In the decades since its liberation, Auschwitz has become a primary symbol of the Holocaust. Historian Timothy D. Snyder attributes this to the camp's high death toll and "unusual combination of an industrial camp complex and a killing facility", which left behind far more witnesses than single-purpose killing facilities such as Chełmno or Treblinka.[271] In 2005 the United Nations General Assembly designated 27 January, the date of the camp's liberation, as International Holocaust Remembrance Day.[272] Helmut Schmidt visited the site in November 1977, the first West German chancellor to do so, followed by his successor, Helmut Kohl, in November 1989.[273] In a written statement on the fiftieth anniversary of the liberation, Kohl described Auschwitz as the "darkest and most horrific chapter of German history".[274]

These techniques were used to great effect in 1939, when the Polish Army was destroyed in a series of encirclement battles. In May 1940 Hitler attacked France, his panzer divisions smashing through slow-moving French formations and cutting off the British Expeditionary Force at Dunkirk. Spectacular success was also achieved during the invasion of the Soviet Union in 1941 and large numbers of Soviet troops were captured.
The resistance sent out the first oral message about Auschwitz with Dr. Aleksander Wielkopolski, a Polish engineer who was released in October 1940.[201] The following month the Polish underground in Warsaw prepared a report on the basis of that information, The camp in Auschwitz, part of which was published in London in May 1941 in a booklet, The German Occupation of Poland, by the Polish Ministry of Foreign Affairs. The report said of the Jews in the camp that "scarcely any of them came out alive". According to Fleming, the booklet was "widely circulated amongst British officials". The Polish Fortnightly Review based a story on it, writing that "three crematorium furnaces were insufficient to cope with the bodies being cremated", as did The Scotsman on 8 January 1942, the only British news organization to do so.[202]
^ Jump up to: a b Dan Stone (Histories of the Holocaust, 2010): "Europe's Romany (Gypsy) population was also the victim of genocide under the Nazis. Many other population groups, notably Poles, Ukrainians, and Soviet prisoners of war were killed in huge numbers, and smaller groups such as Jehovah's Witnesses, Black Germans, and homosexuals suffered terribly under Nazi rule. The evidence suggests that the Slav nations of Europe were also destined, had Germany won the war, to become victims of systematic mass murder; and even the terrible brutality of the occupation in eastern Europe, especially in Poland, can be understood as genocidal according to the definition put forward by Raphael Lemkin in his major study, Axis Rule in Occupied Europe (1944), the book that introduced the term 'genocide' to our vocabulary. Part of the reason for today's understanding, though, is a correct assessment of the fact that for the Nazis the Jews were regarded in a kind of 'metaphysical' way; they were not just considered as racially inferior (like Romanies), deviants (like homosexuals) or enemy nationals standing in the way of German colonial expression (like Slavs). ... [T]he Jews were to some extent outside of the racial scheme as defined by racial philosophers and anthropologists. They were not mere Untermenschen (sub-humans) ... but were regarded as a Gegenrasse: "a 'counter-race', that is to say, not really human at all. ... 'Holocaust', then, refers to the genocide of the Jews, which by no means excludes an understanding that other groups—notably Romanies and Slavs—were victims of genocide. Indeed ... the murder of the Jews, although a project in its own right, cannot be properly historically situated without understanding the 'Nazi empire' with its grandiose demographic plans."[32]
On 15 September 1935, the Reichstag passed the Nuremberg Laws, prohibiting marriages between Jews and people of Germanic extraction, extramarital relations between Jews and Germans, and the employment of German women under the age of 45 as domestic servants in Jewish households.[12] The Reich Citizenship Law defined as citizens those of "German or kindred blood". Thus Jews and other minorities were stripped of their citizenship.[13] By the start of World War II in 1939, around 250,000 of Germany's 437,000 Jews had emigrated to the United States, Palestine, the United Kingdom, and other countries.[14][15]

He began by turning his factory into an official subcamp of a newly constructed labor camp at Plazów. For a time, it was a haven for about 500 Jews. Then, in the fall of 1944, the Nazis ordered both camps closed and all workers shipped to Auschwitz, a killing center. Schindler refused to let that happen. He put together a list of 1,100 men, women, and children that he claimed as his workers. He then used his money and influence to transport those workers to a new factory he was building at Brinnlitz, Czechoslovakia. When the Jewish women who worked in his factory were transported to Auschwitz by mistake, he accomplished the impossible: he managed to get the women back by offering Nazi officials a fortune in bribes.
Remarkably, there were instances of individual resistance and collective efforts at fighting back inside Auschwitz. Poles, Communists and other national groups established networks in the main camp. Some Jews assaulted Nazi guards, even at the entrance to the gas chambers. In October 1944, the Sonderkommando crew at crematoria IV revolted and destroyed the crematoria. It was never used again.
SS officers, including the infamous Dr. Josef Mengele, would conduct selections among these lines, sending most victims to one side and thus condemning them to death in the gas chambers. A minority was sent to the other side, destined for forced labor. Those who were sent to their deaths were killed that same day and their corpses were burnt in the crematoria. Those not sent to the gas chambers were taken to “quarantine,” where their hair was shaved, striped prison uniforms distributed, and registration took place. Prisoners’ individual registration numbers were tattooed onto their left arm.

What the arms, whose charges can be partly traced in tithing seals and boundary stones back to the 16th century, mean is unclear. The charge that the German blazon describes as a “wall anchor” (Maueranker) is not accepted as such by everyone, with some saying it could have been meant to be taken as a weaver’s reel. With a document from 22 July 1926, the interior minister of the People's State of Hesse granted the community the right to bear these arms.
Some Auschwitz prisoners were subjected to inhumane medical experimentation. The chief perpetrator of this barbaric research was Josef Mengele (1911-79), a German physician who began working at Auschwitz in 1943. Mengele, who came to be known as the “Angel of Death,” performed a range of experiments on detainees. For example, in an effort to study eye color, he injected serum into the eyeballs of dozens of children, causing them excruciating pain. He also injected chloroform into the hearts of twins, to determine if both siblings would die at the same time and in the same manner.

The Germans' overwhelming repression and the presence of many collaborators in the various local populations severely limited the ability of the Jews to resist. Jewish resistance did occur, however, in several forms. Staying alive, clean, and observing Jewish religious traditions constituted resistance under the dehumanizing conditions imposed by the Nazis. Other forms of resistance involved escape attempts from the ghettos and camps. Many who succeeded in escaping the ghettos lived in the forests and mountains in family camps and in fighting partisan units. Once free, though, the Jews had to contend with local residents and partisan groups who were often openly hostile. Jews also staged armed revolts in the ghettos of Vilna, Bialystok, Bedzin-Sosnowiec, krakow, and Warsaw.

Shortly after the outbreak of war in September 1939, thirty-one-year-old Schindler showed up in occupied Krakow. The ancient city, home to some 60,000 Jews and seat of the German occupation administration, the Generalgouvernement, proved highly attractive to German entrepreneurs, hoping to capitalize on the misfortunes of the subjugated country and make a fortune. Naturally cunning and none too scrupulous, Schindler appeared at first to thrive in these surroundings.  In October 1939, he took over a run-down enamelware factory that had previously belonged to a Jew.  He cleverly maneuvered his steps- acting upon the shrewd commercial advice of a Polish-Jewish accountant, Isaak Stern - and began to build himself a fortune. The small concern in Zablocie outside Krakow, which started producing kitchenware for the German army, began to grow by leaps and bounds. After only three months it already had a task-force of some 250 Polish workers, among them seven Jews. By the end of 1942, it had expanded into a mammoth enamel and ammunitions production plant, occupying some 45,000 square meters and employing almost 800 men and women. Of these, 370 were Jews from the Krakow ghetto, which the Germans had established after they entered the city.
The wooden barracks had once been stables. The walls were thin and had gaps at the bottom and top, which let in the bitterly cold wind in the winter. Near the entrance door were two rooms to house the ‘functionaries’ or kapos. The barracks had no windows, but instead had a row of skylights at the top of the roof. Each block had wooden three-tiered bunks. Prisoners slept under thin blankets or rags on their straw mattresses.
In 1940, Britain and France still had a World War One mentality. What tanks they had were poor compared to the German Panzers. British and French tactics were outdated and Britain still had the mentality that as an island they were safe as our navy would protect us. Nazi Germany, if it was to fulfill Hitler’s wishes, had to have a modern military tactic if it was to conquer Europe and give to Germany the ‘living space’ that Hitler deemed was necessary for the Third Reich. 
Around 50,000 German gay men were jailed between 1933 and 1945, and 5,000–15,000 are estimated to have been sent to concentration camps. It is not known how many died during the Holocaust.[413][449] James Steakley writes that what mattered in Germany was criminal intent or character, rather than acts, and the "gesundes Volksempfinden" ("healthy sensibility of the people") became the guiding legal principle.[450] In 1936, Himmler created the Reich Central Office for the Combating of Homosexuality and Abortion.[451] The Gestapo raided gay bars, tracked individuals using the address books of those they arrested, used the subscription lists of gay magazines to find others, and encouraged people to report suspected homosexual behavior and to scrutinize the behavior of their neighbors.[450] Lesbians were left relatively unaffected;[413] the Nazis saw them as "asocials", rather than sexual deviants.[452] Gay men convicted between 1933 and 1944 were sent to camps for "rehabilitation", where they were identified by pink triangles.[450] Hundreds were castrated, sometimes "voluntarily" to avoid criminal sentences.[453] Steakley writes that the full extent of gay suffering was slow to emerge after the war. Many victims kept their stories to themselves because homosexuality remained criminalized in postwar Germany.[450]
Although the term "concentration camps" is often used to describe all Nazi camps, there were actually a number of different kinds of camps, including transit camps, forced-labor camps, and death camps. In some of these camps there was at least a small chance to survive; while in others, there was no chance at all. When and where were these camps built? How many people were murdered in each one?
Several SS personnel oversaw the killings at each gas chamber, while the bulk of the work was done by the mostly Jewish prisoners known as Sonderkommandos (special squads).[91][92] Hungarian doctor Miklós Nyiszli reported that the Sonderkommando numbered around 860 prisoners when the Hungarian Jews were being killed in May–July 1944.[93] Their responsibilities included removing goods and corpses from the incoming trains, guiding victims to the dressing rooms and gas chambers, and working in the "Canada" barracks, where the victims' possessions were stored.[94] Housed separately from other prisoners, in somewhat better conditions, their quality of life was further improved by access to the goods taken from murdered prisoners, which they were sometimes able to steal and trade on Auschwitz's black market.[95] Many Sonderkommandos committed suicide in response to the horrors of their work; others were generally shot by the SS in a matter of weeks. New Sonderkommando units were formed from incoming transports. Almost none of the 2,000 prisoners placed in these units survived to the camp's liberation.[96]

After Germany’s loss in WWI, the Treaty of Versailles punished Germany by placing tough restrictions on the country. The treaty made Germany take full responsibility for the war, reduced the extent of German territory, severely limited the size and placement of their armed forces, and forced Germany to pay the allied powers reparations. These restrictions not only increased social unrest but, combined with the start of the Great Depression, collapsed the German economy as inflation rose alongside unemployment.
Initially Göth's plan was that all the factories, including Schindler's, should be moved inside the camp gates.[52] However, Schindler, with a combination of diplomacy, flattery, and bribery, not only prevented his factory from being moved, but convinced Göth to allow him to build (at Schindler's own expense) a subcamp at Emalia to house his workers plus 450 Jews from other nearby factories. There they were safe from the threat of random execution, were well fed and housed, and were permitted to undertake religious observances.[53][54]
