In short: Nazi Germany established six specialized death camps in occupied Poland to carry out the Final Solution. These sites, distinct from standard concentration camps, were engineered for rapid, industrialized killing. By using gas chambers and deception, the regime systematically murdered over 2.7 million people, primarily Jews, in a state-sponsored genocide.

The extermination camps—Chełmno, Bełżec, Sobibór, Treblinka, Majdanek, and Auschwitz-Birkenau—represented a shift in Nazi methodology. While earlier concentration camps served as prisons for political dissidents, these six facilities were built specifically for mass murder. The technology and logistics were adapted from the secretive Aktion T4 euthanasia programme, which had previously targeted hospital patients with disabilities. By 1941, the SS began applying these killing techniques to the Jewish population of Europe.

Operation Reinhard, initiated in late 1941, saw the construction of camps like Bełżec, Sobibór, and Treblinka, which were designed for immediate extermination upon arrival. Victims were often deceived, told they were at transit stops before being led into gas chambers disguised as shower rooms. At these sites, lethal exhaust fumes from internal combustion engines were used, while Auschwitz and Majdanek utilized Zyklon B, a cyanide-based gas. The process was managed by the SS, with slave labor units known as Sonderkommandos forced to assist in the disposal of bodies.

The scale of the genocide was immense, with over 90 percent of extermination camp victims being Jewish. The Nazis made extensive efforts to conceal their crimes, including the destruction of records and the exhumation of mass graves to incinerate remains during Sonderaktion 1005. Despite these attempts at erasure, the existence of the camps is firmly established through survivor testimony, perpetrator accounts, and surviving administrative records. Today, these sites serve as memorials, though their history remains a subject of intense study and debate regarding how to appropriately commemorate the victims.

The distinction between these killing centers and standard concentration camps was clear to the perpetrators themselves. During the Nuremberg trials, officials like Dieter Wisliceny identified Auschwitz and Majdanek as extermination camps, while classifying others like Dachau as normal concentration camps. The legacy of these sites continues to be a focal point for understanding the Holocaust, with annual events like the March of the Living ensuring that the history of the camps remains a central part of global memory.
