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.[391] Early postwar calculations were 4.2 to 4.5 million from Gerald Reitlinger;[392] 5.1 million from Raul Hilberg; and 5.95 million from Jacob Lestschinsky.[393] In 1986 Lucy S. Dawidowicz used the pre-war census figures to estimate 5.934 million.[394] Yehuda Bauer and Robert Rozett in the Encyclopedia of the Holocaust (1990) estimated 5.59–5.86 million.[395] 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.[391] Martin Gilbert arrived at a minimum of 5.75 million.[396] The figures include over one million children.[397]
After Germany invaded Poland in 1939, Oskar Schindler set up an enamelware factory in Krakow that used a combination of Jewish workers interred by the Germans and free Polish workers. His initial interest, of course, was to make money. But as time went on, he grew to care about his Jewish workers, particularly those with whom he came into contact on a daily basis. In addition, helping Jews became a way to fight against what he viewed as disastrous and brutal policies emanating from Adolf Hitler and the SS.
Heinz Guderian is widely regarded as being highly influential in developing the military methods of warfare used by Germany's tank men at the start of the Second World War. This style of warfare brought manoeuvre back to the fore, and placed an emphasis on the offensive. This style, along with the shockingly rapid collapse in the armies that opposed it, came to be branded as blitzkrieg warfare.[15]
British theorists J.F.C. Fuller and Captain B. H. Liddell Hart have often been associated with blitzkrieg's development, though this is a matter of controversy. The British War Office did permit an Experimental Mechanised Force, formed on 1 May 1927, that was wholly motorized including self propelled artillery and motorised engineers. It is argued that Guderian, a critical figure in blitzkrieg's conception, drew some of his inspiration from Liddell Hart. This was based on a paragraph in the English edition of Guderian's autobiography in which he credits Liddell Hart. In opposition, it is argued that Liddell Hart, as editor of the autobiography's English edition, wrote that paragraph himself or, more broadly, that his influence on Guderian was not as significant as held. Fuller's influence is less clear. During the war, he developed plans for massive, independent tank operations and was subsequently studied by the German leadership. 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.
Despite, wide reporting of Holocaust atrocities including gas chambers, many prominent analysts doubted the authenticity of these reports. Prominently, Roger Allen, a member of the British Foreign Office discounted intelligence reports on the use of gas chambers in Polish extermination camps because he could “never understand what the advantage of a gas chamber over a simple machine gun or over starving people would be.”
In the 1960s, Alan Milward developed a theory of blitzkrieg economics, that Germany could not fight a long war and chose to avoid comprehensive rearmament and armed in breadth, to win quick victories. Milward described an economy positioned between a full war economy and a peacetime economy.[124][125] The purpose of the blitzkrieg economy was to allow the German people to enjoy high living standards in the event of hostilities and avoid the economic hardships of the First World War.[126]
When in August 1944 his factory was decommissioned, Schindler successfully petitioned to have it moved to Brnĕnec (Brünnlitz) in the Sudetenland, close to his hometown. Schindler and his associates composed a list of Jewish workers that he deemed essential for the new factory and submitted it for approval to the Jewish labour office. (With several versions of the list known, it is difficult to determine how many people were ultimately selected.) Though those chosen were diverted for a time to other concentration camps, Schindler intervened, ensuring that 700 men and 300 women eventually arrived at Brnĕnec. They were later joined by 100 more Jews who had been transported from another concentration camp by the Nazis and abandoned in train cars in Brnĕnec. Those who reached the camp spent the remaining months of the war manufacturing munitions that were rigged to fail. A final head count compiled at this time listed 1,098 Jews at the camp.
SS officers, including the infamous Dr. Josef Mengele, would conduct selections among these lines, sending most victims to one side and thus condemning them to death in the gas chambers. A minority was sent to the other side, destined for forced labor. Those who were sent to their deaths were killed that same day and their corpses were burnt in the crematoria. Those not sent to the gas chambers were taken to “quarantine,” where their hair was shaved, striped prison uniforms distributed, and registration took place. Prisoners’ individual registration numbers were tattooed onto their left arm.
Information about Auschwitz became available to the Allies as a result of reports by Captain Witold Pilecki of the Polish Home Army (Armia Krajowa), who volunteered to be imprisoned there in 1940. As "Thomasz Serfiński", he allowed himself to be arrested in Warsaw and spent 945 days in the camp, from 22 September 1940[199] until his escape on 27 April 1943. Michael Fleming writes that Pilecki was instructed to sustain morale, organize food, clothing and resistance, prepare to take over the camp if possible, and smuggle information out to the Polish military.[200] Pilecki called his resistance movement Związek Organizacji Wojskowej (ZOW, "Union of Military Organization").[199]
In chambers II and III, the killings took place in underground rooms, and the corpses were carried to the five ovens by an electrically operated lift. Before cremation gold teeth and any other valuables, such as rings, were removed from the corpses. In IV and V the gas chambers and ovens were on the same level, but the ovens were so poorly built and the usage was so great that they repeatedly malfunctioned and had to be abandoned. The corpses were finally burned outside, in the open, as in 1943. Jewish Sonderkommandos worked the crematoria under SS supervision.

When Germany invaded Poland in September 1939, it gained control of about 2 million Jews in the occupied territory. The rest of Poland was occupied by the Soviet Union, which had control of the rest of Poland's pre-war population of 3.3–3.5 million Jews.[141] German plans for Poland included expelling gentile Poles from large areas, confining Jews, and settling Germans on the emptied lands.[142] The Germans initiated a policy of sending Jews from all territories they had recently annexed (Austria, Czechoslovakia, and western Poland) to the central section of Poland, which they called the General Government. There, the Jews were concentrated in ghettos in major cities,[143] chosen for their railway lines to facilitate later deportation.[144] Food supplies were restricted, public hygiene was difficult, and the inhabitants were often subjected to forced labor.[145] In the work camps and ghettos, at least half a million Jews died of starvation, disease, and poor living conditions.[146] Jeremy Black writes that the ghettos were not intended, in 1939, as a step towards the extermination of the Jews. Instead, they were viewed as part of a policy of creating a territorial reservation to contain them.[147][l]
Eight hundred to a thousand people were crammed into the superimposed compartments of each barracks. Unable to stretch out completely, they slept there both lengthwise and crosswise, with one man's feet on another's head, neck, or chest. Stripped of all human dignity, they pushed and shoved and bit and kicked each other in an effort to get a few more inches' space on which to sleep a little more comfortably. For they did not have long to sleep.[122]
The Auschwitz registry (Hauptbücher) shows that 20,946 Roma were registered prisoners,[145] and another 3,000 are thought to have entered unregistered.[146] On 22 March 1943, one transport of 1,700 Polish Sinti and Roma was gassed on arrival because of illness, as was a second group of 1,035 on 25 May 1943.[145] The SS tried to liquidate the camp on 16 May 1944, but the Roma fought them, armed with knives and iron pipes, and the SS retreated. Shortly after this, the SS removed nearly 2,908 from the family camp to work, and on 2 August 1944 gassed the other 2,897. Ten thousand remain unaccounted for.[147]
Shortly after Hitler came to power, the Reichstag building, seat of the German parliament, burnt down. Communists were blamed for setting the fire and Hindenburg declared a state of emergency, passing the Reichstag Fire Decree that suspended basic rights like trial by jury. The German Communist Party was suspended and over 4,000 members were detained without trial. The next month, Hitler’s cabinet passed the Enabling Act which allowed him to enact laws without the consent of the parliament for four years, effectively transforming the German government into a de facto Nazi dictatorship.
Some ghettos were initially open, which meant that Jews could leave the area during the daytime but had to be back by a curfew. Later, all ghettos became closed, meaning that Jews were not allowed to leave under any circumstances. Major ghettos were located in the cities of Polish cities of Bialystok, Lodz, and Warsaw. Other ghettos were found in present-day Minsk, Belarus; Riga, Latvia; and Vilna, Lithuania. The largest ghetto was in Warsaw. At its peak in March 1941, some 445,000 were crammed into an area just 1.3 square miles in size.
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.
Historians differ on the date of the decision to murder Jews systematically, the so-called “final solution to the Jewish question.” There is debate about whether there was one central decision or a series of regional decisions in response to local conditions. In either case, when Germany attacked the Soviet Union, its former ally, in June of 1941, the Nazis began the systematic killing of Jews.
Thirty-three years after dropping out of college, Spielberg finally received a BA in Film and Video Production from his newly minted alma mater, Cal State Long Beach, in 2002. The director re-enrolled in secret, and gained his remaining credits by writing essays and submitting projects under a pseudonym. In order to pass a film course, he submitted Schindler’s List as his student project. Spielberg describes the time gap between leaving school and earning his degree as his “longest post-production schedule.”

Guderian had written a military pamphlet called “Achtung Panzer” which got into the hands of Hitler. As a tactic it was used to devastating effect in the first years of World War Two and resulted in the British and French armies being pushed back in just a few weeks to the beaches of Dunkirk. It was also pivotal in the German army’s devastation of Russian forces when they advanced through Russia in June 1941.

The word “Holocaust,” from the Greek words “holos” (whole) and “kaustos” (burned), was historically used to describe a sacrificial offering burned on an altar. Since 1945, the word has taken on a new and horrible meaning: the mass murder of some 6 million European Jews (as well as millions of others, including Gypsies and homosexuals) by the German Nazi regime during the Second World War. To the anti-Semitic Nazi leader Adolf Hitler, Jews were an inferior race, an alien threat to German racial purity and community. After years of Nazi rule in Germany, during which Jews were consistently persecuted, Hitler’s “final solution”–now known as the Holocaust–came to fruition under the cover of world war, with mass killing centers constructed in the concentration camps of occupied Poland.
Initially, Schindler was mostly interested in the money-making potential of the business and hired Jews because they were cheaper than Poles—the wages were set by the occupying Nazi regime.[38] Later he began shielding his workers without regard for cost.[39] The status of his factory as a business essential to the war effort became a decisive factor enabling him to help his Jewish workers. Whenever Schindlerjuden (Schindler Jews) were threatened with deportation, he claimed exemptions for them. He claimed wives, children, and even people with disabilities were necessary mechanics and metalworkers.[39] On one occasion, the Gestapo came to Schindler demanding that he hand over a family that possessed forged identity papers. "Three hours after they walked in," Schindler said, "two drunk Gestapo men reeled out of my office without their prisoners and without the incriminating documents they had demanded."[40]
