Auschwitz I, a former Polish army barracks, was the main camp (Stammlager) and administrative headquarters of the camp complex. Intending to use it to house political prisoners, Reichsführer-SS Heinrich Himmler, head of the Schutzstaffel (SS), approved the site in April 1940 on the recommendation of SS-Obersturmbannführer (lieutenant colonel) Rudolf Höss, then of the Concentration Camps Inspectorate. Höss oversaw the development of the camp and served as its first commandant, with SS-Obersturmführer (senior lieutenant) Josef Kramer as his deputy. Around 1,000 m long and 400 m wide, Auschwitz I consisted of 20 brick buildings, six of them two-story; a second story was added to the others in 1943 and eight new blocks were built. The camp housed the SS barracks and by 1943 held 30,000 inmates. The first 30 prisoners arrived on 20 May 1940 after being transported from the Sachsenhausen concentration camp in Oranienburg, Germany. Convicted German criminals (Berufsverbrecher), the men were known as "greens" after the green triangles they were required to wear on their prison clothing. Brought to the camp as functionaries, this group did much to establish the sadism of early camp life, which was directed particularly at Polish inmates, until the political prisoners began to take over their roles.
Los recintos, las alambradas, las torretas de vigilancia, las casamatas, las horcas, las cámaras de gas y los hornos crematorios de este campo de concentración y exterminio, que fue el más vasto de los creados por el Tercer Reich, dan fe de las condiciones en que se perpetró el genocidio nazi. Según los trabajos de investigación histórica, entre 1.100.000 y 1.500.000 prisioneros –en gran parte judíos– fueron sistemáticamente privados de alimentación, torturados y asesinados en este campo, símbolo de la crueldad ejercida por el hombre contra sus semejantes en el siglo XX.
The impulse to separate some groups of people from the category of the human is, however, a universal one. The enemies we kill in war, the convicted prisoners we lock up for life, even the distant workers who manufacture our clothes and toys—how could any society function if the full humanity of all these were taken into account? In a decent society, there are laws to resist such dehumanization, and institutional and moral forces to protest it. When guards at Rikers Island beat a prisoner to death, or when workers in China making iPhones begin to commit suicide out of despair, we regard these as intolerable evils that must be cured. It is when a society decides that some people deserve to be treated this way—that it is not just inevitable but right to deprive whole categories of people of their humanity—that a crime on the scale of the K.L. becomes a possibility. It is a crime that has been repeated too many times, in too many places, for us to dismiss it with the simple promise of never again. ♦
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". In mid-1944, about 130,000 prisoners were in Auschwitz when the SS moved around half of them to other concentration camps. In November 1944, with the Soviet Red Army approaching through Poland, Himmler ordered gassing operations to cease. The crematorium IV building was dismantled, and the Sonderkommando was ordered to remove evidence of the killings, including the mass graves. The SS destroyed written records, and in the final week before the camp's liberation, burned or demolished many of its buildings. 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.
Of the Jews sent to Bergen-Belsen, very few were set free. One group of 222 Jews reached Palestine after leaving Bergen-Belsen on 10 July 1944. The second group left the camp in two parts – in August and December 1945, the Kasztner transport was sent to Switzerland. Finally, on 25 January 1945, 136 Jews with South American passports reached Switzerland.
In early 1942, at the Wannsee Conference near Berlin, the Nazi Party decided on the last phase of what it called the “Final Solution” of the “Jewish problem” and spelled out plans for the systematic murder of all European Jews. In 1942 and 1943, Jews in the western occupied countries including France and Belgium were deported by the thousands to the death camps mushrooming across Europe. In Poland, huge death camps such as Auschwitz began operating with ruthless efficiency. The murder of Jews in German-occupied lands stopped only in last months of the war, as the German armies were retreating toward Berlin. By the time Hitler committed suicide in April 1945, some 6 million Jews had died.
From the outset, the DAP was opposed to non-nationalist political movements, especially on the left, including the Social Democratic Party of Germany (SPD) and the Communist Party of Germany (KPD). Members of the DAP saw themselves as fighting against "Bolshevism" and anyone considered a part of or aiding so-called "international Jewry". The DAP was also deeply opposed to the Versailles Treaty. The DAP did not attempt to make itself public and meetings were kept in relative secrecy, with public speakers discussing what they thought of Germany's present state of affairs, or writing to like-minded societies in Northern Germany.
Disfigured by a brutal beating, Frank rarely granted interviews; her later work, "The Return," describes how her father did not recognize her upon their reunion in 1945. "The House Behind" was searing and accusatory: The family’s initial hiding place, mundane and literal in the first section, is revealed in the second part to be a metaphor for European civilization, whose facade of high culture concealed a demonic evil. “Every flat, every house, every office building in every city,” she wrote, “they all have a House Behind.” The book drew respectful reviews, but sold few copies.
Auschwitz-Birkenau was also a killing center and played a central role in the German effort to kill the Jews of Europe. Around the beginning of September, 1941, the SS at Auschwitz I conducted the first tests of Zyklon B as a mass murder agent, using Soviet POWs and debilitated Polish prisoners as victims. The “success” of these experiments led to the construction of a chamber in the crematorium of Auschwitz I that, like the subsequent gas chambers at Auschwitz, used Zyklon B to murder victims. The first transports of Jewish men, women, and children sent to Auschwitz as part of the “final solution” were murdered in this gas chamber (Crematorium I) in February and March 1942.
Otto Frank mounted a lawsuit in 1976 against Ernst Römer, who distributed a pamphlet titled "The Diary of Anne Frank, Bestseller, A Lie". When a man named Edgar Geiss distributed the same pamphlet in the courtroom, he too was prosecuted. Römer was fined 1,500 Deutschmarks, and Geiss was sentenced to six months' imprisonment. The sentence of Geiss was reduced on appeal, and the case was eventually dropped following a subsequent appeal because the time limit for filing a libel case had expired.
Aryan mysticism claimed that Christianity originated in Aryan religious traditions, and that Jews had usurped the legend from Aryans. Houston Stewart Chamberlain, an English-born German proponent of racial theory, supported notions of Germanic supremacy and antisemitism in Germany. Chamberlain's work, The Foundations of the Nineteenth Century (1899), praised Germanic peoples for their creativity and idealism while asserting that the Germanic spirit was threatened by a "Jewish" spirit of selfishness and materialism. Chamberlain used his thesis to promote monarchical conservatism while denouncing democracy, liberalism and socialism. The book became popular, especially in Germany. Chamberlain stressed a nation's need to maintain its racial purity in order to prevent its degeneration and argued that racial intermingling with Jews should never be permitted. In 1923, Chamberlain met Hitler, whom he admired as a leader of the rebirth of the free spirit. Madison Grant's work The Passing of the Great Race (1916) advocated Nordicism and proposed that a eugenics program should be implemented in order to preserve the purity of the Nordic race. After reading the book, Hitler called it "my Bible".
The term "National Socialism" arose out of attempts to create a nationalist redefinition of "socialism", as an alternative to both international socialism and free market capitalism. Nazism rejected the Marxist concept of class conflict, opposed cosmopolitan internationalism, and sought to convince all parts of the new German society to subordinate their personal interests to the "common good", accepting political interests as the main priority of economic organization.
By 1942, Auschwitz had mushroomed into a massive money-making complex that included the original camp, Birkenau (officially labeled Auschwitz II) and 40 sub-camps (mostly located in and around the nearby town of Oswiecim but some as far away as Czechoslovakia) set up to provide slave labor for chemical plants, coal mines, shoe factories and other ventures. In their eagerness to carry out orders, advance their careers and line their own pockets, mid-level bureaucrats like Höss implemented what came to be known as the Holocaust.
Gradowski was one of the Jewish prisoners in Auschwitz’s Sonderkommando: those forced to escort new arrivals into the gas chambers, haul the newly dead bodies to the crematoriums, extract any gold teeth and then burn the corpses. Gradowski, a young married man whose entire family was murdered, reportedly maintained his religious faith, reciting the kaddish (mourner’s prayer) each evening for the victims of each transport—including Peter van Pels’ father, who was gassed a few weeks after his arrival in Auschwitz on September 6, 1944. Gradowski recorded his experiences in Yiddish in documents he buried, which were discovered after the war; he himself was killed on October 7, 1944, in a Sonderkommando revolt that lasted only one day. (The documents written by Gradowski and several other prisoners inspired the 2015 Hungarian film Son of Saul, which, unsurprisingly, was no blockbuster, despite an Academy Award and critical acclaim.)
On 4 September 2003, despite a protest from the museum, three Israeli Air Force F-15 Eagles performed a fly-over of Auschwitz II-Birkenau during a ceremony at the camp below. All three pilots were descendants of Holocaust survivors, including the man who led the flight, Major-General Amir Eshel. On 27 January 2015, some 300 Auschwitz survivors gathered with world leaders under a giant tent at the entrance to Auschwitz II to commemorate the 70th anniversary of the camp's liberation.[i]
From March 1944, Bergen-Belsen gradually became a concentration camp. The Germans initially began transferring, from other camps, prisoners they classified as ‘unfit to work’. As more transports arrived from Flossenbürg, Gross-Rosen, Ravensbrück, Neuengamme, Mauthausen, and Buchenwald concentration camps, the prisoners were housed in the former ‘prisoners’ camp’. German convicts, transferred from Dora, served as ‘block elders’ and Kapos. They treated other inmates brutally.
Nazis constructed gas chambers (rooms that filled with poison gas to kill those inside) to increase killing efficiency and to make the process more impersonal for the perpetrators. At the Auschwitz camp complex, the Birkenau killing center had four gas chambers. During the height of deportations to the camp in 1943-44, an average of 6,000 Jews were gassed there each day.
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. To determine who should be killed, Himmler created the Volksliste, a system of classification of people deemed to be of German blood. 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. The plan also included the kidnapping of children deemed to have Aryan-Nordic traits, who were presumed to be of German descent. 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. One suggestion was a mass forced deportation of Jews to Poland, Palestine, or Madagascar.
If, up to now, we had interpreted our fate only as a privation of liberty, our experience changed rapidly. We had to jump down from the truck without the aid of a chair, and the request for a helping hand was denied with abuse. One of our comrades, an older man lacking the agility of youth, fell in this enforced jump and hurt the back of his head so badly that his skin had to be sewed with several stitches. Hardly were we standing on the ground when a pack of young men in S.S. uniforms, with yells and abuse, chased us to the other end of the large, inner, so-called inspection ground, which is surrounded by the barracks of the prisoners. Those who couldn't run fast enough were kicked.
When I met her at her house in London, Lasker-Wallfisch, 84, explained that she and her sister avoided the dreaded selection process because they went to Birkenau as convicts. “People shipped from prisons weren’t shipped in huge trainloads of Jews,” Lasker-Wallfisch said. “They were shipped as individuals, which was an advantage. It’s not worth turning the gas on for one Jew, I suppose.” Instead, Lasker-Wallfisch was stripped, guards shaved her head and an inmate tattooed her with an identification number (a practice unique to Auschwitz).
At Auschwitz I, the majority of the complex has remained intact. The architecture of the camp consisted mostly of pre-existing buildings converted by the Nazis to serve new functions. The preserved architecture, spaces and layout still recall the historical functions of the individual elements in their entirety. The interiors of some of the buildings have been modified to adapt them to commemorative purposes, but the external façades of these buildings remain unchanged.
Nazism subscribed to theories of racial hierarchy and Social Darwinism, identifying the Germans as a part of what the Nazis regarded as an Aryan or Nordic master race. It aimed to overcome social divisions and create a German homogeneous society based on racial purity which represented a people's community (Volksgemeinschaft). The Nazis aimed to unite all Germans living in historically German territory, as well as gain additional lands for German expansion under the doctrine of Lebensraum and exclude those who they deemed either community aliens or "inferior" races.
In 1923, Hitler and his followers staged the Beer Hall Putsch in Munich, a failed takeover of the government in Bavaria, a state in southern Germany. Hitler had hoped that the “putsch,” or coup d’etat, would spark a larger revolution against the national government. In the aftermath of the Beer Hall Putsch, Hitler was convicted of treason and sentenced to five years in prison, but spent less than a year behind bars (during which time he dictated the first volume of “Mein Kampf,” or “My Struggle,” his political autobiography). The publicity surrounding the Beer Hall Putsch and Hitler’s subsequent trial turned him into a national figure. After his release from prison, he set about rebuilding the Nazi Party and attempting to gain power through the election process.
The Protocols of the Elders of Zion (1912) is an antisemitic forgery created by the secret service of the Russian Empire, the Okhrana. Many antisemites believed it was real and thus it became widely popular after World War I. The Protocols claimed that there was a secret international Jewish conspiracy to take over the world. Hitler had been introduced to The Protocols by Alfred Rosenberg and from 1920 onwards he focused his attacks by claiming that Judaism and Marxism were directly connected, that Jews and Bolsheviks were one and the same and that Marxism was a Jewish ideology-this became known as "Jewish Bolshevism". Hitler believed that The Protocols were authentic.
The process of denazification, which was initiated by the Allies as a way to remove Nazi Party members was only partially successful, as the need for experts in such fields as medicine and engineering was too great. However, expression of Nazi views was frowned upon, and those who expressed such views were frequently dismissed from their jobs. From the immediate post-war period through the 1950s, people avoided talking about the Nazi regime or their own wartime experiences. While virtually every family suffered losses during the war has a story to tell, Germans kept quiet about their experiences and felt a sense of communal guilt, even if they were not directly involved in war crimes.
Large segments of the Nazi Party, particularly among the members of the Sturmabteilung (SA), were committed to the party's official socialist, revolutionary and anti-capitalist positions and expected both a social and an economic revolution when the party gained power in 1933. In the period immediately before the Nazi seizure of power, there were even Social Democrats and Communists who switched sides and became known as "Beefsteak Nazis": brown on the outside and red inside. The leader of the SA, Ernst Röhm, pushed for a "second revolution" (the "first revolution" being the Nazis' seizure of power) that would enact socialist policies. Furthermore, Röhm desired that the SA absorb the much smaller German Army into its ranks under his leadership. Once the Nazis achieved power, Röhm's SA was directed by Hitler to violently suppress the parties of the left, but they also began attacks against individuals deemed to be associated with conservative reaction. Hitler saw Röhm's independent actions as violating and possibly threatening his leadership, as well as jeopardising the regime by alienating the conservative President Paul von Hindenburg and the conservative-oriented German Army. This resulted in Hitler purging Röhm and other radical members of the SA in 1934, in what came to be known as the Night of the Long Knives.
From there we were sent to Buna (an Auschwitz sub camp) and were set to work. After a few months there, I went for a walk one day and saw a few tomatoes growing. I was starving by then so tried to take them and was given a beating so severe, I don’t know how I survived it. I still have the scars from it today. I was taken to hospital and knew the rule: if you didn’t heal in four to five days, they’d take you to Birkenau and you’d be gassed.
The first party that attempted to combine nationalism and socialism was the (Austria-Hungary) German Workers' Party, which predominantly aimed to solve the conflict between the Austrian Germans and the Czechs in the multi-ethnic Austrian Empire, then part of Austria-Hungary. In 1896 the German politician Friedrich Naumann formed the National-Social Association which aimed to combine German nationalism and a non-Marxist form of socialism together; the attempt turned out to be futile and the idea of linking nationalism with socialism quickly became equated with antisemites, extreme German nationalists and the Völkisch movement in general.
Nazism had peculiarly German roots. It can be partly traced to the Prussian tradition as developed under Frederick William I (1688–1740), Frederick the Great (1712–68), and Otto von Bismarck (1815–98), which regarded the militant spirit and the discipline of the Prussian army as the model for all individual and civic life. To it was added the tradition of political romanticism, with its sharp hostility to rationalism and to the principles underlying the French Revolution, its emphasis on instinct and the past, and its proclamation of the rights of Friedrich Nietzsche’s exceptional individual (the Übermensch [“Superman”]) over all universal law and rules. These two traditions were later reinforced by the 19th-century adoration of science and of the laws of nature, which seemed to operate independently of all concepts of good and evil. Further reinforcements came from such 19th-century intellectual figures as the comte de Gobineau (1816–82), Richard Wagner (1813–83), and Houston Stewart Chamberlain (1855–1927), all of whom greatly influenced early National Socialism with their claims of the racial and cultural superiority of the “Nordic” (Germanic) peoples over all other Europeans and all other races.
In spite of their rhetoric condemning big business prior to their rise to power, the Nazis quickly entered into a partnership with German business from as early as February 1933. That month, after being appointed Chancellor but before gaining dictatorial powers, Hitler made a personal appeal to German business leaders to help fund the Nazi Party for the crucial months that were to follow. He argued that they should support him in establishing a dictatorship because "private enterprise cannot be maintained in the age of democracy" and because democracy would allegedly lead to communism. He promised to destroy the German left and the trade unions, without any mention of anti-Jewish policies or foreign conquests. In the following weeks, the Nazi Party received contributions from seventeen different business groups, with the largest coming from IG Farben and Deutsche Bank. Historian Adam Tooze writes that the leaders of German business were therefore "willing partners in the destruction of political pluralism in Germany." In exchange, owners and managers of German businesses were granted unprecedented powers to control their workforce, collective bargaining was abolished and wages were frozen at a relatively low level. Business profits also rose very rapidly, as did corporate investment. In addition, the Nazis privatised public properties and public services, but at the same time they increased economic state control through regulations. Hitler believed that private ownership was useful in that it encouraged creative competition and technical innovation, but insisted that it had to conform to national interests and be "productive" rather than "parasitical". Private property rights were conditional upon following the economic priorities set by the Nazi leadership, with high profits as a reward for firms who followed them and the threat of nationalization being used against those who did not. Under Nazi economics, free competition and self-regulating markets diminished, but Hitler's social Darwinist beliefs made him retain business competition and private property as economic engines.
Jewish deportees arriving at Auschwitz-Birkenau immediately underwent selection. The SS staff chose some of the able-bodied for forced labor and sent the rest directly to the gas chambers, which were disguised as shower installations to mislead the victims. The belongings of all deportees were confiscated and sorted in the "Kanada" (Canada) warehouse for shipment back to Germany. Canada symbolized wealth to the prisoners.
Please remember that you are essentially visiting a mass grave site, as well as a site that has an almost incalculable meaning to a significant portion of the world's population. There are still many men and women alive today who survived their internment here, and many more who had loved ones murdered on these grounds, Jews and non-Jews alike. Please treat the site with the dignity and respect it solemnly deserves. Do not make jokes about the Holocaust or the Nazis. Do not deface the site by marking or scratching graffiti into structures. Pictures are permitted in outdoor areas, but remember this is a memorial rather than a tourist attraction, and there will undoubtedly be visitors who have a personal connection with the site, so be discreet with cameras.
Sessions’s characterization falls into a nether region between truth and falsehood. Perhaps his is the best comment to begin with precisely because it is a half-truth. Yes, after 1941, concentration camps held Jews to prevent them from leaving Germany — but also to consolidate them for extermination. However, for more than eight years earlier, the camps generally were used for the opposite purpose: to force Jews to emigrate from Germany by making life intolerable, in part by separating men from their families. This is precisely the kind of important historical nuance lost in the hysteria surrounding Trump’s callous immigration policy. There are valuable comparisons to be made, but they must be historically informed.
Hitler’s most important individual contribution to the theory and practice of Nazism was his deep understanding of mass psychology and mass propaganda. He stressed the fact that all propaganda must hold its intellectual level at the capacity of the least intelligent of those at whom it is directed and that its truthfulness is much less important than its success. According to Hitler:
Forced-Labor Camps and transit camps: Forced labor camps were utilized for pointless and humiliating labor, imposed on prisoners without proper equipment, clothing, nourishment, or rest. Transit camps functioned as temporary holding facilities for Jews awaiting deportation. These camps were usually the last stop before deportations to a killing center. There were 1,830 forced labor and transit camps.
My sister was sent with my mother, while I went to the opposite side. That was the first chance I had to survive. Unbeknown to any of us at the time, two Nazi soldiers had been asked to make a photographic document of the deportation of Hungarian Jews from the moment they got off the train – through the entire system of arriving, going to the bath house and getting their prison clothes – so I ended up in a picture at the very moment I was separated from my sister. It captures me standing alone without my family on the Auschwitz platform, and I’m leaning inwards to see where my little sister has gone.
Newspapers, like other media, were controlled by the state; the Reich Press Chamber shut down or bought newspapers and publishing houses. By 1939, over two thirds of the newspapers and magazines were directly owned by the Propaganda Ministry. The NSDAP daily newspaper, the Völkischer Beobachter ("Ethnic Observer"), was edited by Rosenberg, who also wrote The Myth of the Twentieth Century, a book of racial theories espousing Nordic superiority. Goebbels controlled the wire services and insisted that all newspapers in Germany only publish content favourable to the regime. Under Goebbels, the Propaganda Ministry issued two dozen directives every week on exactly what news should be published and what angles to use; the typical newspaper followed the directives closely, especially regarding what to omit. Newspaper readership plummeted, partly because of the decreased quality of the content and partly because of the surge in popularity of radio. Propaganda became less effective towards the end of the war, as people were able to obtain information outside of official channels.
The public wants facts. But, as evidenced by the outrage at Esquire’s story, something more than what we think of as objective facts is required to craft a representation of reality. Esquire may have wanted to make “Wisconsin a stand-in for the state of our country,” as the Milwaukee Journal Sentinel wrote, to capture the subtle social forces of alienation and resentment that turned out to be strong enough to elect Trump President. But the story also seemed to deliberately withhold judgment; to its detractors, this didn’t feel like objectivity. In an environment that, to many, is the source of perpetual moral crisis, the objective becomes subjective, and vice versa.
Victor Kugler and Johannes Kleiman were arrested and jailed at the penal camp for enemies of the regime at Amersfoort. Kleiman was released after seven weeks, but Kugler was held in various work camps until the war's end. Miep Gies and Bep Voskuijl were questioned and threatened by the Security Police but not detained. They returned to the Achterhuis the following day, and found Anne's papers strewn on the floor. They collected them, as well as several family photograph albums, and Gies resolved to return them to Anne after the war. On 7 August 1944, Gies attempted to facilitate the release of the prisoners by confronting Silberbauer and offering him money to intervene, but he refused.
The Nazis captured 5.75 million Soviet prisoners of war, more than they took from all the other Allied powers combined. Of these, they killed an estimated 3.3 million, with 2.8 million of them being killed between June 1941 and January 1942. Many POWs starved to death or resorted to cannibalism while being held in open-air pens at Auschwitz and elsewhere.
Upon his release Hitler quickly set about rebuilding his moribund party, vowing to achieve power only through legal political means thereafter. The Nazi Party’s membership grew from 25,000 in 1925 to about 180,000 in 1929. Its organizational system of gauleiters (“district leaders”) spread through Germany at this time, and the party began contesting municipal, state, and federal elections with increasing frequency.
After the war, the Allies occupied Germany, outlawed the Nazi Party and worked to purge its influence from every aspect of German life. The party’s swastika flag quickly became a symbol of evil in modern postwar culture. Although Hitler killed himself before he could be brought to justice, a number of Nazi officials were convicted of war crimes in the Nuremberg trials, which took place in Nuremberg, Germany, from 1945 to 1949.
Although he opposed communist ideology, Hitler publicly praised the Soviet Union's leader Joseph Stalin and Stalinism on numerous occasions. Hitler commended Stalin for seeking to purify the Communist Party of the Soviet Union of Jewish influences, noting Stalin's purging of Jewish communists such as Leon Trotsky, Grigory Zinoviev, Lev Kamenev and Karl Radek. While Hitler had always intended to bring Germany into conflict with the Soviet Union so he could gain Lebensraum ("living space"), he supported a temporary strategic alliance between Nazi Germany and the Soviet Union to form a common anti-liberal front so they could defeat liberal democracies, particularly France.
Heinrich Himmler's Schutzstaffel (SS) took full control of the police and the concentration camps throughout Germany in 1934–35. 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. 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 and peaked at 715,000 in January 1945.
