When the 322nd Rifle Division of the Red Army liberated Auschwitz on 27 January 1945, the soldiers found 7,500 prisoners alive and over 600 corpses.[247][248] Auschwitz II-Birkenau was liberated at around 3:30 p.m., and the main camp (Auschwitz I) two hours later.[249] Items found by the Soviet soldiers included 370,000 men's suits, 837,000 women's garments, and 7.7 tonnes (8.5 short tons) of human hair.[247][248] Primo Levi described seeing the first four Russian soldiers on horseback approach the camp at Monowitz, where he had been in the sick bay. The soldiers threw "strangely embarrassed glances at the sprawling bodies, at the battered huts and at us few still alive ...":[250]
Measuring 270 by 490 metres (890 ft × 1,610 ft), the camp was larger than Auschwitz I. By the end of 1944, it housed 60 barracks measuring 17.5 by 8 metres (57 ft × 26 ft), each with a day room and a sleeping room containing 56 three-tiered wooden bunks.[58] IG Farben paid the SS three or four Reichsmark for nine- to eleven-hour shifts from each worker.[59] In 1943–1944, about 35,000 inmates worked at the plant; 23,000 (32 a day on average) died as a result of malnutrition, disease, and the workload.[60] Deaths and transfers to Birkenau reduced the population by nearly a fifth each month;[61] site managers constantly threatened inmates with the gas chambers.[59] In addition to the Auschwitz inmates, who comprised a third of the work force, IG Auschwitz employed slave laborers from all over Europe.[62] When the camp was liquidated in January 1945, 9,054 out of the 9,792 inmates were Jews.[63]
Although not ordered to take part, psychiatrists and many psychiatric institutions were involved in the planning and carrying out of Aktion T4 at every stage.[103] After protests from the German Catholic and Protestant churches, Hitler ordered the cancellation of the T4 program in August 1941,[104] although the disabled and mentally ill continued to be killed until the end of the war.[102] The medical community regularly received bodies and body parts for research. Eberhard Karl University received 1,077 bodies from executions between 1933 and 1945. The neuroscientist Julius Hallervorden received 697 brains from one hospital between 1940 and 1944: "I accepted these brains of course. Where they came from and how they came to me was really none of my business."[105]

Before and after the March 1933 Reichstag elections, the Nazis intensified their campaign of violence against opponents.[77] They set up concentration camps for extrajudicial imprisonment.[78] One of the first, at Dachau, opened on 9 March 1933.[79] Initially the camp contained mostly Communists and Social Democrats.[80] Other early prisons were consolidated by mid-1934 into purpose-built camps outside the cities, run exclusively by the SS.[81] The initial purpose of the camps was to serve as a deterrent by terrorizing Germans who did not conform.[82]

In the fall of that year the Płaszów work camp opened nearby, and by February 1943 it was under the command of the notoriously sadistic SS officer Amon Göth, who would be executed after the war. Capitalizing on the officer’s appetite for drink and other luxury items available mainly on the black market, Schindler cultivated his friendship by ensuring a constant stream of them to the villa from which he oversaw the camp. Schindler thus managed to prevail upon Göth to create a separate camp for his Jewish workers, where they were free of the abuses suffered at Płaszów. Though Schindler’s motivations prior to this point are unclear, many scholars interpret his efforts to extricate his workers from Płaszów as indication that his concern for them was not purely financial.
Holocaust, Hebrew Shoʾah (“Catastrophe”), Yiddish and Hebrew Ḥurban (“Destruction”), the systematic state-sponsored killing of six million Jewish men, women, and children and millions of others by Nazi Germany and its collaborators during World War II. The Germans called this “the final solution to the Jewish question.” Yiddish-speaking Jews and survivors in the years immediately following their liberation called the murder of the Jews the Ḥurban, the word used to describe the destruction of the First Temple in Jerusalem by the Babylonians in 586 bce and the destruction of the Second Temple by the Romans in 70 ce. Shoʾah (“Catastrophe”) is the term preferred by Israelis and the French, most especially after Claude Lanzmann’s masterful 1985 motion picture documentary of that title. It is also preferred by people who speak Hebrew and by those who want to be more particular about the Jewish experience or who are uncomfortable with the religious connotations of the word Holocaust. Less universal and more particular, Shoʾah emphasizes the annihilation of the Jews, not the totality of Nazi victims. More particular terms also were used by Raul Hilberg, who called his pioneering work The Destruction of the European Jews, and Lucy S. Dawidowicz, who entitled her book on the Holocaust The War Against the Jews. In part she showed how Germany fought two wars simultaneously: World War II and the racial war against the Jews. The Allies fought only the World War. The word Holocaust is derived from the Greek holokauston, a translation of the Hebrew word ʿolah, meaning a burnt sacrifice offered whole to God. This word was chosen because in the ultimate manifestation of the Nazi killing program—the extermination camps—the bodies of the victims were consumed whole in crematoria and open fires.

Sanitary facilities for prisoners at Auschwitz-Birkenau were extremely poor. It was impossible for inmates to keep clean or have a change of clothes.  For the first two years of the camp’s existence, the prisoners had no access to water for washing. When there was later water, it was not clean. Prisoners, therefore, spent their existence in the camp dirty and in filthy clothes, which increased the likelihood of them contracting infections and diseases.
Camp commandant Rudolf Höss was arrested by the British at a farm near Flensburg, Germany, on 11 March 1946, where he had been working under the pseudonym Franz Lang.[262] He was imprisoned in Heide, then transferred to Minden for interrogation, part of the British occupation zone. From there he was taken to Nuremberg to testify for the defense in the trial of SS-Obergruppenführer Ernst Kaltenbrunner. Höss was straightforward about his own role in the mass murder and said he had followed the orders of Heinrich Himmler.[263][g] Extradited to Poland on 25 May 1946,[264] he wrote his memoirs in custody, first published in Polish in 1951 then in German in 1958 as Kommandant in Auschwitz.[265] His trial before the Supreme National Tribunal in Warsaw opened on 11 March 1947; he was sentenced to death on 2 April and hanged in Auschwitz I, near crematorium I, on 16 April.[266]
The Auschwitz camp complex has survived largely unchanged since its liberation in January 1945. The remaining camp buildings, structures and infrastructure are a silent witness to history, bearing testimony of the crime of genocide committed by the German Nazis. They are an inseparable part of a death factory organized with precision and ruthless consistency. The attributes that sustain the Outstanding Universal Value of the property are truthfully and credibly expressed, and fully convey the value of the property.
The prisoners put up various forms of resistance to the tyranny of the camp. Resistance organisations helped inmates to obtain medicine and food, documented Nazi crimes, supported attempts to escape and sabotage, tried to put political prisoners into positions of responsibility, and prepared for an uprising. A total of 667 prisoners escaped from Auschwitz, but 270 of them were caught in the vicinity of the camp and immediately executed. The best-known escape was that of two Slovak Jews, Alfred Wetzler and Walter Rosenberg (Rudolf Vrba) (link in Czech). They managed to cross into Slovakia and to tell Jewish leaders - and through them the world - about the terrible reality of Auschwitz, about which they wrote an extensive report. On the 7th of October 1944, there was an uprising by the Sonderkommando working in the gas chambers. The prisoners managed to destroy one of the gas chambers, and thus to hinder the extermination process. All the rebels died. A group of young female prisoners was also executed for having smuggled gunpowder to the rebels from the factory in Monowitz.

"The persecution of Jews in occupied Poland meant that we could see horror emerging gradually in many ways. In 1939, they were forced to wear Jewish stars, and people were herded and shut up into ghettos. Then, in the years '41 and '42 there was plenty of public evidence of pure sadism. With people behaving like pigs, I felt the Jews were being destroyed. I had to help them. There was no choice."

Life within Nazi concentration camps was horrible. Prisoners were forced to do hard physical labor and given little food. Prisoners slept three or more to a crowded wooden bunk; bedding was unheard of. Torture within the concentration camps was common and deaths were frequent. At a number of concentration camps, Nazi doctors conducted medical experiments on prisoners against their will.

The photo above shows the gate house which is the main entrance into Birkenau, also known as the Auschwitz II concentration camp. Beginning around the middle of May 1944, freight trains that were 40 to 50 cars long rolled through this gate, day and night, bringing thousands of Hungarian Jews to be gassed at the four Birkenau gas chambers. The prisoners called it the "Gate of Death."
After WWII had ended, photographs of the Holocaust stunned the public. Newspapers in the United States had reported on the oppression of the Jews in Germany during the war. In 1942, many newspapers were writing details of the Holocaust, but these stories were short and were not widely read. In 1943, after sources had confirmed the killings of at least two million Jews in concentration camps across Europe a Gallup poll found that less than half of Americans believed these reports to be true; 28% thought they were “just a rumor”. The reports were unconfirmed and sometimes denied by the United States government.
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 history of Auschwitz-Birkenau as an extermination center is complex. From late 1941 to October 1942, the mortuary at Auschwitz main camp, which was already equipped with a crematorium, was adapted as a gas chamber. It measured approximately 835 square feet. In the spring of 1942, two provisional gas chambers at Birkenau were constructed out of peasant huts, known as the 'bunkers'.
Oscar Schindler was all that stood between them and death at the hands of the Nazis. A man all too human, full of flaws like the rest of us. The unlikeliest of all role models - a Nazi, a womanisor, a war profiteer. An ordinary man who answered the call of conscience. Even in the worst of circumstances Oscar Schindler did extraordinary things, matched by no one. He remained true to his Jews, the workers he referred to as my children. He kept the SS out and everyone alive.
The early 1950s literature transformed blitzkrieg into a historical military doctrine, which carried the signature of Liddell Hart and Guderian. The main evidence of Liddell Hart's deceit and "tendentious" report of history can be found in his letters to Erich von Manstein, Heinz Guderian and the relatives and associates of Erwin Rommel. Liddell Hart, in letters to Guderian, "imposed his own fabricated version of blitzkrieg on the latter and compelled him to proclaim it as original formula".[145][146] Kenneth Macksey found Liddell Hart's original letters to Guderian in the General's papers, requesting that Guderian give him credit for "impressing him" with his ideas of armoured warfare. When Liddell Hart was questioned about this in 1968 and the discrepancy between the English and German editions of Guderian's memoirs, "he gave a conveniently unhelpful though strictly truthful reply. ('There is nothing about the matter in my file of correspondence with Guderian himself except...that I thanked him...for what he said in that additional paragraph'.)".[147]

A column of inmates reached the Gross-Rosen complex. Throughout February, the terribly overcrowded main camp at Gross-Rosen was cleared, and all 44,000 inmates were moved further west. An unknown number died in this last journey.[244] In March 1945, Himmler ordered that no more prisoners should be killed, as he hoped to use them as hostages in negotiations with the Allies.[245] Approximately 20,000 Auschwitz prisoners made it to Bergen-Belsen, where they were liberated by the British in April 1945.[246]

Political dissidents, trade unionists, and Social Democrats were among the first to be arrested and incarcerated in concentration camps. Under the Weimar government, centuries-old prohibitions against homosexuality had been overlooked, but this tolerance ended violently when the SA (Storm Troopers) began raiding gay bars in 1933. Homosexual intent became just cause for prosecution. The Nazis arrested German and Austrian male homosexuals—there was no systematic persecution of lesbians—and interned them in concentration camps, where they were forced to wear special yellow armbands and later pink triangles. The goal of persecuting male homosexuals was either for reeducation—what might now be called conversion therapy—or punishment. Jehovah’s Witnesses were a problem for the Nazis because they refused to swear allegiance to the state, register for the draft, or utter the words “Heil Hitler.” As a result, the Nazis imprisoned many of the roughly 20,000 Jehovah’s Witnesses in Germany. They could be released from concentration camps if they signed a document renouncing their faith and promising not to proselytize. Few availed themselves of that option, preferring martyrdom to apostasy. Germans of African descent—many of whom, called “Rhineland bastards” by the Nazis, were the offspring of German mothers and French colonial African troops who had occupied the Rhineland after World War I—were also persecuted by the Nazis. Although their victimization was less systematic, it included forced sterilization and, often, internment in concentration camps. The fear was that they would “further pollute” and thereby diminish the race. The Nazis also singled out the Roma and Sinti, pejoratively known as Gypsies. They were the only other group that the Nazis systematically killed in gas chambers alongside the Jews. For the Roma and Sinti, too, racial pollution and their depiction as asocials was the justification for their persecution and murder.
In March 1941, Himmler visited Auschwitz and commanded its enlargement to hold 30,000 prisoners. The location of the camp, practically in the center of German-occupied Europe, and its convenient transportation connections and proximity to rail lines was the main thinking behind the Nazi plan to enlarge Auschwitz and begin deporting people here from all over Europe.
Jewish deportees arriving at Auschwitz-Birkenau immediately underwent selection. The SS staff chose some of the able-bodied for forced labor and sent the rest directly to the gas chambers, which were disguised as shower installations to mislead the victims. The belongings of all deportees were confiscated and sorted in the "Kanada" (Canada) warehouse for shipment back to Germany. Canada symbolized wealth to the prisoners.
Most troops were moved by half-track vehicles so there was no real need for roads though these were repaired so that they could be used by the Germans at a later date. Once a target had been taken, the Germans did not stop to celebrate victory; they moved on to the next target. Retreating civilians hindered any work done by the army being attacked. Those civilians fleeing the fighting were also attacked to create further mayhem.
The Soviets found 7,600 inmates in Auschwitz.[385] Some 60,000 prisoners were discovered at Bergen-Belsen by the British 11th Armoured Division;[386] 13,000 corpses lay unburied, and another 10,000 people died from typhus or malnutrition over the following weeks.[387] The BBC's war correspondent, Richard Dimbleby, described the scenes that greeted him and the British Army at Belsen, in a report so graphic the BBC declined to broadcast it for four days, and did so, on 19 April, only after Dimbleby had threatened to resign.[388]
In September 1939, the German army occupied the western half of Poland. German police soon forced tens of thousands of Polish Jews from their homes and into ghettoes, giving their confiscated properties to ethnic Germans (non-Jews outside Germany who identified as German), Germans from the Reich or Polish gentiles. Surrounded by high walls and barbed wire, the Jewish ghettoes in Poland functioned like captive city-states, governed by Jewish Councils. In addition to widespread unemployment, poverty and hunger, overpopulation made the ghettoes breeding grounds for disease such as typhus.
After some time off to recover in Zwittau, Schindler was promoted to second in command of his Abwehr unit and relocated with his wife to Ostrava, on the Czech-Polish border, in January 1939.[13] He was involved in espionage in the months leading up to Hitler's seizure of the remainder of Czechoslovakia in March. Emilie helped him with paperwork, processing and hiding secret documents in their apartment for the Abwehr office.[14] As Schindler frequently travelled to Poland on business, he and his 25 agents were in a position to collect information about Polish military activities and railways for the planned invasion of Poland.[15] One assignment called for his unit to monitor and provide information about the railway line and tunnel in the Jablunkov Pass, deemed critical for the movement of German troops.[16] Schindler continued to work for the Abwehr until as late as fall 1940, when he was sent to Turkey to investigate corruption among the Abwehr officers assigned to the German embassy there.[17]
