"German soldiers question Jews after the Warsaw Ghetto Uprising in 1943. In October 1940, the Germans began to concentrate Poland’s population of over 3 million Jews into overcrowded ghettos. In the largest of these, the Warsaw Ghetto, thousands of Jews died due to rampant disease and starvation, even before the Nazis began their massive deportations from the ghetto to the Treblinka extermination camp. The Warsaw Ghetto Uprising — the first urban mass rebellion against the Nazi occupation of Europe — took place from April 19 until May 16 1943, and began after German troops and police entered the ghetto to deport its surviving inhabitants. It ended when the poorly-armed and supplied resistance was crushed by German troops."
