In 1933, Jews in Germany numbered around 525,000, or only 1 percent of the total German population. During the next six years, Nazis undertook an “Aryanization” of Germany, dismissing non-Aryans from civil service, liquidating Jewish-owned businesses and stripping Jewish lawyers and doctors of their clients. Under the Nuremberg Laws of 1935, anyone with three or four Jewish grandparents was considered a Jew, while those with two Jewish grandparents were designated Mischlinge (half-breeds).
About two-thirds of the overall number of victims of the Final Solution were killed before February 1943,[87] which included the main phase of the extermination programme in the West launched by Eichmann on 11 June 1942 from Berlin.[88] The Holocaust trains run by the Deutsche Reichsbahn and several other national railway systems delivered condemned Jewish captives from as far as Belgium, Bulgaria, France, Greece, Hungary, Italy, Moravia, Netherlands, Romania, Slovakia, and even Scandinavia.[89][90] The cremation of exhumed corpses to destroy any evidence left behind began in early spring and continued throughout summer.[91] The nearly completed clandestine programme of murdering all deportees was explicitly addressed by Heinrich Himmler in his Posen speeches made to the leadership of the Nazi Party on 4 October and during the Posen Conference of 6 October 1943 in occupied Poland. Himmler explained why the Nazi leadership found it necessary to kill Jewish women and children along with the Jewish men. The assembled functionaries were told that the Nazi state policy was "the extermination of the Jewish people" as such.[92]

Before the the Final Solution the plan the Nazis had was to force the Jews to immigration. In 1940 the nazis planed to ship the Jews to an Island in the Indian ocean called Madagascar. it was not until later they referred to the Final Solution as genocide rather than territorial Final Solution. As the nazis were under cover of the war they developed technology to successfully murder millions of Jews. details were worked out at the Wansee Conference. All Jews in Germanys occupied countries were sent to ghettos as holding areas. Many were sent to camps were they worked under brutal conditions. Many were sent to gas chambers. As the Allies advanced death marches cut down the number of potential survivors. Some of Hitler's objectives were to wage to wars at once one aimed at anyone who objected him the other at the Jews. Hitler's success was credited to planed steps and reaction to those of other world powers. 
Whereas Christopher Browning places the Nazi plan to exterminate the Jews in the context of the Wehrmacht victories on the Eastern front, Cesarani argues that the German subsequent realisation that there would be no swift victory over the Soviet Union "scuppered the last territorial 'solution' still on the table: expulsion to Siberia".[119] Germany's declaration of war on the United States on December 11, 1941, "meant that holding European Jews hostage to deter the US from entering the conflict was now pointless. As Joseph Goebbels put it when he summarised a secret speech Hitler made on 12 December 1941: 'The world war is here, the destruction of the Jews must be the inevitable consequence'."[119][120] Cesarani concludes, the Holocaust "was rooted in anti-Semitism, but it was shaped by war".[119] The fact that the Nazis were, ultimately, so successful in killing between five and six million Jews was not due to the efficiency of the Third Reich or the clarity of their policies. "Rather, the catastrophic rate of killing was due to German persistence … and the duration of the murderous campaigns. This last factor was largely a consequence of allied military failure."[121]
This isn't a review- I'm not going to go into my reasons for giving this book 2 stars. That would not do anybody any good. I will simply say that I feel extremely guilty rating the book this low, but I hope people understand that it doesn't reflect my view of the Holocaust as a whole, or my views of Anne Frank as a person. I have the utmost respect for both.
Broadly speaking, the extermination of Jews was carried out in two major operations. With the onset of Operation Barbarossa, launched from occupied Poland in June 1941, mobile killing units of the SS and Orpo were dispatched to Soviet controlled territories of eastern Poland and further into the Soviet republics for the express purpose of killing all Jews, both Polish and Soviet. During the massive chase after the fleeing Red Army, Himmler himself visited Białystok in the beginning of July 1941, and requested that, "as a matter of principle, any Jew" behind the German-Soviet frontier "was to be regarded as a partisan". His new orders gave the SS and police leaders full authority for the mass murder behind the front-lines. By August 1941, all Jewish men, women, and children were shot.[21] In the second phase of annihilation, the Jewish inhabitants of central, western, and south-eastern Europe were transported by Holocaust trains to camps with newly-built gassing facilities. Raul Hilberg wrote: "In essence, the killers of the occupied USSR moved to the victims, whereas outside this arena, the victims were brought to the killers. The two operations constitute an evolution not only chronologically, but also in complexity."[9] Massacres of about one million Jews occurred before plans for the Final Solution were fully implemented in 1942, but it was only with the decision to annihilate the entire Jewish population that extermination camps such as Auschwitz II Birkenau and Treblinka were fitted with permanent gas chambers to kill large numbers of Jews in a relatively short period of time.[22][23]
Upon arrival at a camp, the inmates were usually stripped of all their valuables and clothes. They were then shorn of body hair, disinfected, given a shower, and issued a striped prison uniform without regard to size. Each step of the process was designed to dehumanize the prisoners, both physically and emotionally. Each prisoner was given a number. At Auschwitz, for example, the number was tattooed on the arm, but some camps did not tattoo their inmates.
Eichmann received various levels of cooperation from each of the various occupied governments. But in countries such as Holland, Belgium, Albania, Denmark, Finland and Bulgaria, some Jews were saved from their deaths by the action of the sympathetic populace and government officials. Denmark’s government and populace were exemplary in their heroism in saving Jews. In other countries such as Poland, Greece, France, and Yugoslavia, the deportation of Jews to the death camps was facilitated by the cooperation of the government.

The Nazi killing site at Ponar is today known to scholars as one of the first examples of the “Holocaust by bullets”—the mass shootings that claimed the lives of upwards of two million Jews across Eastern Europe. Unlike the infamous gas chambers at places like Auschwitz, these murders were carried out at close range, with rifles and machine guns. Significantly, the killings at Ponar marked the transition to the Final Solution, the Nazi policy under which Jews would no longer be imprisoned in labor camps or expelled from Europe but exterminated.

In his bunker, in the Chancellory building in Berlin, knowing that the war was lost and that the “1,000 Year Reich” had lasted only a few years, Hitler committed suicide hours after marrying Eva Braun. Germany formally surrendered to the Allies on May 7, 1945. By the end of the war, more than 55 million had died and 35 million wounded. Only 17 million of the dead were soldiers.
Twins in the experiments describe three days of what must have been psychological examination and three days of laboratory experiments. "Three times a week we were marched to Auschwitz to a big brick building, sort of like a big gymnasium. They would keep us there for about six or eight hours at a time - most of the days. ..... We would have to sit naked in the large room where we first entered, and people in white jackets would observe us and write down notes. They also would study every part of our bodies. They would photograph, measure our heads and arms and bodies, and compare the measurements of one twin to another. The process seemed to go on and on." (Echoes from Auschwitz, Kor).

The Germans required each ghetto to be run by a Judenrat, or Jewish council.[205] Councils were responsible for a ghetto's day-to-day operations, including distributing food, water, heat, medical care, and shelter. The Germans also required councils to confiscate property, organize forced labor, and, finally, facilitate deportations to extermination camps.[206] The councils' basic strategy was one of trying to minimize losses, by cooperating with German authorities, bribing officials, and petitioning for better conditions or clemency.[207]
Shortly after Hitler came to power, the Reichstag building, seat of the German parliament, burnt down. Communists were blamed for setting the fire and Hindenburg declared a state of emergency, passing the Reichstag Fire Decree that suspended basic rights like trial by jury. The German Communist Party was suspended and over 4,000 members were detained without trial. The next month, Hitler’s cabinet passed the Enabling Act which allowed him to enact laws without the consent of the parliament for four years, effectively transforming the German government into a de facto Nazi dictatorship.
This meeting, which would be followed by the January 1942 Wannsee Conference (where the decision on exterminating all European Jews was further reinforced), was hardly the start of violence against Jews. Attacks had been happening in Nazi Germany’s occupied territories for years. What differentiated this period from earlier attacks was “an escalation of murder,” says Elizabeth White, historian at the United States Holocaust Memorial Museum.
German-occupied Denmark rescued most of its own Jews by spiriting them to Sweden by sea in October 1943. This was possible partly because the German presence in Denmark was relatively small. Moreover, while anti-Semitism in the general population of many other countries led to collaboration with the Germans, Jews were an integrated part of Danish culture. Under these unique circumstances, Danish humanitarianism flourished.

Anne's already budding literary ambitions were galvanized on 29 March 1944 when she heard a London radio broadcast made by the exiled Dutch Minister for Education, Art, and Science, Gerrit Bolkestein,[17] calling for the preservation of "ordinary documents—a diary, letters ... simple everyday material" to create an archive for posterity as testimony to the suffering of civilians during the Nazi occupation. On May 20, 1944, she notes that she started re-drafting her diary with future readers in mind.[19] She expanded entries and standardized them by addressing all of them to Kitty, clarified situations, prepared a list of pseudonyms, and cut scenes she thought would be of little interest or too intimate for general consumption. By the time she started the second existing volume, she was writing only to Kitty.
According to the drawings done by Walter Dejaco, one of the architects of the Krema II building, the original blueprint showed a corpse slide for rolling bodies down into the vestibule between the two morgues, which were later converted into an undressing room and a gas chamber. The corpse slide was never built. Dejaco was acquitted by a court in Austria in 1972; at his trial, the drawings of the corpse slide were entered as evidence. (The morgue at the Sachsenhausen camp has a corpse slide which can still be seen today.)
The biblical term shoah (Hebrew: שׁוֹאָה), meaning "destruction", became the standard Hebrew term for the murder of the European Jews, first used in a pamphlet in 1940, Sho'at Yehudei Polin ("Sho'ah of Polish Jews"), published by the United Aid Committee for the Jews in Poland.[11] On 3 October 1941 the cover of the magazine The American Hebrew used the phrase "before the Holocaust", apparently to refer to the situation in France,[12] and in May 1943 The New York Times, discussing the Bermuda Conference, referred to the "hundreds of thousands of European Jews still surviving the Nazi Holocaust".[13] In 1968 the Library of Congress created a new category, "Holocaust, Jewish (1939–1945)".[14] The term was popularized in the United States by the NBC mini-series Holocaust (1978), about a fictional family of German Jews,[15] and in November 1978 the President's Commission on the Holocaust was established.[16] As non-Jewish groups began to include themselves as Holocaust victims too, many Jews chose to use the terms Shoah or Churban instead.[12][g] The Nazis used the phrase "Final Solution to the Jewish Question" (German: die Endlösung der Judenfrage).[18]

Gentiles whose status placed them on the periphery of a community generally had fewer social constraints and a higher level of independence. This sense of independence, in turn, seems to have made many rescuers more likely to act in accordance with their personal values and moral precepts, even when these standards were in opposition to societal norms. Such rescuers were propelled by values connected to self-approval. In interviews, they insisted again and again that they had to be at peace with themselves, with their ideas of what was right or wrong.

In addition to active help, many clergymen also protested the mistreatment and deportations of Jews as violations of divine and human laws. The Catholic pastor of St. Hedwig’s Cathedral in Berlin, Bernard Lichtenburg, prayed publicly for the Jews until his arrest and death on the way to Dachau. The rescue work of priests of all Christian denominations is well-documented in postwar literature.
The Nazis used the phrase Lebensunwertes Leben (life unworthy of life) in reference to the disabled and mentally ill.[92] On 14 July 1933, the Law for the Prevention of Hereditarily Diseased Offspring (Gesetz zur Verhütung erbkranken Nachwuchses), the Sterilization Law, was passed, allowing for compulsory sterilization.[93][94] The New York Times reported on 21 December that year: "400,000 Germans to be sterilized".[95] There were 84,525 applications from doctors in the first year. The courts reached a decision in 64,499 of those cases; 56,244 were in favor of sterilization.[96] Estimates for the number of involuntary sterilizations during the whole of the Third Reich range from 300,000 to 400,000.[97]
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.
After several months on the run, including a trip back to the Soviet-occupied area to recover his Auschwitz records, Mengele found work near Rosenheim as a farmhand.[62] He eventually escaped from Germany on 17 April 1949,[63][64] convinced that his capture would mean a trial and death sentence. Assisted by a network of former SS members, he used the ratline to travel to Genoa, where he obtained a passport from the International Committee of the Red Cross under the alias "Helmut Gregor", and sailed to Argentina in July 1949.[65] His wife refused to accompany him, and they divorced in 1954.[66]
