Methods of mass murder evolved at local levels as well as being decreed from Nazi high command. Killing squads rounded up and shot entire Jewish communities. Over two days in Kiev, 33,771 Jews were shot. The murder of Jews rapidly escalated, in part because local Nazi leaders didn’t have enough room to place them in the ghettos. By the end of the year, plans to implement the systematic slaughter of Jews by using gas in mobile trucks and gas chambers were well underway.
Bergen-Belsen was first established in 1940 as a prisoner of war camp. From 1943, Jewish civilians with foreign passports were held as ‘leverage’ in possible exchanges for Germans interned in Allied countries or for money. It later became a concentration camp and was used as a collection centre for survivors of the death marches. The camp became exceptionally overcrowded and, as a result of the Germans’ neglect, conditions were allowed to deteriorate further in the last months of the war, causing many more deaths.
In 1993, Steven Spielberg’s Schindler’s List brought to the screen a story that had gone untold since the tragic events of the Holocaust. Oskar Schindler, a Nazi party member, used his pull within the party to save the lives of more than 1000 Jewish individuals by recruiting them to work in his Polish factory. Here are some facts about Spielberg’s groundbreaking film on its 25th anniversary.
Most of the survivors in the DP camp at Bergen Belsen were young people. They found themselves entirely alone, having lost their parents, spouses, children and siblings during the Holocaust. They commonly chose to establish a feeling of normality and fight despair by marrying in the DP camp. During the first year after liberation, in the Bergen Belden DP camp, there were often six weddings a day, and up to fifty weddings a week. During 1946, there were 1,070 weddings at Bergen Belsen. 
The prisoners of Dachau concentration camp originally were to serve as forced labor for a munition factory, and to expand the camp. It was used as a training center for SS guards and was a model for other concentration camps.[28] The camp was about 300 m × 600 m (1,000 ft × 2,000 ft) in rectangular shape. The prisoners' entrance was secured by an iron gate with the motto "Arbeit macht frei" ("Work will make you free"). This reflected Nazi propaganda, which trivialized concentration camps as labor and re-education camps, when in fact forced labor was used as a method of torture and murder.[29]

After the German surrender on May 7, 1945, the American Army took over the barracks of the SS garrison and set up a command post called Eastman which they occupied until 1973. On the orders of General Dwight D. Eisenhower, all available American soldiers were brought to Dachau so that they could be eye-witnesses to the existence of the homicidal gas chamber, disguised as a shower room.

During the era of the Holocaust, German authorities also targeted other groups because of their perceived racial and biological inferiority: Roma (Gypsies), people with disabilities, and some of the Slavic peoples (Poles, Russians, and others). Other groups were persecuted on political, ideological, and behavioral grounds, among them Communists, Socialists, Jehovah's Witnesses, and homosexuals.
On April 15, 1945, Bergen-Belsen was liberated by the Allied 21st Army Group, a combined British-Canadian unit. At the time of liberation, the camp had been without food or water for three to five days. As Matthew Nesbitt, a Canadian liberator, recounted, "…the first thing we had to do when we got to camp. Prior to even distributing the food. And that was to make sure we used the guards to separate the living from the dead, from the huts, because first of all, if we are going to save anybody, we had to know who was alive and who had to be buried…The only way you could do that was to go into each individual hut and shake whoever was on that little slab…if they didn't move, they were dead."
In Dachau, as in other Nazi camps, German physicians performed medical experiments on prisoners, including high-altitude experiments using a decompression chamber, malaria and tuberculosis experiments, hypothermia experiments, and experiments testing new medications. Prisoners were also forced to test methods of making seawater potable and of halting excessive bleeding.
Germany invaded the Soviet Union in June 1941.[236] German propaganda portrayed the war against the Soviet Union as both an ideological war between German National Socialism and Jewish Bolshevism and a racial war between the Germans and the Jewish, Romani and Slavic Untermenschen ("sub-humans").[237] Local populations in some occupied Soviet territories actively participated in the killing of Jews and others, and helped identify and round up Jews.[238] German involvement ranged from active instigation and involvement to general guidance.[239] In Lithuania, Latvia, and western Ukraine, locals were deeply involved in the murder of Jews from the beginning of the German occupation. Some of these Latvian and Lithuanian units also participated in the murder of Jews in Belarus. In the south, Ukrainians killed about 24,000 Jews and some went to Poland to serve as concentration and death-camp guards.[238] Military units from some countries allied to Germany also killed Jews. Romanian units were given orders to exterminate and wipe out Jews in areas they controlled.[240] Ustaše militia in Croatia persecuted and murdered Jews, among others.[168] Many of the killings were carried out in public, a change from previous practice.[241]
^ Jump up to: a b Eberhard Jäckel (Die Zeit, 1986): "Ich behaupte ... daß der nationalsozialistische Mord an den Juden deswegen einzigartig war, weil noch nie zuvor ein Staat mit der Autorität seines verantwortlichen Führers beschlossen und angekündigt hatte, eine bestimmte Menschengruppe einschließlich der Alten, der Frauen, der Kinder und der Säuglinge möglichst restlos zu töten, und diesen Beschluß mit allen nur möglichen staatlichen Machtmitteln in die Tat umsetzte." ("I maintain ... that the National Socialist killing of the Jews was unique in that never before had a state with the authority of its leader decided and announced that a specific group of humans, including the elderly, the women, the children and the infants, would be killed as quickly as possible, and then carried out this resolution using every possible means of state power.")[35]
Before and after the March 1933 Reichstag elections, the Nazis intensified their campaign of violence against opponents.[77] They set up concentration camps for extrajudicial imprisonment.[78] One of the first, at Dachau, opened on 9 March 1933.[79] Initially the camp contained mostly Communists and Social Democrats.[80] Other early prisons were consolidated by mid-1934 into purpose-built camps outside the cities, run exclusively by the SS.[81] The initial purpose of the camps was to serve as a deterrent by terrorizing Germans who did not conform.[82]
From 1933 until 1938, most of the people held in concentration camps were political prisoners and people the Nazis labeled as "asocial." These included the disabled, the homeless, and the mentally ill. After Kristallnacht in 1938, the persecution of Jews became more organized. This led to the exponential increase in the number of Jews sent to concentration camps.
The total number of deaths in the first five months of 1945 was almost half the total deaths in the 12-year history of the camp. The death rate in the other Nazi concentration camps also rose dramatically in the last months of the war, as the typhus epidemic spread throughout Germany. American POWs in German camps were saved from the epidemic by booster shots of typhus vaccine sent to them from America by the International Red Cross. The Germans were conducting experiments at the Buchenwald camp in an effort to develop a vaccine for typhus, but had not been successful. After the war, the doctors who had attempted to develop a typhus vaccine at Buchenwald were put on trial as war criminals at Nuremberg in the Doctor's Trial conducted by Americans.

No matter the ethical background of a student, the lesson that true good and true evil exist in the world is invaluable. This can be a difficult concept to convey without controversy. The concept of what is good and what is evil is not constant. This changes from person to person based on belief. There is, however, an area of absolutes that ought to be discussed so that students can know where and when to take a stand and for what cause. There are a few examples from history that can be used to have this discussion productively. One such example is the Nazi Holocaust. This terrifying case has absolutes that do not change. Thus persons and events from World War II can be used as examples of good and evil, and therefore can lead to productive discussions of ethics. A very good text to use in order to encourage this discussion is Schindler’s List by Thomas Keneally.

Holocaust, Hebrew Shoʾah (“Catastrophe”), Yiddish and Hebrew Ḥurban (“Destruction”), the systematic state-sponsored killing of six million Jewish men, women, and children and millions of others by Nazi Germany and its collaborators during World War II. The Germans called this “the final solution to the Jewish question.” Yiddish-speaking Jews and survivors in the years immediately following their liberation called the murder of the Jews the Ḥurban, the word used to describe the destruction of the First Temple in Jerusalem by the Babylonians in 586 bce and the destruction of the Second Temple by the Romans in 70 ce. Shoʾah (“Catastrophe”) is the term preferred by Israelis and the French, most especially after Claude Lanzmann’s masterful 1985 motion picture documentary of that title. It is also preferred by people who speak Hebrew and by those who want to be more particular about the Jewish experience or who are uncomfortable with the religious connotations of the word Holocaust. Less universal and more particular, Shoʾah emphasizes the annihilation of the Jews, not the totality of Nazi victims. More particular terms also were used by Raul Hilberg, who called his pioneering work The Destruction of the European Jews, and Lucy S. Dawidowicz, who entitled her book on the Holocaust The War Against the Jews. In part she showed how Germany fought two wars simultaneously: World War II and the racial war against the Jews. The Allies fought only the World War. The word Holocaust is derived from the Greek holokauston, a translation of the Hebrew word ʿolah, meaning a burnt sacrifice offered whole to God. This word was chosen because in the ultimate manifestation of the Nazi killing program—the extermination camps—the bodies of the victims were consumed whole in crematoria and open fires.
Young boys of the Hitler Youth were brought to see the dead bodies on the train. Mutilated corpses of SS guards, who had been killed by the Americans after discovering the train, were lying nearby. Before the corpses in the camp were finally given a decent burial, the stench could be smelled up to a mile away, according to the American liberators. When the bodies of the typhus victims were finally taken to the cemetery on a hill called Leitenberg for burial by the citizens of Dachau, the horse-drawn wagons had to be driven slowly though the town, on the orders of the American military, so that the town's people would be forced to confront the horror of what the Nazis had done.
These evacuations were regarded as provisional or "temporary solutions" ("Ausweichmöglichkeiten").[266][p] The final solution would encompass the 11 million Jews living not only in territories controlled by Germany, but elsewhere in Europe and adjacent territories, such as Britain, Ireland, Switzerland, Turkey, Sweden, Portugal, Spain, and Hungary, "dependent on military developments".[266] There was little doubt what the final solution was, writes Peter Longerich: "the Jews were to be annihilated by a combination of forced labour and mass murder".[268]

They built roads, worked in gravel pits, and drained marshes, reclaiming them as arable land, initially, production in the camps was directly under the control of the individual camp commandant. But as the camps continued to grow, the range of production expanded, and the SS industries that were served by the camp labour were centralised under their main office in Berlin. In the first winter of the war the Dachau camp was used to set up the SS Totenkopf Division.
In spite of the Jewish "holy war" against the Nazis, there were no Jews sent to a concentration camp solely because they were Jewish during the first five and a half years that the Nazi concentration camps were in existence. Jews were sent to Dachau from day one, but it was because they were Communists or trade union leaders, not because they were Jewish. The first Jews to be taken into "protective custody," simply because they were Jews, were arrested during the pogrom on the night of November 9th & 10th in 1938, which the Nazis named Kristallnacht (Night of Broken Glass).
In early 1937, the SS, using prisoner labor, began construction of a large complex of buildings on the grounds of the original camp. Prisoners were forced to do this work, starting with the destruction of the old munitions factory, under terrible conditions. The construction was officially completed in mid-August 1938 and the camp remained essentially unchanged until 1945. Dachau thus remained in operation for the entire period of the Third Reich.

On March 7, 1933, an important law was passed by the newly-elected German Congress, which called for all high-level government officials in the German states to be appointed by the Nazis and for all state government positions to be supervised by the Nazis in the event of an emergency. Germany was already in an emergency situation and Article 48 of the German Constitution had already been invoked. Under this new law, Heinrich Himmler was appointed the acting Chief of Police in Munich, although his real job was Reichsführer-SS, the leader of Hitler's elite private Army.
Writer Herbert Steinhouse, who interviewed him in 1948, wrote that "Schindler's exceptional deeds stemmed from just that elementary sense of decency and humanity that our sophisticated age seldom sincerely believes in. A repentant opportunist saw the light and rebelled against the sadism and vile criminality all around him."[39] In a 1983 television documentary, Schindler was quoted as saying, "I felt that the Jews were being destroyed. I had to help them; there was no choice."[90]
In December 1944 SS-Hauptsturmführer Josef Kramer, previously at Auschwitz-Birkenau, became the new camp commandant, replacing SS-Hauptsturmführer Adolf Haas [de], who had been in post since the spring of 1943.[7] In January 1945, the SS took over the POW hospital and increased the size of Bergen-Belsen. As eastern concentration camps were evacuated before the advance of the Red Army, at least 85,000 people were transported in cattle cars or marched to Bergen-Belsen.[14] Before that the number of prisoners at Belsen had been much smaller. In July 1944 there were 7,300; by December 1944 the number had increased to 15,000; and by February 1945 it had risen to 22,000. Numbers then soared to around 60,000 by April 15, 1945.[7] This overcrowding led to a vast increase in deaths from disease: particularly typhus, as well as tuberculosis, typhoid fever, dysentery and malnutrition in a camp originally designed to hold about 10,000 inmates. At this point also, the special status of the exchange prisoners no longer applied. All inmates were subject to starvation and epidemics.[14]
