A concentration camp is a place where people are detained or confined without trial. Prisoners were kept in extremely harsh conditions and without any rights. In Nazi Germany after 1933, and across Nazi controlled Europe between 1938 and 1945, concentration camps became a major way in which the Nazis imposed their control. The first concentration camps in Germany were set up as detention centres to stop any opposition to the Nazis by so called ‘enemies of the state’. These people included communists, socialists, Jehovah’s Witnesses, homosexuals, Roma, and so called ‘asocials’.
After their arrest, the Franks, Van Pels and Fritz Pfeffer were sent by the Gestapo to Westerbork, a holding camp in the northern Netherlands. From there, in September 1944, the group was transported by freight train to the Auschwitz-Birkenau extermination and concentration camp complex in German-occupied Poland. Anne and Margot Frank were spared immediate death in the Auschwitz gas chambers and instead were sent to Bergen-Belsen, a concentration camp in northern Germany. In March 1945, the Frank sisters died of typhus at Bergen-Belsen; their bodies were thrown into a mass grave. Several weeks later, on April 15, 1945, British forces liberated the camp.
The Auschwitz concentration camp (Konzentrationslager Auschwitz) was a complex of over 40 concentration and extermination camps built and operated by Nazi Germany in occupied Poland during World War II and the Holocaust. It consisted of Auschwitz I, the main camp (Stammlager) and administrative headquarters, in Oświęcim; Auschwitz II–Birkenau, a combined concentration/extermination camp three kilometers away in Brzezinka; Auschwitz III–Monowitz, a labor camp seven kilometers from Auschwitz I, set up to staff an IG Farben synthetic-rubber factory; and dozens of other subcamps.[2]

By the fall of 1933, Otto Frank moved to Amsterdam, where he established a small but successful company that produced a gelling substance used to make jam. After staying behind in Germany with her grandmother in the city of Aachen, Anne joined her parents and sister Margot (1926-45) in the Dutch capital in February 1934. In 1935, Anne started school in Amsterdam and earned a reputation as an energetic, popular girl.

At universities, appointments to top posts were the subject of power struggles between the education ministry, the university boards, and the National Socialist German Students' League.[361] In spite of pressure from the League and various government ministries, most university professors did not make changes to their lectures or syllabus during the Nazi period.[362] This was especially true of universities located in predominantly Catholic regions.[363] Enrolment at German universities declined from 104,000 students in 1931 to 41,000 in 1939, but enrolment in medical schools rose sharply as Jewish doctors had been forced to leave the profession, so medical graduates had good job prospects.[364] From 1934, university students were required to attend frequent and time-consuming military training sessions run by the SA.[365] First-year students also had to serve six months in a labour camp for the Reich Labour Service; an additional ten weeks service were required of second-year students.[366]
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.
The Sturmabteilung (SA) and the Schutzstaffel (SS) functioned as the paramilitary organizations of the Nazi Party. Using the SS for the task, Hitler purged the party's more socially and economically radical factions in the mid-1934 Night of the Long Knives, including the leadership of the SA. After the death of President Hindenburg, political power was concentrated in Hitler's hands and he became Germany's head of state as well as the head of the government, with the title of Führer, meaning "leader". From that point, Hitler was effectively the dictator of Nazi Germany, which was also known as the "Third Reich", under which Jews, political opponents and other "undesirable" elements were marginalized, imprisoned or murdered. Many millions of people were eventually exterminated in a genocide which became known as the Holocaust during World War II, including around two-thirds of the Jewish population of Europe.
The Nazi Party won the greatest share of the popular vote in the two Reichstag general elections of 1932, making them the largest party in the legislature by far, but still short of an outright majority. Because none of the parties were willing or able to put together a coalition government, in 1933 Hitler was appointed Chancellor of Germany by President Paul Von Hindenburg, through the support and connivance of traditional conservative nationalists who believed that they could control him and his party. Through the use of emergency presidential decrees by Hindenburg, and a change in the Weimar Constitution which allowed the Cabinet to rule by direct decree, bypassing both Hindenburg and the Reichstag, the Nazis had soon established a one-party state.
The women selected from this transport, including Anne, Edith, and Margot, were marked with numbers between A-25060 and A-25271. Records indicating their exact numbers have not been preserved. Approximately eight weeks later, in late October 1944, Anne and Margot were transferred from Auschwitz-Birkenau to Bergen-Belsen, where they both died sometime in March 1945. Though Anne’s death certificate documents her movement between camps, it, too, does not include her tattoo ID number.
Drancy held 5,000 prisoners. Around 70,000 mainly Jewish prisoners passed through the camp between August 1941 and August 1944. On 22 June 1942, the Nazis began systematic deportations of Jews from Drancy to the extermination camps in occupied Poland. In the first transport 1,000 Jews were sent to Auschwitz-Birkenau. By the last transport on 31 July 1944, 64,759 Jews had been deported from Drancy in 64 transports. Approximately 61,000 of these Jews were sent to Auschwitz-Birkenau. A further 3,753 Jews had been transported to Sobibor.

Working from these principles, Hitler carried his party from its inauspicious beginnings in a beer cellar in Munich to a dominant position in world politics 20 years later. The Nazi Party originated in 1919 and was led by Hitler from 1920. Through both successful electioneering and intimidation, the party came to power in Germany in 1933 and governed through totalitarian methods until 1945, when Hitler committed suicide and Germany was defeated and occupied by the Allies at the close of World War II.
With the deportations from Hungary, the role of Auschwitz-Birkenau in the German plan to murder the Jews of Europe achieved its highest effectiveness. Between late April and early July 1944, approximately 440,000 Jews were deported from Hungary. Of the nearly 426,000 Hungarian Jews deported to Auschwitz, approximately 320,000 of them were sent directly to the gas chambers in Auschwitz-Birkenau. They deployed approximately 110,000 at forced labor in the Auschwitz camp complex. The SS authorities transferred many of these Hungarian Jewish forced laborers within weeks of their arrival in Auschwitz to other concentration camps in Germany and Austria.
In March 1941, Himmler ordered a second, larger complex to be built next to the original camp. It was called Auschwitz II - Birkenau. The camp at Birkenau was divided into subsections surrounded by electric fences with barbed wire. During 1943 and 1944 the BIIb section became the location of the „Terezín family camp“. At its summit, Birkenau had over 100 000 inmates. In March 1942, the Auschwitz III camp was set up at nearby Monowitz, also known as Buna Monowitz. German company I.G. Farben set up a synthetic rubber factory there, in which it used the prisoners' slave labour. Auschwitz also had a further 45 auxiliary camps, where prisoners were forced to engage in slave labour, mostly for German companies.
Uniquely at Auschwitz, prisoners were tattooed with a serial number, on their left breast for Soviet prisoners of war[97] and on the left arm for civilians.[98] Categories of prisoner were distinguishable by triangular pieces of cloth (German: Winkel) sewn onto on their jackets below their prisoner number. Political prisoners (Schutzhäftlinge or Sch), mostly Poles, had a red triangle, while criminals (Berufsverbrecher or BV) were mostly German and wore green. Asocial prisoners (Asoziale or Aso), which included vagrants, prostitutes and the Roma, wore black. Purple was for Jehovah's Witnesses (Internationale Bibelforscher-Vereinigung or IBV)'s and pink for gay men, who were mostly German.[99] An estimated 5,000–15,000 gay men prosecuted under German Penal Code Section 175 (proscribing sexual acts between men) were detained in concentration camps, of which an unknown number were sent to Auschwitz.[100] Jews wore a yellow badge, the shape of the Star of David, overlaid by a second triangle if they also belonged to a second category. The nationality of the inmate was indicated by a letter stitched onto the cloth. A racial hierarchy existed, with German prisoners at the top. Next were non-Jewish prisoners from other countries. Jewish prisoners were at the bottom.[101]
Many of the forced labour camps were satellite camps or sections of concentration camps. Auschwitz, in Poland, had over 40 such satellite camps. Inmates of the labour camps were kept in terrible conditions, with the intention by the Nazis that death would be the result. ‘Extermination by labour’ was a policy under which the Nazis could supply the German war effort, while also continuing to carry out ‘the final solution’.
What of those immigrants who became citizens, or those beleaguered minorities to whom the United States granted the privileges of citizenship? Despite an avowed declaration of constitutional equality, citizenship was under its own separate-but-equal doctrine. Until 1924, Native Americans were considered “nationals” and not citizens. After the Spanish-American War of 1898, Puerto Ricans and Filipinos were legally classified as “non-citizen nationals.” Most infamously, the 1857 Dred Scott decision held that African Americans were not citizens, and even after the Civil War, black people were legally relegated to third-class status. The Nazis took interest in all of this; the second Nuremburg Law confined citizenship to that person who “is exclusively a national of German blood, or racially related blood.” Jews were denaturalized, rendered subjects. The U.S. precedent laid out how to create a hierarchy of citizens, nationals, and subjects. Tiered citizenship and the capricious revocations of civil rights were of great interest to Nazi intellectuals.
This intellectual preparation would probably not have been sufficient for the growth of Nazism in Germany but for that country’s defeat in World War I. The defeat and the resulting disillusionment, pauperization, and frustration—particularly among the lower middle classes—paved the way for the success of the propaganda of Hitler and the Nazis. The Treaty of Versailles (1919), the formal settlement of World War I drafted without German participation, alienated many Germans with its imposition of harsh monetary and territorial reparations. The significant resentment expressed toward the peace treaty gave Hitler a starting point. Because German representatives (branded the “November criminals” by National Socialists) agreed to cease hostilities and did not unconditionally surrender in the armistice of November 11, 1918, there was a widespread feeling—particularly in the military—that Germany’s defeat had been orchestrated by diplomats at the Versailles meetings. From the beginning, Hitler’s propaganda of revenge for this “traitorous” act, through which the German people had been “stabbed in the back,” and his call for rearmament had strong appeal within military circles, which regarded the peace only as a temporary setback in Germany’s expansionist program. The ruinous inflation of the German currency in 1923 wiped out the savings of many middle-class households and led to further public alienation and dissatisfaction.
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.
Anneliese (Annelies) Marie Frank was born June 12, 1929 to Otto and Edith (Holländer) Frank in Frankfurt, Germany. Her older sister, Margot, was born February 16, 1926. Her father, Otto, was an officer in the German army during World War I on the Western Front and began working for the family bank in Aachen, Germany, after returning from the war. The bank collapsed in the early 1930s during Germany’s economic depression, a depression that further enflamed long-standing anti-Semitism and gave rise to Adolf Hitler’s National Socialist German Workers Party—the Nazis.
The arrests took place in various ways, partly through the S.A. or S.S., partly through uniformed police, partly through plain-clothes men or secret police. It was the latter in my case. There appeared suddenly at our door a group of three men in civilian clothes, identified by their badges as policemen, who took us away in a car after having established through questioning that we were 'non-Aryans.' They also arrested a gentleman who happened to be visiting us. They had no warrants, and declined to give any information about our further destiny; our families for days were without any idea of what had happened to us. We were brought into the courtyard of the police headquarters, our names and addresses were taken down, and without any further hearing we were loaded into large trucks covered with canvas, in which benches had been placed. For the older people—and the majority were over fifty—a chair had been provided so that they might climb into the truck more easily. We mention this here especially because the treatment of the uniformed police in charge of the transportation differed pleasantly from the treatment we suffered in the camp at the hands of the S.S. The crowds in the streets took little notice of the police trucks driving in a row. Only a few urchins around the police headquarters greeted us with howling.
The Theresienstadt family camp, which existed between September 1943 and July 1944, served a different purpose. A group of around 5,000 Jews had arrived in Auschwitz in September 1943 from the Theresienstadt ghetto in Czechoslovakia. The families were allowed to stay together, their heads were not shaved, and they could wear their own clothes. Correspondence between Adolf Eichmann's office and the International Red Cross suggests that the Germans set up the camp to cast doubt on reports, in time for a planned Red Cross visit to Auschwitz, that mass murder was taking place in Auschwitz. A second group of 5,000 arrived from Theresienstadt in December 1943. On 7 March 1944, the first group was sent to the gas chamber at crematorium III; before they died, they were asked to send postcards to relatives, postdated to 25 March.[149] This was the largest massacre of Czechoslovak citizens in history. News of the liquidation reached the Czechoslovak government-in-exile, which initiated diplomatic manoeuvers to save the remaining Jews. After the Red Cross visited Theresienstadt in June 1944 and were persuaded by the SS that no deportations were taking place from there, about 3,500 Jews were removed from the family camp to other sections of Auschwitz. The remaining 6,500 were murdered in the gas chambers between 10 and 12 July 1944.[150][151]
Syria: Kurds make up perhaps 15 percent of the population and live mostly in the northeastern part of Syria. In 1962, after Syria was declared an Arab republic, a large number of Kurds were stripped of their citizenship and declared aliens, which made it impossible for them to get an education, jobs, or any public benefits. Their land was given to Arabs. The PYD was founded in 2003 and immediately banned; its members were jailed and murdered, and a Kurdish uprising in Qamishli was met with severe military violence by the regime. When the uprising against Bashar al Assad began as part of the Arab Spring, Kurds participated, but after 2012, when they captured Kobani from the Syrian army, they withdrew most of their energy from the war against Assad in order to set up a liberated area. For this reason, some other parts of the Syrian resistance consider them Assad’s allies. The Kurds in turn cite examples of discrimination against them within the opposition.
I remember the night of the packing very well. Things went in the suitcase, things were taken out of the suitcase. In the end my mother filled it with food she had cooked and warm clothing and bedding. Then it was full. Plus we took a watch, some earrings, a wedding ring with us to exchange for food if necessary. The next day my father was forced to hand over his remaining money to a delegation that included the mayor and the school principal as they rounded us up at the town hall.
The Reichskulturkammer (Reich Chamber of Culture) was organised under the control of the Propaganda Ministry in September 1933. Sub-chambers were set up to control aspects of cultural life such as film, radio, newspapers, fine arts, music, theatre and literature. Members of these professions were required to join their respective organisation. Jews and people considered politically unreliable were prevented from working in the arts, and many emigrated. Books and scripts had to be approved by the Propaganda Ministry prior to publication. Standards deteriorated as the regime sought to use cultural outlets exclusively as propaganda media.[455]

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]
In Italy I joined the Irgun, the Zionist underground organisation fighting for Israeli independence led by Menachem Begin (later prime minister of Israel), and travelled with an arms smuggling ship, the Altalena, to Tel Aviv. All the time I kept with me my prison uniform, as proof of what had happened to me. We arrived on the shores of Tel Aviv on 20 June 1948 and I found myself at a pivotal moment in Israeli history, in a boat full of weapons that Ben-Gurion would not let on shore. It could easily have turned into a civil war. I was shot at by Israel Defence Force troopers as I jumped into the water and the Altalena was set ablaze and sunk by the IDF. With it sank my suitcase of clothes and my striped prisoner uniform, including my hat, coat, shirt and a knife.
The Nazis’ goal wasn’t only to destroy evidence of the camp: They had plans to force the prisoners to serve as slave laborers for the Reich. Some prisoners were stuffed into train cars to complete their journey to Germany; others escaped into the sub-zero temperatures. Of those forced to walk, some died along the way, though it remains unclear how many were killed over the course of the marches.
Anneliese (Annelies) Marie Frank was born June 12, 1929 to Otto and Edith (Holländer) Frank in Frankfurt, Germany. Her older sister, Margot, was born February 16, 1926. Her father, Otto, was an officer in the German army during World War I on the Western Front and began working for the family bank in Aachen, Germany, after returning from the war. The bank collapsed in the early 1930s during Germany’s economic depression, a depression that further enflamed long-standing anti-Semitism and gave rise to Adolf Hitler’s National Socialist German Workers Party—the Nazis.
The Generalplan Ost ("General Plan for the East") called for deporting the population of occupied Eastern Europe and the Soviet Union to Siberia, for use as slave labour or to be murdered.[321] To determine who should be killed, Himmler created the Volksliste, a system of classification of people deemed to be of German blood.[322] He ordered that those of Germanic descent who refused to be classified as ethnic Germans should be deported to concentration camps, have their children taken away, or be assigned to forced labour.[323][324] The plan also included the kidnapping of children deemed to have Aryan-Nordic traits, who were presumed to be of German descent.[325] The goal was to implement Generalplan Ost after the conquest of the Soviet Union, but when the invasion failed Hitler had to consider other options.[321][326] One suggestion was a mass forced deportation of Jews to Poland, Palestine, or Madagascar.[317]
The Diary of a Young Girl, as it's typically called in English, has since been published in 67 languages. Countless editions, as well as screen and stage adaptations, of the work have been created around the world. The Diary of a Young Girl remains one of the most moving and widely read firsthand accounts of the Jewish experience during the Holocaust.
During the German invasion of the Soviet Union the Nazis began the first mass killings of Jews. Between June and September 1941, the Einsatzgruppen supported by local collaborators murdered hundreds of thousands of Jews across Latvia, Lithuania, Estonia and the Soviet Union. Having observed the killings, Adolf Eichmann ordered a more efficient method of killing the Jews of Europe be developed.

An inmate's first encounter with the camp, if they were being registered and not sent straight to the gas chamber, would be at the prisoner reception centre, where they were tattooed, shaved, disinfected, and given their striped prison uniform. Built between 1942 and 1944, the center contained a bathhouse, laundry, and 19 gas chambers for delousing clothes. Debórah Dwork and Robert Jan van Pelt write that inmates would then leave this area via a porch that faced the gate with the Arbeit macht frei sign. The prisoner reception center of Auschwitz I became the visitor reception center of the Auschwitz-Birkenau Memorial and Museum.[20]

The third camp, Auschwitz III, also called Monowitz, was opened in October 1942. It was predominantly used as a base for imprisoned labourers working for the German chemical company IG Farben. According to the Auschwitz-Birkenau memorial museum, an estimated 10,000 labourers are thought to have died there. Once they were judged incapable of work, most were killed with a phenol injection to the heart.
At the end of 1944 and early in 1945, a complete deterioration of living conditions set in as thousands of survivors of death marches began to arrive at the camp. The large numbers arriving at the camp soon overwhelmed the meagre resources available. The camp administration did not attempt to house them. Serious overcrowding and a lack of sanitary facilities resulted in the break-out of a typhus epidemic. From January to mid-April 1945, some 35,000 prisoners died due to typhus, starvation and the terrible conditions within the camp.
The Allied powers organised war crimes trials, beginning with the Nuremberg trials, held from November 1945 to October 1946, of 23 top Nazi officials. They were charged with four counts—conspiracy to commit crimes, crimes against peace, war crimes and crimes against humanity—in violation of international laws governing warfare.[483] All but three of the defendants were found guilty and twelve were sentenced to death.[484] Twelve Subsequent Nuremberg trials of 184 defendants were held between 1946 and 1949.[483] Between 1946 and 1949, the Allies investigated 3,887 cases, of which 489 were brought to trial. The result was convictions of 1,426 people; 297 of these were sentenced to death and 279 to life in prison, with the remainder receiving lesser sentences. About 65 percent of the death sentences were carried out.[485] Poland was more active than other nations in investigating war crimes, for example prosecuting 673 of the total 789 Auschwitz staff brought to trial.[486]
Deportees were brought to Auschwitz crammed in wretched conditions into goods or cattle wagons, arriving near a railway station or at one of several dedicated trackside ramps, including one next to Auschwitz I. The Altejudenrampe (old Jewish ramp), part of the Oświęcim freight railway station, was used from 1942 to 1944 for Jewish transports.[102][103] Located between Auschwitz I and Auschwitz II, arriving at this ramp meant a 2.5 km journey to Auschwitz II and the gas chambers. Most deportees were forced to walk, accompanied by SS men and a car with a Red Cross symbol that carried the Zyklon B, as well as an SS doctor in case officers were poisoned by mistake. Inmates arriving at night, or who were too weak to walk, were taken by truck.[104] Work on another railway line and Judenrampe (pictured right) between sectors BI and BII in Auschwitz II, was completed in May 1944 for the arrival of Hungarian Jews,[103] who between May and early July 1944 were deported to Auschwitz II at a rate of 12,000 a day.[105] The rails led directly to the area around the gas chambers.[102]

Between 1939 and 1945, the Nazi Party led regime, assisted by collaborationist governments and recruits from occupied countries, was responsible for the deaths of at least eleven million people,[94][95] including 5.5 to 6 million Jews (representing two-thirds of the Jewish population of Europe),[11][96][97] and between 200,000 and 1,500,000 Romani people.[98][99] The estimated total number includes the killing of nearly two million non-Jewish Poles,[100] over three million Soviet prisoners of war,[101] communists, and other political opponents, homosexuals, the physically and mentally disabled.[102][103]
^ "Social democracy is objectively the moderate wing of fascism. … These organisations (ie Fascism and social democracy) are not antipodes, they are twins." (J.V. Stalin: Concerning the International Situation (September 1924), in Works, Volume 6, 1953; p. 294.) This later led Otto Wille Kuusinen to conclude that "The aims of the fascists and the social-fascists are the same." (Report To the 10th Plenum of ECCI, in International Press Correspondence, Volume 9, no.40, (20 August 1929), p. 848.)
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]
They did not greet us, nor did they smile; they seemed oppressed not only by compassion but by a confused restraint, which sealed their lips and bound their eyes to the funereal scene. It was that shame we knew so well, the shame that drowned us after the selections, and every time we had to watch, or submit to, some outrage: the shame the Germans did not know, that the just man experiences at another man's crime; the feeling of guilt that such a crime should exist, that it should have been introduced irrevocably into the world of things that exist, and that his will for good should have proved too weak or null, and should not have availed in defence.[252]
During the era of Imperial Germany, Völkisch nationalism was overshadowed by both Prussian patriotism and the federalist tradition of its various component states.[71] The events of World War I, including the end of the Prussian monarchy in Germany, resulted in a surge of revolutionary Völkisch nationalism.[72] The Nazis supported such revolutionary Völkisch nationalist policies[71] and they claimed that their ideology was influenced by the leadership and policies of German Chancellor Otto von Bismarck, the founder of the German Empire.[73] The Nazis declared that they were dedicated to continuing the process of creating a unified German nation state that Bismarck had begun and desired to achieve.[74] While Hitler was supportive of Bismarck's creation of the German Empire, he was critical of Bismarck's moderate domestic policies.[75] On the issue of Bismarck's support of a Kleindeutschland ("Lesser Germany", excluding Austria) versus the Pan-German Großdeutschland ("Greater Germany") which the Nazis advocated, Hitler stated that Bismarck's attainment of Kleindeutschland was the "highest achievement" Bismarck could have achieved "within the limits possible at that time".[76] In Mein Kampf (My Struggle), Hitler presented himself as a "second Bismarck".[76]

Then we were fitted out. Strange combinations! The younger and thinner men received, for the most part, old uniforms, even officers' coats without insignia. Others received striped prisoners' garb of relatively light material, a shirt, a pair of socks, and a suit of tissue-thin underwear. No vest, no coat. As headgear there were old soldiers' caps without cockades. It goes without saying that it was very difficult to find clothes fitting the various sizes and shapes. We were a sight grotesque as well as sad.
But, in May 1944, a railroad spur line was built right into the camp to accelerate and simplify the handling of the tens of thousands of Hungarian and other Jews deported in the spring and summer of 1944. From then to November 1944, when all the other death camps had been abandoned, Birkenau surpassed all previous records for mass killing. The Hungarian deportations and the liquidation of the remaining Polish ghettos, such as Lodz, resulted in the gassing of 585,000 Jews. This period made Auschwitz-Birkenau into the most notorious killing site of all time.
Between 1939 and 1945, the Nazi Party led regime, assisted by collaborationist governments and recruits from occupied countries, was responsible for the deaths of at least eleven million people,[94][95] including 5.5 to 6 million Jews (representing two-thirds of the Jewish population of Europe),[11][96][97] and between 200,000 and 1,500,000 Romani people.[98][99] The estimated total number includes the killing of nearly two million non-Jewish Poles,[100] over three million Soviet prisoners of war,[101] communists, and other political opponents, homosexuals, the physically and mentally disabled.[102][103]
The Germans occupied Amsterdam in May 1940. In July 1942, German authorities and their Dutch collaborators began to concentrate Jews from throughout the Netherlands at Westerbork, a transit camp near the Dutch town of Assen, not far from the German border. From Westerbork, German officials deported the Jews to Auschwitz-Birkenau and Sobibor killing centers in German-occupied Poland.
The concentration camps increasingly became sites where the SS authorities could kill targeted groups of real or perceived enemies of Nazi Germany. They also came to serve as holding centers for a rapidly growing pool of forced laborers used for SS construction projects, SS-commissioned extractive industrial sites, and, by 1942, the production of armaments, weapons, and related goods for the German war effort.
