The Sosnowiec Ghetto was a World War II ghetto set up by Nazi German authorities for Polish Jews in the Środula district of Sosnowiec in the Province of Upper Silesia. During the Holocaust in occupied Poland, most inmates, estimated at over 35,000 Jewish men, women and children were deported to Auschwitz death camp aboard Holocaust trains following roundups lasting from June until August 1943. The ghetto was liquidated during an uprising, a final act of defiance of its Underground Jewish Combat Organization (ŻOB) made up of youth. Most of the Jewish fighters perished.
