Most of the book is about the privations and hardship of living hidden away in the "annex". There is very little coverage of the violence of the times or much that is going on in the outside world because they had little knowledge of it since they were hidden. I think this is partly why some schoolchildren report the diary is boring. It does get repetitive at times, which reflects the feelings of those living in hiding. They had to wait and wait in fear, not knowing what the next day would bring.
The United States Holocaust Memorial Museum defines the Holocaust as the "systematic, bureaucratic, state-sponsored persecution and murder of six million Jews by the Nazi regime and its collaborators",[29] distinguishing between the Holocaust and the targeting of other groups during "the era of the Holocaust".[30] According to Yad Vashem, Israel's Holocaust memorial, most historians regard the start of the "Holocaust era" as January 1933, when Hitler was named Chancellor of Germany.[31] Other victims of the Holocaust era include those viewed as inferior, including for reasons of race or ethnicity (such as the Roma, ethnic Poles, Russians, and the disabled); and those targeted because of their beliefs or behavior (such as Jehovah's Witnesses, communists, and homosexuals).[30] Hitler came to see the Jews as "uniquely dangerous to Germany", according to Peter Hayes, "and therefore uniquely destined to disappear completely from the Reich and all territories subordinate to it". The persecution and murder of other groups was much less consistent. For example, he writes, the Nazis regarded the Slavs as "sub-human", but their treatment consisted of "enslavement and gradual attrition", while "some Slavs—Slovaks, Croats, Bulgarians, some Ukrainians—[were] allotted a favored place in Hitler's New Order".[20]

Mengele injected chemicals into the eyes of children in an attempt to change their eye color. Unfortunately a strict veil of secrecy over the experiments enabled Mengele to do his work more effectively.The full extent of his gruesome work will never be known because the records he sent to Dr. Von Verschuer at the Kaiser Wilhelm Institute were shipped out in two truckloads and destroyed by the latter.

The political situation in Germany and elsewhere in Europe after World War I (1914–1918) contributed to the rise of virulent antisemitism. Many Germans did not accept that their country had been defeated, which gave birth to the stab-in-the-back myth. This insinuated that it was disloyal politicians, chiefly Jews and communists, who had orchestrated Germany's surrender. Inflaming the anti-Jewish sentiment was the apparent over-representation of Jews in the leadership of communist revolutionary governments in Europe, such as Ernst Toller, head of a short-lived revolutionary government in Bavaria. This perception contributed to the canard of Jewish Bolshevism.[65]
3) The proposed text ends with a quote from Proverbs, “The righteous is an everlasting foundation.” The deeds of the Righteous Gentiles, saving people from persecution and death, are their great memorial. But beyond those individuals who were saved, those deeds present us with an opportunity for a further tikkun. Much has been said and written on the Holocaust’s cataclysmic effect in all aspects of human life – in religion, politics, philosophy, art, in the very term “culture.” Those people who stood up for the persecuted provide a window of hope – the hope that, despite everything, individuals and groups who do good can break through the walls of evil. A “Yizkor for the Righteous Gentiles” expresses the demand to remember this option and the personal obligations it entails.
In the autumn of 1941, SS chief Heinrich Himmler assigned German General Odilo Globocnik (SS and police leader for the Lublin District) with the implementation of a plan to systematically murder the Jews of the Generalgouvernement. The code name Operation Reinhard was eventually given to this plan, named after Heydrich (who was assassinated by Czech partisans in May 1942). As part of Operation Reinhard, Nazi leaders established three killing centers in Poland—Belzec, Sobibor, and Treblinka—with the sole purpose of the mass murder of Jews.
Browning wrestles with these and many other related questions in a consistently persuasive and cogent way. He concludes, very sensibly, that it is inconceivable that the Holocaust, unprecedented in history and entailing a massive, counterproductive diversion of resources in wartime, could have taken place without Hitler’s immediate knowledge and approval, although his orders were often, as Browning notes, “vague and inexplicit.” Moreover, Hitler himself was the chief Nazi ideologue of rabid, demented, racialist anti-Semitism, with anti-Semitism at the very center of his worldview and in and of itself a central motivating factor in his foreign and military policies.
Josef Mengele (/ˈmɛŋɡələ/; German: [ˈmɛŋələ]; 16 March 1911 – 7 February 1979) was a German Schutzstaffel (SS) officer and physician in Auschwitz concentration camp during World War II. He performed deadly human experiments on prisoners and was a member of the team of doctors who selected victims to be killed in the gas chambers. Arrivals that were judged able to work were admitted into the camp, while those deemed unsuitable for labor were sent to the gas chambers to be killed. With Red Army troops sweeping through Poland, Mengele was transferred 280 kilometers (170 mi) from Auschwitz to the Gross-Rosen concentration camp on 17 January 1945, just ten days before the arrival of the Soviet forces at Auschwitz. After the war, he fled to South America where he evaded capture for the rest of his life.
