The Warsaw Ghetto Uprising was the 1943 act of Jewish resistance in the Warsaw Ghetto in German-occupied Poland during World War II to oppose Nazi Germany's final effort to transport the remaining ghetto population to the gas chambers of the Majdanek and Treblinka extermination camps.

Majdanek was a Nazi concentration and extermination camp built and operated by the SS on the outskirts of the city of Lublin during the German occupation of Poland in World War II. It had seven gas chambers, two wooden gallows, and some 227 structures in all, placing it among the largest of Nazi concentration camps. Although initially intended for forced labor rather than extermination, it was used to murder people on an industrial scale during Operation Reinhard, the German plan to murder all Polish Jews within their own occupied homeland. In operation from 1 October 1941 to 22 July 1944, it was captured nearly intact. The rapid advance of the Soviet Red Army during Operation Bagration prevented the SS from destroying most of its infrastructure, and Deputy Camp Commandant Anton Thernes failed to remove the most incriminating evidence of war crimes.
