The NSDAP was a far-right political party which arose during the social and financial upheavals that occurred following the end of World War I. The NSDAP remained small and marginalised, receiving 2.6% of the federal vote in 1928, prior to the onset of the Great Depression in 1929.[178] By 1930 the NSDAP won 18.3% of the federal vote, making it the Reichstag's second largest political party.[179] While in prison after the failed Beer Hall Putsch of 1923, Hitler wrote Mein Kampf, which laid out his plan for transforming German society into one based on race.[180] Nazi ideology brought together elements of antisemitism, racial hygiene, and eugenics, and combined them with pan-Germanism and territorial expansionism with the goal of obtaining more Lebensraum for the Germanic people.[181] The regime attempted to obtain this new territory by attacking Poland and the Soviet Union, intending to deport or kill the Jews and Slavs living there, who were viewed as being inferior to the Aryan master race and part of a Jewish-Bolshevik conspiracy.[182][183] The Nazi regime believed that only Germany could defeat the forces of Bolshevism and save humanity from world domination by International Jewry.[184] Other people deemed life unworthy of life by the Nazis included the mentally and physically disabled, Romani people, homosexuals, Jehovah's Witnesses, and social misfits.[185][186]
Although Nazism is often seen as a reactionary movement, it did not seek a return of Germany to the pre-Weimar monarchy, but instead looked much further back to a mythic halcyon Germany which never existed. It has also been seen – as it was by the German-American scholar Franz Leopold Neumann – as the result of a crisis of capitalism which manifested as a "totalitarian monopoly capitalism". In this view Nazism is a mass movement of the middle class which was in opposition to a mass movement of workers in socialism and its extreme form, Communism.[277] Historian Karl Dietrich Bracher, however, argues that,
In July 1942, when transports from the Westerbork transit camp to Auschwitz began, the family went into hiding together with the van Pels family and Fritz Pfeffer. The hiding place of these eight people was an attic at 263 Prisengracht Street in Amsterdam, the building that contained Otto’s business. For two years, from June 1942, when Anne received a diary for her thirteenth birthday, until she was about fifteen, Anne wrote in her diary nearly every day. Once the hiding place was discovered on August 4, 1944, the diary entries stopped.
We lived in Bótrágy, a very small, mostly poor town in Czechoslovakia with a population of approximately 1,000 mainly farming families, including about 10 Jewish families. The town was a typical low-income community with a tailor, a shoemaker, a grocery store, where people struggled to get by, but where everyone knew each other and there was easy communication between the neighbours, though that didn’t mean we were equal.
During war, civilians have been concentrated in camps to prevent them from engaging in guerrilla warfare or providing aid to enemy forces or simply as a means of terrorizing the populace into submission. During the South African War (1899–1902) the British confined noncombatants of the republics of Transvaal and Cape Colony in concentration camps. Another instance of interning noncombatant civilians occurred shortly after the outbreak of hostilities between Japan and the United States (December 7, 1941), when more than 100,000 Japanese and Japanese-Americans on the West Coast were taken into custody and placed in camps in the interior.

The National Socialist Programme was a formulation of the policies of the party. It contained 25 points and is therefore also known as the "25-point plan" or "25-point programme". It was the official party programme, with minor changes, from its proclamation as such by Hitler in 1920, when the party was still the German Workers' Party, until its dissolution.
After Anne’s diary was published, some people called it a hoax—particularly neo-Nazis who wanted to claim the Holocaust never happened. In 1963, Nazi hunter and concentration camp survivor Simon Wiesenthal tracked down former SS officer Karl Silberbauer, who at that time was working as a police inspector in Austria. When confronted, Silberbauer confessed, "Yes, I arrested Anne Frank."
The Franks realized that conditions in Germany were only going to get worse and decided to leave the country. Otto traveled to Amsterdam, the Netherlands, that summer believing that his family would be safer there than in Germany. In September he established an independent branch of Opekta Werk, which made fruit pectin for jams and jellies, and a few years later, Pectacon, which made meat spices. When Otto left for Amsterdam, Edith and the girls went to stay with Grandmother Holländer, Edith’s mother, in Aachen, Germany. In December, Edith and Margot joined Otto in Amsterdam and Anne followed in February 1934. In March 1939, Grandmother Holländer joined them also.
After a fortnight we were able to use the money which we had brought in or was sent to us, and it became possible to complete and improve our diet from the canteen at our own expense. We were lined up in rows exactly in the order of our prison numbers, which had been sewed in black on white on our clothes. (This also is penitentiary procedure, for an inmate of the penitentiary is not an individual any more, but only a numbered being without a name.) Then we were led into the barracks where an S.S. man sitting behind a sort of teller's window disbursed the desired sum, up to fifteen marks a week. Somehow I must have transgressed against the military discipline in this procedure. I presume that I had my cap in the wrong hand. Instead of the money I received a violent blow on the back of my hand with a heavy stick which was lying next to the paymaster on his table, obviously for such purposes. Many weeks after this experience the back of my hand was still painful and swollen.
A concentration camp to house Soviet prisoners of war and Poles had been established at Majdanek, close to the Polish city of Lublin, during 1941. In the spring of 1942 gas chambers and crematoria were added, turning Majdanek into an extermination camp that would murder 78,000 people. Auschwitz-Birkenau, the most infamous of the Nazi death camps, was a massive concentration, forced labour and extermination camp at the centre of a network of more than 40 satellite camps. Upwards of 80 per cent of those Jews transported to Auschwitz-Birkenau were selected for immediate death.
After less than a year at Auschwitz, Lasker-Wallfisch and Renate were among the tens of thousands of prisoners transported to camps in Germany. Lasker-Wallfisch had no idea where she was being sent, but it didn’t matter. “The gas chambers were still working when we left,” she says. “I was very pleased to be rolling out of Auschwitz. We figured anything was better than the gas chamber.” On April 15, 1945, British troops liberated Lasker-Wallfisch and Renate from the Bergen-Belsen concentration camp near Hamburg. Lasker-Wallfisch emigrated to England after the war and became a professional cellist. Her sister Renate worked for the BBC, and is now living in France.

In Autumn 1943, the camp administration was reorganized following a corruption scandal. By the end of 1943, the prisoner population of Auschwitz main camp, Birkenau, Monowitz and other sub-camps was over 80,000: 18,437 in the main camp, 49,114 in Birkenau, and 13,288 at Monowitz where I G Farben had its synthetic rubber plant. Up to 50,000 prisoners were scattered around 51 sub-camps such as Rajsko, an experimental agricultural station, and Gleiwitz, a coal mine (see The List of the Camps for a complete list of those sub-camps).

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]
