Use of bunkers I and 2 stopped in spring 1943 when the new crematoria were built, although bunker 2 became operational again in May 1944 for the murder of the Hungarian Jews.[47] Crematorium II, which had been designed as a mortuary with morgues in the basement and ground-level incinerators, was converted by installing gas-tight doors, vents for the Zyklon B to be dropped into the chamber, and ventilation equipment to remove the gas thereafter.[48] It went into operation in March 1943. Crematorium III was built using the same design. Crematoria IV and V, designed from the start as gassing centers, were also constructed that spring. By June 1943, all four crematoria were operational. Most of the victims were killed using these four structures.[49]
When Otto Frank returned to Amsterdam following his release from Auschwitz, Miep Gies gave him five notebooks and some 300 loose papers containing Anne’s writings. Gies had recovered the materials from the Secret Annex shortly after the Franks’ arrest by the Nazis and had hidden them in her desk. (Margot Frank also kept a diary, but it was never found.) Otto Frank knew that Anne wanted to become an author or journalist, and had hoped her wartime writings would one day be published. Anne had even been inspired to edit her diary for posterity after hearing a March 1944 radio broadcast from an exiled Dutch government official who urged the Dutch people to keep journals and letters that would help provide a record of what life was like under the Nazis.

Racism, especially antisemitism, was a central feature of the regime. The Germanic peoples were considered by the Nazis to be the master race, the purest branch of the Aryan race. Discrimination and persecution against Jews and Romani people began in earnest after the seizure of power. The first concentration camps were established in March 1933. Jews and others deemed undesirable were imprisoned, and liberals, socialists, and communists were killed, imprisoned, or exiled. Christian churches and citizens that opposed Hitler's rule were oppressed, and many leaders imprisoned. Education focused on racial biology, population policy, and fitness for military service. Career and educational opportunities for women were curtailed. Recreation and tourism were organised via the Strength Through Joy program, and the 1936 Summer Olympics showcased Germany on the international stage. Propaganda Minister Joseph Goebbels made effective use of film, mass rallies, and Hitler's hypnotic oratory to influence public opinion. The government controlled artistic expression, promoting specific art forms and banning or discouraging others.
Today, the word Auschwitz has become synonymous with terror, genocide, and The Holocaust. The site, though partially destroyed by the retreating Nazi’s in 1945, has been established as a museum to help future generations understand the atrocities committed within its fences. By 2011, more than 30 million people had visited the camp, and during 2014 a record number of 1.5 million people visited the Auschwitz complex and museum. Spokespeople for the museum said that from January to April 2015, over 250,000 people visited Auschwitz, marking a 40% increase over the already large numbers from the previous year. Authorities in charge of the site began to urge people to book their visit to Auschwitz online ahead of time to prevent them from having to turn people away.
Life for the eight people in the small apartment, which Anne Frank referred to as the Secret Annex, was tense. The group lived in constant fear of being discovered and could never go outside. They had to remain quiet during daytime in order to avoid detection by the people working in the warehouse below. Anne passed the time, in part, by chronicling her observations and feelings in a diary she had received for her 13th birthday, a month before her family went into hiding.
Our daily occupation differed according to age. Prisoners below the forty-fifth year were used for especially hard labor outside the camp in the 'clinker works.' Heavy bags of cement had to be carried for long distances, and the return to the starting point had to be covered at a running pace. For a while the older prisoners were also used outside the camp working on an S.S. settlement. They had to dig or carry cement blocks. All this work was done under the supervision of young S.S. men, most of whom were boys of sixteen to twenty years from former Austria. They circled around us armed with loaded guns or light machine guns. They drove us on and misused their position of superiority with all sorts of torments. If presumably a little offense had been committed, especially if our speed of work didn't satisfy them, they might demand that the prisoner should do knee-bends until he was exhausted or that he roll down the slope a dozen times. In our camp were prisoners ranging in age from fourteen to eighty-four.
…party, Hitler joined a German nationalist group that took the name of National Socialist German Workers’ Party (Nationalsozialistische Deutsche Arbeiterpartei), nicknamed “Nazi,” a truncation of Nationalsozialistische. Its policies included anti-Semitism and fierce opposition to the Treaty of Versailles. After his abortive Munich coup in 1923, Hitler was sentenced to five…

This is not the limit of the horrors of Auschwitz I. It was also the site of disturbing medical experimentation on Jewish and Roma prisoners, including castration, sterilisation and testing how they were affected by contagious diseases. The infamous “Angel of Death”, SS captain Dr Josef Mengele, was one of the physicians practising here. His particular interest was experimenting on twins.

Drexler's movement received attention and support from some influential figures. Supporter Dietrich Eckart, a well-to-do journalist, brought military figure Felix Graf von Bothmer, a prominent supporter of the concept of "national socialism", to address the movement.[27] Later in 1918, Karl Harrer (a journalist and member of the Thule Society) convinced Drexler and several others to form the Politischer Arbeiterzirkel (Political Workers' Circle).[23] The members met periodically for discussions with themes of nationalism and racism directed against the Jews.[23] In December 1918, Drexler decided that a new political party should be formed, based on the political principles that he endorsed, by combining his branch of the Workers' Committee for a good Peace with the Political Workers' Circle.[23][28]
The destruction of valuable property, of irretrievable art treasures, as well as of valuable tapestries in Munich, of Rembrandt pictures in Hesse, was not enough. The decision was made to bring a great number of Jews into camps for protective custody. Rough estimate places the number of victims at about sixty thousand males. In the camp with which we are dealing there were probably about six to seven thousand men.
Germany regained control of the Saarland through a referendum held in 1935 and annexed Austria in the Anschluss of 1938.[164] The Munich Agreement of 1938 gave Germany control of the Sudetenland, and they seized the remainder of Czechoslovakia six months later.[70] Under threat of invasion by sea, Lithuania surrendered the Memel district in March 1939.[165]
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.[62] 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.[91] 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".[91]
The complex, which divided into three main areas, was established by the Nazi’s in 1940 and was in use until its Allied liberation in 1945. Historians and analysts estimate the number of people murdered at Auschwitz somewhere between 2.1 million to 4 million, of whom the vast majority were Jews. The majority of prisoners held at Auschwitz were killed in the various gas chambers though many died from starvation, forced labor, disease, shooting squads, and heinous medical experiments.
The commander of Auschwitz-Birkenau, Rudolf Höss, stated in his autobiography that in 1941 (no exact date is given) he was summoned to Berlin, where Himmler informed him that Hitler had issued an order to solve the “Jewish Question” for good, and that the order was to be implemented by the SS. “The existing extermination places in the east are unsuited to a large scale, long-term action. I have designated Auschwitz for this purpose,” Himmler said.

After 1942, many small subcamps were set up near factories to provide forced labor. IG Farben established a synthetic rubber plant in 1942 at Monowitz concentration camp (Auschwitz III); other camps were set up next to airplane factories, coal mines and rocket propellant plants. Conditions were brutal and prisoners were often sent to the gas chambers or killed on site if they did not work quickly enough.
