The Łódź Ghetto or Litzmannstadt Ghetto (after the Nazi German name for Łódź) was a Nazi ghetto established by the German authorities for Polish Jews and Roma following the Invasion of Poland. It was the second-largest ghetto in all of German-occupied Europe after the Warsaw Ghetto. Situated in the city of Łódź, and originally intended as a preliminary step upon a more extensive plan of creating the "Judenfrei" province of Warthegau, the ghetto was transformed into a major industrial centre, manufacturing war supplies for Nazi Germany and especially for the Wehrmacht. The number of people incarcerated in it was increased further by the Jews deported from the Third Reich territories.
