In her diary, Anne wrote of her very close relationship with her father, lack of daughterly love for her mother (with whom she felt she had nothing in common), and admiration for her sister's intelligence and sweet nature. She did not like the others much initially, particularly Auguste van Pels and Fritz Pfeffer (the latter shared her room). She was at first unimpressed by the quiet Peter; she herself was something of a self-admitted chatterbox (a source of irritation to some of the others). As time went on, however, she and Peter became very close, though she remained uncertain in what direction their relationship would develop.
After the September 1939 German invasion of Poland (the beginning of World War II), anti-Jewish policy escalated to the imprisonment and eventual murder of European Jewry. The Nazis first established ghettos (enclosed areas designed to isolate and control the Jews) in the Generalgouvernement (a territory in central and eastern Poland overseen by a German civilian government) and the Warthegau (an area of western Poland annexed to Germany). Polish and western European Jews were deported to these ghettos where they lived in overcrowded and unsanitary conditions with inadequate food.
Amir told me that Zeidel made several pilgrimages back to Ponar. And yet he was never able to locate the passageway that carried him to freedom. What Zeidel didn’t know was that three years before he died, a Lithuanian archaeologist named Vytautas Urbanavicius had quietly excavated what turned out to be the tunnel’s entrance. But after taking a few photographs and a notebook’s worth of measurements, he sealed up the hole with fresh mortar and stone without pressing any farther or prominently marking the area.
In October 1941, Himmler authorized SS General Odilo Globocnik (SS and police leader for the Lublin District of the Generalgouvernement) to implement a plan to systematically murder all Jews residing in the Generalgouvernement. In 1942, this project received the code name "Operation Reinhard" (Einsatz Reinhard), a reference to Heydrich (who had been authorized to manage the implementation of the "Final Solution" and who was assassinated by Czech agents in May 1942 in Prague).

Peter Hayes (How Was It Possible? A Holocaust Reader, 2015): "The Holocaust, the Nazi attempt to eradicate the Jews of Europe, has come to be regarded as the emblematic event of Twentieth Century ... Hitler's ideology depicted the Jews as uniquely dangerous to Germany and therefore uniquely destined to disappear completely from the Reich and all territories subordinate to it. The threat posted by supposedly corrupting but generally powerless Sinti and Roma was far less, and therefore addressed inconsistently in the Nazi realm. Gay men were defined as a problem only if they were German or having sex with Germans or having sex with Germans and considered 'curable' in most cases. ... Germany's murderous intent toward the handicapped inhabitants of European mental institutions ... was more comprehensive ... but here, too, implementation was uneven and life-saving exceptions permitted, especially in Western Europe. Not only were some Slavs—Slovaks, Croats, Bulgarians, some Ukrainians—allotted a favored place in Hitler's New Order, but the fate of most of the other Slavs the Nazis derided as sub-humans ... consisted of enslavement and gradual attrition, not the prompt massacre meted out to the Jews after 1941."[20]

Even before the Nazis came to power in Germany in 1933, they had made no secret of their anti-Semitism. As early as 1919 Adolf Hitler had written, “Rational anti-Semitism, however, must lead to systematic legal opposition.…Its final objective must unswervingly be the removal of the Jews altogether.” In Mein Kampf (“My Struggle”; 1925–27), Hitler further developed the idea of the Jews as an evil race struggling for world domination. Nazi anti-Semitism was rooted in religious anti-Semitism and enhanced by political anti-Semitism. To this the Nazis added a further dimension: racial anti-Semitism. Nazi racial ideology characterized the Jews as Untermenschen (German: “subhumans”). The Nazis portrayed the Jews as a race and not as a religious group. Religious anti-Semitism could be resolved by conversion, political anti-Semitism by expulsion. Ultimately, the logic of Nazi racial anti-Semitism led to annihilation.
For Levin, the source and first cause of these excisions was Lillian Hellman. Hellman, he believed, had “supervised” the Hacketts, and Hellman was fundamentally political and inflexibly doctrinaire. Her outlook lay at the root of a conspiracy. She was an impenitent Stalinist; she followed, he said, the Soviet line. Like the Soviets, she was anti-Zionist. And, just as the Soviets had obliterated Jewish particularity at Babi Yar, the ravine where thousands of Jews, shot by the Germans, lay unnamed and effaced in their deaths, so Hellman had directed the Hacketts to blur the identity of the characters in the play.
…selected by the camp doctor, Josef Mengele, for medical experiments. Auschwitz doctors tested methods of sterilization on the prisoners, using massive doses of radiation, uterine injections, and other barbaric procedures. Experiments involving the killing of twins, upon whom autopsies were performed, were meant to provide information that would supposedly lead…
In Auschwitz, the murdering of prisoners in gas chambers began even earlier, when 575 sick and disabled prisoners were sent to their deaths at the euthanasia center in Germany at the end of June 1941. At the beginning of September, the SS used Zyklon B gas in the cellars of block 11 to kill about 600 Soviet POWs and another group of patients from the camp hospital. Soviet POWs and Jews brought from Upper Silesia were killed in the gas chamber in crematorium I over the following months. It was probably at the end of March or in April 1942 that the Germans began killing sick prisoners and Jews in a provisional gas chamber in Birkenau (the so-called “little red house”). The tempo of atrocities increased in June and July 1942, with transports of Jews sent to Auschwitz being subjected to systematic “selections” during which SS doctors sentenced people classified as unfit for labor to death.
Although he was raised some 5,000 miles from Lithuania, on Long Island, New York, Freund has deep roots in the area. His great-grandparents fled Vilnius in the early 20th century, during an especially violent series of pogroms undertaken by the Czarist government, when the city still belonged to the Russian Empire. “I’ve always felt a piece of me was there,” Freund told me.
Soon after, a Mossad surveillance team saw a man matching Mengele’s description enter a pharmacy owned by a person who was known to be in touch with him. On July 23, 1962, the Mossad operative Zvi Aharoni (who had identified Eichmann two years earlier) was on a dirt road by the farm where Mengele was believed to be hiding when he encountered a group of men — including one who looked exactly like the fugitive.
The Diary of a Young Girl, also known as The Diary of Anne Frank, is a book of the writings from the Dutch language diary kept by Anne Frank while she was in hiding for two years with her family during the Nazi occupation of the Netherlands. The family was apprehended in 1944, and Anne Frank died of typhus in the Bergen-Belsen concentration camp in 1945. The diary was retrieved by Miep Gies, who ...more
There was "practically no resistance" in the ghettos in Poland by the end of 1942, according to Peter Longerich.[305] Raul Hilberg accounted for this by evoking the history of Jewish persecution: as had been the case before, appealing to their oppressors and complying with orders might avoid inflaming the situation until the onslaught abated.[306] Henri Michel argued that resistance consisted not only of physical opposition but of any activity that gave the Jews humanity in inhumane conditions, while Yehuda Bauer defined resistance as actions that in any way opposed the German directives, laws, or conduct.[307] Hilberg cautioned against overstating the extent of Jewish resistance, arguing that turning isolated incidents into resistance elevates the slaughter of innocent people into some kind of battle, diminishes the heroism of those who took active measures to resist, and deflects questions about the survival strategies and leadership of the Jewish community.[308] Timothy Snyder noted that it was only during the three months after the deportations of July–September 1942 that agreement on the need for armed resistance was reached.[309]

I simply can't build up my hopes on a foundation consisting of confusion, misery and death, I see the world gradually being turned into a wilderness, I hear the ever approaching thunder, which will destroy us too, I can feel the sufferings of millions and yet, if I look up into the heavens, I think that it will all come right, that this cruelty too will end, and that peace and tranquility will return again. In the meantime, I must uphold my ideals, for perhaps the time will come when I shall be able to carry them out.
The Jews killed represented around one third of the world population of Jews,[398] and about two-thirds of European Jewry, based on an estimate of 9.7 million Jews in Europe at the start of the war.[399] Much of the uncertainty stems from the lack of a reliable figure for the number of Jews in Europe in 1939, numerous border changes that make avoiding double-counting of victims difficult, lack of accurate records from the perpetrators, and uncertainty about whether deaths occurring months after liberation, but caused by the persecution, should be counted.[392]

Historians are divided about the motivations of the members of these mobile killing units. American historian Christopher Browning described one such unit, Police Battalion 101, as ordinary men in extraordinary circumstances in which conformity, peer pressure, careerism, obedience to orders, and group solidarity gradually overcame moral inhibitions. American writer Daniel Goldhagen viewed the very same unit as “willing executioners,” sharing Hitler’s vision of genocidal anti-Semitism and finding their tasks unpleasant but necessary. The diversity of the killers has challenged Goldhagen’s view that the motivation was a distinct form of German anti-Semitism. Yet both Browning and Goldhagen concurred that none of these killers faced punishment if he asked to be excused. Individuals had a choice whether to participate or not. Almost all chose to become killers.
When Germany invaded Poland in September 1939, it gained control of about 2 million Jews in the occupied territory. The rest of Poland was occupied by the Soviet Union, which had control of the rest of Poland's pre-war population of 3.3–3.5 million Jews.[141] German plans for Poland included expelling gentile Poles from large areas, confining Jews, and settling Germans on the emptied lands.[142] The Germans initiated a policy of sending Jews from all territories they had recently annexed (Austria, Czechoslovakia, and western Poland) to the central section of Poland, which they called the General Government. There, the Jews were concentrated in ghettos in major cities,[143] chosen for their railway lines to facilitate later deportation.[144] Food supplies were restricted, public hygiene was difficult, and the inhabitants were often subjected to forced labor.[145] In the work camps and ghettos, at least half a million Jews died of starvation, disease, and poor living conditions.[146] Jeremy Black writes that the ghettos were not intended, in 1939, as a step towards the extermination of the Jews. Instead, they were viewed as part of a policy of creating a territorial reservation to contain them.[147][l]
Though it had ancient roots, Nazi ideology was far from a primitive, medieval throwback - it was capable of appealing to intelligent and sophisticated people. Many high-ranking Nazis had doctoral degrees and early supporters included such eminent people as philosopher Martin Heidegger, theologian Martin Niemoeller, and commander-in-chief of German forces in the First World War, General Erich Ludendorff. Hitler appealed with a powerful vision of a strong, united and 'racially' pure Germany, bolstered by pseudo-scientific ideas that were popular at the time.
On January 30, 1933, Adolf Hitler, leader of the National Socialist German Workers (Nazi) Party, was named chancellor of Germany by President Paul von Hindenburg after the Nazi party won a significant percentage of the vote in the elections of 1932. The Nazi Party had taken advantage of the political unrest in Germany to gain an electoral foothold. The Nazis incited clashes with the communists and conducted a vicious propaganda campaign against its political opponents - the weak Weimar government and the Jews whom the Nazis blamed for Germany's ills.
The Summer Olympics in Berlin gave the Nazis a platform to project a crafted image to the world. Despite calls for boycotts, the games were a success. Anti-Jewish notices were removed and German spectators cheered black athlete Jesse Owens to four gold medals. Visitors saw a tolerant Reich. However, three days after the games ended, the head of the Olympic Village, Wolfgang Fürstner, killed himself as he would soon be dismissed due to his Jewish ancestry under the Nuremberg Laws.
The following year, 1941, would be the turning point. In June, Hitler took a tremendous military gamble by invading the Soviet Union. Before the invasion he had summoned his top generals and told them the attack on Russia would be a ruthless "war of annihilation" targeting Communists and Jews and that normal rules of military conflict were to be utterly ignored.
Paradoxically, at the same time that Germany tried to rid itself of its Jews via forced emigration, its territorial expansions kept bringing more Jews under its control. Germany annexed Austria in March 1938 and the Sudetenland (now in the Czech Republic) in September 1938. It established control over the Protectorate of Bohemia and Moravia (now in the Czech Republic) in March 1939. When Germany invaded Poland on September 1, 1939, the “Jewish question” became urgent. When the division of Poland between Germany and the Soviet Union was complete, more than two million more Jews had come under German control. For a time, the Nazis considered shipping the Jews to the island of Madagascar, off the southeast coast of Africa, but discarded the plan as impractical; the Nazis had not prevailed in the Battle of Britain, the seas had become a war zone, and the resources required for such a massive deportation were scarce.
The ghettos, and the slow death they brought, were only part of the overall plan. In the months following the Wannsee Conference, three specialized killing centers, Belzec, Treblinka and Sobibor, were constructed in southeast Poland, featuring large gas chambers with adjacent crematories or burial pits for the disposal of corpses. After they became operational, the ghettos were bypassed and Jews went directly by train to the new death camps.
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.

I expect you will be interested to hear what it feels like to hide; well, all I can say is that I don't know myself yet. I don't think I shall ever feel really at home in this house but that does not mean that I loathe it here, it is more like being on vacation in a very peculiar boardinghouse. Rather a mad way of looking at being in hiding perhaps but that is how it strikes me.

Before the war, Mengele had received doctorates in anthropology and medicine, and began a career as a researcher. He joined the Nazi Party in 1937 and the SS in 1938. He was assigned as a battalion medical officer at the start of World War II, then transferred to the Nazi concentration camps service in early 1943 and assigned to Auschwitz, where he saw the opportunity to conduct genetic research on human subjects. His subsequent experiments focused primarily on twins, with little regard for the health or safety of the victims.[2][3]
