In October 1939 the Germans started establishing ghettos in the occupied territory of Poland. Ghettos played an important role in the Jewish extermination policy. They were filled with Polish and Western Europe Jewish deportees. The ghettos differed in length of existence, sizes, internal organization, forms and living conditions. The Germans called them “ death boxes” (Todeskiste).
On September 8, 1939 the German army entered Łódź and straight away the German authorities began oppressing and terrorizing Jews. These actions were based on Nuremberg Laws from 1935 naming Jews to be outlawed without rights as citizens. From November 9, 1939 Łódź was governed by Artur Greiser whose idea was to germanize the area as soon as possible. He issued a number of ruthless regulations.
