Chełmno extermination camp in the context of "The Holocaust"

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.

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.

A gas van or gas wagon (Russian: душегубка, romanized: dushegubka, lit. 'soul killer'; Serbian: душегупка/dušegupka; German: Gaswagen) was a truck re-equipped as a mobile gas chamber. During World War II and the Holocaust, Nazi Germany developed and used gas vans on a large scale to kill inmates of asylums, Romany people, Jews, and prisoners in occupied Poland, Belarus, Nedić's Serbia, the Soviet Union, and other regions of German-occupied Europe. There are several documented cases of gas vans used by Soviet NKVD during the Great Purge.

The Chełmno trials were a series of consecutive war-crime trials of the Chełmno extermination camp personnel, held in Poland and in Germany following World War II. The cases were decided almost twenty years apart. The first judicial trial of the former SS men – members of the SS-Sonderkommando Kulmhof – took place in 1945 at the District Court in Łódź, Poland. The subsequent four trials, held in Bonn, Germany, began in 1962 and concluded three years later, in 1965 in Cologne.

A number of camp officials, gas-van operators and SS guards, were arraigned before the court on charges of war crimes and crimes against humanity committed at Chełmno (a.k.a. Kulmhof) in occupied Poland in the period between December 1941 and January 1945. The evidence against the accused, including testimonies by surviving witnesses, former prisoners, and mechanics attending to repair needs of the SS, was examined in Poland by Judge Władysław Bednarz of the Łódź District Court (Sąd Okręgowy w Łodzi). Three convicted defendants were sentenced to death, including the camp deputy commandant Oberscharführer Walter Piller (wrongly, Filer); the gas van operator Hauptscharführer Hermann Gielow (Gilow), as well as Bruno Israel from Ordnungspolizei (Order Police), his sentence was later commuted to life. All three were members of the SS Special Detachment Kulmhof responsible for the extermination of Jews and non-Jews during the Holocaust in occupied Poland.

The Łódź Ghetto, or Litzmannstadt Ghetto (after the Nazi German name for Łódź), was a Nazi ghetto established by the German authorities for Polish Jews and Roma following the Invasion of Poland. It was the second-largest ghetto in all of German-occupied Europe after the Warsaw Ghetto. Situated in the city of Łódź, and originally intended as a preliminary step upon a more extensive plan of creating the Judenfrei province of Warthegau, the ghetto was transformed into a major industrial centre, manufacturing war supplies for Nazi Germany and especially for the Wehrmacht. The number of people incarcerated in it was increased further by the Jews deported from Nazi-controlled territories.

On 30 April 1940, when the gates closed on the ghetto, it housed 163,777 residents. Because of its remarkable productivity, the ghetto managed to survive until August 1944. In the first two years, it absorbed almost 20,000 Jews from liquidated ghettos in nearby Polish towns and villages, as well as 20,000 more from the rest of German-occupied Europe. After the wave of deportations to Chełmno extermination camp beginning in early 1942, and in spite of a stark reversal of fortune, the Germans persisted in eradicating the ghetto: they transported the remaining population to Auschwitz and Chełmno extermination camps, where most were murdered upon arrival. It was the last ghetto in occupied Poland to be liquidated. A total of 210,000 Jews passed through it; but only 877 remained hidden when the Soviets arrived. About 10,000 Jewish residents of Łódź, who used to live there before the invasion of Poland, survived the Holocaust elsewhere.

The Lidice massacre (Czech: Vyhlazení Lidic) was the complete destruction of the village of Lidice in the Protectorate of Bohemia and Moravia, which is now a part of the Czech Republic, in June 1942 on orders from Nazi leader Adolf Hitler and acting Reichsprotektor Kurt Daluege, successor to Reinhard Heydrich. It has gained historical attention as one of the most documented instances of German war crimes during World War II, particularly given the deliberate killing of children.

In reprisal for the assassination of Reich Protector Heydrich in the late spring of 1942, all 173 men and boys from the village aged 15 years or older were killed on 10 June 1942. A further 9 men from the village who were not present at the time were arrested and executed soon afterwards, along with 8 men and 7 women who were already under arrest, and two boys who had recently turned 15. Most of the 203 women and 105 children were sent to a makeshift detention center in a Kladno school, after which the women were deported to concentration camps. 9 children who were considered racially suitable and thus eligible for Germanisation were handed over to German families, and 82 (excluding 14 children either under a year old or born after the massacre) were sent to the Chełmno extermination camp where they were gassed to death.
