Hitler admired the British Empire and its colonial system as living proof of Germanic superiority over 'inferior' races and saw United Kingdom as Germany's natural ally.[59][60] He wrote in Mein Kampf: "For a long time to come there will be only two Powers in Europe with which it may be possible for Germany to conclude an alliance. These Powers are Great Britain and Italy."[60]
Our trip, full of suspense, took us past the baroque palace of Oranienburg, built at the time of Frederick the Great, through the sand of Brandenburg and through deserted pine forests, thence to a large settlement. Suddenly we saw in front of us high walls (about fourteen feet) which, at intervals of two hundred yards, were crowned by watchtowers, so that the whole camp gave the impression of a Chinese city as we knew it from pictures. We drove through an iron gate, and soon after through a second gate in a second inner wall about a hundred feet from the first one. In the space between the two walls there were barracks with administration and treasury buildings, and vegetable and other gardens. The inner gate, which led through the main watchtower, bore the inscription 'Work Makes Free'—an inscription which many inmates of the camp, after years of work and vain hope for release, will probably take as sarcasm.
To protect the supposed purity and strength of the Aryan race, the Nazis sought to exterminate Jews, Romani, Poles and most other Slavs, along with the physically and mentally handicapped. They disenfranchised and segregated homosexuals, Africans, Jehovah's Witnesses and political opponents.[10] The persecution reached its climax when the party-controlled German state set in motion the Final Solution–an industrial system of genocide which achieved the murder of an estimated 5.5 to 6 million Jews and millions of other targeted victims, in what has become known as the Holocaust.[11]
Women were a cornerstone of Nazi social policy. The Nazis opposed the feminist movement, claiming that it was the creation of Jewish intellectuals, instead advocating a patriarchal society in which the German woman would recognise that her "world is her husband, her family, her children, and her home".[264] Feminist groups were shut down or incorporated into the National Socialist Women's League, which coordinated groups throughout the country to promote motherhood and household activities. Courses were offered on childrearing, sewing, and cooking. Prominent feminists, including Anita Augspurg, Lida Gustava Heymann, and Helene Stöcker, felt forced to live in exile.[367] The League published the NS-Frauen-Warte, the only NSDAP-approved women's magazine in Nazi Germany;[368] despite some propaganda aspects, it was predominantly an ordinary woman's magazine.[369]
This intellectual preparation would probably not have been sufficient for the growth of Nazism in Germany but for that country’s defeat in World War I. The defeat and the resulting disillusionment, pauperization, and frustration—particularly among the lower middle classes—paved the way for the success of the propaganda of Hitler and the Nazis. The Treaty of Versailles (1919), the formal settlement of World War I drafted without German participation, alienated many Germans with its imposition of harsh monetary and territorial reparations. The significant resentment expressed toward the peace treaty gave Hitler a starting point. Because German representatives (branded the “November criminals” by National Socialists) agreed to cease hostilities and did not unconditionally surrender in the armistice of November 11, 1918, there was a widespread feeling—particularly in the military—that Germany’s defeat had been orchestrated by diplomats at the Versailles meetings. From the beginning, Hitler’s propaganda of revenge for this “traitorous” act, through which the German people had been “stabbed in the back,” and his call for rearmament had strong appeal within military circles, which regarded the peace only as a temporary setback in Germany’s expansionist program. The ruinous inflation of the German currency in 1923 wiped out the savings of many middle-class households and led to further public alienation and dissatisfaction.
One night in the autumn of 1944, two Frenchwomen—Loulou Le Porz, a doctor, and Violette Lecoq, a nurse—watched as a truck drove in through the main gates of Ravensbrück, the Nazi concentration camp for women. “There was a lorry,” Le Porz recalled, “that suddenly arrives and it turns around and reverses towards us. And it lifts up and it tips out a whole pile of corpses.” These were the bodies of Ravensbrück inmates who had died doing slave labor in the many satellite camps, and they were now being returned for cremation. Talking, decades later, to the historian and journalist Sarah Helm, whose new book, “Ravensbrück: Life and Death in Hitler’s Concentration Camp for Women” (Doubleday), recounts the stories of dozens of the camp’s inmates, Le Porz says that her reaction was simple disbelief. The sight of a truck full of dead bodies was so outrageous, so out of scale with ordinary experience, that “if we recount that one day, we said to each other, nobody would believe us.” The only way to make the scene credible would be to record it: “If one day someone makes a film they must film this scene. This night. This moment.”
Mendelian inheritance, or Mendelism, was supported by the Nazis, as well as by mainstream eugenicists of the time. The Mendelian theory of inheritance declared that genetic traits and attributes were passed from one generation to another.[104] Eugenicists used Mendelian inheritance theory to demonstrate the transfer of biological illness and impairments from parents to children, including mental disability, whereas others also utilised Mendelian theory to demonstrate the inheritance of social traits, with racialists claiming a racial nature behind certain general traits such as inventiveness or criminal behaviour.[105]
Precise numbers are still debated, but according to the US Holocaust Memorial Museum, the German SS systematically killed at least 960,000 of the 1.1-1.3 million Jews deported to the camp. Other victims included approximately 74,000 Poles, 21,000 Roma, 15,000 Soviet prisoners of war and at least 10,000 from other nationalities. More people died at Auschwitz than at any other Nazi concentration camp and probably than at any death camp in history.

SS formations committed many war crimes against civilians and allied servicemen.[238] From 1935 onward, the SS spearheaded the persecution of Jews, who were rounded up into ghettos and concentration camps.[239] With the outbreak of World War II, the SS Einsatzgruppen units followed the army into Poland and the Soviet Union, where from 1941 to 1945 they killed more than two million people, including 1.3 million Jews.[240] A third of the Einsatzgruppen members were recruited from Waffen-SS personnel.[241][242] The SS-Totenkopfverbände (death's head units) ran the concentration camps and extermination camps, where millions more were killed.[243][244] Up to 60,000 Waffen-SS men served in the camps.[245]

Nazi Germany maintained concentration camps (German: Konzentrationslager, KZ or KL) throughout the territories it controlled before and during the Second World War. The first Nazi camps were erected in Germany in March 1933 immediately after Hitler became Chancellor and his Nazi Party was given control of the police by Reich Interior Minister Wilhelm Frick and Prussian Acting Interior Minister Hermann Göring.[2] Used to hold and torture political opponents and union organizers, the camps initially held around 45,000 prisoners.[3] In 1933–1939, before the onset of war, most prisoners consisted of German Communists, Socialists, Social Democrats, Roma, Jehovah's Witnesses, homosexuals, and persons accused of 'asocial' or socially 'deviant' behavior by the Germans.[4]
