Persecution of the Catholic Church in Germany followed the Nazi takeover.[417] Hitler moved quickly to eliminate political Catholicism, rounding up functionaries of the Catholic-aligned Bavarian People's Party and Catholic Centre Party, which along with all other non-Nazi political parties ceased to exist by July.[418] The Reichskonkordat (Reich Concordat) treaty with the Vatican was signed in 1933, amid continuing harassment of the church in Germany.[314] The treaty required the regime to honour the independence of Catholic institutions and prohibited clergy from involvement in politics.[419] Hitler routinely disregarded the Concordat, closing all Catholic institutions whose functions were not strictly religious.[420] Clergy, nuns and lay leaders were targeted, with thousands of arrests over the ensuing years, often on trumped-up charges of currency smuggling or immorality.[421] Several Catholic leaders were targeted in the 1934 Night of the Long Knives assassinations.[422][423][424] Most Catholic youth groups refused to dissolve themselves and Hitler Youth leader Baldur von Schirach encouraged members to attack Catholic boys in the streets.[425] Propaganda campaigns claimed the church was corrupt, restrictions were placed on public meetings and Catholic publications faced censorship. Catholic schools were required to reduce religious instruction and crucifixes were removed from state buildings.[426]
Concentration camp, internment centre for political prisoners and members of national or minority groups who are confined for reasons of state security, exploitation, or punishment, usually by executive decree or military order. Persons are placed in such camps often on the basis of identification with a particular ethnic or political group rather than as individuals and without benefit either of indictment or fair trial. Concentration camps are to be distinguished from prisons interning persons lawfully convicted of civil crimes and from prisoner-of-war camps in which captured military personnel are held under the laws of war. They are also to be distinguished from refugee camps or detention and relocation centres for the temporary accommodation of large numbers of displaced persons.
Annelies Marie Frank was born in Frankfurt on June 12, 1929 to Edith (née Holländer) and Otto Frank. The Frank family, which was affluent and socially active, had lived in the city since the seventeenth century. Otto and his two brothers served in the German army in World War I. In 1933, after the Nazi party came to power, the family moved to Amsterdam. For the first seven years, things were relatively quiet for the parents and their two daughters, Margot Betti (1926–1945) and her younger sister Anne, who attended the Montessori school until Germany invaded the Netherlands in May 1940.
Adolf Hitler, the party's leader since 1921, was appointed Chancellor of Germany by President Paul von Hindenburg on 30 January 1933. Hitler rapidly established a totalitarian regime[12][13][14][15] known as the Third Reich. Following the defeat of the Third Reich at the conclusion of World War II in Europe, the party was "declared to be illegal" by the Allied powers,[16] who carried out denazification in the years after the war.

Following Nazi Germany's defeat in World War II and the end of the Holocaust, overt expressions of support for Nazi ideas were prohibited in Germany and other European countries. Nonetheless, movements which self-identify as National Socialist or which are described as adhering to National Socialism continue to exist on the fringes of politics in many western societies. Usually espousing a white supremacist ideology, many deliberately adopt the symbols of Nazi Germany.[288]

The most infamous doctor at Auschwitz was Josef Mengele, the "Angel of Death", who worked in Auschwitz II from 30 May 1943, at first in the gypsy family camp.[127] Particularly interested in performing research on identical twins, dwarfs, and those with hereditary disease, Mengele set up a kindergarten in barracks 29 and 31 for children he was experimenting on, and for all Romani children under six, where they were given better food rations.[128] From May 1944, he would select twins and dwarfs during selection on the Judenrampe,[129] reportedly calling for twins with "Zwillinge heraus!" ("twins step forward!").[130] He and other doctors (the latter prisoners) would measure the twins' body parts, photograph them, and subject them to dental, sight and hearing tests, x-rays, blood tests, surgery, and blood transfusions between them.[131] Then he would have them killed and dissected.[129] Kurt Heissmeyer, another German doctor and SS officer, took 20 Jewish children from Auschwitz to use in pseudoscientific medical experiments at the Neuengamme concentration camp.[132] In April 1945, the children were killed by hanging to conceal the project.[133]
In January 1923, France occupied the Ruhr industrial region as a result of Germany's failure to meet its reparations payments. This led to economic chaos, the resignation of Wilhelm Cuno's government and an attempt by the German Communist Party (KPD) to stage a revolution. The reaction to these events was an upsurge of nationalist sentiment. Nazi Party membership grew sharply to about 20,000.[65] By November, Hitler had decided that the time was right for an attempt to seize power in Munich, in the hope that the Reichswehr (the post-war German military) would mutiny against the Berlin government and join his revolt. In this, he was influenced by former General Erich Ludendorff, who had become a supporter—though not a member—of the Nazis.
Hitler ruled Germany autocratically by asserting the Führerprinzip ("leader principle"), which called for absolute obedience of all subordinates. He viewed the government structure as a pyramid, with himself—the infallible leader—at the apex. Party rank was not determined by elections, and positions were filled through appointment by those of higher rank.[190] The party used propaganda to develop a cult of personality around Hitler.[191] Historians such as Kershaw emphasise the psychological impact of Hitler's skill as an orator.[192] Roger Gill states: "His moving speeches captured the minds and hearts of a vast number of the German people: he virtually hypnotized his audiences".[193]
In the early years of the regime, Germany was without allies, and its military was drastically weakened by the Versailles Treaty. France, Poland, Italy, and the Soviet Union each had reasons to object to Hitler's rise to power. Poland suggested to France that the two nations engage in a preventive war against Germany in March 1933. Fascist Italy objected to German claims in the Balkans and on Austria, which Benito Mussolini considered to be in Italy's sphere of influence.[52]
After what happened, and having lost 50 members of my family, it was very important for me to have my own little family, to have again that sense of belonging. I really wanted to have children and was just 18 when I got married to a fellow Holocaust survivor from Transylvania. But I’ve always been careful not to tell my children too much about what I went through so as not to traumatise them. They’re entitled to a carefree youth, I always thought, and I didn’t want to be spreading bitterness and hate.

^ Hitler stated: "Today our left-wing politicians in particular are constantly insisting that their craven-hearted and obsequious foreign policy necessarily results from the disarmament of Germany, whereas the truth is that this is the policy of traitors […] But the politicians of the Right deserve exactly the same reproach. It was through their miserable cowardice that those ruffians of Jews who came into power in 1918 were able to rob the nation of its arms." Adolf Hitler. Mein Kampf. Bottom of the Hill Publishing, 2010. p. 287.
The Parteiflagge design, with the centred swastika disc, served as the party flag from 1920. Between 1933 (when the Nazi Party came to power) and 1935, it was used as the National flag (Nationalflagge) and Merchant flag (Handelsflagge), but interchangeably with the black-white-red horizontal tricolour. In 1935, the black-white-red horizontal tricolour was scrapped (again) and the flag with the off-centre swastika and disc was instituted as the national flag, and remained as such until 1945. The flag with the centred disk continued to be used after 1935, but exclusively as the Parteiflagge, the flag of the party.

Nazism, also spelled Naziism, in full National Socialism, German Nationalsozialismus, totalitarian movement led by Adolf Hitler as head of the Nazi Party in Germany. In its intense nationalism, mass appeal, and dictatorial rule, Nazism shared many elements with Italian fascism. However, Nazism was far more extreme both in its ideas and in its practice. In almost every respect it was an anti-intellectual and atheoretical movement, emphasizing the will of the charismatic dictator as the sole source of inspiration of a people and a nation, as well as a vision of annihilation of all enemies of the Aryan Volk as the one and only goal of Nazi policy.
In 1963, Otto Frank and his second wife, Elfriede Geiringer-Markovits, set up the Anne Frank Fonds as a charitable foundation, based in Basel, Switzerland. The Fonds raises money to donate to causes "as it sees fit". Upon his death, Otto willed the diary's copyright to the Fonds, on the provision that the first 80,000 Swiss francs in income each year was to be distributed to his heirs. Any income above this figure is to be retained by the Fonds for use on whatever projects its administrators considered worthy. It provides funding for the medical treatment of the Righteous Among the Nations on a yearly basis. The Fonds aims to educate young people against racism, and loaned some of Anne Frank's papers to the United States Holocaust Memorial Museum in Washington for an exhibition in 2003. Its annual report that year outlined its efforts to contribute on a global level, with support for projects in Germany, Israel, India, Switzerland, the United Kingdom, and the United States.[105]
Hitler added to Pan-Germanic aspirations the almost mystical fanaticism of a faith in the mission of the German race and the fervour of a social revolutionary gospel. This gospel was most fully expressed in Hitler’s personal testament Mein Kampf (1925–27; “My Struggle”), in which he outlined both his practical aims and his theories of race and propaganda.
The twin pairs of gas chambers were numbered II and III, and IV and V. The first opened on March 31, 1943, the last on April 4, 1943. The total area of the gas chambers was 2,255 square meters; the capacity of these crematoria was 4,420 people. Those selected to die were undressed in the undressing room and then pushed into the gas chambers. It took about 20 minutes for all the people to death. In II and III, the killings took place in underground rooms, and the corpses were carried to the five ovens by an electrically operated lift. Before cremation gold teeth and any other valuables, such as rings, were removed from the corpses. In IV and V the gas chambers and ovens were on the same level, but the ovens were so poorly built and the usage was so great that they repeatedly malfunctioned and had to be abandoned. The corpses were finally burned outside, in the open, as in 1943. Jewish sonderkommandos worked the crematoria under SS supervision.

Some prisoners—usually Aryan—were assigned positions of authority, such as Blockschreiber ("block clerk"), Funktionshäftling ("functionary"), Kapo ("head" or "overseer"), and Stubendienst ("barracks orderly"). They were considered members of the camp elite, and had better food and lodgings than the other prisoners. The Kapos in particular wielded tremendous power over other prisoners, whom they often abused.[88][89] Very few Kapos were prosecuted after the war, because of the difficulty in determining which Kapo atrocities had been performed under SS orders and which had been individual actions.[90]

After the liquidation of the Polish state and its institutions, the fundamental goal of German policy in occupied Poland was the exploitation of material and labor resources, and the removal of the local Polish population and ethnic minorities. This was done through expulsion and systematic extermination. The Polish lands were to be completely germanized, through German settlement in the depopulated area.

On 5 January 1919, Drexler created a new political party and proposed it should be named the "German Socialist Workers' Party", but Harrer objected to the term "socialist"; so the term was removed and the party was named the German Workers' Party (Deutsche Arbeiterpartei, DAP).[29] To ease concerns among potential middle-class supporters, Drexler made clear that unlike Marxists the party supported the middle-class and that its socialist policy was meant to give social welfare to German citizens deemed part of the Aryan race.[25] They became one of many völkisch movements that existed in Germany. Like other völkisch groups, the DAP advocated the belief that through profit-sharing instead of socialisation Germany should become a unified "people's community" (Volksgemeinschaft) rather than a society divided along class and party lines.[30] This ideology was explicitly antisemitic. As early as 1920, the party was raising money by selling a tobacco called Anti-Semit.[31]
A young Jewish girl named Anne Frank (1929-1945), her parents and older sister moved to the Netherlands from Germany after Adolf Hilter and the Nazis came to power there in 1933 and made life increasingly difficult for Jews. In 1942, Frank and her family went into hiding in a secret apartment behind her father’s business in German-occupied Amsterdam. The Franks were discovered in 1944 and sent to concentration camps; only Anne’s father survived. Anne Frank’s diary of her family’s time in hiding, first published in 1947, has been translated into almost 70 languages and is one of the most widely read accounts of the Holocaust.

Frank soon found the traction to publish Margot, a novel that imagined her sister living the life she once dreamed of, as a midwife in the Galilee. A surreal work that breaks the boundaries between novel and memoir, and leaves ambiguous which of its characters are dead or alive, Margot became wildly popular in Israel. Its English translation allowed Frank to find a small but appreciative audience in the United States.
The eight residents of the secret annex were transported to Auschwitz on the last train leaving the transit camp Westerbork. After a month at Auschwitz, Anne and her sister Margot were transported to Bergen-Belsen concentration camp, where thousands of people died everyday from hunger and sickness. Margot and Anne both contracted typhus and died within a short time of each other in March 1945, only a few weeks before the liberation.
In early November 1944, Anne was put on transport again. Together with her sister, she was deported to the Bergen-Belsen concentration camp. Her parents stayed behind in Auschwitz. The conditions in Bergen-Belsen were horrible, too, there was a lack of food, it was cold, and Anne, like her sister, contracted typhus. In February 1945 they both died owing to its effects, Margot first, Anne shortly afterwards. 
None of the categories are independent - one could classify many camps as a mixture of several of the above. All camps had some of the elements of an extermination camp, but systematic extermination of new arrivals by gas chambers only occurred in specialized camps. These were extermination camps, where all new-arrivals were simply killed—the "Aktion Reinhard" camps (Treblinka, Sobibór and Belzec), together with Chelmno. Two others ( Auschwitz and Majdanek) operated as combined concentration- and extermination-camps. Others like Maly Trostenets were at times classified[by whom?] as "minor extermination camps".[50]
