Historical  Information (source: Wikipedia)

The Warsaw Ghetto (Polish: getto warszawskie) was the largest of all the Jewish ghettos in German-occupied Europe during World War II.

It was established by the German authorities in the Muranów neighborhood of the Polish capital between October and November 16, 1940; within the new General Government territory of German-occupied Poland. There were over 400,000 Jews imprisoned there, at an area of 3.4 km2 (1.3 sq mi), with an average of 9.2 persons per room, barely subsisting on meager food rations. From the Warsaw Ghetto, Jews were deported to Nazi camps and mass-killing centers. In the summer of 1942 at least 254,000 Ghetto residents were sent to the Treblinka extermination camp during Großaktion Warschau under the guise of "resettlement in the East" over the course of the summer.

The death toll among the Jewish inhabitants of the Ghetto is estimated to be at least 300,000 killed by bullet or gas, combined with 92,000 victims of rampant hunger and hunger-related diseases, the Warsaw Ghetto Uprising, and the casualties of the final destruction of the Ghetto.
