The first gassings at Auschwitz took place in early September 1941, when around 850 inmates—Soviet prisoners of war and sick Polish inmates—were killed with Zyklon B in the basement of block 11 in Auschwitz I. The building proved unsuitable, so gassings were conducted instead in crematorium I, also in at Auschwitz I, which operated until December 1942. There, more than 700 victims could be killed at once. Tens of thousands were killed in crematorium I. To keep the victims calm, they were told they were to undergo disinfection and de-lousing; they were ordered to undress outside, then were locked in the building and gassed. After its decommissioning as a gas chamber, the building was converted to a storage facility and later served as an SS air raid shelter. The gas chamber and crematorium were reconstructed after the war. Dwork and van Pelt write that a chimney was recreated; four openings in the roof were installed to show where the Zyklon B had entered; and two of the three furnaces were rebuilt with the original components.
The Allies believed that 'blitzkrieg' was dependent on new technology, such as tanks and dive-bombers © Shocked by their experience, the Allied military observers who had survived the fall of France attributed their defeat to the completely new form of warfare pioneered by the Wehrmacht - the blitzkrieg. Blitzkrieg seemed to be based around the pervasive use of new technology. After all, during the disastrous campaign in Belgium and France, it had seemed as if German tanks and aircraft were everywhere.
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. IG Farben paid the SS three or four Reichsmark for nine- to eleven-hour shifts from each worker. 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. Deaths and transfers to Birkenau reduced the population by nearly a fifth each month; site managers constantly threatened inmates with the gas chambers. In addition to the Auschwitz inmates, who comprised a third of the work force, IG Auschwitz employed slave laborers from all over Europe. When the camp was liquidated in January 1945, 9,054 out of the 9,792 inmates were Jews.
Auschwitz became one of the camps used for the mass extermination of Jews. In summer 1941, Heinrich Himmler gave orders to Auschwitz commander Rudolf Höß to build a centre at Auschwitz for the mass murder of Jews. In September 1941, the lethal effects of Zyklon B - a substance normally used for pest control - were first tested and verified there. Later, four large gas chambers were built at Birkenau, capable of killing up to six thousand people each day. The gas chambers were disguised as showers, meant to persuade the victims that these were disinfection measures which they had to undergo before they were sent to work in the camp.
Entrance is free, without a ticket, though donations are encouraged. Because of the large numbers of visitors entry to the Auschwitz-I site is exclusively on a guided group basis during the middle part of the day - as of 2019, between 10am and 12pm during December, between 10am and 1pm in November, January, February and March, between 10am and 4pm in April, May, September and October, and between 9am and 5pm in June, July and August.
In the aftermath of the Holocaust, many of the survivors found shelter in displaced persons camps administered by the Allied powers. Between 1948 and 1951, almost 700,000 Jews emigrated to Israel, including 136,000 Jewish displaced persons from Europe. Other Jewish displaced persons emigrated to the United States and other nations. The last camp for Jewish displaced persons closed in 1957.
During World War I, Fuller had been a staff officer attached to the new tank corps. He developed Plan 1919 for massive, independent tank operations, which he claimed were subsequently studied by the German military. It is variously argued that Fuller's wartime plans and post-war writings were an inspiration or that his readership was low and German experiences during the war received more attention. The German view of themselves as the losers of the war, may be linked to the senior and experienced officers' undertaking a thorough review, studying and rewriting of all their Army doctrine and training manuals.
The Holocaust was the murder by Nazi Germany of six million Jews. While the Nazi persecution of the Jews began in 1933, the mass murder was committed during World War II. It took the Germans and their accomplices four and a half years to murder six million Jews. They were at their most efficient from April to November 1942 – 250 days in which they murdered some two and a half million Jews. They never showed any restraint, they slowed down only when they began to run out of Jews to kill, and they only stopped when the Allies defeated them. More...
According to Polish historian Andrzej Strzelecki, the evacuation of the prisoners by the SS in January 1945 was one of the camp's "most tragic chapters". In mid-1944, about 130,000 prisoners were in Auschwitz when the SS moved around half of them to other concentration camps. In November 1944, with the Soviet Red Army approaching through Poland, Himmler ordered gassing operations to cease. The crematorium IV building was dismantled, and the Sonderkommando was ordered to remove evidence of the killings, including the mass graves. The SS destroyed written records, and in the final week before the camp's liberation, burned or demolished many of its buildings. The plundered goods from the "Canada" barracks at Birkenau, together with building supplies, were transported to the German interior. On 20 January, the overflowing warehouses were set ablaze. Crematoria II and III at Birkenau were blown up on 20 January and crematorium V six days later, just one day ahead of the Soviet attack.
The Holocaust was a 20th Century atrocity caused by men and women who were driven by hatred, ignorance and greed, Auschwitz is a reminder of what can happen if we let for one moment the fanatics/extremists and some elected politicians tell us that our way of life is threatened, we have a duty to our children and theirs to show them what really happens when hatred and discrimination is used as a weapon against your fellow man, It is a crime in itself to even deny the holocaust, there are no words to describe the pity I feel for those who lack any emotion or lack the intelligent to absorb the truth,
The musicians themselves were all too aware of their role as both accomplices and victims of the Nazi terror. For many of the women, being in the orchestra was demoralising and depressing. Although they were afforded the 'privilege' of increased rations, improved living quarters, and other 'benefits', many were disgusted by the pleasure that they gave to their tormenters. Fénelon and others describe with revulsion being forced to comfort the murderers by playing or singing their favourite pieces.
On 15 September 1935, the Reichstag passed the Nuremberg Laws, prohibiting marriages between Jews and people of Germanic extraction, extramarital relations between Jews and Germans, and the employment of German women under the age of 45 as domestic servants in Jewish households. The Reich Citizenship Law defined as citizens those of "German or kindred blood". Thus Jews and other minorities were stripped of their citizenship. By the start of World War II in 1939, around 250,000 of Germany's 437,000 Jews had emigrated to the United States, Palestine, the United Kingdom, and other countries.
Nolte's views were widely denounced. The debate between the "specifists" and "universalists" was acrimonious; the former feared debasement of the Holocaust and the latter considered it immoral to hold the Holocaust as beyond compare. In her book Denying the Holocaust (1993), Deborah Lipstadt viewed Nolte's position as a form of Holocaust denial, or at least "the same triumph of ideology over truth". Addressing Nolte's argument, Eberhard Jäckel wrote in Die Zeit in September 1986 that "never before had a state, with the authority of its leader, decided and announced that a specific group of humans, including the elderly, women, children and infants, would be killed as quickly as possible, then carried out this resolution using every possible means of state power".[h] Despite the criticism of Nolte, Dan Stone wrote in 2010 that the Historikerstreit put "the question of comparison" on the agenda. He argued that the idea of the Holocaust as unique has been overtaken by attempts to place it within the context of early-20th-century Stalinism, ethnic cleansing, and the Nazis' intentions for post-war "demographic reordering", particularly the Generalplan Ost, the plan to kill tens of millions of Slavs to create living space for Germans. The specifist position continued nevertheless to inform the views of many specialists. Richard J. Evans argued in 2015:
Oskar Schindler is a vainglorious and greedy German businessman who becomes an unlikely humanitarian amid the barbaric German Nazi reign when he feels compelled to turn his factory into a refuge for Jews. Based on the true story of Oskar Schindler who managed to save about 1100 Jews from being gassed at the Auschwitz concentration camp, it is a testament to the good in all of us. Written by Harald Mayr
Conventional wisdom traces blitzkrieg, “lightning war,” to the development in Germany between 1918 and 1939 of a body of doctrine using mobility to prevent repetition of the attritional deadlock of World War I. Soldiers such as Hans von Seeckt and Heinz Guderian allegedly perceived more clearly than their counterparts elsewhere in Europe the military potential of the internal-combustion engine combined with modern communications technology. Large formations moving on tracks and wheels, directed by radios, could rupture an enemy’s front and so disorganize its rear that countermeasures would be paralyzed. First tested in Poland, the concept reached perihelion in France and the Low Countries in 1940, when in less than six weeks the German army crushed the combined forces of four nations. Applied a year later against the Soviet Union, blitzkrieg purportedly brought the Wehrmacht to the gates of Moscow in six months. Some accounts insist that only Adolf Hitler’s incompetent interference tipped the war’s balance so far against Germany that even blitzkrieg’s most sophisticated refinements could do no more than stave off the Reich’s collapse.
"...(t)hroughout ( the Polish Campaign), the employment of the mechanized units revealed the idea that they were intended solely to ease the advance and to support the activities of the infantry....Thus, any strategic exploitation of the armored idea was still-born. The paralysis of command and the breakdown of morale were not made the ultimate aim of the ... German ground and air forces, and were only incidental by-products of the traditional maneuvers of rapid encirclement and of the supporting activities of the flying artillery of the Luftwaffe, both of which had has their purpose the physical destruction of the enemy troops. Such was the Vernichtungsgedanke of the Polish campaign."
Similarly, in Ordinary Men (1992), Christopher Browning examined the deeds of German Reserve Police Battalion 101 of the Ordnungspolizei ("order police"), used to commit massacres and round-ups of Jews, as well as mass deportations to the death camps. The members of the battalion were middle-aged men of working-class background from Hamburg, who were too old for regular military duty. They were given no special training. During the murder of 1,500 Jews from Józefów in Poland, their commander allowed them to opt out of direct participation. Fewer than 12 men out of a battalion of 500 did so. Influenced by the Milgram experiment on obedience, Browning argued that the men killed out of peer pressure, not bloodlust.
Hitler’s worldview revolved around two concepts: territorial expansion (that is, greater Lebensraum—“living space”—for the German people) and racial supremacy. After World War I the Allies denied Germany colonies in Africa, so Hitler sought to expand German territory and secure food and resources—scarce during World War I—in Europe itself. Hitler viewed the Jews as racial polluters, a cancer on German society in what has been termed by Holocaust survivor and historian Saul Friedländer “redemptive anti-Semitism,” focused on redeeming Germany from its ills and ridding it of a cancer on the body politic. Historian Timothy Snyder characterized the struggle as even more elemental, as “zoological,” and “ecological,” a struggle of the species. Hitler opposed Jews for the values they brought into the world. Social justice and compassionate assistance to the weak stood in the way of what he perceived as the natural order, in which the powerful exercise unrestrained power. In Hitler’s view, such restraint on the exercise of power would inevitably lead to the weakening, even the defeat, of the master race.
Also in 1993, the United States Holocaust Memorial Council posthumously presented the Museum's Medal of Remembrance to Schindler. Rarely presented, this medal honors deserving recipients for extraordinary deeds during the Holocaust and in the cause of Remembrance. Emilie Schindler accepted the medal on behalf of her ex-husband at a ceremony in the Museum's Hall of Remembrance.
The existing legal system provides appropriate tools for the effective protection and management of the property. The Museum Council, whose members are appointed by the Minister of Culture and National Heritage, supervises the performance of the Museum’s duties regarding its collections, in particular the execution of its statutory tasks. In addition, the International Auschwitz Council acts as a consultative and advisory body to the Prime Minister of the Republic of Poland on the protection and management of the site of the former Auschwitz Birkenau camp and other places of extermination and former concentration camps situated within the present territory of Poland.
Oscar Schindler rose to the highest level of humanity, walked through the bloody mud of the Holocaust without soiling his soul, his compassion, his respect for human life - and gave his Jews a second chance at life. He miraculously managed to do it and pulled it off by using the very same talents that made him a war profiteer - his flair for presentation, bribery, and grand gestures.
Most of the Jewish ghettos of General Government were liquidated in 1942–1943, and their populations shipped to the camps for extermination.[t] About 42,000 Jews were shot during the Operation Harvest Festival on 3–4 November 1943. At the same time, rail shipments arrived regularly from western and southern Europe at the extermination camps. Few Jews were shipped from the occupied Soviet territories to the camps: the killing of Jews in this zone was mostly left in the hands of the SS, aided by locally recruited auxiliaries.[u]
When Germany invaded Poland in September 1939, triggering World War II, Adolf Hitler ordered that the Polish leadership and intelligentsia be destroyed. 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. 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. Two years later, in June 1941, in an attempt to obtain new territory, Hitler invaded the Soviet Union.
The 15 men present at Wannsee included Adolf Eichmann (head of Jewish affairs for the RSHA and the man who organized the deportation of Jews), Heinrich Müller (head of the Gestapo), and other party leaders and department heads. Thirty copies of the minutes were made. Copy no. 16 was found by American prosecutors in March 1947 in a German Foreign Office folder. Written by Eichmann and stamped "Top Secret", the minutes were written in "euphemistic language" on Heydrich's instructions, according to Eichmann's later testimony. The conference had several purposes. Discussing plans for a "final solution to the Jewish question" ("Endlösung der Judenfrage"), and a "final solution to the Jewish question in Europe" ("Endlösung der europäischen Judenfrage"), it was intended to share information and responsibility, coordinate efforts and policies ("Parallelisierung der Linienführung"), and ensure that authority rested with Heydrich. There was also discussion about whether to include the German Mischlinge (half-Jews). Heydrich told the meeting: "Another possible solution of the problem has now taken the place of emigration, i.e. the evacuation of the Jews to the East, provided that the Fuehrer gives the appropriate approval in advance." He continued:
According to the Yad Vashem Holocaust Martyrs' and Heroes' Remembrance Authority in Jerusalem, "[a]ll the serious research" confirms that between five and six million Jews died. Early postwar calculations were 4.2 to 4.5 million from Gerald Reitlinger; 5.1 million from Raul Hilberg; and 5.95 million from Jacob Lestschinsky. In 1986 Lucy S. Dawidowicz used the pre-war census figures to estimate 5.934 million. Yehuda Bauer and Robert Rozett in the Encyclopedia of the Holocaust (1990) estimated 5.59–5.86 million. A 1996 study led by Wolfgang Benz suggested 5.29 to 6.2 million, based on comparing pre- and post-war census records and surviving German documentation on deportations and killings. Martin Gilbert arrived at a minimum of 5.75 million. The figures include over one million children.
Nevertheless, despite the lack of access to clean water, soap and a change of clothes, many prisoners continued to go through the motions of washing each morning. This was because, even though it was not possible to carry out the activities of a normal life, it was extremely important to preserve the ‘spirit’ of life, not to give up. This can be seen so vividly in the writings of Primo Levi, a survivor of Auschwitz, who went on to become a distinguished writer,
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. Auschwitz II-Birkenau was liberated at around 3:30 p.m., and the main camp (Auschwitz I) two hours later. 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. 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 ...":
The Holocaust (also called Ha-Shoah in Hebrew) refers to the period from January 30, 1933 - when Adolf Hitler became chancellor of Germany - to May 8, 1945, when the war in Europe officially ended. During this time, Jews in Europe were subjected to progressively harsher persecution that ultimately led to the murder of 6,000,000 Jews (1.5 million of these being children) and the destruction of 5,000 Jewish communities. These deaths represented two-thirds of European Jewry and one-third of all world Jewry.
Not long after acquiring his “Emalia” factory - which produced enamel goods and munitions to supply the German front - the removal of Jews to death camps began in earnest. Schindler's Jewish accountant put him in touch with the few Jews with any remaining wealth. They invested in his factory, and in return they would be able to work there and perhaps be spared. He was persuaded to hire more Jewish workers, designating their skills as “essential,” paying off the Nazis so they would allow them to stay in Kraków. Schindler was making money, but everyone in his factory was fed, no-one was beaten, no-one was killed. It became an oasis of humanity in a desert of moral torpor.
^ The escapees included 396 Polish men and 10 Polish women; 164 men from the Soviet Union (including 50 prisoners of war), and 15 women; 112 Jewish men and three Jewish women; 36 Romani/Sinti men and two women; 22 German men and nine women; 19 Czech men and four women; two Austrians; one Yugoslav woman and one man; and 15 other men and one woman.
The train station of Oświęcim is about 2 km from the museum and there are public town buses connecting them (2.70 zł). There are several local trains each day, both from Kraków and from Katowice, about each 1.5-2 hours. The trip to or from Kraków central station takes a leisurely 2 hours, as the train goes slowly and stops frequently. It costs 9.50 zł.
The Auschwitz complex was divided in three major camps: Auschwitz I main camp or Stammlager; Auschwitz II, or Birkenau, established on October 8th, 1941 as a 'Vernichtungslager' (extermination camp); Auschwitz III or Monowitz, established on May 31th, 1942 as an 'Arbeitslager' or work camp; also several sub-camps. There were up to seven gas chambers using Zyklon-B poison gas and three crematoria. Auschwitz II included a camp for new arrivals and those to be sent on to labor elsewhere; a Gypsy camp; a family camp; a camp for holding and sorting plundered goods and a women's camp. Auschwitz III provided slave labor for a major industrial plant run by I G Farben for producing synthetic rubber (see Blechhammer). Highest number of inmates, including sub-camps: 155,000. The estimated number of deaths: 2.1 to 2.5 million killed in gas chambers, of whom about 2 million were Jews, and Poles, Gypsies and Soviet POWs. About 330,000 deaths from other causes.
The Reichswehr and Red Army collaborated in wargames and tests in Kazan and Lipetsk beginning in 1926. During this period, the Red Army was developing the theory of Deep operations, which would guide Red Army doctrine throughout World War II. Set within the Soviet Union, these two centers were used to field test aircraft and armored vehicles up to the battalion level, as well as housing aerial and armored warfare schools through which officers were rotated. This was done in the Soviet Union, in secret, to evade the Treaty of Versailles's occupational agent, the Inter-Allied Commission.
Overy wrote that blitzkrieg as a "coherent military and economic concept has proven a difficult strategy to defend in light of the evidence". Milward's theory was contrary to Hitler's and German planners' intentions. The Germans, aware of the errors of the First World War, rejected the concept of organising its economy to fight only a short war. Therefore, focus was given to the development of armament in depth for a long war, instead of armament in breadth for a short war. Hitler claimed that relying on surprise alone was "criminal" and that "we have to prepare for a long war along with surprise attack". During the winter of 1939–40, Hitler demobilised many troops from the army to return as skilled workers to factories because the war would be decided by production, not a quick "Panzer operation".
Modern blitzkrieg was introduced by the German Army as a rational response to the stagnant trench warfare that characterized most of the fighting on the Western Front during World War I. Battles like Verdun or Passchendaele proved the war was nothing more than a meat grinder, and attacks from both sides only further proved the futility of the conflict.
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.
These techniques were used to great effect in 1939, when the Polish Army was destroyed in a series of encirclement battles. In May 1940 Hitler attacked France, his panzer divisions smashing through slow-moving French formations and cutting off the British Expeditionary Force at Dunkirk. Spectacular success was also achieved during the invasion of the Soviet Union in 1941 and large numbers of Soviet troops were captured.
During the era of the Holocaust, German authorities also targeted other groups because of their perceived racial and biological inferiority: Roma (Gypsies), people with disabilities, and some of the Slavic peoples (Poles, Russians, and others). Other groups were persecuted on political, ideological, and behavioral grounds, among them Communists, Socialists, Jehovah's Witnesses, and homosexuals.
From this moment on, the Nazi regime adopted hundreds of laws restricting the rights and liberties of the Jewish people. Jews were expelled from the civil service and barred from entering particular professions, stripped of their citizenship, and forbidden from intermarrying or even having a relationship with anyone of “German or German-related blood”.
After the start of World War II, Adolf Hitler (1889-1945), the chancellor of Germany from 1933 to 1945, implemented a policy that came to be known as the “Final Solution.” Hitler was determined not just to isolate Jews in Germany and countries annexed by the Nazis, subjecting them to dehumanizing regulations and random acts of violence. Instead, he became convinced that his “Jewish problem” would be solved only with the elimination of every Jew in his domain, along with artists, educators, Gypsies, communists, homosexuals, the mentally and physically handicapped and others deemed unfit for survival in Nazi Germany.
In Autumn 1943, the camp administration was reorganized following a corruption scandal. By the end of 1943, the prisoner population of Auschwitz main camp, Birkenau, Monowitz and other sub-camps was over 80,000: 18,437 in the main camp, 49,114 in Birkenau, and 13,288 at Monowitz where I G Farben had its synthetic rubber plant. Up to 50,000 prisoners were scattered around 51 sub-camps such as Rajsko, an experimental agricultural station, and Gleiwitz, a coal mine (see The List of the Camps for a complete list of those sub-camps).
Auschwitz, also known as Auschwitz-Birkenau, opened in 1940 and was the largest of the Nazi concentration and death camps. Located in southern Poland, Auschwitz initially served as a detention center for political prisoners. However, it evolved into a network of camps where Jewish people and other perceived enemies of the Nazi state were exterminated, often in gas chambers, or used as slave labor. Some prisoners were also subjected to barbaric medical experiments led by Josef Mengele (1911-79). During World War II (1939-45), more than 1 million people, by some accounts, lost their lives at Auschwitz. In January 1945, with the Soviet army approaching, Nazi officials ordered the camp abandoned and sent an estimated 60,000 prisoners on a forced march to other locations. When the Soviets entered Auschwitz, they found thousands of emaciated detainees and piles of corpses left behind.
Under the Nuremberg Laws, Jews became routine targets for stigmatization and persecution. This culminated in Kristallnacht, or the “night of broken glass” in November 1938, when German synagogues were burned and windows in Jewish shops were smashed; some 100 Jews were killed and thousands more arrested. From 1933 to 1939, hundreds of thousands of Jews who were able to leave Germany did, while those who remained lived in a constant state of uncertainty and fear.
The invasion of France consisted of two phases, Operation Yellow (Fall Gelb) and Operation Red. Yellow opened with a feint conducted against the Netherlands and Belgium by two armoured corps and paratroopers. Three days later, the main effort of Panzer Group von Kleist attacked through the Ardennes and achieved a breakthrough with air support. The group raced to the coast of the English Channel, dislodging the British Expeditionary Force, Belgian Army, and some divisions of the French Army. The motorized units initially advanced far beyond the following divisions. When the German motorized forces were met with a counterattack at the Battle of Arras (1940), British tanks with heavy armour (Matilda I & IIs) created a brief panic in the German High Command. The motorized forces were halted outside the port city of Dunkirk which was being used to evacuate the Allied forces. Hermann Göring had promised his Luftwaffe would complete the job but aerial operations did not prevent the evacuation of the majority of Allied troops (which the British named Operation Dynamo); some 330,000 French and British. Operation Red then began with XV Panzer Corps attacking towards Brest and XIV Panzer Corps attacking south, east of Paris, towards Lyon, and XIX Panzer Corps completing the encirclement of the Maginot Line. The defending forces were hard pressed to organize any sort of counter-attack. The French forces were continually ordered to form new lines along rivers, often arriving to find the German forces had already passed them.
Around 7,000 SS personnel were posted to Auschwitz during the war. Of these, 4 percent of SS personnel were officers and 26 percent were non-commissioned officers, while the remainder were rank-and-file members. Camp guards were members of the SS-Totenkopfverbände (Death's Head Units). Approximately three in four SS personnel worked in security. Others worked in the medical or political departments, in the camp headquarters, or in the economic administration, which was responsible for the property of dead prisoners. SS personnel at the camp included 200 women, who worked as guards, nurses, or messengers. About 120 SS personnel were assigned to the gas chambers and lived on site at the crematoria.
The Jews killed represented around one third of the world population of Jews, and about two-thirds of European Jewry, based on an estimate of 9.7 million Jews in Europe at the start of the war. Much of the uncertainty stems from the lack of a reliable figure for the number of Jews in Europe in 1939, numerous border changes that make avoiding double-counting of victims difficult, lack of accurate records from the perpetrators, and uncertainty about whether deaths occurring months after liberation, but caused by the persecution, should be counted.
