The first ghetto was established in Lodz, Poland, on February 8, 1940. Approximately 155,000 Jews, almost one-third of the city’s total population, were forced to live in the Lodz ghetto. As Lodz was a center of textile production, this ghetto was of considerable economic importance to the German war machine. Jews played an important role as workers in the textile factories there. For this reason, the deportation of Jews from the Lodz ghetto was only completed in August 1944.
