Their decency exposed them to the dangers of discovery and denunciation. If caught, they faced torture, deportation to concentration camps, or execution. Their behavior was atypical even in their own communities, where the attitude of the majority was characterized by inertia, indifference, and open complicity in the persecution and mass murder of Europe’s Jews.
And once you finish this book, you'll have seen a vision of history through the eyes of an incredibly eloquent teenager—and, what's more, an incredibly real teenager. We're not just talking about the fact that these words were actually written down by the actual Anne Frank in the actual Secret Annex during the actual monstrosity that was the Holocaust (although that blows our mind every time). We're talking about the fact that Anne is completely relatable.
When the Nazis occupied western Poland in 1939, two-thirds of Polish Jews - Europe's largest Jewish community - fell into their hands. The Polish Jews were rounded up and placed in ghettos, where it is estimated that 500,000 people died of starvation and disease. Nazi policy at this point was aimed at forced emigration and isolation of the Jews rather than mass murder, but large numbers were to die through attrition.
After only four days of working in Hamburg, Ruth Elias was escorted by an SS man, in a private compartment on a passenger train, to the infirmary at Ravensbrück, the women's concentration camp near Berlin. From there, Ruth and Berta Reich, another prisoner who was nine months pregnant, were soon sent back to Auschwitz on another passenger train. Ruth gave birth to a baby girl at Auschwitz, but Dr. Mengele cruelly ordered her to bind her breasts and not to nurse her child because he wanted to see how long it would take for a baby to die without its mother's milk. Mercifully, a woman dentist named Maca Steinberg, who was a prisoner at Auschwitz, obtained some morphine and gave it to Ruth so that she could inject her baby and end its life, after Ruth told her that Dr. Mengele was due to arrive the next morning to take Ruth and her child to the gas chamber.
In his 1965 essay "Command and Compliance", which originated in his work as an expert witness for the prosecution at the Frankfurt Auschwitz Trials, the German historian Hans Buchheim wrote there was no coercion to murder Jews and others, and all who committed such actions did so out of free will. Buchheim wrote that chances to avoid executing criminal orders "were both more numerous and more real than those concerned are generally prepared to admit",[468] and that he found no evidence that SS men who refused to carry out criminal orders were sent to concentration camps or executed.[469] Moreover, SS rules prohibited acts of gratuitous sadism, as Himmler wished for his men to remain "decent"; acts of sadism were carried out on the initiative of those who were either especially cruel or wished to prove themselves ardent National Socialists.[468] Finally, he argued that those of a non-criminal bent who committed crimes did so because they wished to conform to the values of the group they had joined and were afraid of being branded "weak" by their colleagues if they refused.[470]
The capture and trial of Eichmann — and his execution — were enough to teach the world about the Holocaust and to convey the message that Jewish blood cannot be spilled with impunity. From that point on, it would have been better if the Mossad had let the past go. Nazis no longer posed a threat. And there is no lack of present-day enemies who did and apparently always will.
Transportation between camps was often carried out in freight cars with prisoners packed tightly. Long delays would take place; prisoners might be confined in the cars on sidings for days.[190] In mid-1942 work camps began requiring newly arrived prisoners to be placed in quarantine for four weeks.[191] Prisoners wore colored triangles on their uniforms, the color of the triangle denoting the reason for their incarceration. Red signified a political prisoner, Jehovah's Witnesses had purple triangles, "asocials" and criminals wore black and green. Badges were pink for gay men and yellow for Jews.[192] Jews had a second yellow triangle worn with their original triangle, the two forming a six-pointed star.[193][194] In Auschwitz, prisoners were tattooed with an identification number on arrival.[195]
The Nazis regarded the Slavs as subhuman, or Untermenschen.[426] In a secret memorandum dated 25 May 1940, Himmler stated that it was in German interests to foster divisions between the ethnic groups in the East. He wanted to restrict non-Germans in the conquered territories to schools that would only teach them how to write their own name, count up to 500, and obey Germans.[427][y] In November 1939 German planners called for "the complete destruction" of all Poles[430] and resettlement of the land by German colonists.[431] The Polish political leadership was the target of a campaign of murder (Intelligenzaktion and AB-Aktion).[432] Between 1.8 and 1.9 million non-Jewish Polish citizens perished at German hands during the course of the war; about four-fifths were ethnic Poles and the rest Ukrainians and Belarusians.[410] At least 200,000 died in concentration camps, around 146,000 in Auschwitz. Others died in massacres or in uprisings such as the Warsaw Uprising, where 120,000–200,000 were killed.[433] During the occupation, the Germans adopted a policy of restricting food and medical services, as well as degrading sanitation and public hygiene.[434] The death rate rose from 13 per 1000 before the war to 18 per 1000 during the war.[435] Around 6 million of World War II victims were Polish citizens; half the death toll were Jews.[436] Over the course of the war Poland lost 20 percent of its pre-war population.[436] Over 90 percent of the death toll came through non-military losses, through various deliberate actions by Germany and the Soviet Union.[433] Polish children were also kidnapped by Germans to be "Germanized", with perhaps as many as 200,000 children stolen from their families.[437]

In the first phase of the experiments, pairs of twins and persons with inherited anomalies were put at the disposal of Dr. Mengele and subjected to all imaginable specialist medical examinations. They were also photographed, plaster casts were made of their jaws and teeth, and they were toe- and fingerprinted. As soon as these examinations were finished, they were killed with lethal injections of phenol to the heart so that the next phase of the experimentation could begin: autopsies and the comparative analysis of their internal organs.
France had approximately 300,000 Jews, divided between the German-occupied north and the unoccupied collaborationist southern areas under the Vichy regime. The occupied regions were under the control of a military governor, and there, anti-Jewish measures were not enacted as quickly as they were in the Vichy-controlled areas.[163] In July 1940, the Jews in the parts of Alsace-Lorraine that had been annexed to Germany were expelled into Vichy France.[164] Vichy France's government implemented anti-Jewish measures in French Algeria and the two French Protectorates of Tunisia and Morocco.[165] Tunisia had 85,000 Jews when the Germans and Italians arrived in November 1942. An estimated 5,000 Jews were subjected to forced labor.[166]
The Final Solution (German: Endlösung) or the Final Solution to the Jewish Question (German: die Endlösung der Judenfrage, pronounced [diː ˈɛntˌløːzʊŋ deːɐ̯ ˈjuːdn̩ˌfʁaːɡə]) was a Nazi plan for the genocide of Jews during World War II. The "Final Solution of the Jewish Question" was the official code name for the murder of all Jews within reach, which was not restricted to the European continent.[1] This policy of deliberate and systematic genocide starting across German-occupied Europe was formulated in procedural and geo-political terms by Nazi leadership in January 1942 at the Wannsee Conference held near Berlin,[2] and culminated in the Holocaust, which saw the killing of 90% of Polish Jews,[3] and two thirds of the Jewish population of Europe.[4]
Although Yad Vashem (Israel’s Memorial to the Six Million) has honored over 1,200 Righteous Among the Nations since 1953, it is impossible to generalize about the motives, deeds, and actual numbers of these rescuers. Some rescuers acted within the planned context of guerrilla units and resistance movements, others used the buildings and funds of the Roman Catholic church to aid Jews.
Three defendants were acquitted. However, many of the Nazis who perpetrated the Holocaust were never tried or punished, including Hitler who had committed suicide. Since then, the international community has continued and improved accountability through forums such as the International Criminal Court, and the International Criminal Tribunal for Rwanda.
Hitler's first step was to take the Jews civil rights away. then he branded and labeled them as if they were cattle. Then he sent them to death and labor camps. If they were they were sent to ghettos. in 1941 most of the Jewish population in Germany would be sent to camps. Nazis racial policies took over everything to try and find a solution for the Jewish question. the Nazis tried to separate them and force migration but when this did not work they found a final solution to the Jewish question. This was the murdering of the Jews in Europe. No-one knows when this decision was made but when the ghettos were built Heydrich said '' this is one step closer to the final aim''.    
Freund and his colleagues, including Harry Jol, a professor of geology and anthropology from the University of Wisconsin, Eau Claire, and Philip Reeder, a geoscientist and mapping expert from Duquesne University, in Pittsburgh, were brought in to explore further. They spent five days scanning the ground beneath the school and the surrounding landscape with ground-penetrating radar, and emerged with a detailed digital map that displayed not just the synagogue’s main altar and seating area but also a separate building that held a bathhouse containing two mikvaot, or ceremonial baths, a well for water and several latrines. Afterward, Freund met with the staff at the Vilna Gaon Jewish State Museum, named after the famed 18th-century Talmudic scholar from Vilnius, and a partner on the Great Synagogue project. Then, Freund said, “We asked them: ‘What else would you like us to do? We’ll do it for free.’”
Concentration camp crematorium being shown to a US soldier  © Organised killing began with the outbreak of war in September 1939, but the first victims were not Jews. The Nazis set about killing people with physical and mental disabilities, whom they regarded as a burden on the state and a threat to the nation's 'racial hygiene'. About 170,000 people were eventually killed under this so-called Euthanasia programme, which also pioneered techniques and employed many of the people later used to kill Jews.
After the Warsaw Ghetto Uprising, the Ghetto was completely destroyed. Of the more than 56,000 Jews captured, about 7,000 were shot, and the remainder were deported to killing centers or concentration camps. This is a view of the remains of the ghetto, which the German SS dynamited to the ground. The Warsaw Ghetto only existed for a few years, and in that time, some 300,000 Polish Jews lost their lives there. #
Policies differed widely among Germany’s Balkan allies. In Romania it was primarily the Romanians themselves who slaughtered the country’s Jews. Toward the end of the war, however, when the defeat of Germany was all but certain, the Romanian government found more value in living Jews who could be held for ransom or used as leverage with the West. Bulgaria deported Jews from neighbouring Thrace and Macedonia, which it occupied, but government leaders faced stiff opposition to the deportation of native Bulgarian Jews, who were regarded as fellow citizens.
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]
