Chełmno extermination camp, also known as the Kulmhof concentration camp, was a Nazi German extermination camp.
The camp operated in two periods, from December 8, 1941 to March 1943, and from June 1944 to January 18, 1945, to kill the Jews of the Łódź Ghetto and the Warthegau.In between these two periods, modifications were made to the camp's killing procedure.
At least 152,000 people were killed in the camp, mainly Poles, Jews from the Łódź Ghetto and the surrounding area, along with Romani from Greater Poland and some Hungarian Jews, Czechs, and Soviet prisoners of war. Most of the victims were killed by the use of gas vans, and the camp served the purpose of early experimentation and development of methods of mass murder, some of which were applied in later phases of The Holocaust.
