When the women arrived to the factory in Brunnlitz, weak, hungry, frostbitten, less than human, Oskar Schindler met them in the courtyard. They never forgot the sight of Schindler standing in the doorway. And they never forgot his raspy voice when he - surrounded by SS guards - gave them an unforgettable guarantee: 'Now you are finally with me, you are safe now. Don't be afraid of anything. You don't have to worry anymore.'
As Soviet troops approached Auschwitz in January 1945, most of its population was sent west on a death march. The remaining prisoners were liberated on 27 January 1945, a day commemorated as International Holocaust Remembrance Day. In the following decades, survivors such as Primo Levi, Viktor Frankl, and Elie Wiesel wrote memoirs of their experiences in Auschwitz, and the camp became a dominant symbol of the Holocaust. In 1947 Poland founded the Auschwitz-Birkenau Memorial and Museum on the site of Auschwitz I and II, and in 1979 it was named a World Heritage Site by UNESCO.
The Nazi regime dominated neighbours through military threats in the years leading up to war. Nazi Germany made increasingly aggressive territorial demands, threatening war if these were not met. It seized Austria and Czechoslovakia in 1938 and 1939. Hitler made a non-aggression pact with Joseph Stalin and invaded Poland in September 1939, launching World War II in Europe. By early 1941, Germany controlled much of Europe. Reichskommissariats took control of conquered areas and a German administration was established in the remainder of Poland. Germany exploited the raw materials and labour of both its occupied territories and its allies. In the Holocaust, millions of Jews and other peoples deemed undesirable by the state were imprisoned, murdered in Nazi concentration camps and extermination camps, or shot.
To protect the supposed purity and strength of the Aryan race, the Nazis sought to exterminate Jews, Romani, Poles and most other Slavs, along with the physically and mentally handicapped. They disenfranchised and segregated homosexuals, Africans, Jehovah's Witnesses and political opponents. The persecution reached its climax when the party-controlled German state set in motion the Final Solution–an industrial system of genocide which achieved the murder of an estimated 5.5 to 6 million Jews and millions of other targeted victims, in what has become known as the Holocaust.
When three refugee physicists confided to Einstein that the Nazis might be developing a new weapon—an atomic bomb—he decided to act. Despite his previous appeals for governments to dispense with the weapons of war, Einstein wrote to President Franklin Roosevelt in 1939 alerting him to "a new phenomenon that would...lead to the construction of bombs" and suggested that the United States accelerate its atomic weapons research program. Scholars debate the effect of this letter. Einstein signed it in 1939 and the Manhattan Project, the U.S. effort to build the bomb, began in 1941.
Auschwitz, Polish Oświęcim, also called Auschwitz-Birkenau, Nazi Germany’s largest concentration camp and extermination camp. Located near the industrial town of Oświęcim in southern Poland (in a portion of the country that was annexed by Germany at the beginning of World War II), Auschwitz was actually three camps in one: a prison camp, an extermination camp, and a slave-labour camp. As the most lethal of the Nazi extermination camps, Auschwitz has become the emblematic site of the “final solution,” a virtual synonym for the Holocaust. Between 1.1 and 1.5 million people died at Auschwitz; 90 percent of them were Jews. Also among the dead were some 19,000 Roma who were held at the camp until the Nazis gassed them on July 31, 1944—the only other victim group gassed in family units alongside the Jews. The Poles constituted the second largest victim group at Auschwitz, where some 83,000 were killed or died.
The Nazis were initially very hostile to Catholics because most Catholics supported the German Centre Party. Catholics opposed the Nazis' promotion of compulsory sterilization of those whom they deemed inferior and the Catholic Church forbade its members to vote for the Nazis. In 1933, extensive Nazi violence occurred against Catholics due to their association with the Centre Party and their opposition to the Nazi regime's sterilization laws. The Nazis demanded that Catholics declare their loyalty to the German state. In their propaganda, the Nazis used elements of Germany's Catholic history, in particular the German Catholic Teutonic Knights and their campaigns in Eastern Europe. The Nazis identified them as "sentinels" in the East against "Slavic chaos", though beyond that symbolism, the influence of the Teutonic Knights on Nazism was limited. Hitler also admitted that the Nazis' night rallies were inspired by the Catholic rituals which he had witnessed during his Catholic upbringing. The Nazis did seek official reconciliation with the Catholic Church and they endorsed the creation of the pro-Nazi Catholic Kreuz und Adler, an organization which advocated a form of national Catholicism that would reconcile the Catholic Church's beliefs with Nazism. On 20 July 1933, a concordat (Reichskonkordat) was signed between Nazi Germany and the Catholic Church, which in exchange for acceptance of the Catholic Church in Germany required German Catholics to be loyal to the German state. The Catholic Church then ended its ban on members supporting the Nazi Party.
Successive Reichsstatthalter decrees between 1933 and 1935 abolished the existing Länder (constituent states) of Germany and replaced them with new administrative divisions, the Gaue, governed by NSDAP leaders (Gauleiters). The change was never fully implemented, as the Länder were still used as administrative divisions for some government departments such as education. This led to a bureaucratic tangle of overlapping jurisdictions and responsibilities typical of the administrative style of the Nazi regime.
As a result of the Holocaust, the term "concentration camp" carries many of the connotations of "extermination camp" and is sometimes used synonymously. Because of these ominous connotations, the term "concentration camp", originally itself a euphemism, has been replaced by newer terms such as internment camp, resettlement camp, detention facility, etc., regardless of the actual circumstances of the camp, which can vary a great deal.
