Military historians have defined blitzkrieg as the employment of the concepts of maneuver and combined arms warfare developed in Germany during both the interwar period and the Second World War. Strategically, the ideal was to swiftly effect an adversary's collapse through a short campaign fought by a small, professional army. Operationally, its goal was to use indirect means, such as, mobility and shock, to render an adversary's plans irrelevant or impractical. To do this, self-propelled formations of tanks; motorized infantry, engineers, artillery; and ground-attack aircraft operated as a combined-arms team. Historians have termed it a period form of the longstanding German principle of Bewegungskrieg, or movement war.

Living standards were not high in the late 1930s. Consumption of consumer goods had fallen from 71 percent in 1928 to 59 percent in 1938. The demands of the war economy reduced the amount of spending in non-military sectors to satisfy the demand for the armed forces. On 9 September, Göring as Head of the Reich Defence Council, called for complete "employment" of living and fighting power of the national economy for the duration of the war. Overy presents this as evidence that a "blitzkrieg economy" did not exist.[133]
Meanwhile, beginning in the fall of 1939, Nazi officials selected around 70,000 Germans institutionalized for mental illness or disabilities to be gassed to death in the so-called Euthanasia Program. After prominent German religious leaders protested, Hitler put an end to the program in August 1941, though killings of the disabled continued in secrecy, and by 1945 some 275,000 people deemed handicapped from all over Europe had been killed. In hindsight, it seems clear that the Euthanasia Program functioned as a pilot for the Holocaust.
The Germans conquered large areas of the Soviet Union but their failure to destroy the Red Army before the winter of 1941 was a strategic failure that made German tactical superiority and territorial gains irrelevant.[95] The Red Army had survived enormous losses and regrouped with new formations far to the rear of the front line. During the Battle of Moscow, the Red Army defeated the German Army Group Center and for the first time in the war seized the strategic initiative.[95][96]
The town of Auschwitz was a major railroad hub, with many train tracks coming into it, and a large marshaling yard near the Auschwitz station. Standing on the railroad overpass in 1941, Himmler realized that Birkenau was an ideal location for transporting people by rail from all over Europe, although the plans for exterminating the Jews were not finalized until the Nazis were confident that they would win their war against the Soviet Union.

Several protective zones surround components of the World Heritage property and function de facto as buffer zones. They are covered by local spatial development plans, which are consulted by the Regional Monuments Inspector. The management of the property’s setting is the responsibility of the local government of the Town and Commune of Oświęcim. For better management and protection of the attributes of the Outstanding Universal Value of the property, especially for the proper protection of its setting, a relevant management plan must be put into force.

Schindler joined the separatist Sudeten German Party in 1935.[6] Although he was a citizen of Czechoslovakia, Schindler became a spy for the Abwehr, the military intelligence service of Nazi Germany, in 1936. He was assigned to Abwehrstelle II Commando VIII, based in Breslau.[7] He later told Czech police that he did it because he needed the money; by this time Schindler had a drinking problem and was chronically in debt.[8]
