The Holocaust: Josef Mengele becomes chief medical officer of the Zigeunerfamilienlager (Romani family camp) at Auschwitz concentration camp.
Auschwitz concentration camp (German: Konzentrationslager Auschwitz (pronounced [kntsntatsionsla avts] (listen)); also KL Auschwitz or KZ Auschwitz) 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 Owicim; 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 gassingsof Soviet and Polish prisonerstook 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 Hss. 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.
The Holocaust, also known as the Shoah, was the genocide of European Jews during World War II. Between 1941 and 1945, Nazi Germany and its collaborators systematically murdered some six million Jews across German-occupied Europe, around two-thirds of Europe's Jewish population. The murders were carried out in pogroms and mass shootings; by a policy of extermination through labor in concentration camps; and in gas chambers and gas vans in German extermination camps, chiefly Auschwitz-Birkenau, Bełżec, Chełmno, Majdanek, Sobibór, and Treblinka in occupied Poland.Germany implemented the persecution in stages. Following Adolf Hitler's appointment as chancellor on 30 January 1933, the regime built a network of concentration camps in Germany for political opponents and those deemed "undesirable", starting with Dachau on 22 March 1933. After the passing of the Enabling Act on 24 March, which gave Hitler dictatorial plenary powers, the government began isolating Jews from civil society; this included boycotting Jewish businesses in April 1933 and enacting the Nuremberg Laws in September 1935. On 9–10 November 1938, eight months after Germany annexed Austria, Jewish businesses and other buildings were ransacked or set on fire throughout Germany and Austria on what became known as Kristallnacht (the "Night of Broken Glass"). After Germany invaded Poland in September 1939, triggering World War II, the regime set up ghettos to segregate Jews. Eventually, thousands of camps and other detention sites were established across German-occupied Europe.
The segregation of Jews in ghettos culminated in the policy of extermination the Nazis called the Final Solution to the Jewish Question, discussed by senior government officials at the Wannsee Conference in Berlin in January 1942. As German forces captured territories in the East, all anti-Jewish measures were radicalized. Under the coordination of the SS, with directions from the highest leadership of the Nazi Party, killings were committed within Germany itself, throughout occupied Europe, and within territories controlled by Germany's allies. Paramilitary death squads called Einsatzgruppen, in cooperation with the German Army and local collaborators, murdered around 1.3 million Jews in mass shootings and pogroms from the summer of 1941. By mid-1942, victims were being deported from ghettos across Europe in sealed freight trains to extermination camps where, if they survived the journey, they were gassed, worked or beaten to death, or killed by disease, starvation, cold, medical experiments, or during death marches. The killing continued until the end of World War II in Europe in May 1945.
The European Jews were targeted for extermination as part of a larger event during the Holocaust era (1933–1945), in which Germany and its collaborators persecuted and murdered millions of others, including ethnic Poles, Soviet civilians and prisoners of war, the Roma, the disabled, political and religious dissidents, and gay men.
