After Germany invaded Poland in September 1939, sparking World War II, the Germans converted Auschwitz I from an army barracks to hold Polish political prisoners. The first prisoners, German criminals brought to the camp as functionaries, arrived in May 1940, and the first gassing of prisoners took place in block 11 of Auschwitz I in September 1941. Auschwitz II–Birkenau went on to become a major site of the Nazis' Final Solution to the Jewish Question. From early 1942 until late 1944, transport trains delivered Jews from all over German-occupied Europe to the camp's gas chambers. Of the estimated 1.3 million people sent to Auschwitz, at least 1.1 million died, around 90 percent of them Jews. Approximately one in six Jews killed in the Holocaust died at the camp. Others deported to Auschwitz included 150,000 non-Jewish Poles, 23,000 Roma, 15,000 Soviet prisoners of war, 400 Jehovah's Witnesses, tens of thousands of others of diverse nationalities, and an unknown number of gay men. Many of those not killed in the gas chambers died because of starvation, forced labor, infectious diseases, individual executions, and medical experiments.
You can visit the site on your own (highly recommended because you can go at your own pace, see what you want to see and have a much more meaningful experience) if you arrive before the guided tours start. Another option is to visit the Auschwitz II-Birkenau site first and then return after the guided tours finish to the first camp to avoid having to use the tour. The Auschwitz II-Birkenau site is open for visitors without the guide during the opening hours of the Memorial.
Several SS personnel oversaw the killings at each gas chamber, while the bulk of the work was done by the mostly Jewish prisoners known as Sonderkommandos (special squads). Hungarian doctor Miklós Nyiszli reported that the Sonderkommando numbered around 860 prisoners when the Hungarian Jews were being killed in May–July 1944. Their responsibilities included removing goods and corpses from the incoming trains, guiding victims to the dressing rooms and gas chambers, and working in the "Canada" barracks, where the victims' possessions were stored. Housed separately from other prisoners, in somewhat better conditions, their quality of life was further improved by access to the goods taken from murdered prisoners, which they were sometimes able to steal and trade on Auschwitz's black market. Many Sonderkommandos committed suicide in response to the horrors of their work; others were generally shot by the SS in a matter of weeks. New Sonderkommando units were formed from incoming transports. Almost none of the 2,000 prisoners placed in these units survived to the camp's liberation.
In July 1938, representatives of 32 countries met in the French town of Evian to discuss the refugee and immigration problems created by the Nazis in Germany. Nothing substantial was done or decided at the Evian Conference, and it became apparent to Hitler that no one wanted the Jews and that he would not meet resistance in instituting his Jewish policies. By the autumn of 1941, Europe was in effect sealed to most legal emigration. The Jews were trapped.
As the Red Army drew nearer in July 1944, the SS began closing down the easternmost concentration camps and evacuating the remaining prisoners westward to Auschwitz and Gross-Rosen concentration camp. Göth's personal secretary, Mietek Pemper, alerted Schindler to the Nazis' plans to close all factories not directly involved in the war effort, including Schindler's enamelware facility. Pemper suggested to Schindler that production should be switched from cookware to anti-tank grenades in an effort to save the lives of the Jewish workers. Using bribery and his powers of persuasion, Schindler convinced Göth and the officials in Berlin to allow him to move his factory and his workers to Brünnlitz (Czech: Brněnec), in the Sudetenland, thus sparing them from certain death in the gas chambers. Using names provided by Jewish Ghetto Police officer Marcel Goldberg, Pemper compiled and typed the list of 1,200 Jews—1,000 of Schindler's workers and 200 inmates from Julius Madritsch's textiles factory—who were sent to Brünnlitz in October 1944.
James Corum wrote that it was a myth that the Luftwaffe had a doctrine of terror bombing, in which civilians were attacked to break the will or aid the collapse of an enemy, by the Luftwaffe in Blitzkrieg operations. After the bombing of Guernica in 1937 and the Rotterdam Blitz in 1940, it was commonly assumed that terror bombing was a part of Luftwaffe doctrine. During the interwar period the Luftwaffe leadership rejected the concept of terror bombing in favour of battlefield support and interdiction operations.
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.
In order to gain a more personal perspective on the film, Spielberg traveled to Poland before principal photography began to interview Holocaust survivors and visit the real-life locations that he planned to portray in the movie. While there, he visited the former Gestapo headquarters on Pomorska Street, Schindler’s actual apartment, and Amon Goeth’s villa.
Schindler first arrived in Kraków in October 1939, on Abwehr business, and took an apartment the following month. Emilie maintained the apartment in Ostrava and visited Oskar in Kraków at least once a week. In November 1939, he contacted interior decorator Mila Pfefferberg to decorate his new apartment. Her son, Leopold "Poldek" Pfefferberg, soon became one of his contacts for black market trading. They eventually became lifelong friends.
