The Nazi concentration camps were established beginning in 1933 for the purpose of imprisoning political opponents. After the “Night of the Long Knives” (see Chapter 8, page 65), authority and management of the concentration camps was turned over to the S.S. The S.S. expanded the concentration camp system, and used these facilities to warehouse other “undesirables,” including hundreds of thousands of Jews. Dachau, Buchenwald and Sachsenhausen were among the first concentration camps built by the Nazis near Munich, Weimar, and Berlin respectively.

Usage Note: Holocaust has a secure place in the language when it refers to the massive destruction of humans by other humans. In our 1987 survey 99 percent of the Usage Panel accepted the use of holocaust in the phrase nuclear holocaust. Sixty percent accepted the sentence As many as two million people may have died in the holocaust that followed the Khmer Rouge takeover in Cambodia. But because of its associations with genocide, people may object to extended applications of holocaust. The percentage of the Panel's acceptance drops sharply when people use the word to refer to death brought about by natural causes. In our 1999 survey 47 percent approved the sentence In East Africa five years of drought have brought about a holocaust in which millions have died. Just 16 percent approved The press gives little coverage to the holocaust of malaria that goes on, year after year, in tropical countries, where there is no mention of widespread mortality. The Panel has little enthusiasm for more figurative usages of holocaust. In 1999, only 7 percent accepted Numerous small investors lost their stakes in the holocaust that followed the precipitous drop in stocks. This suggests that these extended uses of the word may be viewed as overblown or in poor taste.
The SS used Sonderkommandos (Jewish slave laborers) during the gassing process to usher people in the undressing room and to clean up the gas chamber afterwards. One such survivor recalled the scene at Auschwitz: "There were all sorts of reactions from all sorts of people. There were disabled people. They would take out their war service cards showing that they had fought in the First World War with all kinds of distinctions and medals which they had from that time. They shouted, what's this? We fought for Germany. Now they're going to burn us, to kill us. This is impossible. We protest against such a thing. But everyone just laughed at them. Because they didn't take it seriously, these SS men. They laughed at the whole thing."

Browning describes the creation of the extermination camps, which were responsible for the largest number of deaths in the Final Solution, as bringing together three separate developments within the Third Reich: the concentration camps which had been established in Germany since 1933; an expansion of the gassing technology of the Nazi euthanasia programme to provide killing mechanism of greater efficiency and psychological detachment; and the creation of "factories of death" to be fed endless streams of victims by mass uprooting and deportation that utilized the experience and personnel from earlier population resettlement programmes—especially the HSSPF and Adolf Eichmann's RSHA for "Jewish affairs and evacuations".[115]

("I maintain ... that the National Socialist killing of the Jews was unique in that never before had a state with the authority of its leader decided and announced that a specific group of humans, including the elderly, the women, the children and the infants, would be killed as quickly as possible, and then carried out this resolution using every possible means of state power.")[35]
Anne had expressed the desire in the rewritten introduction of her diary for one person that she could call her truest friend, that is, a person to whom she could confide her deepest thoughts and feelings. She observed that she had many "friends" and equally many admirers, but (by her own definition) no true, dear friend with whom she could share her innermost thoughts. She originally thought her girl friend Jacque van Maarsen would be this person, but that was only partially successful. In an early diary passage, she remarks that she is not in love with Helmut "Hello" Silberberg, her suitor at that time, but considered that he might become a true friend. In hiding, she invested much time and effort into her budding romance with Peter van Pels, thinking he might evolve into that one, true friend, but that was eventually a disappointment to her in some ways, also, though she still cared for him very much. Ultimately, it was only to Kitty that she entrusted her innermost thoughts.
Uprisings broke out in some extermination camps. The few remaining Jews kept alive to dispose of bodies and sort possessions realised the number of transportees was reducing and they would be next. Civilian uprisings occurred across Poland as mainly young Jews, whose families had already been murdered, began to resist Nazi oppression. With reports of rebellion and mass murder in the British press, the situation in the camps could no longer be be ignored.
Entering conquered Soviet territories alongside the Wehrmacht (the German armed forces) were 3,000 men of the Einsatzgruppen (“Deployment Groups”), special mobile killing units. Their task was to murder Jews, Soviet commissars, and Roma in the areas conquered by the army. Alone or with the help of local police, native anti-Semitic populations, and accompanying Axis troops, the Einsatzgruppen would enter a town, round up their victims, herd them to the outskirts of the town, and shoot them. They killed Jews in family units. Just outside Kiev, Ukraine, in the ravine of Babi Yar, an Einsatzgruppe killed 33,771 Jews on September 28–29, 1941. In the Rumbula Forest outside the ghetto in Riga, Latvia, 25,000–28,000 Jews were shot on November 30 and December 8–9. Beginning in the summer of 1941, Einsatzgruppen murdered more than 70,000 Jews at Ponary, outside Vilna (now Vilnius) in Lithuania. They slaughtered 9,000 Jews, half of them children, at the Ninth Fort, adjacent to Kovno (now Kaunas), Lithuania, on October 28.
My mother was born in Sofia, Bulgaria, in 1943. The trains were standing by at the stations in Bulgaria’s major cities, waiting to transport Bulgaria’s 50,000 Jews to the death camps. The expulsion order had been given. An unusual coalition of clergy, intellectuals, and politicians, together with large-scale passive resistance by the Bulgarian people, at the last moment prevented Bulgarian Jewry from sharing the tragic fate of Jewish communities in neighboring countries and all over Europe.
With the invasion of the Soviet Union on June 22 1941, the Nazis launched a crusade against 'Judaeo-Bolshevism', the supposed Jewish-Communist conspiracy. Behind the front lines, four police battalions called Einsatzgruppen (operations groups) moved from town to town in the newly occupied Soviet territories, rounding up Jewish men and suspected Soviet collaborators and shooting them. In subsequent sweeps, making heavy use of local volunteers, the Einsatzgruppen targeted Jewish women and children as well. In total, the Einsaztgruppen murdered some two million people, almost all Jews.
Four weeks after the invasion of the Soviet Union, on July 17, 1941, Hitler tasked SS chief Heinrich Himmler with responsibility for all security matters in the occupied Soviet Union. Hitler gave Himmler broad authority to physically eliminate any perceived threats to permanent German rule. Two weeks later, on July 31, Reich Marshall Hermann Göring, acting as Hitler's second-in-command, authorized Reinhard Heydrich, the chief of the Reich Main Office for Security (Reichssicherheitshauptamt; RSHA) and Himmler's direct subordinate, to make preparations for the implementation of a "complete solution of the Jewish question." Henceforth, the SS in general and the RSHA in particular enjoyed Hitler's decision-making authority to manage the implementation of the "Final Solution." [The RSHA consisted of the Security Police (Gestapo and Criminal Police) and the Security Service (Sicherheitsdienst-SD)]
The Final Solution was a plan of Adolf Hitler's to kill all the Jews in Europe. Hitler's Anti- Semitic ideas were so strong that he released hatred by mass murder. Before Hitler decided to become dictator the Final Solution was already in his head. In a couple of books written by Gerald Fleming Hitler says '' Once I  am really in power my first task will be the genocide of the Jews .'' He achieved his goal by killing six million Jews. Hitler began  the final solution in every European Nation he was  control of. The Jews were sent to concentration/death camps.

It is not clear which of the four gas chambers at Birkenau that Litwinska was referring to. The Krema IV and Krema V gas chambers were on the ground floor and had "small windows high up near the roof" where the gas pellets were thrown in by the SS men. But neither of these two gas chambers had a "gas chamber chute" for dumping the victims into the gas chamber from "tipper-type lorries," which Americans would call dump trucks.
Hitler's first step was to take the Jews civil rights away. then he branded and labeled them as if they were cattle. Then he sent them to death and labor camps. If they were they were sent to ghettos. in 1941 most of the Jewish population in Germany would be sent to camps. Nazis racial policies took over everything to try and find a solution for the Jewish question. the Nazis tried to separate them and force migration but when this did not work they found a final solution to the Jewish question. This was the murdering of the Jews in Europe. No-one knows when this decision was made but when the ghettos were built Heydrich said '' this is one step closer to the final aim''.    
In the last months of Hitler’s Reich, as the German armies retreated, the Nazis began marching the prisoners still alive in the concentration camps to the territory they still controlled. The Germans forced the starving and sick Jews to walk hundreds of miles. Most died or were shot along the way. About a quarter of a million Jews died on the death marches.
Who among gentile Poles was most likely to stand up for persecuted Jews? What propelled these rescuers to risk their lives for them? What characteristics, motivations, and circumstances did the rescuers share? Most attempts to answer these questions focus upon standard sociological categories: researchers consider the rescuers’ class, education, political and religious commitments, friendships with Jews, and level of anti-Jewish prejudice. The results of such investigations have not led to clear conclusions. Some studies suggest that economically deprived Christians more readily identified with Jewish suffering. Others conclude that intellectuals were more likely to have been protectors because they had better insight into German aims and were committed to undermining them.
Soviet civilian populations in the occupied areas were heavily persecuted.[438] Villages throughout the Soviet Union were destroyed by German troops.[439] Germans rounded up civilians for forced labor in Germany and caused famine by taking foodstuffs.[440] In Belarus, Germany imposed a regime that deported some 380,000 people for slave labor and killed hundreds of thousands of civilians. Over 600 villages had their entire populations killed, and at least 5,295 Belarusian settlements were destroyed by the Germans. According to Timothy Snyder, of "the nine million people who were in the territory of Soviet Belarus in 1941, some 1.6 million were killed by the Germans in actions away from battlefields, including about 700,000 prisoners of war, 500,000 Jews, and 320,000 people counted as partisans (the vast majority of whom were unarmed civilians)".[441] The United States Holocaust Memorial Museum has estimated that 3.3 million of 5.7 million Soviet POWs died in German custody.[442] The death rates decreased as the POWs were needed to help the German war effort; by 1943, half a million had been deployed as slave labor.[409]
While these massacres were happening, the Nazis elsewhere were laying plans for an overall 'solution to the Jewish question'. Death camp operations began in December 1941 at Semlin in Serbia and Chelmno in Poland, where people were killed by exhaust fumes in specially modified vans, which were then driven to nearby sites where the bodies were plundered and burnt. 250,000 Jews were killed this way at Chelmno and 15,000 at Semlin.

German forces had begun evacuating many of the death camps in the fall of 1944, sending inmates under guard to march further from the advancing enemy’s front line. These so-called “death marches” continued all the way up to the German surrender, resulting in the deaths of some 250,000 to 375,000 people. In his classic book “Survival in Auschwitz,” the Italian Jewish author Primo Levi described his own state of mind, as well as that of his fellow inmates in Auschwitz on the day before Soviet troops arrived at the camp in January 1945: “We lay in a world of death and phantoms. The last trace of civilization had vanished around and inside us. The work of bestial degradation, begun by the victorious Germans, had been carried to conclusion by the Germans in defeat.”

Most of the Jewish ghettos of General Government were liquidated in 1942–1943, and their populations shipped to the camps for extermination.[349][350][t] About 42,000 Jews were shot during the Operation Harvest Festival on 3–4 November 1943.[351] At the same time, rail shipments arrived regularly from western and southern Europe at the extermination camps.[352] Few Jews were shipped from the occupied Soviet territories to the camps: the killing of Jews in this zone was mostly left in the hands of the SS, aided by locally recruited auxiliaries.[353][u]

I was miserable being me. . . . I was on the brink of that awful abyss of teenagedom and I, too, needed someone to talk to. . . . (Ironically, Anne, too, expressed a longing for more attention from her father.) . . . Dad’s whole life was a series of meetings. At home, he was too tired or too frustrated to unload on. I had something else in common with Anne. We both had to share with sisters who were prettier and smarter than we felt we were. . . . Despite the monumental differences in our situations, to this day I feel that Anne helped me get through the teens with a sense of inner focus. She spoke for me. She was strong for me. She had so much hope when I was ready to call it quits.

Following the invasion of Poland, German occupation policy especially targeted the Jews but also brutalized non-Jewish Poles. In pursuit of lebensraum, Germany sought systematically to destroy Polish society and nationhood. The Nazis killed Polish priests and politicians, decimated the Polish leadership, and kidnapped the children of the Polish elite, who were raised as “voluntary Aryans” by their new German “parents.” Many Poles were also forced to perform hard labour on survival diets, were deprived of property and uprooted, and were interned in concentration camps.
As the unsuspecting people were herded off the train and ordered into separate lines, SS officers shouted in German, "Zwillinge!" (Twins!). Parents were forced to make a quick decision. Unsure of their situation, already being separated from family members when forced to form lines, seeing barbed wire, smelling an unfamiliar stench -- was it good or bad to be a twin?
The Nazis attempted to quell increasing reports of the Final Solution by inviting the International Red Cross to visit Theresienstadt, a ghetto in Czechoslovakia containing prominent Jews. A Red Cross delegation toured Theresienstadt in July 1944 observing stores, banks, cafes, and classrooms which had been hastily spruced-up for their benefit. They also witnessed a delightful musical program put on by Jewish children. After the Red Cross departed, most of the ghetto inhabitants, including all of the children, were sent to be gassed and the model village was left to deteriorate.
Mengele fled Germany to Argentina in 1948, using false documents given to him by the Red Cross. (According to the Mossad’s file, the organization was aware that it was helping a Nazi criminal escape justice.) In Buenos Aires, he lived at first under an assumed name, but later reverted to his own name. He even had a nameplate on his door: Dr. Josef Mengele.
In 1969, Mengele and the Stammers jointly purchased a farmhouse in Caieiras, with Mengele as half owner.[93] When Wolfgang Gerhard returned to Germany in 1971 to seek medical treatment for his ailing wife and son, he gave his identity card to Mengele.[94] The Stammers' friendship with Mengele deteriorated in late 1974 and when they bought a house in São Paulo, Mengele was not invited to join them.[b] The Stammers later bought a bungalow in the Eldorado neighborhood of São Paulo, which they rented out to Mengele.[97] Rolf, who had not seen his father since the ski holiday in 1956, visited him at the bungalow in 1977; he found an unrepentant Nazi who claimed he had never personally harmed anyone, only having carried out his duty.[98]
