Using gas vans, Chełmno had its roots in the Aktion T4 euthanasia program. Majdanek began as a POW camp, but in August 1942 it had gas chambers installed. A few other camps are occasionally named as extermination camps, but there is no scholarly agreement on the additional camps; commonly mentioned are Mauthausen in Austria and Stutthof. There may also have been plans for camps at Mogilev and Lvov.
Schindler founded the first foreign subsidiary in Berlin (Germany) in 1906. Thereafter, the company expanded continuously and mainly throughout Europe. The company established a branch in London in 1960, operating under the name Platt-Schindler and in France after acquiring Roux Combaluzier in 1969, which it was later known as Roux Combaluzier Schindler or RCS. In the 1970s, Schindler moves to its current headquarter in Ebikon, Switzerland.
In 1933, Jews in Germany numbered around 525,000, or only 1 percent of the total German population. During the next six years, Nazis undertook an “Aryanization” of Germany, dismissing non-Aryans from civil service, liquidating Jewish-owned businesses and stripping Jewish lawyers and doctors of their clients. Under the Nuremberg Laws of 1935, anyone with three or four Jewish grandparents was considered a Jew, while those with two Jewish grandparents were designated Mischlinge (half-breeds).
On April 15, 1945, British troops entered Bergen Belsen. They liberated some 60,000 prisoners, many of whom were on the verge of death. During the first weeks after liberation, close to 500 people in Bergen Belsen died every day. From liberation day until June 20, an estimated 14,000 people died from the terrible conditions that had been inflicted on them by the Nazis during the war.
Victims usually arrived at the camps by freight train. Almost all arrivals at the Operation Reinhard camps of Treblinka, Sobibór, and Bełżec were sent directly to the gas chambers, with individuals occasionally selected to replace dead workers. At Auschwitz, camp officials usually subjected individuals to selections; about 25% of the new arrivals were selected to work. Those selected for death at all camps were told to undress and hand their valuables to camp workers. They were then herded naked into the gas chambers. To prevent panic, they were told the gas chambers were showers or delousing chambers. The procedure at Chełmno was slightly different. Victims there were placed in a mobile gas van and asphyxiated, while being driven to prepared burial pits in the nearby forests. There the corpses were unloaded and buried.
Anti-Jewish measures were introduced in Slovakia, which would later deport its Jews to German concentration and extermination camps. Bulgaria introduced anti-Jewish measures in 1940 and 1941, including the requirement to wear a yellow star, the banning of mixed marriages, and the loss of property. Bulgaria annexed Thrace and Macedonia, and in February 1943 agreed to deport 20,000 Jews to Treblinka; all 11,000 Jews from the annexed territories were sent to their deaths, and plans were made to deport an additional 6,000–8,000 Bulgarian Jews from Sofia to meet the quota. When the plans became public, the Orthodox Church and many Bulgarians protested, and King Boris III canceled the deportation of Jews native to Bulgaria. Instead, they were expelled to the interior pending further decision. Although Hungary expelled Jews who were not citizens from its newly annexed lands in 1941, it did not deport most of its Jews until the German invasion of Hungary in March 1944. Between 15 May and 9 July 1944, 440,000 Hungarian Jews were deported to Auschwitz. In late 1944 in Budapest, nearly 80,000 Jews were killed by the Hungarian Arrow Cross battalions.
When asked, Schindler told that his metamorphosis during the war was sparked by the shocking immensity of the Final Solution. In his own words: "I hated the brutality, the sadism, and the insanity of Nazism. I just couldn't stand by and see people destroyed. I did what I could, what I had to do, what my conscience told me I must do. That's all there is to it. Really, nothing more."
The workers who constructed the original buildings were housed in camps near Fallingbostel and Bergen, the latter being the so-called Bergen-Belsen Army Construction Camp. Once the military complex was completed in 1938/39, the workers' camp fell into disuse. However, after the German invasion of Poland in September 1939, the Wehrmacht began using the huts as a prisoner of war (POW) camp.
