Polish Jewish youth are photographed within the Warsaw Ghetto. The Warsaw Ghetto was the largest of all the Jewish ghettos in Nazi-occupied Europe. It was established between October and 16 November 1940, with over 400,000 Jews from the vicinity forcibly relocated to an area of 3.4 km (1.3 sq. mi). From there, at least 254,000 residents were sent to the Treblinka extermination camp over the course of two months in the summer of 1942. Over 100,000 of the Ghetto’s residents died due to rampant disease or starvation, as well as executions and random killings, even before the Nazis began mass deportations. The death toll among the Jewish inhabitants of the Ghetto, between deportations to extermination camps, Großaktion Warschau, the Warsaw Ghetto Uprising, and the subsequent razing of the ghetto in May 1943, is estimated to be at least 300,000.
