Auschwitz concentration camp in the context of "Prisoner-of-war camp"

The Holocaust (/ˈhɒləkɔːst/ HOL-ə-kawst), known in Hebrew as the Shoah (/ˈʃoʊə/ SHOH-ə; Hebrew: שּׁוֹאָה, romanized: Shoah, IPA: [ʃoˈʔa], lit. 'Catastrophe'), was the genocide of European Jews during World War II. From 1941 to 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 committed primarily through mass shootings across Eastern Europe and poison gas chambers in extermination camps, chiefly Auschwitz-Birkenau, Treblinka, Belzec, Sobibor, and Chełmno in occupied Poland. Separate Nazi persecutions killed millions of other non-Jewish civilians and prisoners of war (POWs); the term Holocaust is sometimes used to include the murder and persecution of non-Jewish groups.

The Nazis developed their ideology based on racism and pursuit of "living space", and seized power in early 1933. Meant to force all German Jews to emigrate, regardless of means, the regime passed anti-Jewish laws, encouraged harassment, and orchestrated a nationwide pogrom known as Kristallnacht in November 1938. After Germany's invasion of Poland in September 1939, occupation authorities began to establish ghettos to segregate Jews. Following the June 1941 invasion of the Soviet Union, 1.5 to 2 million Jews were shot by German forces and local collaborators. By early 1942, the Nazis decided to murder all Jews in Europe. Victims were deported to extermination camps where those who had survived the trip were killed with poisonous gas, while others were sent to forced labor camps where many died from starvation, abuse, exhaustion, or being used as test subjects in experiments. Property belonging to murdered Jews was redistributed to the German occupiers and other non-Jews. Although the majority of Holocaust victims died in 1942, the killing continued until the end of the war in 1945.

Crimes against humanity are certain crimes committed as part of a large-scale attack against civilians. Unlike war crimes, crimes against humanity can be committed during both peace and war and against a state's own nationals as well as foreign nationals. Together with war crimes, genocide, and the crime of aggression, crimes against humanity are one of the core crimes of international criminal law and, like other crimes against international law, have no temporal or jurisdictional limitations on prosecution (where universal jurisdiction is recognized).

The first prosecution for crimes against humanity took place during the Nuremberg trials and Subsequent Nuremberg trials against defeated leaders of Nazi Germany and collaborators. Crimes against humanity have been prosecuted by other international courts (such as the International Criminal Tribunal for the former Yugoslavia, the International Criminal Tribunal for Rwanda, the Special Court for Sierra Leone, the Extraordinary Chambers in the Courts of Cambodia, and the International Criminal Court) as well as by domestic courts. The law of crimes against humanity has primarily been developed as a result of the evolution of customary international law. Crimes against humanity are not codified in an international convention, so an international effort to establish such a treaty, led by the Crimes Against Humanity Initiative, has been underway since 2008.

Nazi Germany used six extermination camps (German: Vernichtungslager), also called death camps (Todeslager), or killing centers (Tötungszentren), in Central Europe, primarily in German-occupied Poland, during World War II to systematically murder over 2.7 million people—mainly Jews—in the Holocaust. The victims of death camps were primarily murdered by gassing, either in permanent installations constructed for this specific purpose, or by means of gas vans. The six extermination camps were Chełmno, Bełżec, Sobibor, Treblinka, Majdanek and Auschwitz-Birkenau. Extermination through labour was also used at the Auschwitz and Majdanek death camps. Millions were also murdered in concentration camps, in the Aktion T4, or directly on site. Additionally, camps operated by Nazi allies have also been described as extermination or death camps, most notably the Jasenovac concentration camp in the Independent State of Croatia.

The National Socialists made no secret of the existence of concentration camps as early as 1933, as they served as a deterrent to resistance. The extermination camps, on the other hand, were kept strictly secret. To disguise the mass murder, even in internal correspondence, they only referred to it as "special treatment," "cleansing," "resettlement," or "evacuation." The SS referred to the extermination camps as concentration camps. Their internal organizational structures were also largely identical. The term "extermination camp" was only used later in historical scholarship and in court cases and serves to further categorize the camps.

Nazi human experimentation was a series of medical experiments on prisoners by Nazi Germany in its concentration camps mainly between 1942 and 1945. There were 15,754 documented victims, of various nationalities and ages, although the true number is believed to be more. About a quarter of documented victims were killed and survivors generally experienced severe permanent injuries.

At Auschwitz and other camps, under the direction of Eduard Wirths, selected inmates were subjected to various experiments that were designed to help German military personnel in combat situations, develop new weapons, aid in the recovery of military personnel who had been injured, and to advance Nazi racial ideology and eugenics, including the twin experiments of Josef Mengele. Aribert Heim conducted similar medical experiments at Mauthausen.

The Holocaust saw the ghettoization, robbery, deportation and mass murder of Jews, alongside other groups under similar racial pretexts in occupied Poland by the Nazi Germany. Over three million Polish Jews were murdered, primarily at the Chełmno, Belzec, Sobibor, Treblinka and Auschwitz extermination camps, who made up half of the Jewish Holocaust victims.

During Nazi occupation, the country lost 20% of its population, or six million people, including three million Jews (90% of the country's Jewish population). All Poles, Christian or Jewish, were bound for total annihilation. In 1939, Nazi Germany invaded Poland while the Soviet Union invaded Poland from the east. In German-occupied Poland, Jews were killed, subjected to forced labor, and forced to move to ghettos. Some 7,000 Jews were killed in 1939, but open mass killings subsided until June of 1941. The Soviet Union deported many Jews to the Soviet interior, where most survived the war. In 1941, Germany invaded the Soviet Union and began the systematic murder of Jews. 1.8 million Jews were killed in Operation Reinhard, shot in roundups in ghettos, died during the train journey, or killed by poison gas in the extermination camps. In 1943 and 1944, the remaining labor camps and ghettos were liquidated. Many Jews tried to escape, but surviving in hiding was very difficult due to factors such as the lack of money to pay helpers and the risk of denunciation. Only 1 to 2 percent of Polish Jews in German-occupied territory survived. After the war, survivors faced difficulties in regaining their property and rebuilding their lives. Especially after the Kielce pogrom, many fled to displaced persons camps in Allied-occupied Germany.

Hermine "Miep" Gies (Dutch: [mip ˈxis]; née Santrouschitz; 15 February 1909 – 11 January 2010) was one of the Dutch citizens who hid Anne Frank, her family (Otto, Margot, Edith) and four other Dutch Jews (Fritz Pfeffer, Hermann van Pels, Auguste van Pels, Peter van Pels) from the Nazis in an annex above Otto Frank's business premises during World War II. She was Austrian by birth, but in 1920, at the age of eleven, she was taken in as a foster child by a Dutch family in Leiden to whom she became very attached. Although she was only supposed to stay for six months, this stay was extended to one year because of frail health, after which Gies chose to remain with them, living the rest of her life in the Netherlands.

In 1933, Gies began working for Otto Frank, a Jewish businessman who had moved with his family from Germany to the Netherlands in the hope of sparing his family from Nazi persecution. She became a close, trusted friend of the Frank family and was a great support to them during the twenty-five months they spent in hiding. Together with her colleague Bep Voskuijl, she retrieved Anne Frank's diary after the family was arrested, and kept the papers safe until Otto Frank returned from Auschwitz in June 1945 and learned of his younger daughter's death soon afterwards. Gies had stored Anne Frank's papers in the hopes of returning them to the girl, but gave them to Otto Frank, who compiled them into a diary first published in June 1947.

The history of the Jews during World War II is almost synonymous with the persecution and murder of Jews which was committed on an unprecedented scale in Europe and European North Africa (pro-Nazi Vichy-North Africa and Italian Libya). The massive scale of the Holocaust which happened during World War II greatly affected the Jewish people and world public opinion, which only understood the dimensions of the Final Solution after the war. The genocide, known as HaShoah in Hebrew, aimed at the elimination of the Jewish people on the European continent. It was a broadly organized operation led by Nazi Germany, in which approximately six million Jews were murdered methodically and with horrifying cruelty. Although the Holocaust was organized by the highest levels of the Nazi German government, the vast majority of Jews murdered were not German, but were instead residents of countries invaded by the Nazis after 1938. Of the approximately 6 million Jews murdered by the Nazis, approximately 160,000 to 180,000 were German Jews. During the Holocaust in occupied Poland, more than one million Jews were murdered in gas chambers of the Auschwitz concentration camp alone. The murder of the Jews of Europe affected Jewish communities in Albania, Austria, Belarus, Belgium, Bosnia & Herzegovina, Channel Islands, Croatia, Czech Republic, Estonia, France, Germany, Greece, Hungary, Italy, Latvia, Libya, Lithuania, Luxembourg, Moldova, the Netherlands, North Macedonia, Norway, Poland, Romania, Russia, Serbia, Slovakia, and Ukraine.

Leading to World War II, nearly all Jewish businesses in Nazi Germany had either collapsed under financial pressure and declining profits, or had been forced to sell out to the Nazi German government as part of the "Aryanization" policy inaugurated in 1937. As the war started, massacres of Jews took place originally as part of Operation Tannenberg against the Polish nation. The much larger and methodical mass killings of Jews began with the onset of Operation Barbarossa in 1941. Led by Einsatzgruppen and the Order Police battalions, the destruction of European Jews took place with the active participation of local Auxiliary Police including Belarusian, Estonian, Latvian, Lithuanian, and Ukrainian units.

The Kraków Ghetto official name: Jewish Residential District in Krakow (German: Der jüdische Wohnbezirk in Krakau) was one of five major metropolitan Nazi ghettos created by Germany in the new General Government territory during the German occupation of Poland in World War II. It was established for the purpose of exploitation, terror, and persecution of local Polish Jews. The ghetto was later used as a staging area for separating the "able workers" from those to be deported to extermination camps in Operation Reinhard. The ghetto was liquidated between June 1942 and March 1943, with most of its inhabitants deported to the Belzec extermination camp as well as to Płaszów slave-labor camp, and Auschwitz concentration camp, 60 kilometres (37 mi) rail distance.
