The property is of adequate size to ensure the complete representation of the features and processes that convey its significance. Potential threats to the integrity of the property include the difficulty in preserving the memory of the events and their significance to humanity. In the physical sphere, significant potential threats include natural decay of the former camps’ fabric; environmental factors, including the risk of flooding and rising groundwater level; changes in the surroundings of the former camps; and intensive visitor traffic.

Movies were popular in Germany in the 1930s and 1940s, with admissions of over a billion people in 1942, 1943 and 1944.[478][479] By 1934, German regulations restricting currency exports made it impossible for US film makers to take their profits back to America, so the major film studios closed their German branches. Exports of German films plummeted, as their antisemitic content made them impossible to show in other countries. The two largest film companies, Universum Film AG and Tobis, were purchased by the Propaganda Ministry, which by 1939 was producing most German films. The productions were not always overtly propagandistic, but generally had a political subtext and followed party lines regarding themes and content. Scripts were pre-censored.[480]
In 1938, Otto Frank started a second company, Pectacon, which was a wholesaler of herbs, pickling salts, and mixed spices, used in the production of sausages.[11][12] Hermann van Pels was employed by Pectacon as an advisor about spices. A Jewish butcher, he had fled Osnabrück with his family.[12] In 1939, Edith Frank's mother came to live with the Franks, and remained with them until her death in January 1942.[13]
Following the June 1941 German invasion of the Soviet Union, the Nazis increased the number of prisoner-of-war (POW) camps. Some new camps were built at existing concentration camp complexes (such as Auschwitz) in occupied Poland. The camp at Lublin, later known as Majdanek, was established in the autumn of 1941 as a POW camp and became a concentration camp in 1943. Thousands of Soviet POWs were shot or gassed there.

With the other women and girls not selected for immediate death, Frank was forced to strip naked to be disinfected, had her head shaved, and was tattooed with an identifying number on her arm. By day, the women were used as slave labour and Frank was forced to haul rocks and dig rolls of sod; by night, they were crammed into overcrowded barracks. Some witnesses later testified Frank became withdrawn and tearful when she saw children being led to the gas chambers; others reported that more often she displayed strength and courage. Her gregarious and confident nature allowed her to obtain extra bread rations for her mother, sister, and herself. Disease was rampant; before long, Frank's skin became badly infected by scabies. The Frank sisters were moved into an infirmary, which was in a state of constant darkness and infested with rats and mice. Edith Frank stopped eating, saving every morsel of food for her daughters and passing her rations to them through a hole she made at the bottom of the infirmary wall.[53]

The Polish government-in-exile in London first reported the gassing of prisoners in Auschwitz on 21 July 1942,[210] and reported the gassing of Soviet POWs and Jews on 4 September 1942.[211] In 1943, the Kampfgruppe Auschwitz (Combat Group Auschwitz) was organized within the camp with the aim of sending out information about what was happening.[212] Sonderkommandos buried notes in the ground, hoping they would be found by the camp's liberators.[213] The group also smuggled out photographs; the Sonderkommando photographs, of events around the gas chambers in Auschwitz II, were smuggled out of the camp in September 1944 in a toothpaste tube.[214] According to Fleming, the British press responded, in 1943 and the first half of 1944, either by not publishing reports about Auschwitz or by burying them on the inside pages. The exception was the Polish Jewish Observer, published as a supplement to the City and East London Observer and edited by Joel Cang, a former Warsaw correspondent for the Manchester Guardian. The British reticence stemmed from a Foreign Office concern that the public might pressure the government to respond or provide refuge for the Jews, and that British actions on behalf of the Jews might affect its relationships in the Middle East. There was similar reticence in the United States, and indeed within the Polish government-in-exile and the Polish resistance. According to Fleming, the scholarship suggests that the Polish resistance distributed information about the Holocaust in Auschwitz without challenging the Allies' reluctance to highlight it.[215]
A separate camp for the Roma, the Zigeunerfamilienlager ("Gypsy family camp"), was set up in the BIIe sector of Auschwitz II-Birkenau in February 1943. For unknown reasons, they were not subject to selection and families were allowed to stay together. The first transport of German Roma arrived at Auschwitz II on 26 February that year. There had been a small number of Romani inmates before that; two Czech Romani prisoners, Ignatz and Frank Denhel, tried to escape in December 1942, the latter successfully, and a Polish Romani woman, Stefania Ciuron, arrived on 12 February 1943 and escaped in April.[145]
After the outbreak of war, people from across Europe were deported to Mauthausen, which gradually developed into a system of several interconnected camps. During this phase, Mauthausen and Gusen were the concentration camps with the harshest imprisonment conditions and the highest mortality. Prisoners at the bottom of the camp hierarchy had barely any chance of surviving for long. Those who were ill or ‘useless’ to the SS were in constant danger of their lives. In 1941 the SS started to construct a gas chamber and other installations at Mauthausen for the systematic murder of large groups of people.
In 2016, the Anne Frank House published new research pointing to investigation over ration card fraud, rather than betrayal, as a plausible explanation for the raid that led to the arrest of the Franks.[46] The report states that other activities in the building may have led authorities there, including activities of Frank's company. However, it does not rule out betrayal.[47]

Women were expected to be strong, healthy, and vital.[378] The sturdy peasant woman who worked the land and bore strong children was considered ideal, and women were praised for being athletic and tanned from working outdoors.[379] Organisations were created for the indoctrination of Nazi values. From 25 March 1939 membership in the Hitler Youth was made compulsory for all children over the age of ten.[380] The Jungmädelbund (Young Girls League) section of the Hitler Youth was for girls age 10 to 14 and the Bund Deutscher Mädel (BDM; League of German Girls) was for young women age 14 to 18. The BDM's activities focused on physical education, with activities such as running, long jumping, somersaulting, tightrope walking, marching, and swimming.[381]
All of their clothes and any remaining personal belongings were taken from them and their hair was shorn completely off. They were given striped prison outfits and a pair of shoes, all of which were usually the wrong size. They were then registered, had their arms tattooed with a number, and transferred to one of Auschwitz's camps for forced labor.
The orders for the final evacuation and liquidation of the camp were issued in mid-January 1945. The Germans left behind in the main Auschwitz camp, Birkenau and in Monowitz about 7,000 sick or incapacitated who they did not expect would live for long; the rest, approximately 58,000 people, were evacuated by foot into the depths of the Third Reich.
Leni Riefenstahl's Triumph of the Will (1935)—documenting the 1934 Nuremberg Rally—and Olympia (1938)—covering the 1936 Summer Olympics—pioneered techniques of camera movement and editing that influenced later films. New techniques such as telephoto lenses and cameras mounted on tracks were employed. Both films remain controversial, as their aesthetic merit is inseparable from their propagandising of National Socialist ideals.[481][482]
Since the Nazis extended the Rassenschande ("race defilement") law to all foreigners at the beginning of the war,[139] pamphlets were issued to German women which ordered them to avoid sexual relations with foreign workers who were brought to Germany and the pamphlets also ordered German women to view these same foreign workers as a danger to their blood.[190] Although the law was applicable to both genders, German women were punished more severely for having sexual relations with foreign forced labourers in Germany.[191] The Nazis issued the Polish decrees on 8 March 1940 which contained regulations concerning the Polish forced labourers (Zivilarbeiter) who were brought to Germany during World War II. One of the regulations stated that any Pole "who has sexual relations with a German man or woman, or approaches them in any other improper manner, will be punished by death".[192]
After Nazi Germany unleashed World War II in September 1939, vast new territorial conquests and larger groups of potential prisoners led to the rapid expansion of the concentration camp system to the east. The war did not change the original function of the concentration camps as detention sites for the incarceration of political enemies. The climate of national emergency that the conflict granted to the Nazi leaders, however, permitted the SS to expand the functions of the camps.

This debacle did not discourage Himmler and Pohl. On the contrary, with the coming of war, in 1939, S.S. ambitions for the camps grew rapidly, along with their prisoner population. On the eve of the war, the entire K.L. system contained only about twenty-one thousand prisoners; three years later, the number had grown to a hundred and ten thousand, and by January, 1945, it was more than seven hundred thousand. New camps were built to accommodate the influx of prisoners from conquered countries and then the tens of thousands of Red Army soldiers taken prisoner in the first months after Operation Barbarossa, the German invasion of the U.S.S.R.
I was taken into protective custody in connection with the murder of the German attaché in Paris, Ernst vom Rath, by the seventeen-year-old Polish subject, Grynszpan, who had been expelled from Germany first and then had been ordered to leave France. I do not want to justify this political murder in any way, but I can understand it as the act of a hopelessly desperate person.
Stos said he survived by making himself useful. Prisoners had a better chance of staying alive if they worked under a roof—in a kitchen or an administration building—or had a skill, such as training in medicine or engineering, that made them hard to replace. “The hunger was hellish, and if you could work you could get something to eat,” Stos said. Having grown up in the countryside, he could do a little bit of everything, from pouring concrete to cutting grass. I pressed him for details of his time in the camp, but he spoke only of the work. “I had eight different professions at Auschwitz,” he said. “I knew how to take care of myself. I avoided the worst of it.”
Many of the prisoners died in the concentration camps due to deliberate maltreatment, disease, starvation, and overwork, or they were executed as unfit for labor. Prisoners were transported in inhumane conditions by rail freight cars, in which many died before reaching their final destination. The prisoners were confined in the boxcars for days or even weeks, with little or no food or water. Many died of dehydration in the intense heat of summer or froze to death in winter. Concentration camps also existed in Germany itself, and while they were not specifically designed for systematic extermination, many of their inmates perished because of harsh conditions or they were executed.
