Birkenau Gate

Auschwitz concentration camp ( (); also or ) was a complex of over 40 concentration and extermination camps operated by Nazi Germany in occupied Poland (in a portion annexed into Germany in 1939) during World War II and the Holocaust. It consisted of Auschwitz I, the main camp (''Stammlager'') in Oświęcim; Auschwitz II-Birkenau, a concentration and extermination camp with gas chambers; Auschwitz III-Monowitz, a labor camp for the chemical conglomerate IG Farben; and dozens of subcamps. The camps became a major site of the Nazis' final solution to the Jewish question.

After Germany sparked World War II by invading Poland in September 1939, the ''Schutzstaffel'' (SS) converted Auschwitz I, an army barracks, into a prisoner-of-war camp.

The initial transport of political detainees to Auschwitz consisted almost solely of Poles for whom the camp was initially established. The bulk of inmates were Polish for the first two years.

In May 1940, German criminals brought to the camp as functionaries, established the camp's reputation for sadism. Prisoners were beaten, tortured, and executed for the most trivial reasons. The first gassings—of Soviet and Polish prisoners—took place in block 11 of Auschwitz I around August 1941. Construction of Auschwitz II began the following month, and from 1942 until late 1944 freight trains delivered Jews from all over German-occupied Europe to its gas chambers. Of the 1.3 million people sent to Auschwitz, 1.1 million were murdered. The number of victims includes 960,000 Jews (865,000 of whom were gassed on arrival), 74,000 ethnic Poles, 21,000 Roma, 15,000 Soviet prisoners of war, and up to 15,000 other Europeans. Those not gassed were murdered via starvation, exhaustion, disease, individual executions, or beatings. Others were killed during medical experiments.

At least 802 prisoners tried to escape, 144 successfully, and on 7 October 1944, two ''Sonderkommando'' units, consisting of prisoners who operated the gas chambers, launched an unsuccessful uprising. Only 789 Schutzstaffel personnel (no more than 15 percent) ever stood trial after the Holocaust ended; several were executed, including camp commandant Rudolf Höss. The Allies' failure to act on early reports of atrocities by bombing the camp or its railways remains controversial.

As the Soviet Red Army approached Auschwitz in January 1945, toward the end of the war, the SS sent most of the camp's population west on a death march to camps inside Germany and Austria. Soviet troops entered the camp on 27 January 1945, a day commemorated since 2005 as International Holocaust Remembrance Day. In the decades after the war, survivors such as Primo Levi, Viktor Frankl, and Elie Wiesel wrote memoirs of their experiences, and the camp became a dominant symbol of the Holocaust. In 1947, Poland founded the Auschwitz-Birkenau State Museum on the site of Auschwitz I and II, and in 1979 it was named a World Heritage Site by UNESCO.

Background

The ideology of National Socialism (Nazism) combined elements of " racial hygiene", eugenics, antisemitism, pan-Germanism, and territorial expansionism, Richard J. Evans writes. Adolf Hitler and his Nazi Party became obsessed by the " Jewish question". Both during and immediately after the Nazi seizure of power in Germany in 1933, acts of violence against German Jews became ubiquitous, and legislation was passed excluding them from certain professions, including the civil service and the law.

Harassment and economic pressure encouraged Jews to leave Germany; their businesses were denied access to markets, forbidden from advertising in newspapers, and deprived of government contracts. On 15 September 1935, the Reichstag passed the Nuremberg Laws. One, the Reich Citizenship Law, defined as citizens those of "German or related blood who demonstrate by their behaviour that they are willing and suitable to serve the German People and Reich faithfully", and the Law for the Protection of German Blood and German Honor prohibited marriage and extramarital relations between those with "German or related blood" and Jews.

When Germany invaded Poland in September 1939, triggering World War II, Hitler ordered that the Polish leadership and intelligentsia be destroyed. The area around Auschwitz was annexed to the German Reich, as part of first Gau Silesia and from 1941 Gau Upper Silesia. The camp at Auschwitz was established in April 1940, at first as a quarantine camp for Polish political prisoners. On 22 June 1941, in an attempt to obtain new territory, Hitler invaded the Soviet Union. The first gassing at Auschwitz—of a group of Soviet prisoners of war—took place around August 1941. By the end of that year, during what most historians regard as the first phase of the Holocaust, 500,000–800,000 Soviet Jews had been murdered in mass shootings by a combination of German ''Einsatzgruppen'', ordinary German soldiers, and local collaborators. At the Wannsee Conference in Berlin on 20 January 1942, Reinhard Heydrich outlined the Final Solution to the Jewish Question to senior Nazis, and from early 1942 freight trains delivered Jews from all over occupied Europe to German extermination camps in Poland: Auschwitz, Bełżec, Chełmno, Majdanek, Sobibór, and Treblinka. Most prisoners were gassed on arrival.

Camps

Auschwitz I

Growth

A former World War I camp for transient workers and later a Polish army barracks, Auschwitz I was the main camp (''Stammlager'') and administrative headquarters of the camp complex. Fifty km southwest of Kraków, the site was first suggested in February 1940 as a quarantine camp for Polish prisoners by Arpad Wigand, the inspector of the Sicherheitspolizei (security police) and deputy of Erich von dem Bach-Zelewski, the Higher SS and Police Leader for Silesia. Richard Glücks, head of the Concentration Camps Inspectorate, sent Walter Eisfeld, former commandant of the Sachsenhausen concentration camp in Oranienburg, Germany, to inspect it. Around 1,000 m long and 400 m wide, Auschwitz consisted at the time of 22 brick buildings, eight of them two-story. A second story was added to the others in 1943 and eight new blocks were built.

Reichsführer-SS Heinrich Himmler, head of the SS, approved the site in April 1940 on the recommendation of SS- Obersturmbannführer Rudolf Höss of the camps inspectorate. Höss oversaw the development of the camp and served as its first commandant. The first 30 prisoners arrived on 20 May 1940 from the Sachsenhausen camp. German "career criminals" (''Berufsverbrecher''), the men were known as "greens" (''Grünen'') after the green triangles 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 took over their roles. Bruno Brodniewicz, the first prisoner (who was given serial number 1), became ''Lagerälteste'' (camp elder). The others were given positions such as '' kapo'' and block supervisor.

First mass transport

The first mass transport—of 728 Polish male political prisoners, including Catholic priests and Jews—arrived on 14 June 1940 from Tarnów, Poland. They were given serial numbers 31 to 758. In a letter on 12 July 1940, Höss told Glücks that the local population was "fanatically Polish, ready to undertake any sort of operation against the hated SS men". By the end of 1940, the SS had confiscated land around the camp to create a 40-square-kilometer (15 sq mi) "zone of interest" (''Interessengebiet'') patrolled by the SS, Gestapo and local police. By March 1941, 10,900 were imprisoned in the camp, most of them Poles.

An inmate's first encounter with Auschwitz, if they were registered and not sent straight to the gas chamber, was at the prisoner reception center near the gate with the ''Arbeit macht frei'' sign, where they were tattooed, shaved, disinfected, and given a striped prison uniform. Built between 1942 and 1944, the center contained a bathhouse, laundry, and 19 gas chambers for delousing clothes. The prisoner reception center of Auschwitz I became the visitor reception center of the Auschwitz-Birkenau State Museum.

Crematorium I, first gassings

Construction of crematorium I began at Auschwitz I at the end of June or beginning of July 1940. Initially intended not for mass murder but for prisoners who had been executed or had otherwise died in the camp, the crematorium was in operation from August 1940 until July 1943, by which time the crematoria at Auschwitz II had taken over. By May 1942 three ovens had been installed in crematorium I, which together could burn 340 bodies in 24 hours.

The first experimental gassing took place around August 1941, when Lagerführer Karl Fritzsch, at the instruction of Rudolf Höss, murdered a group of Soviet prisoners of war by throwing Zyklon B crystals into their basement cell in block 11 of Auschwitz I. A second group of 600 Soviet prisoners of war and around 250 sick Polish prisoners were gassed on 3–5 September. The morgue was later converted to a gas chamber able to hold at least 700–800 people. Zyklon B was dropped into the room through slits in the ceiling.

First mass transport of Jews

Historians have disagreed about the date the all-Jewish transports began arriving in Auschwitz. At the Wannsee Conference in Berlin on 20 January 1942, the Nazi leadership outlined, in euphemistic language, its plans for the Final Solution. According to Franciszek Piper, the Auschwitz commandant Rudolf Höss offered inconsistent accounts after the war, suggesting the extermination began in December 1941, January 1942, or before the establishment of the women's camp in March 1942. In ''Kommandant in Auschwitz'', he wrote: "In the spring of 1942 the first transports of Jews, all earmarked for extermination, arrived from Upper Silesia." On 15 February 1942, according to Danuta Czech, a transport of Jews from Beuthen, Upper Silesia (Bytom, Poland), arrived at Auschwitz I and was sent straight to the gas chamber. In 1998 an eyewitness said the train contained "the women of Beuthen". Saul Friedländer wrote that the Beuthen Jews were from the Organization Schmelt labor camps and had been deemed unfit for work. According to Christopher Browning, transports of Jews unfit for work were sent to the gas chamber at Auschwitz from autumn 1941. The evidence for this and the February 1942 transport was contested in 2015 by Nikolaus Wachsmann.

Around 20 March 1942, according to Danuta Czech, a transport of Polish Jews from Silesia and Zagłębie Dąbrowskie was taken straight from the station to the Auschwitz II gas chamber, which had just come into operation. On 26 and 28 March, two transports of Slovakian Jews were registered as prisoners in the women's camp, where they were kept for slave labour; these were the first transports organized by Adolf Eichmann
