However, it was the effects of the Great Depression in Germany that brought the Nazi Party to its first real nationwide importance. The rapid rise in unemployment in 1929–30 provided millions of jobless and dissatisfied voters whom the Nazi Party exploited to its advantage. From 1929 to 1932 the party vastly increased its membership and voting strength; its vote in elections to the Reichstag (the German Parliament) increased from 800,000 votes in 1928 to about 14,000,000 votes in July 1932, and it thus emerged as the largest voting bloc in the Reichstag, with 230 members (38 percent of the total vote). By then big-business circles had begun to finance the Nazi electoral campaigns, and swelling bands of SA toughs increasingly dominated the street fighting with the communists that accompanied such campaigns.
Johann Gottlieb Fichte accused Jews in Germany of having been and inevitably of continuing to be a "state within a state" that threatened German national unity. Fichte promoted two options in order to address this, his first one being the creation of a Jewish state in Palestine so the Jews could be impelled to leave Europe. His second option was violence against Jews and he said that the goal of the violence would be "to cut off all their heads in one night, and set new ones on their shoulders, which should not contain a single Jewish idea".
The new Jewish pavilion opened in 2013. It was designed by Yad Vashem, the Holocaust memorial in Jerusalem. It shows black-and-white films of Jewish life in Europe before the war, then of Hitler’s rallies. In one room, the Israeli artist Michal Rovner has copied children’s drawings from the camp onto the wall. In another, names of some of the six million Holocaust dead are printed on a long row of pages, their edges yellowing from human touch.
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.”
The first German concentration camps were established in 1933 for the confinement of opponents of the Nazi Party—Communists and Social Democrats. Political opposition soon was enlarged to include minority groups, chiefly Jews, but by the end of World War II many Roma, homosexuals, and anti-Nazi civilians from the occupied territories had also been liquidated. After the outbreak of World War II the camp inmates were used as a supplementary labour supply, and such camps mushroomed throughout Europe. Inmates were required to work for their wages in food; those unable to work usually died of starvation, and those who did not starve often died of overwork. The most shocking extension of this system was the establishment after 1940 of extermination centres, or “death camps.” They were located primarily in Poland, which Adolf Hitler had selected as the setting for his “final solution” to the “Jewish problem.” The most notorious were Auschwitz, Majdanek, and Treblinka. (See extermination camp.) At some camps, notably Buchenwald, medical experimentation was conducted. New toxins and antitoxins were tried out, new surgical techniques devised, and studies made of the effects of artificially induced diseases, all by experimenting on living human beings.
Most Germans were relieved that the conflicts and street fighting of the Weimar era had ended. They were deluged with propaganda orchestrated by Minister of Public Enlightenment and Propaganda Joseph Goebbels, who promised peace and plenty for all in a united, Marxist-free country without the constraints of the Versailles Treaty. The NSDAP obtained and legitimised power through its initial revolutionary activities, then through manipulation of legal mechanisms, the use of police powers, and by taking control of the state and federal institutions. The first major Nazi concentration camp, initially for political prisoners, was opened at Dachau in 1933. Hundreds of camps of varying size and function were created by the end of the war.
Losses continued to mount after Stalingrad, leading to a sharp reduction in the popularity of the Nazi Party and deteriorating morale.  Soviet forces continued to push westward after the failed German offensive at the Battle of Kursk in the summer of 1943. By the end of 1943 the Germans had lost most of their eastern territorial gains. In Egypt, Field Marshal Erwin Rommel's Afrika Korps were defeated by British forces under Field Marshal Bernard Montgomery in October 1942. The Allies landed in Sicily in July 1943 and in Italy in September. Meanwhile, American and British bomber fleets based in Britain began operations against Germany. Many sorties were intentionally given civilian targets in an effort to destroy German morale. German aircraft production could not keep pace with losses, and without air cover the Allied bombing campaign became even more devastating. By targeting oil refineries and factories, they crippled the German war effort by late 1944.
Remarkably, there were instances of individual resistance and collective efforts at fighting back inside Auschwitz. Poles, Communists and other national groups established networks in the main camp. A few Jews escaped from Birkenau, and there were recorded assaults on Nazi guards even at the entrance to the gas chambers. The 'Sonderkommando' revolt in October 1944 was the extraordinary example of physical resistance.
After our liberation I went to Sweden where we were looked after marvellously. The physical recovery was not as bad as the emotional and mental one, which I’m still working on. I am still touched by the memory of a doctor who taught me how to walk again, as through the malnutrition I was incapable. Such a simple thing, but he told me: “I have a daughter like you,” and how vital that statement of his was to my sense of becoming a human being again. It was amazing to be compared to someone having felt completely dehumanised for so long.
One evening at inspection, the camp commander gave us an address in which he said that we were responsible for the murder of Herr vom Rath and that therefore we had committed a crime against the nation and the state; that we were in a camp for protective custody, which was not a prison or a penitentiary at all, nor a sanitarium either, but solely an educational institution; that we should learn here how to behave in dealing with a 'guest nation' (he really said 'guest' nation instead of 'host' nation); that the main thing was unconditional obedience and that all S.S. men were our superior officers; that each attempt at disobedience would be punished, in some cases by corporal punishment, and that all S. S. men were entitled to use their arms in any attempt at resistance or escape.
The statements and writings of Holocaust deniers attributed great influence to Anne and her diary: as a symbol of the persecuted child, they claimed, it helped in the establishment and financing of the State of Israel; they maintained that she harmed Germans as well as Palestinians, that her diary was used as a political tool by world Jewry, and its distribution was an exemplary lesson in how to circulate propaganda throughout the world. Indirectly, their statements show tremendous admiration for the Jewish people, its ability to set up a public relations mechanism unparalleled the world over, and for Otto Frank as the gifted and successful representative of his people. Their statements also express great sorrow over the victory that the Jewish people achieved through the diary, a symbol of goodness, forgiveness and hope, and of the place it won in world culture and consciousness. Indeed, the diary, the Anne Frank House and the worldwide exhibitions became a focus for activity against racism and fascism, advocating on behalf of the individual and minorities. In the Netherlands, liberal groups work together with Jewish organizations and receive government support; by nurturing Anne’s memory, the Netherlands can find relief from the guilt feelings it has borne since the war and act against the right and its racist outlook. Thus the Jewish people and Anne Frank have become a central part of the struggle between different outlooks in government, society and legislation.
Other Nazis—especially those at the time associated with the party's more radical wing such as Gregor Strasser, Joseph Goebbels and Heinrich Himmler—rejected Italian Fascism, accusing it of being too conservative or capitalist. Alfred Rosenberg condemned Italian Fascism for being racially confused and having influences from philosemitism. Strasser criticised the policy of Führerprinzip as being created by Mussolini and considered its presence in Nazism as a foreign imported idea. Throughout the relationship between Nazi Germany and Fascist Italy, a number of lower-ranking Nazis scornfully viewed fascism as a conservative movement that lacked a full revolutionary potential.
Use of the word "concentration" came from the idea of confining people in one place because they belong to a group that is considered undesirable in some way. The term itself originated in 1897 when the "reconcentration camps" were set up in Cuba by General Valeriano Weyler. In the past, the U.S. government had used concentration camps against Native Americans and the British had also used them during the Second Boer War. Between 1904 and 1908, the Schutztruppe of the Imperial German Army operated concentration camps in German South-West Africa (now Namibia) as part of its genocide of the Herero and Namaqua peoples. The Shark Island Concentration Camp in Lüderitz was the largest camp and the one with the harshest conditions.
