The Warsaw Ghetto Uprising (; ; ) was the 1943 act of Jewish resistance that arose within the Warsaw Ghetto in German-occupied Poland during World War II, and which opposed Nazi Germany's final effort to transport the remaining Ghetto population to Treblinka extermination camp. The uprising started on 19 April when the Ghetto refused to surrender to the police commander SS-Brigadeführer Jürgen Stroop, who then ordered the burning of the Ghetto, block by block, ending on 16 May. 13,000 Jews died, about half of them burnt alive or suffocated. German casualties are not known, but were not more than 300. It was the largest single revolt by Jews during World War II.
