German authorities begin the deportation of Jews from the Lodz ghetto to the Chelmno killing center.
Between December 1941 and March 1943 and again in June–July 1944, at least 167,000 Jews and approximately 4,300 Roma (Gypsies) are killed at Chelmno. The majority of victims are Jews deported from the Lodz ghetto and other smaller ghettos in the surrounding region. The Jews of Lodz formed the second largest Jewish community in prewar Poland, after Warsaw.
