Extermination through labour is a term sometimes used to describe the operation of concentration camp, death camp and forced labour systems in Nazi Germany, Soviet Union, North Korea, and elsewhere, defined as the willful or accepted killing of forced labourers or prisoners through excessively heavy labour, malnutrition and inadequate care.
The term "extermination through labour" (Vernichtung durch Arbeit) was not generally used by the Nazi SS but the phrase was notably used in the fall of 1942 in negotiations between Albert Bormann, Joseph Goebels, Otto Georg Thierack and Heinrich Himmler, relating to the transfer of prisoners to concentration camps. Thierack and Goebbels specifically used the term. The phrase was used again during the post-war Nuremberg trials.
In the 1980s and 1990s, however, historians have debated the appropriate use of the term. Falk Pingel believed the phrase should not be applied to all Nazi prisoners, while Hermann Kaienburg and Miroslav Kárný believed "extermination through labour" was a consistent goal of the SS. More recently, Jens-Christian Wagner has also argued that not all Nazi prisoners were targeted with annihilation.
