In 1935 Schindler joined the pro-Nazi Sudeten German Party (Sudetendeutsche Partei; SdP) and the next year began collecting counterintelligence for the Abwehr, the German military intelligence agency. In 1938 he was arrested by Czechoslovak authorities on charges of espionage and sentenced to death. After the annexation of the Sudetenland by Germany late that year as part of the Munich Agreement, Schindler was pardoned by the Reich and rose through the ranks of the Abwehr. His application for membership in the Nazi Party—thought to have been submitted out of pragmatism rather than ideological affinity—was accepted in 1939. That year, on the heels of the German invasion and occupation of Poland, Schindler journeyed to Kraków, where he became active in the emerging black market. Thanks to the network of German contacts he had arranged through liberal bribes, he secured the lease of a formerly Jewish-owned enamelware factory. He renamed the facility Deutsche Emaillewaren-Fabrik Oskar Schindler (known as Emalia) and commenced production with a small staff. Three months later he had several hundred employees, seven of whom were Jewish. By 1942 nearly half of the workers at the expanded plant were Jewish. (Ostensibly “cheap labour,” Schindler paid their salaries to the SS.)
Although she struggled with resentment towards her late husband for his womanizing and marital neglect, Emilie still had profound love for Schindler. Revealing her internal dialogue when she visited his tomb almost 40 years after his passing, she had said to him: "At last we meet again . . .I have received no answer, my dear, I do not know why you abandoned me . . . But what not even your death or my old age can change is that we are still married, this is how we are before God. I have forgiven you everything, everything. . ."
The Germans invaded the Netherlands, Luxembourg, Belgium, and France in May 1940. In the Netherlands, the Germans installed Arthur Seyss-Inquart as Reichskommissar, who quickly began to persecute the approximately 140,000 Dutch Jews. Jews were forced out of their jobs and had to register with the government. Non-Jewish Dutch citizens protested these measures, and in February 1941 they staged a strike that was quickly crushed.[161] After Belgium's surrender at the end of May 1940, it was ruled by a German military governor, Alexander von Falkenhausen, who enacted anti-Jewish measures against the country's 90,000 Jews, many of whom were refugees from Germany or Eastern Europe.[162]
On May 19th, 1939, the S.S. St. Louis sailed from Hamburg, Germany to Havana, Cuba with 937 passengers; almost all of them were Jews escaping with their lives. This was one of the last ships that left Germany before the outbreak of World War II. Most of the passengers had applied for U.S. visas and were only planning on staying in Cuba until they could enter into the United States. The U.S. State Department in Washington, the U.S. consulate in Havana, and the owner of the St. Louis were aware that they might not be able to enter Cuba, but the passengers were never told.

Italy introduced some antisemitic measures, but there was less antisemitism there than in Germany, and Italian-occupied countries were generally safer for Jews than German-occupied territories. In some areas, the Italian authorities even tried to protect Jews, such as in the Croatian areas of the Balkans. But while Italian forces in Russia were not as vicious towards Jews as the Germans, they did not try to stop German atrocities either. There were no deportations of Italian Jews to Germany while Italy remained an ally.[171] Several forced labor camps for Jews were established in Italian-controlled Libya. Almost 2,600 Libyan Jews were sent to camps, where 562 died.[172]
German operational theories were revised after the First World War. The Treaty of Versailles limited the Reichswehr to a maximum of 100,000 men, making impossible the deployment of mass armies. The German General Staff was abolished by the treaty but continued covertly as the Truppenamt (Troop Office), disguised as an administrative body. Committees of veteran staff officers were formed within the Truppenamt to evaluate 57 issues of the war.[29] By the time of the Second World War, their reports had led to doctrinal and training publications, including H. Dv. 487, Führung und Gefecht der verbundenen Waffen (Command and Battle of the Combined Arms), known as das Fug (1921–23) and Truppenführung (1933–34), containing standard procedures for combined-arms warfare. The Reichswehr was influenced by its analysis of pre-war German military thought, in particular infiltration tactics, which at the end of the war had seen some breakthroughs on the Western Front and the manoeuvre warfare which dominated the Eastern Front.

The Auschwitz Birkenau camp complex comprises 155 brick and wooden structures (57 in Auschwitz and 98 in Birkenau) and about 300 ruins. There are also ruins of gas chambers and crematoria in Birkenau, which were dynamited in January 1945. The overall length of fencing supported by concrete poles is more than 13 km. Individual structures of high historical significance, such as railway sidings and ramps, food stores and industrial buildings, are dispersed in the immediate setting of the property. These structures, along with traces in the landscape, remain poignant testimonies to this tragic history.

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.

By January 1945 Soviet troops were advancing towards Auschwitz. In desperation to withdraw, the Nazis sent most of the 58,000 remaining prisoners on a death march to Germany, and most prisoners were killed en route. When the Soviet army liberated Auschwitz on January 27, soldiers found only 7,650 barely living prisoners throughout the entire camp complex. In all, approximately one million Jews had been murdered there.

On 2 July 1947, the Polish government passed a law establishing a state memorial to remember "the martyrdom of the Polish nation and other nations in Oswiecim".[284] The museum established its exhibits at Auschwitz I; after the war, the barracks in Auschwitz II-Birkenau had been mostly dismantled and moved to Warsaw to be used on building sites. Dwork and van Pelt write that, in addition, Auschwitz I played a more central role in the persecution of the Polish people, in opposition to the importance of Auschwitz II to the Jews, including Polish Jews.[285] An exhibition opened in Auschwitz I in 1955, displaying prisoner mug shots; hair, suitcases, and shoes taken from murdered prisoners; canisters of Zyklon B pellets; and other objects related to the killings.[286] UNESCO added the camp to its list of World Heritage Sites in 1979.[287] All the museum's directors were, until 1990, former Auschwitz prisoners. Visitors to the site have increased from 492,500 in 2001, to over one million in 2009,[288] to two million in 2016.[289]
Aware that as witnesses to the killings they would eventually be killed themselves, the Sonderkommandos of Birkenau Kommando III staged an uprising on 7 October 1944, following an announcement that some of them would be selected to be "transferred to another camp"—a common Nazi ruse for the murder of prisoners.[228][229] They attacked the SS guards with stones, axes, and makeshift hand grenades, which they also used to damage Crematorium IV and set it on fire. As the SS set up machine guns to attack the prisoners in Crematorium IV, the Sonderkommandos in Crematorium II also revolted, some of them managing to escape the compound.[229][230] The rebellion was suppressed by nightfall.[231]
The Holocaust was the systematic, bureaucratic, state-sponsored persecution and murder of six million Jews by the Nazi regime and its collaborators. Holocaust is a word of Greek origin meaning "sacrifice by fire." The Nazis, who came to power in Germany in January 1933, believed that Germans were "racially superior" and that the Jews, deemed "inferior," were an alien threat to the so-called German racial community.
The SchindlerMobile is a self-propelled car has wheels to move itself up and down self-supporting aluminum columns. It doesn't have a machine room, no suspension ropes, and no hoistway walls. It was introduced in 1997, but later discontinued and replaced with the Schindler EuroLift elevators in 2001. SchindlerMobile was produced in its factory in Schlatt, Switzerland.
Because they refused to pledge allegiance to the Nazi party or serve in the military, Jehovah's Witnesses were sent to concentration camps, where they were identified by purple triangles and given the option of renouncing their faith and submitting to the state's authority.[447] The United States Holocaust Memorial Museum estimates that between 2,700 and 3,300 were sent to the camps, where 1,400 died;[411] in The Holocaust Encyclopedia (2001), Sybil Milton estimates that 10,000 were sent and 2,500 died.[412] According to German historian Detlef Garbe, "no other religious movement resisted the pressure to conform to National Socialism with comparable unanimity and steadfastness."[448]

An inmate's first encounter with the camp, if they were being registered and not sent straight to the gas chamber, would be at the prisoner reception centre, where they were tattooed, shaved, disinfected, and given their striped prison uniform. Built between 1942 and 1944, the center contained a bathhouse, laundry, and 19 gas chambers for delousing clothes. Debórah Dwork and Robert Jan van Pelt write that inmates would then leave this area via a porch that faced the gate with the Arbeit macht frei sign. The prisoner reception center of Auschwitz I became the visitor reception center of the Auschwitz-Birkenau Memorial and Museum.[20]

Conventional wisdom traces blitzkrieg, “lightning war,” to the development in Germany between 1918 and 1939 of a body of doctrine using mobility to prevent repetition of the attritional deadlock of World War I. Soldiers such as Hans von Seeckt and Heinz Guderian allegedly perceived more clearly than their counterparts elsewhere in Europe the military potential of the internal-combustion engine combined with modern communications technology. Large formations moving on tracks and wheels, directed by radios, could rupture an enemy’s front and so disorganize its rear that countermeasures would be paralyzed. First tested in Poland, the concept reached perihelion in France and the Low Countries in 1940, when in less than six weeks the German army crushed the combined forces of four nations. Applied a year later against the Soviet Union, blitzkrieg purportedly brought the Wehrmacht to the gates of Moscow in six months. Some accounts insist that only Adolf Hitler’s incompetent interference tipped the war’s balance so far against Germany that even blitzkrieg’s most sophisticated refinements could do no more than stave off the Reich’s collapse.
After becoming Chancellor of Germany (head of government) in 1933, Adolf Hitler ignored the Versailles Treaty provisions. Within the Wehrmacht (established in 1935) the command for motorised armored forces was named the Panzerwaffe in 1936. The Luftwaffe (the German air force) was officially established in February 1935, and development began on ground-attack aircraft and doctrines. Hitler strongly supported this new strategy. He read Guderian's 1937 book Achtung – Panzer! and upon observing armoured field exercises at Kummersdorf he remarked, "That is what I want – and that is what I will have."[51][52]

On June 6, 1944, also known as D-Day, more than 150,000 Allied soldiers landed in France. In December the Germans started an unsuccessful counterattack in Belgium and northern France, known as the Battle of the Bulge. Continuing to gain momentum, the Soviets began an offensive in January 1945, liberating western Poland and then forcing Hungary to surrender.
The concept of blitzkrieg was formed by Prussian military tactics of the early 19th century, which recognized that victory could come only through forceful and swift action because of Prussia’s relatively limited economic resources. It had its origins with the Schwerpunktprinzip (“concentration principle”) proposed by Carl von Clausewitz in his seminal work On War (1832). Having studied generals who predated Napoleon, Clausewitz found that commanders of various armies had dispersed their forces without focused reasoning, which resulted in those forces’ being used inefficiently. So as to eliminate that wasteful use of manpower, he advocated for a concentration of force against an enemy. All employment of force should have an effective concentration in a single moment, with a single action, Clausewitz argued. Clausewitz called that concentration the Schwerpunkt (“centre of gravity”) where it was most dense, identifying it as the effective target for attack.
The brick barracks were constructed in the autumn of 1941. The Germans originally intended the barracks to house 40 prisoners, but very often more than 700 would be placed in each of them. The total number of prisoners to each barrack depended on the number of transports arriving. The prisoners slept in 60 spaces, with three bunks in each space. Prisoners slept on straw spread over the wooden bunks. The barracks had earth floors and few sanitary facilities.

The majority—probably about 90%—of the victims of Auschwitz Concentration Camp died in Birkenau. This means approximately a million people. The majority, more than nine out of every ten, were Jews. A large proportion of the more than 70 thousand Poles who died or were killed in the Auschwitz complex perished in Birkenau. So did approximately 20 thousand Gypsies, in addition to Soviet POWs and prisoners of other nationalities. 
^ Some of the military historians who consider Operation Citadel, or at least the southern pincer, as envisioning a blitzkrieg attack or state it was intended as such are: Lloyd Clark (Clark 2012, p. 187), Roger Moorhouse (Moorhouse 2011, p. 342), Mary Kathryn Barbier (Barbier 2002, p. 10), David Glantz (; Glantz & House 2004, pp. 63, 78, 149, 269, 272, 280), Jonathan House (Glantz & House 2004, pp. 63, 78, 149, 269, 272, 280), Hedley Paul Willmott (Willmott 1990, p. 300), Oscar Pinkus (Pinkus 2005, p. 35) and others.

Auschwitz II, located in the village of Birkenau, or Brzezinka, just outside OÅ›wiÄ™cim, was constructed in 1941 on the order of Heinrich Himmler (1900-45), commander of the “Schutzstaffel” (or Select Guard/Protection Squad, more commonly known as the SS), which operated all Nazi concentration camps and death camps. Birkenau, the biggest of the Auschwitz facilities, could hold some 90,000 prisoners. It also housed a group of bathhouses where countless people were gassed to death, and crematory ovens where bodies were burned. The majority of Auschwitz victims died at Birkenau.More than 40 smaller facilities, called subcamps, dotted the landscape and served as slave-labor camps. The largest of these subcamps, Monowitz, also known as Auschwitz III, began operating in 1942 and housed some 10,000 prisoners.
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.[18][19] 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.[20]
