When the Nazi’s rose to power they built facilities to hold and, eventually kill, their enemies. When the first concentration camps were built in 1933, this primarily meant political dissidents and opponents of the Nazi government, such as German Communists, Socialists, Social Democrats but would grow to include asocial groups – Gypsies, Jehovah’s Witnesses, the homeless, the mentally ill and homosexuals.  It was not until Kristallnacht that the prisoners became primarily Jewish.
During the liberation of the sub-camps surrounding Dachau, advance scouts of the U.S. Army's 522nd Field Artillery Battalion, a segregated battalion consisting of Nisei, 2nd generation Japanese-Americans, liberated the 3,000 prisoners of the "Kaufering IV Hurlach"[85] slave labor camp.[86] Perisco describes an Office of Strategic Services (OSS) team (code name LUXE) leading Army Intelligence to a "Camp IV" on 29 April. "They found the camp afire and a stack of some four hundred bodies burning ... American soldiers then went into Landsberg and rounded up all the male civilians they could find and marched them out to the camp. The former commandant was forced to lie amidst a pile of corpses. The male population of Landsberg was then ordered to walk by, and ordered to spit on the commandant as they passed. The commandant was then turned over to a group of liberated camp survivors".[87] The 522nd's personnel later discovered the survivors of a death march[88] headed generally southwards from the Dachau main camp to Eurasburg, then eastwards towards the Austrian border on 2 May, just west of the town of Waakirchen.[89][90]

On April 16, 1945 Soviets surrounded Berlin, Germany’s capital. When the Soviets began advancing towards the Reich Chancellery, Hitler committed suicide on April 30, 1945. Then on May 7th, Germany surrendered to the Western Allies in Reims, France and a few days later to the Soviets in Berlin. All told more than 60 million people, or about 3% of the world’s population at the time, were killed during the course of the Second World War.

Dachau was mainly a camp for Communist political prisoners and anti-Fascist resistance fighters who were captured in the Nazi-occupied countries. On the day of the liberation of Dachau, the political prisoners were in control, as Commandant Wilhelm Eduard Weiter had left the camp on April 26, 1945, along with a transport of prisoners who were being evacuated to Schloss Itter, a subcamp of Dachau in Austria. Former Commandant Martin Gottfried Weiss was in charge of the camp for two days until he fled, along with most of the regular guards, on the night of April 28, 1945.

What you will see here is the final and utter condemnation of the Nazi party. It justifies every measure the United Nations will take to exterminate that party. What you will see here is such a disgrace to the German people that their names must be erased from the list of civilized nations [...] It is your lot to begin the hard task of restoring the name of the German people [...] But this cannot be done until you have reared a new generation amongst whom it is impossible to find people prepared to commit such crimes; until you have reared a new generation possessing the instinctive good will to prevent a repetition of such horrible cruelties. We will now begin our tour.
At Auschwitz, after the chambers were filled, the doors were shut and pellets of Zyklon-B were dropped into the chambers through vents,[293] releasing toxic prussic acid, or hydrogen cyanide.[294] Those inside died within 20 minutes; the speed of death depended on how close the inmate was standing to a gas vent, according to the commandant Rudolf Höss, who estimated that about one-third of the victims died immediately.[295] Johann Kremer, an SS doctor who oversaw the gassings, testified that: "Shouting and screaming of the victims could be heard through the opening and it was clear that they fought for their lives."[296] The gas was then pumped out, the bodies were removed, gold fillings in their teeth were extracted, and women's hair was cut.[297] The work was done by the Sonderkommando, work groups of mostly Jewish prisoners.[298] At Auschwitz, the bodies were at first buried in deep pits and covered with lime, but between September and November 1942, on the orders of Himmler, they were dug up and burned. In early 1943, new gas chambers and crematoria were built to accommodate the numbers.[299]
Weiss had previously been the Commandant of the Neuengamme concentration camp from 1940 to 1942. From September 1942 until the end of October 1943, Weiss was the Commandant of Dachau. During his time as the Commandant of Dachau, some of the worst atrocities had occurred, including the building of the gas chamber and the medical experiments conducted for the German air force. In spite of this, several former prisoners testified in his defense when he was put on trial at Dachau in the first American Military Tribunal in November 1945.
Albert Goering loathed all of Nazism's inhumanity and at the risk of his career, fortune and life, used his name and connections to save hundreds of Jews and and political dissidents during the Second World War. After the war Albert Goering - savior of victims of the tyranny his brother helped create - was imprisoned for several years for his name alone. But his story is almost unknown: he was shoved into obscurity by the enormity of his brother's crimes.
The United States Holocaust Memorial Museum defines the Holocaust as the "systematic, bureaucratic, state-sponsored persecution and murder of six million Jews by the Nazi regime and its collaborators",[29] distinguishing between the Holocaust and the targeting of other groups during "the era of the Holocaust".[30] According to Yad Vashem, Israel's Holocaust memorial, most historians regard the start of the "Holocaust era" as January 1933, when Hitler was named Chancellor of Germany.[31] Other victims of the Holocaust era include those viewed as inferior, including for reasons of race or ethnicity (such as the Roma, ethnic Poles, Russians, and the disabled); and those targeted because of their beliefs or behavior (such as Jehovah's Witnesses, communists, and homosexuals).[30] Hitler came to see the Jews as "uniquely dangerous to Germany", according to Peter Hayes, "and therefore uniquely destined to disappear completely from the Reich and all territories subordinate to it". The persecution and murder of other groups was much less consistent. For example, he writes, the Nazis regarded the Slavs as "sub-human", but their treatment consisted of "enslavement and gradual attrition", while "some Slavs—Slovaks, Croats, Bulgarians, some Ukrainians—[were] allotted a favored place in Hitler's New Order".[20]

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.
Man blinded by continuous beatings  © The ideas and emotions that lay behind the Holocaust were not new, nor were they uniquely German. The Nazis were the heirs of a centuries-old tradition of Jew-hatred, rooted in religious rivalry and found in all European countries. When the Nazis came to carry out their genocidal programme, they found collaborators in all the countries they dominated, including governments that enjoyed considerable public support. Most people drew the line at mass murder, but relatively few could be found to oppose it actively or to extend help to the Jews.
Though it had ancient roots, Nazi ideology was far from a primitive, medieval throwback - it was capable of appealing to intelligent and sophisticated people. Many high-ranking Nazis had doctoral degrees and early supporters included such eminent people as philosopher Martin Heidegger, theologian Martin Niemoeller, and commander-in-chief of German forces in the First World War, General Erich Ludendorff. Hitler appealed with a powerful vision of a strong, united and 'racially' pure Germany, bolstered by pseudo-scientific ideas that were popular at the time.
From the earliest years of the Nazi regime, German authorities persecuted homosexuals and others whose behavior did not match prescribed social norms. German police officials targeted thousands of political opponents (including Communists, Socialists, and trade unionists) and religious dissidents (such as Jehovah's Witnesses). Many of these individuals died as a result of incarceration and maltreatment.
The name 'Belsen' invokes tremor in Jews' hearts. Belsen is engraved in the Jewish consciousness as one of the most cursed places in Germany, where the bones of tens of thousands of Jewish victims are buried. The Belsen camp is, in Jews' memories and in the memories of all people in the world, a camp of starvation, and unbelievable filth which caused diseases and plagues. Belsen has become a symbol of man's inhumanity to man.
The anti-Hitler movement inside Germany, which included German communists and Jehovah's Witnesses, was the largest indigenous resistance movement of any country during the whole war. Only in Germany was an attempt made to assassinate their leader. Around 800,000 were sent to prison at one time or another for active resistance to the regime. While the western allies did all in their power to help other resistance movements, ie in France and the Netherlands, they did nothing to help or encourage the movement in Germany which in all probability could have ended the war sooner. But the Allies were intent on unconditional surrender and refused to make any deals at all with Germans. Accordingly the Allies viewed all Germans as bad, not only Nazis.
In his 1983 book, Popular Opinion and Political Dissent in the Third Reich, Ian Kershaw examined the Alltagsgeschichte (history of everyday life) in Bavaria during the Nazi period. The most common viewpoint of Bavarians was indifference towards what was happening to the Jews, he wrote. Most Bavarians were vaguely aware of the genocide, but they were vastly more concerned about the war.[472] Kershaw argued that "the road to Auschwitz was built by hate, but paved with indifference".[473] His assessment faced criticism from historians Otto Dov Kulka and Michael Kater. Kater maintained that Kershaw had downplayed the extent of popular antisemitism. Although most of the "spontaneous" antisemitic actions of Nazi Germany had been staged, Kater argued that these had involved substantial numbers of Germans, and therefore it was wrong to view the extreme antisemitism of the Nazis as coming solely from above.[474] Kulka argued that "passive complicity" would be a better term than "indifference".[475] Focusing on the views of Germans opposed to the Nazi regime, the German historian Christof Dipper, in his essay "Der Deutsche Widerstand und die Juden" (1983), argued that the majority of the anti-Nazi national-conservatives were antisemitic. No one in the German resistance supported the Holocaust, but Dipper wrote that the national conservatives did not intend to restore civil rights to the Jews after the planned overthrow of Hitler.[474]

Weather at the time of liberation was unseasonably cool and temperatures trended down through the first two days of May; on 2 May, the area received a snowstorm with 10 centimetres (4 in) of snow at nearby Munich.[91] Proper clothing was still scarce and film footage from the time (as seen in The World at War) shows naked, gaunt people either wandering on snow or dead under it.

Responding to domestic pressures to act on behalf of Jewish refugees, U.S. Pres. Franklin D. Roosevelt convened, but did not attend, the Évian Conference on resettlement, in Évian-les-Bains, France, in July 1938. In his invitation to government leaders, Roosevelt specified that they would not have to change laws or spend government funds; only philanthropic funds would be used for resettlement. Britain was assured that Palestine would not be on the agenda. The result was that little was attempted and less accomplished.
Many of the naked corpses found in the camp were left out until May 13, two weeks after the liberation, so that American Congressmen, newspaper reporters and as many American soldiers as possible could view the horror. Thirty male citizens from the town of Dachau were brought to the camp and forced to view the rotting corpses, even though the typhus epidemic was still raging in the camp, and the Germans had not been vaccinated.
The Germans required each ghetto to be run by a Judenrat, or Jewish council.[205] Councils were responsible for a ghetto's day-to-day operations, including distributing food, water, heat, medical care, and shelter. The Germans also required councils to confiscate property, organize forced labor, and, finally, facilitate deportations to extermination camps.[206] The councils' basic strategy was one of trying to minimize losses, by cooperating with German authorities, bribing officials, and petitioning for better conditions or clemency.[207]

Then as a last straw the Allies bombed the electric plant that pumped our water. Loads of food were unable to reach the camp because of the Allied fighters. Then things really got out of hand. During the last six weeks I have been helpless. I did not even have sufficient staff to bury the dead, let alone segregate the sick ... I tried to get medicines and food for the prisoners and I failed. I was swamped. I may have been hated, but I was doing my duty.
As the Amper River would divert into backwaters in several places, there were many fords making it possible to cross the river. The oldest findings of human presence here date back to the Stone Age. The most noteworthy findings were discovered near Feldgeding in the adjoining municipality Bergkirchen. Around 1000 B.C. the Celts arrived in this area and settled. The name “Dachau” originated in the Celtic Dahauua, which roughly translates to “loamy meadow” and also alludes to the loamy soil of the surrounding hills. Some theories assume the name “Amper” river may derive from the Celtic word for “water”. Approximately at the turn of the first millennium the Romans conquered the area and incorporated it into the province of Rhaetia. A Roman trade road between Salzburg and today’s Augsburg is said to have run through Dachau. Remains of this old route are found along the Amper marshlands.

Dachau was the first and most important camp at which German doctors and scientists set up laboratories using inmates as involuntary guinea pigs for such experiments as determining the effects on human beings of sudden increases and decreases in atmospheric pressure, studying the effects of freezing on warm-blooded creatures, infecting prisoners with malaria and treating them with various drugs with unknown effects, and testing the effects of drinking seawater or going without food or water. Continued throughout World War II, such experiments and the harsh living conditions made Dachau one of the most notorious of camps. After the war, the scientists and doctors from this and other camps were tried at Nürnberg in the “Doctors’ Trial”; seven were sentenced to death. (See Nürnberg trials.)
I was surprised to find records, going back for two or three years, of large quantities of food cooked daily for distribution. I became convinced, contrary to popular opinion, that there had never been a policy of deliberate starvation. This was confirmed by the large numbers of well-fed inmates. Why then were so many people suffering from malnutrition?... The major reasons for the state of Belsen were disease, gross overcrowding by central authority, lack of law and order within the huts, and inadequate supplies of food, water and drugs.
When British and Canadian troops finally entered they found over 13,000 unburied bodies and (including the satellite camps) around 60,000 inmates, most acutely sick and starving. The prisoners had been without food or water for days before the Allied arrival, partially due to allied bombing. Immediately before and after liberation, prisoners were dying at around 500 per day, mostly from typhus.[18] The scenes that greeted British troops were described by the BBC's Richard Dimbleby, who accompanied them:
