While civilian efforts had an impact on public opinion, the army was the only organisation with the capacity to overthrow the government.[443][444] A major plot by men in the upper echelons of the military originated in 1938. They believed Britain would go to war over Hitler's planned invasion of Czechoslovakia, and Germany would lose. The plan was to overthrow Hitler or possibly assassinate him. Participants included Generaloberst Ludwig Beck, Generaloberst Walther von Brauchitsch, Generaloberst Franz Halder, Admiral Wilhelm Canaris, and Generalleutnant Erwin von Witzleben, who joined a conspiracy headed by Oberstleutnant Hans Oster and Major Helmuth Groscurth of the Abwehr. The planned coup was cancelled after the signing of the Munich Agreement in September 1938.[445] Many of the same people were involved in a coup planned for 1940, but again the participants changed their minds and backed down, partly because of the popularity of the regime after the early victories in the war.[446][447] Attempts to assassinate Hitler resumed in earnest in 1943, with Henning von Tresckow joining Oster's group and attempting to blow up Hitler's plane in 1943. Several more attempts followed before the failed 20 July 1944 plot, which was at least partly motivated by the increasing prospect of a German defeat in the war.[448][449] The plot, part of Operation Valkyrie, involved Claus von Stauffenberg planting a bomb in the conference room at Wolf's Lair at Rastenburg. Hitler, who narrowly survived, later ordered savage reprisals resulting in the execution of more than 4,900 people.[450]
On 31 October 1922, a party with similar policies and objectives came into power in Italy, the National Fascist Party, under the leadership of the charismatic Benito Mussolini. The Fascists, like the Nazis, promoted a national rebirth of their country, as they opposed communism and liberalism; appealed to the working-class; opposed the Treaty of Versailles; and advocated the territorial expansion of their country. The Italian Fascists used a straight-armed Roman salute and wore black-shirted uniforms. Hitler was inspired by Mussolini and the Fascists, borrowing their use of the straight-armed salute as a Nazi salute. When the Fascists came to power in 1922 in Italy through their coup attempt called the "March on Rome", Hitler began planning his own coup.
When your relatives die, there’s usually a place you can go to pay your respects, like a cemetery with a grave where you can lay a stone and talk to them. The only place I have is Auschwitz and going back there for the first time will be the first and last chance I have to be able to return to the people I loved who I lost there and in other concentration camps.

When I finally returned to Czemierniki in 1993, despite the years in which Jews had lived there I could not find a trace either of my family or of Jewish life. Even the cemetery where my grandfather had been buried had been razed. The synagogue was gone. I went to ask the local priest, who said they had taken the tombstones and crushed them for building materials or something like that. I believe they deliberately destroyed any sign of Jewish life so as to be rid of us for ever.

The Nazi regime dominated neighbours through military threats in the years leading up to war. Nazi Germany made increasingly aggressive territorial demands, threatening war if these were not met. It seized Austria and Czechoslovakia in 1938 and 1939. Hitler made a non-aggression pact with Joseph Stalin and invaded Poland in September 1939, launching World War II in Europe. By early 1941, Germany controlled much of Europe. Reichskommissariats took control of conquered areas and a German administration was established in the remainder of Poland. Germany exploited the raw materials and labour of both its occupied territories and its allies. In the Holocaust, millions of Jews and other peoples deemed undesirable by the state were imprisoned, murdered in Nazi concentration camps and extermination camps, or shot.
Medical experiments, many of them pseudoscientific, were performed on concentration camp inmates beginning in 1941.[395] The most notorious doctor to perform medical experiments was SS-Hauptsturmführer Dr. Josef Mengele, camp doctor at Auschwitz.[396] Many of his victims died or were intentionally killed.[397] Concentration camp inmates were made available for purchase by pharmaceutical companies for drug testing and other experiments.[398]
A total of 22 main concentration camps (Stamlager) were established, together with approximately 1,200 affiliate camps. Besides these, thousands of smaller camps existed in all parts of German-controlled Europe. The 22 main camps, in alphabetical order, were as follows: Arbeitsdorf, Auschwitz, Bergen-Belsen, Buchenwald, Dachau, Flossenbürg, Gross-Rosen, Herzogenbosch, Kaunas, Krakow-Plaszow, Majdanek, Mauthausen, Mittelbau-Dora, Natzweiler-Struthof, Neuengamme, Ravensbrück, Riga-Kaiserwald, Sachsenhausen, Stutthof, Vaivara, Warsaw, Wewelsburg, Germany.
Auschwitz I, ul. Stanisławy Leszczyńskiej 11. The first camp to be used (called Stammlager by the Germans), consisting of old Polish Army barracks later converted into inmate housing, torture chambers, execution grounds, and SS administrative buildings. The infamous Arbeit macht frei gate is found here. Inside most of the barrack buildings are historical exhibits regarding the various nationalities held in the camp, video displays, photos, and personal belongings illustrating the life and cruelties of the Nazi terror. The only remaining gas chamber is found in Auschwitz I but note that, as indicated within the chamber, it was reconstructed to its wartime layout after the war.  edit
The Nazi Party's precursor, the Pan-German nationalist and antisemitic German Workers' Party, was founded on 5 January 1919. By the early 1920s the party was renamed the National Socialist German Workers' Party – to attract workers away from left-wing parties such as the Social Democrats (SPD) and the Communists (KPD) – and Adolf Hitler assumed control of the organization. The National Socialist Program or "25 Points" was adopted in 1920 and called for a united Greater Germany that would deny citizenship to Jews or those of Jewish descent, while also supporting land reform and the nationalization of some industries. In Mein Kampf ("My Struggle"; 1924–1925), Hitler outlined the anti-Semitism and anti-Communism at the heart of his political philosophy, as well as his disdain for representative democracy and his belief in Germany's right to territorial expansion.[5]
Following the camp's liberation, the Soviet government issued a statement, on 8 May 1945, that four million people had been killed on the site, a figure based on the capacity of the crematoria and later regarded as too high.[185] Höss told prosecutors at Nuremberg that at least 2,500,000 people had been murdered in Auschwitz by gassing and burning, and that another 500,000 had died of starvation and disease.[186] He testified that the figure of over two million had come from Eichmann.[187][d] In his memoirs, written in custody, he wrote that he regarded this figure as "far too high. Even Auschwitz had limits to its destructive possibilities."[189] Raul Hilberg's 1961 work, The Destruction of the European Jews, estimated that up to 1,000,000 Jews had died in Auschwitz.[190]
Auschwitz is enshrined in history in part because, as a work camp, there were survivors. Anita Lasker-Wallfisch was a 14-year-old Jewish cello student living in the German city of Breslau (now Wroclaw in Poland) when the war broke out. Two years later, she and her sister Renate were sent to work in a nearby paper factory. In 1942, after the Germans deported her parents to a death camp, the sisters doctored their identity papers and tried to escape.
Nazi Germany had a strong anti-tobacco movement, as pioneering research by Franz H. Müller in 1939 demonstrated a causal link between smoking and lung cancer.[389] The Reich Health Office took measures to try to limit smoking, including producing lectures and pamphlets.[390] Smoking was banned in many workplaces, on trains, and among on-duty members of the military.[391] Government agencies also worked to control other carcinogenic substances such as asbestos and pesticides.[392] As part of a general public health campaign, water supplies were cleaned up, lead and mercury were removed from consumer products, and women were urged to undergo regular screenings for breast cancer.[393]
Aware that as witnesses to the killings they would eventually be killed themselves, the Sonderkommandos of Birkenau Kommando III staged an uprising on 7 October 1944, following an announcement that some of them would be selected to be "transferred to another camp"—a common Nazi ruse for the murder of prisoners.[229][230] They attacked the SS guards with stones, axes, and makeshift hand grenades, which they also used to damage Crematorium IV and set it on fire. As the SS set up machine guns to attack the prisoners in Crematorium IV, the Sonderkommandos in Crematorium II also revolted, some of them managing to escape the compound.[230][231] The rebellion was suppressed by nightfall.[232]
Hayden’s comment, for example, that he had walked the ramp at Birkenau where women and children were separated, is essentially false; Jewish women with children arriving at Auschwitz were generally all murdered immediately upon arrival. After seeing the inside of the U.S. refugee facilities, we can also safely say they aren’t the kind of summer camps we would send our children to, either.

After the war, the Allied governments, such as the United States, Britain, and the Soviet Union, held trials for the Nazi leaders. These trials were held in Nuremberg, in Germany. For this reason, these trials were called "the Nuremberg Trials." The Allied leaders accused the Nazi leaders of war crimes and crimes against humanity, including murdering millions of people (in the Holocaust), of starting wars, of conspiracy, and belonging to illegal organizations like the Schutzstaffel (SS). Most Nazi leaders were found guilty by the court, and they were sent to jail or executed by hanging.
Nazis constructed gas chambers (rooms that filled with poison gas to kill those inside) to increase killing efficiency and to make the process more impersonal for the perpetrators. At the Auschwitz camp complex, the Birkenau killing center had four gas chambers. During the height of deportations to the camp in 1943-44, an average of 6,000 Jews were gassed there each day.
On January 20, 1942, fourteen such functionaries assembled at a lakeside villa outside Berlin to discuss a “Final Solution” to what was called “the Jewish problem.” What we now know as the Wannsee Conference put on paper plans that Hitler and his subordinates had been talking about for months. Of Europe’s 11 million Jews, those who could work would be worked to death, following the model already created at Auschwitz and other camps. Jews who were not selected for useful labor would be eliminated.
The first camp in Germany, Dachau, was founded in March 1933.[13] The press announcement said that "the first concentration camp is to be opened in Dachau with an accommodation for 5,000 people. All Communists and – where necessary – Reichsbanner and Social Democratic functionaries who endanger state security are to be concentrated there, as in the long run it is not possible to keep individual functionaries in the state prisons without overburdening these prisons."[13] Dachau was the first regular concentration camp established by the German coalition government of National Socialist Workers' Party (Nazi Party) and the Nationalist People's Party (dissolved on 6 July 1933). Heinrich Himmler, then Chief of Police of Munich, officially described the camp as "the first concentration camp for political prisoners."[13]
