The composition of the inmates reflected the Nazis’ changing choice of victims. The first inmates were Social Democrats, Communists, and other political prisoners. Throughout its existence, Dachau remained a “political camp,” in which political prisoners retained a prominent role. Later victims included Roma (Gypsies) and homosexuals, as well as Jehovah’s Witnesses. Jews were brought to Dachau after Kristallnacht in November 1938. Initially, Jews could be freed if they had a way out of Germany. When the systematic killing of Jews began in 1942, many were sent from Dachau to the extermination camps. Dachau received Jews again after the “death marches” of the winter of 1944–45. These marches, following the forcible evacuation of the extermination camps, were one of the final phases of the Holocaust.

In 1942, fifteen Nazi leaders met at a conference in Wannsee, Germany to discuss the “Jewish Question”. Their job was to decide the most efficient way to exterminate the Jews. They decided that Jews would be sent to extermination camps where they would be sent to showers. But instead of water coming out of the faucet, they faced their death when poisonous Zyklon-B gas leaked through the showerheads to suffocate them. This decision at the conference is called the “Final Solution.”

Oskar Schindler left school in 1924, taking odd jobs and trying to find a direction in life. In 1928, he met and married Emilie Pelzl and soon after was called into military service. Afterward, he worked for his father’s company until the business failed in the economic depression of the 1930s. When not working, Schindler excelled at drinking and philandering, a lifestyle he would maintain throughout much of his life.

Due to horrific overcrowding and the spread of contagious diseases brought from what is now Poland by new arrivals who had been evacuated from the death camps, the number of recorded deaths at Dachau in the last four chaotic months of the war jumped to 13,158. After the camp was liberated by the US Seventh Army on April 29, 1945, an additional 2,226 prisoners died from disease in the month of May and 196 more died in June.

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 invasion of Poland, the Germans planned to set up a Jewish reservation in southeast Poland around the transit camp in Nisko, but the "Nisko Plan" failed, in part because it was opposed by Hans Frank, the new Governor-General of the General Government territory.[147][148][149] Adolf Eichmann was assigned to remove Jews from Germany, Austria, and the Protectorate of Bohemia and Moravia to the reservation.[150] Although the idea was to remove 80,000 Jews, Eichmann had managed to send only 4,700 by March 1940, and the plan was abandoned in April.[151] By mid-October the idea of a Jewish reservation had been revived by Heinrich Himmler, because of the influx of Germanic settlers into the Warthegau.[152] Resettlement continued until January 1941 under Odilo Globocnik,[153] and included both Jews and Poles.[154] By that time 95,000 Jews were already concentrated in the area,[155] but the plan to deport up to 600,000 additional Jews to the Lublin reservation failed for logistical and political reasons.[156]
Mr. Le Drieullenac said that as he helped to drag the bodies he noticed many had wounds at the top of the thigh. “First I thought they were gunshot wounds,” he told. the court to-day. “Then I saw that they could not be and a friend told me that men were cutting bits out of the bodies to eat them. When I went into the but to another body I saw a man take a knife and, looking to see if he was unobserved, cut a piece of flesh from the body and put it in his mouth. You can imagine the condition to which the men had been reduced to run the risk of eating flesh taken from a body turned black.”
In early 1937, the SS, using prisoner labor, initiated 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. The area in Dachau included other SS facilities beside the concentration camp—a leader school of the economic and civil service, the medical school of the SS, etc. The KZ (Konzentrationslager) at that time was called a “protective custody camp,” and occupied less than half of the area of the entire complex.

The excuse for setting up concentration camps, including the Dachau camp, was the hysteria following the burning of the Reichstag, which was the Congressional building in Berlin, on the night of February 27, 1933, only four weeks after Adolf Hitler was sworn in as Chancellor of Germany. Hermann Goering accused the Communists of starting the fire in protest of the appointment of Hitler as the Chancellor and the scheduled Congressional election to confirm his appointment, but the Communists claimed that the Nazis had set the fire themselves in order to begin a reign of terror. The arrests of Communists and Social Democrats began even before the fire was put out.

On the night of 9-10 November 1938, Nazi Propaganda Minister Dr Josef Goebbels organised the violent outburst known as Kristallnacht ('Crystal Night', the night of broken glass). While the police stood by, Nazi stormtroopers in civilian clothes burned down synagogues and broke into Jewish homes throughout Germany and Austria, terrorising and beating men, women and children. Ninety-one Jews were murdered and over 20,000 men were arrested and taken to concentration camps. Afterwards the Jewish community was fined one billion Reichsmarks to pay for the damage.
Owing to the severe refugee crisis mainly caused by the expulsions of ethnic Germans, the camp was from late 1948 used to house 2000 Germans from Czechoslovakia (mainly from the Sudetenland). This settlement was called Dachau-East, and remained until the mid-1960s.[113] During this time, former prisoners banded together to erect a memorial on the site of the camp, finding it unbelievable that there were still people (refugees) living in the former camp.[citation needed]
Außenlager Unterlüß-Altensothrieth (Tannenberglager) east of Bergen was in use from late August 1944 to April 13, 1945. It was located at Unterlüß, where the Rheinmetall-Borsig AG had a large test site. Up to 900 female Polish, Hungarian, Romanian, Yugoslavian and Czech Jews had to clear forest, do construction work or work in munitions production.[10]:204
