Killing Centers: An Overview
The Nazis established killing centers in German-occupied Europe during World War II. They built these killing centers exclusively or primarily for the mass murder of human beings. Nazi officials employed assembly-line methods of murder in these facilities.
Key Facts
1
Nazi officials deployed the first killing centers at T4 (“euthanasia”) facilities to murder institutionalized persons with disabilities between 1940 and 1941.
2
Chelmno, the first killing center for the mass murder of Jews, was established in December 1941. In 1942, Belzec, Sobibor, and Treblinka were established as a part of Operation Reinhard with the goal of murdering all the Jews of the General Government.
3
More than 1.1 million people were killed in the Auschwitz-Birkenau labor camp and killing center. Of those, nearly one million were Jews. Those Jews who were not sent directly to the gas chambers were deployed in forced labor.

The Nazis established killing centers for efficient mass murder. Killing centers were almost exclusively “death factories.” They are also referred to as “extermination camps” or “death camps.” Nazi concentration camps, by contrast, served primarily as detention and labor centers. At the killing centers, Nazi officials employed assembly-line methods to murder Jews and other victims. German SS (Schutzstaffel; Protection Squadrons) and police murdered nearly 2,700,000 Jews in the killing centers by asphyxiation with poisonous gas or by shooting.
The European rail network played a crucial role in the implementation of the Final Solution. Jews from Germany and German-occupied Europe were deported by rail to killing centers in occupied Poland, where they were killed. The Germans attempted to disguise their intentions, referring to deportations as "resettlement to the east." The victims were told they were to be taken to labor camps, but in reality, from 1942 onward, deportation meant transit to killing centers for most Jews. Deportations on this scale required the coordination of numerous German government ministries, including the Reich Security Main Office (RSHA), the Transport Ministry, and the Foreign Office. The RSHA coordinated and directed the deportations; the Transport Ministry organized train schedules; and the Foreign Office negotiated with German-allied states to hand over their Jews.
Killing centers (also referred to as "extermination camps" or "death camps") were designed to carry out genocide. Between 1941 and 1945, the Nazis established five killing centers in German-occupied Poland—Chelmno, Belzec, Sobibor, Treblinka, and Auschwitz-Birkenau (part of the Auschwitz camp complex). Chelmno and Auschwitz were established in areas annexed to Germany in 1939. The other camps (Belzec, Sobibor, and Treblinka) were established in the General Government (an administrative unit of occupied Poland). Auschwitz functioned as concentration and forced-labor camps, as well as a killing center. The overwhelming majority of the victims of the killing centers were Jews. An estimated 2.7 million Jews were killed in these five killing centers as part of the Final Solution. Other victims murdered in the killing centers included Roma (Gypsies) and Soviet prisoners of war.
On this map, the Majdanek camp is labeled as a killing center. In the past, many scholars counted the Majdanek camp (located just outside the city of Lublin) as a sixth killing center. However, based on newer research, Lublin-Majdanek is usually classified as a concentration camp. According to this research, German authorities used Majdanek primarily as a place to concentrate Jews who were being temporarily spared for use as forced laborers. Occasionally, especially after Belzec ceased operating in late 1942, Jews were sent to Majdanek as part of Operation Reinhard to undergo selection. Jews selected as unfit for labor were murdered at Lublin-Majdanek either by shooting or in the camp's gas chambers.
At the Wannsee Conference in Berlin in January 1942, the SS (the elite guard of the Nazi state) and representatives of German government ministries estimated that the "Final Solution," the Nazi plan to kill the Jews of Europe, would involve 11 million European Jews, including those from non-occupied countries such as Ireland, Sweden, Turkey, and Great Britain. Jews from Germany and German-occupied Europe were deported by rail to the killing centers(sometimes referred to as "extermination camps”) in occupied Poland, where they were killed. The Germans attempted to disguise their intentions, referring to deportations as "resettlement to the east." The victims were told they were to be taken to labor camps, but in reality, from 1942 onward, deportation for most Jews meant transit to killing centers and then death.

Jews from Germany, Luxembourg, Austria, and Czechoslovakia during deportation from the Łódź ghetto to the Chełmno killing center. Łódź, Poland, 1942.
In October–November 1941, Nazi German officials deported almost 20,000 Jews from Germany, Austria, Luxembourg, and the Czech lands to the Łódź ghetto. Their arrival compounded the already grim conditions in the ghetto. Transports of Jews from the ghetto to the Chełmno killing center began on January 16, 1942. At first, this group of Jews was spared. But in May 1942, the Nazi German authorities also targeted this group of Jews for transport to Chełmno.
The Germans invaded Poland in September 1939. Leo and his family were confined to a ghetto in Lodz. Leo was forced to work as a tailor in a uniform factory. The Lodz ghetto was liquidated in 1944, and Leo was deported to Auschwitz. He was then sent to the Gross-Rosen camp system for forced labor. As the Soviet army advanced, the prisoners were transferred to the Ebensee camp in Austria. The Ebensee camp was liberated in 1945.

Fritzie's father immigrated to the United States, but by the time he could bring his family over, war had begun and Fritzie's mother feared attacks on transatlantic shipping. Fritzie, her mother, and two brothers were eventually sent to Auschwitz. Her mother and brothers died. Fritzie survived by pretending to be older than her age and thus a stronger worker. On a death march from Auschwitz, Fritzie ran into a forest, where she was later liberated.
The Germans invaded Poland in September 1939. When Makow was occupied, Sam fled to Soviet territory. He returned to Makow for provisions, but was forced to remain in the ghetto. In 1942, he was deported to Auschwitz. As the Soviet army advanced in 1944, Sam and other prisoners were sent to camps in Germany. The inmates were put on a death march early in 1945. American forces liberated Sam after he escaped during a bombing raid.
Abraham was raised in Czestochowa, Poland, and became a barber. He and his family were deported to the Treblinka killing center from the Czestochowa ghetto in 1942. At Treblinka, Abraham was selected for forced labor. He was forced to cut women's hair before they were gassed, and he sorted clothing from arriving transports. Abraham escaped from the camp in 1943 and made his way back to Czestochowa. He worked in a labor camp from June 1943 until liberation by Soviet troops in 1945.
Esther was born to a middle-class Jewish family in Chelm, Poland. In December 1942, she was deported from a work camp to the Sobibor killing center in occupied Poland. Upon arrival at Sobibor, Esther was selected to work in a sorting shed. She sorted clothing and the possessions of the people killed at the camp. During the summer and fall of 1943, Esther was among a group of prisoners in the Sobibor camp who planned an uprising and escape. Leon Feldhendler and Aleksandr (Sasha) Pechersky were the leaders of the group. The revolt took place on October 14, 1943. German and Ukrainian guards opened fire on the prisoners, who were unable to reach the main gate and thus had to try and escape through the minefield around the camp; about 300 escaped. Over 100 of them were recaptured and shot. Esther was among those who escaped and survived.

Operation T4: The Euthanasia Program
Killing centers first appeared in Nazi Germany with Operation T4, the "euthanasia" program. The Euthanasia Program was the systematic murder of institutionalized patients with disabilities in Germany. From January 1940 through late August 1941, some 70,273 adult patients were murdered in gas chambers. These gas chambers employed chemically pure carbon monoxide gas.
Chelmno, Belzec, Sobibor, and Treblinka
To carry out the "Final Solution," the Nazis established killing centers in German-annexed and occupied Poland.
Established in December 1941, Chelmno was the first killing center for the mass murder of Jews. It was located in the Warthegau, the western part of prewar Poland annexed by Germany during World War II. Mostly Jews, but also Roma (Gypsies), were gassed in mobile gas vans at Chelmno.
In 1942, Nazi officials established the Belzec, Sobibor, and Treblinka killing centers in the so-called General Government. Between March 1942 and November 1943, the SS and their auxiliaries murdered approximately 1,526,500 Jews in these three camps. The overwhelming majority of Jews deported to Belzec, Sobibor, and Treblinka were murdered in gas chambers immediately upon arrival. These three killing centers were part of Operation Reinhard, the German plan to systematically murder the remaining Jews in German-occupied Poland. In total, 1.7 million victims were killed in Operation Reinhard and related actions.
At the Chelmno and Operation Reinhard camps, victims were killed using carbon monoxide produced by diesel exhaust.
The largest killing center was Auschwitz-Birkenau. By spring 1943, Auschwitz-Birkenau had four gas chambers in operation. Since the Auschwitz main camp (Auschwitz I) was a labor camp, arriving Jewish prisoners faced a selection process. Those judged best able to work were selected for labor. However, the majority of Jews in the transport were sent immediately to the gas chambers. At the height of the deportations, an average of 6,000 Jews were gassed each day at the Auschwitz II (Birkenau) killing center. These gas chambers used the poisonous gas Zyklon B. By November 1944, more than one million Jews and tens of thousands of Roma, Poles, and Soviet prisoners of war were killed there.
Majdanek
Many scholars have traditionally counted the Majdanek camp, which was located just outside the city Lublin, as a sixth killing center. However, recent research has shed more light on the functions and operations at Lublin-Majdanek.
Within the framework of Operation Reinhard, Majdanek primarily served as a place to concentrate Jews who were spared temporarily for forced labor. Occasionally, especially after Belzec ceased operating in late 1942, Operation Reinhard sent transports of Jews to Majdanek to undergo selection. Jews selected as unfit for labor were murdered either by shooting or in the camp's gas chambers. The Majdanek camp also included a storage depot. There, the Nazis held property and valuables taken from the Jewish victims at the killing centers.
Disguising Mass Murder
The SS considered the killing centers top secret. Sonderkommandos or special prisoner units were deployed to obliterate all traces of gassing operations. These prisoners were forced to remove corpses from the gas chambers and cremate them. The grounds of some killing centers were landscaped or camouflaged to disguise the murder of millions. Moreover, Special Action 1005 (Sonderaktion 1005) began in May 1942. This effort deployed prisoners to exhume and burn bodies from mass graves where cremation was not practiced.
