ユダヤ人戦闘組織
The ghettos were eliminated when their inhabitants were shipped to slave labor and extermination camps. The Łódź Ghetto, one of the largest and most isolated, lasted also the longest (from April 1940 until August 1944), because goods were manufactured there for the Nazi war economy. The deportations from the Warsaw Ghetto began in July 1942. They were facilitated by collaborators, such as the Jewish police, and opposed by the resistance, including the Jewish Combat Organization (ŻOB). An estimated 500,000 Jews died in the ghettos, and further 250,000 were murdered during their elimination.
