ("Reich flag"). Black, white and red became the colours of the nationalists through the following history (for example World War I and the Weimar Republic).
After the Night of the Long Knives, Hitler promoted Himmler and the SS, who then zealously suppressed homosexuality by saying: "We must exterminate these people root and branch ... the homosexual must be eliminated".[201] In 1936, Himmler established the "Reichszentrale zur Bekämpfung der Homosexualität und Abtreibung" ("Reich Central Office for the Combating of Homosexuality and Abortion").[202] The Nazi regime incarcerated some 100,000 homosexuals during the 1930s.[203] As concentration camp prisoners, homosexual men were forced to wear pink triangle badges.[204][205] Nazi ideology still viewed German men who were gay as a part of the Aryan master race, but the Nazi regime attempted to force them into sexual and social conformity. Homosexuals were viewed as failing in their duty to procreate and reproduce for the Aryan nation. Gay men who would not change or feign a change in their sexual orientation were sent to concentration camps under the "Extermination Through Work" campaign.[206]

Victor Kugler and Johannes Kleiman were arrested and jailed at the penal camp for enemies of the regime at Amersfoort. Kleiman was released after seven weeks, but Kugler was held in various work camps until the war's end.[39] Miep Gies and Bep Voskuijl were questioned and threatened by the Security Police but not detained. They returned to the Achterhuis the following day, and found Anne's papers strewn on the floor. They collected them, as well as several family photograph albums, and Gies resolved to return them to Anne after the war. On 7 August 1944, Gies attempted to facilitate the release of the prisoners by confronting Silberbauer and offering him money to intervene, but he refused.[40]
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 [279][280]
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]
