On the night of the 27 February 1933 and 28 February 1933, someone set the Reichstag building on fire. This was the building where the German Parliament held their meetings. The Nazis blamed the communists. Opponents of the Nazis said that the Nazis themselves had done it to come to power. On the very same day, an emergency law called Reichstagsbrandverordnung was passed. The government claimed it was to protect the state from people trying to hurt the country. With this law, most of the civil rights of the Weimar Republic did not count any longer. The Nazis used this against the other political parties. Members of the communist and social-democratic parties were put into prison or killed.
A concentration camp was not the same as an extermination camp – camps constructed with the specific purpose of mass murdering Jews and other victim groups. Despite this fact, the concentration camps claimed many thousands of victims. Imprisonment in a concentration camp meant inhuman forced labour, brutal mistreatment, hunger, disease, and random executions. It is certain that several hundred thousand died in the concentration camps. In comparison, more than three million Jews were murdered in the extermination camps.

Despite the spirit of freezing the site in time, some exhibits have been redesigned in recent years — the Russian Federation’s tells the story of Russian political prisoners here; those of the Netherlands and France and Belgium talk about the fate of their Jews; the exhibit dedicated to the Sinti and Roma present the often-neglected story of those peoples murdered here. The Polish exhibit is colored by the country’s Communist past.

According to Polish historian Andrzej Strzelecki, the evacuation of the prisoners by the SS in January 1945 was one of the camp's "most tragic chapters".[235] In mid-1944, about 130,000 prisoners were in Auschwitz when the SS moved around half of them to other concentration camps.[236] In November 1944, with the Soviet Red Army approaching through Poland, Himmler ordered gassing operations to cease. The crematorium IV building was dismantled,[237] and the Sonderkommando was ordered to remove evidence of the killings, including the mass graves.[238] The SS destroyed written records, and in the final week before the camp's liberation, burned or demolished many of its buildings.[239] The plundered goods from the "Canada" barracks at Birkenau, together with building supplies, were transported to the German interior. On 20 January, the overflowing warehouses were set ablaze. Crematoria II and III at Birkenau were blown up on 20 January and crematorium V six days later, just one day ahead of the Soviet attack.[237]
Antisemitic legislation passed in 1933 led to the removal of all Jewish teachers, professors, and officials from the education system. Most teachers were required to belong to the Nationalsozialistischer Lehrerbund (NSLB; National Socialist Teachers League) and university professors were required to join the National Socialist German Lecturers.[349][350] Teachers had to take an oath of loyalty and obedience to Hitler, and those who failed to show sufficient conformity to party ideals were often reported by students or fellow teachers and dismissed.[351][352] Lack of funding for salaries led to many teachers leaving the profession. The average class size increased from 37 in 1927 to 43 in 1938 due to the resulting teacher shortage.[353]
Early in the Nazi regime of Adolf Hitler, Anne’s father, Otto Frank (1889–1980), a German businessman, took his wife and two daughters to live in Amsterdam. In 1941, after German forces occupied the Netherlands, Anne was compelled to transfer from a public school to a Jewish one. On June 12, 1942, she received a red-and-white plaid diary for her 13th birthday. That day she began writing in the book: “I hope I will be able to confide everything to you, as I have never been able to confide in anyone, and I hope you will be a great source of comfort and support.”
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.
Most of the teenage boys and girls in the photo are hamming it up for the camera, celebrating as nearly all raise as their right hand to deliver what looks like the Nazi salute. A few can be seen holding their phones and at least one girl appears to be taking a picture of the swastika made up of about 100 red plastic cups that look as though they've been set up to play a white supremacist version of the popular drinking game, beer pong.

Heinrich Himmler's Schutzstaffel (SS) took full control of the police and the concentration camps throughout Germany in 1934–35.[5] Himmler expanded the role of the camps to hold so-called "racially undesirable elements", such as Jews, Gypsies/Romanis/Sintis, Serbs, Poles, disabled people, and criminals.[6][7][8] The number of people in the camps, which had fallen to 7,500, grew again to 21,000 by the start of World War II[9] and peaked at 715,000 in January 1945.[10]
