The Nazis considered Jews to be the main danger to Germany. Jews were the primary victims of Nazi racism, but other victims included Roma (Gypsies) and people with mental or physical disabilities. The Nazis murdered some 200,000 Roma. And they murdered at least 250,000 mentally or physically disabled patients, mainly German and living in institutions, in the so-called Euthanasia Program.
The Third Reich first used concentration camps as places of unlawful incarceration of political opponents and other "enemies of the state". Large numbers of Jews were not sent there until after Kristallnacht in November 1938.[182] Although death rates were high, the camps were not designed as killing centers.[183] After war broke out in 1939, new camps were established, some outside Germany in occupied Europe.[184] In January 1945, the SS reports had over 700,000 prisoners in their control, of which close to half had died by the end of May 1945 according to most historians.[185] Most wartime prisoners of the camps were not Germans but belonged to countries under German occupation.[186]
Killing on a mass scale using gas chambers or gas vans was the main difference between the extermination and concentration camps.[269] From the end of 1941, the Germans built six extermination camps in occupied Poland: Auschwitz II-Birkenau, Majdanek, Chełmno, and the three Operation Reinhard camps at Belzec, Sobibor, and Treblinka II.[44][270] Maly Trostenets, a concentration camp in the Reichskommissariat Ostland, became a killing centre in 1942.[44] Gerlach writes that over three million Jews were murdered in 1942, the year that "marked the peak" of the mass murder of Jews.[271] At least 1.4 million of these were in the General Government area of Poland.[272]
Although the prisoners deployed at Emalia were still subject to the brutal conditions of the Plaszow concentration camp, Schindler intervened repeatedly on their behalf. He used bribes and personal diplomacy both for the well-being of Jews threatened on an individual basis and to ensure, until late 1944, that the SS did not deport his Jewish workers. In order to claim the Jewish workers to be essential to the war effort, he added an armaments manufacturing division to Emalia. During the liquidation of the Krakow ghetto in March 1943, Schindler allowed his Jewish workers to stay at the factory overnight.

However, Schindler's financial woes continued, and he went bankrupt in 1958. He left his wife Emilie in Argentina to find fortune back in Germany, but despite his efforts, his various businesses repeatedly failed. Again, he had to depend on the charity of the Schindler Jews, many of whom he was still in contact with, to support his well being. In 1963, the same year he declared bankruptcy, he was honored by the State of Israel as Righteous Among the Nations, an award for non Jews who helped save Jews during the Holocaust. A year later, he had a heart attack and spent time recuperating in a hospital.
In less than 24 hours I shall be departing with my wife and two friends for a holiday in Krakow. As a minority of one I have been outvoted on whether we should visit Auschwitz Berkenau. Very reluctantly I will go. As an ex soldier, I am hardly a shrinking violet and perhaps more aware than some of the horrors of war or even lesser conflicts. I don't need to pore over such things. But many seem to cherish a ghoulish and prurient interest in such places. They are right to remember what happened there. From such knowledge mankind just might avoid or prevent anything similar happening again...but I doubt it. Look around the world. Horrors have existed, still exist and almost certainly will happen again. The scale is not the most significant factor. One child or adult butchered with machettes, bombs or bullets or bombs or tortured to death is just as horrific. Somehow I already feel guilty for allowing myself to go. For me it is almost on a par with digging up a coffin just to observe the putrefying remains of some departed soul. Why do some feel compelled to do that...does it awake in some a compassion that they did not previously have? No number of visits to such places can possibly make anyone feel and suffer as the inmates undoubtedly did. It takes some considerable effort to understand how a post-Auschwitz society can promote and run profiteering bus tours to one of the closest places humanity has to Hell. History cannot be changed by tears. Perhaps it is a forlorn hope but we would all do well to remember such places and events and then move forwards, using our best efforts to stop the slaughters that are occurring right now. That is where our consciences and efforts are most needed.

When he learned what had happened, Schindler at first managed to secure the release of the men from the Gross-Rosen camp.  He then proceeded to send his personal German secretary to Auschwitz to negotiate the release of the women. The latter managed to obtain the release of the Jewish women by promising to pay 7 RM daily per worker. This is the only recorded case in the history of the extermination camp that such a large group of people were allowed to leave alive while the gas chambers were still in operation.
Germany invaded Norway and Denmark on 9 April 1940, during Operation Weserübung. Denmark was overrun so quickly that there was no time for an organized resistance to form. Consequently, the Danish government stayed in power and the Germans found it easier to work through it. Because of this, few measures were taken against the Danish Jews before 1942.[157] By June 1940 Norway was completely occupied.[158] In late 1940, the country's 1,800 Jews were banned from certain occupations, and in 1941 all Jews had to register their property with the government.[159] On 26 November 1942, 532 Jews were taken by police officers, at four o'clock in the morning, to Oslo harbour, where they boarded a German ship. From Germany they were sent by freight train to Auschwitz. According to Dan Stone, only nine survived the war.[160]
The first mass transport to Auschwitz I, which included Catholic prisoners, suspected members of the Polish resistance, and 20 Jews, arrived on 14 June 1940 from prison in Tarnów, Poland. They were interned in the former building of the Polish Tobacco Monopoly, adjacent to the site, until the camp was ready.[24] By the end of 1940, the SS had confiscated land around the camp to create a 40-square-kilometre (15 sq mi) "zone of interest" surrounded by a double ring of electrified barbed wire fences and watchtowers.[25] The inmate population grew quickly as the camp absorbed Poland's intelligentsia and dissidents. By March 1941, 10,900 were imprisoned there, most of them Poles.[22]
The government defined a Jewish person as someone with three or four Jewish grandparents, not someone who had religious convictions. This meant that people who had never practiced, or hadn’t practiced Judaism in many years, or even converted to Christianity were subjected to persecution. Although anti-semitism was pervasive in 1930s Germany, these restrictions frequently extended to any person the Nazis considered to be “non-Aryan”.
Although effective in quick campaigns against Poland and France, blitzkrieg could not be sustained by Germany in later years. Blitzkrieg strategy has the inherent danger of the attacking force overextending its supply lines, and the strategy as a whole can be defeated by a determined foe who is willing to sacrifice territory for time in which to regroup and rearm, as the Soviets did on the Eastern Front. Tank and vehicle production was a constant problem for Germany; indeed, late in the war many panzer "divisions" had no more than a few dozen tanks. As the end of the war approached, Germany also experienced critical shortages in fuel and ammunition stocks as a result of Anglo-American strategic bombing. Although production of Luftwaffe fighter aircraft continued, they would be unable to fly for lack of fuel. What fuel there was went to panzer divisions, and even then they were not able to operate normally. Of those Tiger tanks lost against the United States Army, nearly half of them were abandoned for lack of fuel.
The word “Holocaust,” from the Greek words “holos” (whole) and “kaustos” (burned), was historically used to describe a sacrificial offering burned on an altar. Since 1945, the word has taken on a new and horrible meaning: the mass murder of some 6 million European Jews (as well as millions of others, including Gypsies and homosexuals) by the German Nazi regime during the Second World War. To the anti-Semitic Nazi leader Adolf Hitler, Jews were an inferior race, an alien threat to German racial purity and community. After years of Nazi rule in Germany, during which Jews were consistently persecuted, Hitler’s “final solution”–now known as the Holocaust–came to fruition under the cover of world war, with mass killing centers constructed in the concentration camps of occupied Poland.
^ In his testimony, according to Polish historian Aleksander Lasik, "Höss neither protected anyone nor evaded his own responsibility. His stance came as a surprise to many, especially those who viewed him as a bloodthirsty beast. Instead, he viewed his crimes in terms of the technical obstacles and challenges with which he had to cope. Höss stated that he led the killings in Auschwitz on express orders of Reichsführer Himmler."[264]
Blitzkrieg's immediate development began with Germany's defeat in the First World War. Shortly after the war, the new Reichswehr created committees of veteran officers to evaluate 57 issues of the war. The reports of these committees formed doctrinal and training publications which were the standards in the Second World War. The Reichswehr was influenced by its analysis of pre-war German military thought, in particular its infiltration tactics of the war, and the maneuver warfare which dominated the Eastern Front.
 In October 1944, after the SS transferred the Emalia Jews to Plaszow, Schindler sought and obtained authorization to relocate his plant to Brünnlitz (Brnenec) in Moravia, and reopen it exclusively as an armaments factory. One of his assistants drew several versions of a list of up to 1,200 Jewish prisoners needed to work in the new factory. These lists came to be known collectively as “Schindler's List.” Schindler met the specifications required by the SS to classify Brünnlitz as a subcamp of Gross-Rosen concentration camp and thereby facilitated the survival of around 800 Jewish men whom the SS deported from Plaszow via Gross-Rosen to Brünnlitz and between 300 and 400 Jewish women from Plaszow via Auschwitz.
Oskar Schindler (28 April 1908 – 9 October 1974) was a German industrialist and a member of the Nazi Party who is credited with saving the lives of 1,200 Jews during the Holocaust by employing them in his enamelware and ammunitions factories in occupied Poland and the Protectorate of Bohemia and Moravia. He is the subject of the 1982 novel Schindler's Ark and its 1993 film adaptation, Schindler's List, which reflected his life as an opportunist initially motivated by profit, who came to show extraordinary initiative, tenacity, courage, and dedication to save the lives of his Jewish employees.
