When Germany invaded Poland in September 1939, triggering World War II, Adolf Hitler ordered that the Polish leadership and intelligentsia be destroyed.[16] Approximately 65,000 civilians, viewed as inferior to the Aryan master race, had been killed by the end of 1939. In addition to leaders of Polish society, the Nazis killed Jews, prostitutes, the Roma, and the mentally ill.[17][18] SS-Obergruppenführer Reinhard Heydrich, then head of the Gestapo, ordered on 21 September 1939 that Polish Jews be rounded up and concentrated into cities with good rail links. Initially the intention was to deport them to points further east, or possibly to Madagascar.[19] Two years later, in June 1941, in an attempt to obtain new territory, Hitler invaded the Soviet Union.[8]
As the Soviet Army advanced from the east, the Nazis transported prisoners away from the front and deep into Germany. Some prisoners were taken from the camps by train, but most were force-marched hundreds of miles, often in freezing weather and without proper clothing or shoes. Over the course of these death marches, which sometimes lasted weeks, tens of thousands of people died from cold or hunger, or were shot because they could not keep up.
I bought this book to prepare for a trip to the Anne Frank Museum. It was a sad but fascinating read - and when I got to the Franks' hiding place in Amsterdam, I knew exactly what I was looking at, who slept where - and who all the individuals were that helped Anne, her family, and their companions survive for as long as they did. I think I got more out of the visit than I would have without reading this book.

[Hitler] compiled a most extensive set of revolutionary goals (calling for radical social and political change); he mobilized a revolutionary following so extensive and powerful that many of his aims were achieved; he established and ran a dictatorial revolutionary state; and he disseminated his ideas abroad through a revolutionary foreign policy and war. In short, he defined and controlled the National Socialist revolution in all its phases.[283]

With Hitler's approval, Himmler intended that the new society of the Nazi regime should destigmatise illegitimate births, particularly of children fathered by members of the SS, who were vetted for racial purity.[385] His hope was that each SS family would have between four and six children.[385] The Lebensborn (Fountain of Life) association, founded by Himmler in 1935, created a series of maternity homes to accommodate single mothers during their pregnancies.[386] Both parents were examined for racial suitability before acceptance.[386] The resulting children were often adopted into SS families.[386] The homes were also made available to the wives of SS and NSDAP members, who quickly filled over half the available spots.[387]
The concept of the Aryan race, which the Nazis promoted, stems from racial theories asserting that Europeans are the descendants of Indo-Iranian settlers, people of ancient India and ancient Persia.[80] Proponents of this theory based their assertion on the fact that words in European languages and words in Indo-Iranian languages have similar pronunciations and meanings.[80] Johann Gottfried Herder argued that the Germanic peoples held close racial connections to the ancient Indians and the ancient Persians, who he claimed were advanced peoples that possessed a great capacity for wisdom, nobility, restraint and science.[80] Contemporaries of Herder used the concept of the Aryan race to draw a distinction between what they deemed to be "high and noble" Aryan culture versus that of "parasitic" Semitic culture.[80]
Subject to harsh conditions—including inadequate shelter and sanitation—given minimal food, and worked to exhaustion, those who could no longer work faced transport back to Birkenau for gassing. German corporations invested heavily in the slave-labour industries adjacent to Auschwitz. In 1942 IG Farben alone invested more than 700 million Reichsmarks in its facilities at Auschwitz III.
The Nazis took things further, one step at the time. Jews had to start wearing a Star of David on their clothes and there were rumours that all Jews would have to leave the Netherlands. When Margot received a call-up to report for a so-called ‘labour camp’ in Nazi Germany on 5 July 1942, her parents were suspicious. They did not believe the call-up was about work and decided to go into hiding the next day in order to escape persecution.  

Same edition as the one I have read from my local library. This appears to be as fine an edition as you can get, and I have done a fair amount of research on that. This, the "definitive edition" has a lot of material that did not appear in the original one that was edited by Anne's father after the war. It also is on superior paper, with very readable type, and the photos are clearly rendered, compared to the other editions I have had in hand.
Most of the judicial system and legal codes of the Weimar Republic remained in place to deal with non-political crimes.[206] The courts issued and carried out far more death sentences than before the Nazis took power.[206] People who were convicted of three or more offences—even petty ones—could be deemed habitual offenders and jailed indefinitely.[207] People such as prostitutes and pickpockets were judged to be inherently criminal and a threat to the community. Thousands were arrested and confined indefinitely without trial.[208]
The National Socialist Programme was a formulation of the policies of the party. It contained 25 points and is therefore also known as the "25-point plan" or "25-point programme". It was the official party programme, with minor changes, from its proclamation as such by Hitler in 1920, when the party was still the German Workers' Party, until its dissolution.
Following the camp's liberation, the Soviet government issued a statement, on 8 May 1945, that four million people had been killed on the site, a figure based on the capacity of the crematoria and later regarded as too high.[185] Höss told prosecutors at Nuremberg that at least 2,500,000 people had been murdered in Auschwitz by gassing and burning, and that another 500,000 had died of starvation and disease.[186] He testified that the figure of over two million had come from Eichmann.[187][d] In his memoirs, written in custody, he wrote that he regarded this figure as "far too high. Even Auschwitz had limits to its destructive possibilities."[189] Raul Hilberg's 1961 work, The Destruction of the European Jews, estimated that up to 1,000,000 Jews had died in Auschwitz.[190]
In the spring of 1941, the SS—along with doctors and officials of the T-4 Euthanasia Program—introduced the Action 14f13 programme meant for extermination of selected concentration camp prisoners.[31] The Inspectorate of the Concentration Camps categorized all files dealing with the death of prisoners as 14f, and those of prisoners sent to the T-4 gas chambers as 14f13. Under the language regulations of the SS, selected prisoners were designated for "special treatment (German: Sonderbehandlung) 14f13". Prisoners were officially selected based on their medical condition; namely, those permanently unfit for labor due to illness. Unofficially, racial and eugenic criteria were used: Jews, the handicapped, and those with criminal or antisocial records were selected.[32]:p.144 For Jewish prisoners there was not even the pretense of a medical examination: the arrest record was listed as a physician's "diagnosis".[32]:pp. 147–148 In early 1943, as the need for labor increased and the gas chambers at Auschwitz became operational, Heinrich Himmler ordered the end of Action 14f13.[32]:p.150
