After invading Poland, the Germans established ghettos in the incorporated territories and General Government to confine Jews.[143] The ghettos were formed and closed off from the outside world at different times and for different reasons.[196][197] For example, the Łódź ghetto was closed in April 1940,[143] to force the Jews inside to give up money and valuables;[198] the Warsaw ghetto was closed for health considerations (for the people outside, not inside, the ghetto),[199] but this did not happen until November 1940;[143] and the Kraków ghetto was not established until March 1941.[200] The Warsaw Ghetto contained 380,000 people[143] and was the largest ghetto in Poland; the Łódź Ghetto was the second largest,[201] holding between 160,000[202] to 223,000.[203] Because of the long drawn-out process of establishing ghettos, it is unlikely that they were originally considered part of a systematic attempt to eliminate Jews completely.[204]
Himmler had a college degree in Agriculture and was interested in the health movement which began in Germany. He established a large farm just outside the Dachau camp where some of the prisoners worked. According to this news story, experiments were done on the farm to find out why potatoes had become so vulnerable to pests and early decay. Herbs were grown for use as medicine and vitamins were extracted from plants.

Initially, Schindler was mostly interested in the money-making potential of the business and hired Jews because they were cheaper than Poles—the wages were set by the occupying Nazi regime.[38] Later he began shielding his workers without regard for cost.[39] The status of his factory as a business essential to the war effort became a decisive factor enabling him to help his Jewish workers. Whenever Schindlerjuden (Schindler Jews) were threatened with deportation, he claimed exemptions for them. He claimed wives, children, and even people with disabilities were necessary mechanics and metalworkers.[39] On one occasion, the Gestapo came to Schindler demanding that he hand over a family that possessed forged identity papers. "Three hours after they walked in," Schindler said, "two drunk Gestapo men reeled out of my office without their prisoners and without the incriminating documents they had demanded."[40]
Even before the Nazis came to power in Germany in 1933, they had made no secret of their anti-Semitism. As early as 1919 Adolf Hitler had written, “Rational anti-Semitism, however, must lead to systematic legal opposition.…Its final objective must unswervingly be the removal of the Jews altogether.” In Mein Kampf (“My Struggle”; 1925–27), Hitler further developed the idea of the Jews as an evil race struggling for world domination. Nazi anti-Semitism was rooted in religious anti-Semitism and enhanced by political anti-Semitism. To this the Nazis added a further dimension: racial anti-Semitism. Nazi racial ideology characterized the Jews as Untermenschen (German: “subhumans”). The Nazis portrayed the Jews as a race and not as a religious group. Religious anti-Semitism could be resolved by conversion, political anti-Semitism by expulsion. Ultimately, the logic of Nazi racial anti-Semitism led to annihilation.

1945 Photo by George Rodger: "It wasn't even a matter of what I was photographing, as what had happened to me in the process. When I discovered that I could look at the horror of Belsen --4000 dead and starving lying around-- and think only of a nice photographic composition, I knew something had happened to me and I had to stop. I felt I was like the people running the camp --it didn't mean a thing." George Rodger in "Dialogue with photography", Dewi Lewis Publishing.

On April 15, 1945, British troops entered Bergen Belsen. They liberated some 60,000 prisoners, many of whom were on the verge of death. During the first weeks after liberation, close to 500 people in Bergen Belsen died every day. From liberation day until June 20, an estimated 14,000 people died from the terrible conditions that had been inflicted on them by the Nazis during the war.
^ 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]

In the final months of the war, SS guards moved camp inmates by train or on forced marches, often called “death marches,” in an attempt to prevent the Allied liberation of large numbers of prisoners. As Allied forces moved across Europe in a series of offensives against Germany, they began to encounter and liberate concentration camp prisoners, as well as prisoners en route by forced march from one camp to another. The marches continued until May 7, 1945, the day the German armed forces surrendered unconditionally to the Allies.
Paradoxically, at the same time that Germany tried to rid itself of its Jews via forced emigration, its territorial expansions kept bringing more Jews under its control. Germany annexed Austria in March 1938 and the Sudetenland (now in the Czech Republic) in September 1938. It established control over the Protectorate of Bohemia and Moravia (now in the Czech Republic) in March 1939. When Germany invaded Poland on September 1, 1939, the “Jewish question” became urgent. When the division of Poland between Germany and the Soviet Union was complete, more than two million more Jews had come under German control. For a time, the Nazis considered shipping the Jews to the island of Madagascar, off the southeast coast of Africa, but discarded the plan as impractical; the Nazis had not prevailed in the Battle of Britain, the seas had become a war zone, and the resources required for such a massive deportation were scarce.
Schindler started out as a wartime profiteer, having acquired an enamelware factory in Poland in 1939. At the height of his business, Schindler had 1,750 workers under his employment — 1000 of them Jewish. Over time, his daily interactions with his Jewish workers prompted him to use his political connections as a former German spy and his wealth to bribe Nazi officers to prevent his workers from being deported and killed. Through various Jewish administrators came what was known as "Schindler's List," although in reality, there were nine separate lists and Schindler, at the time, did not oversee the details since he was incarcerated for suspicion of bribery.
After the takeover of Bavaria on 9 March 1933, Heinrich Himmler, then Chief of Police in Munich, began to speak with the administration of an unused gunpowder and munitions factory. He toured the site to see if it could be used for quartering protective-custody prisoners. The Concentration Camp at Dachau was opened 22 March 1933, with the arrival of about 200 prisoners from Stadelheim Prison in Munich and the Landsberg fortress (where Hitler had written Mein Kampf during his imprisonment).[24] Himmler announced in the Münchner Neuesten Nachrichten newspaper that the camp could hold up to 5,000 people, and described it as "the first concentration camp for political prisoners" to be used to restore calm to Germany.[25] It became the first regular concentration camp established by the coalition government of the National Socialist German Worker's Party (Nazi Party) and the German National People's Party (dissolved on 6 July 1933).
under Zionist auspices there had been organized at Belsen a vast illegitimate trading organization with worldwide ramifications and dealing in a wide range of goods, principally precious metals and stones. A money market dealt with a wide range of currencies. Goods were being imported in cryptically marked containers consigned in UNRRA shipments to Jewish voluntary agencies ...
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.
The Soviets found 7,600 inmates in Auschwitz.[385] Some 60,000 prisoners were discovered at Bergen-Belsen by the British 11th Armoured Division;[386] 13,000 corpses lay unburied, and another 10,000 people died from typhus or malnutrition over the following weeks.[387] The BBC's war correspondent, Richard Dimbleby, described the scenes that greeted him and the British Army at Belsen, in a report so graphic the BBC declined to broadcast it for four days, and did so, on 19 April, only after Dimbleby had threatened to resign.[388]
In March 1944, part of the camp was redesignated as an Erholungslager ("recovery camp"),[11] where prisoners too sick to work were brought from other concentration camps. They were in Belsen supposedly to recover and then return to their original camps and resume work, but many of them died in Belsen of disease, starvation, exhaustion and lack of medical attention.[12]
