The Soviet Army reached Auschwitz on January 27, 1945. By that time, an estimated 1,500,000 Jews, along with 500,000 Polish prisoners, Soviet POWs and Gypsies, had perished there. As the Western Allies pushed into Germany in the spring of 1945, they liberated Buchenwald, Bergen-Belsen, and Dachau. Now the full horror of the twelve-year Nazi regime became apparent as British and American soldiers, including Supreme Commander Dwight D. Eisenhower, viewed piles of emaciated corpses and listened to vivid accounts given by survivors.
The memory of this slightly built man, scarcely a hair out of place, his dark green tunic neatly pressed, his face well scrubbed, his Death's Head SS cap tilted rakishly to one side, remains vivid for those who survived his scrutiny when they arrived at the Auschwitz railhead. Polished boots slightly apart, his thumb resting on his pistol belt, he 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.

These evacuations were regarded as provisional or "temporary solutions" ("Ausweichmöglichkeiten").[266][p] The final solution would encompass the 11 million Jews living not only in territories controlled by Germany, but elsewhere in Europe and adjacent territories, such as Britain, Ireland, Switzerland, Turkey, Sweden, Portugal, Spain, and Hungary, "dependent on military developments".[266] There was little doubt what the final solution was, writes Peter Longerich: "the Jews were to be annihilated by a combination of forced labour and mass murder".[268]

Mengele fled Germany to Argentina in 1948, using false documents given to him by the Red Cross. (According to the Mossad’s file, the organization was aware that it was helping a Nazi criminal escape justice.) In Buenos Aires, he lived at first under an assumed name, but later reverted to his own name. He even had a nameplate on his door: Dr. Josef Mengele.
“In any of these circumstances, what you want—the biggest thing you want, the most important—is to be able to make these places visible,” Freund told me later, back in Vilnius. “Your goal is to mark them in a way that people can come to them with tears in their eyes, come to them as memorials, come to them to say the mourner’s kaddish. Because the worst thing would be to look away. To forget.”
Throughout the Middle Ages in Europe, Jews were subjected to antisemitism based on Christian theology, which blamed them for killing Jesus. Even after the Reformation, Catholicism and Lutheranism continued to persecute Jews, accusing them of blood libels and subjecting them to pogroms and expulsions.[60][61] The second half of the 19th century saw the emergence in the German empire and Austria-Hungary of the völkisch movement, which was developed by such thinkers as Houston Stewart Chamberlain and Paul de Lagarde. The movement embraced a pseudo-scientific racism that viewed Jews as a race whose members were locked in mortal combat with the Aryan race for world domination.[62] These ideas became commonplace throughout Germany,[63] with the professional classes adopting an ideology that did not see humans as racial equals with equal hereditary value.[64] Although the völkisch parties had support in elections at first, by 1914 they were no longer influential. This did not mean that antisemitism had disappeared; instead it was incorporated into the platforms of several mainstream political parties.[63]

They set off at 11 p.m., in groups of ten. The first group emerged from the tunnel without incident. Zeidel recalled slithering on his stomach toward the edge of the camp. He scarcely dared to exhale; his heart slammed against his chest wall. Later, Farber would speculate that it was the snap of a twig that alerted their captors to the escape. Dogim attributed it to a blur of movement spotted by the guards.
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]
The ideology of Nazism brought together elements of antisemitism, racial hygiene, and eugenics, and combined them with pan-Germanism and territorial expansionism with the goal of obtaining more Lebensraum (living space) for the Germanic people.[16] Nazi Germany attempted to obtain this new territory by attacking Poland and the Soviet Union, intending to deport or kill the Jews and Slavs living there, who were considered by the Nazis to be inferior to the Aryan master race.[17]
