The last days of Auschwitz, which was opened by the Nazis in Oswiecim, Poland, in 1940, were marked by chaos, cowardice and an attempt to destroy what was once one of Nazi Germany’s most efficient tools in the quest to eradicate European Jews. By late 1944, as the Allied forces of World War II wrested much of occupied Europe out of Nazi hands, it had become clear that the Nazi military—once a mighty force that had invaded and occupied most of Europe after Hitler’s rise to power in 1933—was headed toward a spectacular defeat.
Of the seven people who hid in the secret annex, only Otto Frank survived. Upon returning to Amsterdam on June 3, he discovered that his employees had faithfully kept his business running, awaiting his return. He stayed with Miep Gies and her husband and immediately began searching for his daughters—in mid-July, he learned of their deaths at Bergen-Belsen.
The Republic of Czechoslovakia was home to a substantial minority of Germans, who lived mostly in the Sudetenland. Under pressure from separatist groups within the Sudeten German Party, the Czechoslovak government offered economic concessions to the region.[66] Hitler decided to incorporate not just the Sudetenland but all of Czechoslovakia into the Reich.[67] The Nazis undertook a propaganda campaign to try to generate support for an invasion.[68] Top German military leaders opposed the plan, as Germany was not yet ready for war.[69]
I think this should stay on school book lists because some kids these days see the Holocaust as something that happened a long time ago that is meaningless now, without realizing that genocides and racial motivated violence still happens every day. I think it seems to them like just another thing they have to learn about along with The Hundred Years War and the Crusades.

The Protocols of the Elders of Zion (1912) is an antisemitic forgery created by the secret service of the Russian Empire, the Okhrana. Many antisemites believed it was real and thus it became widely popular after World War I.[92] The Protocols claimed that there was a secret international Jewish conspiracy to take over the world.[93] Hitler had been introduced to The Protocols by Alfred Rosenberg and from 1920 onwards he focused his attacks by claiming that Judaism and Marxism were directly connected, that Jews and Bolsheviks were one and the same and that Marxism was a Jewish ideology-this became known as "Jewish Bolshevism".[94] Hitler believed that The Protocols were authentic.[95]

Polished boots slightly apart, his thumb resting on his pistol belt, Mengele surveyed his prey with those dead gimlet eyes. Death to the left, life to the right. Four hundred thousand souls - babies, small children, young girls, mothers, fathers, and grandparents - are said to have been casually waved to the lefthand side with a flick of the cane clasped in a gloved hand.
In Mein Kampf, Hitler directly attacked both left-wing and right-wing politics in Germany.[75] However, a majority of scholars identify Nazism in practice as being a far-right form of politics.[76] When asked in an interview in 1934 whether the Nazis were "bourgeois right-wing" as alleged by their opponents, Hitler responded that Nazism was not exclusively for any class and indicated that it favoured neither the left nor the right, but preserved "pure" elements from both "camps" by stating: "From the camp of bourgeois tradition, it takes national resolve, and from the materialism of the Marxist dogma, living, creative Socialism".[77]
When the Nazis came to power in Germany, they quickly moved to suppress all real and potential opposition. The general public was intimidated by the arbitrary psychological terror that was used by the special courts (Sondergerichte).[11] Especially during the first years of their existence when these courts "had a strong deterrent effect" against any form of political protest.[12]
