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 Majdanek and Treblinka death camps.

After the Grossaktion Warsaw of summer 1942, in which more than a quarter of a million Jews were deported from the ghetto to Treblinka and murdered, the remaining Jews began to build bunkers and smuggle weapons and explosives into the ghetto. The left-wing Jewish Combat Organization (OB) and right-wing Jewish Military Union (ZW) formed and began to train. A small resistance effort to another roundup in January 1943 was partially successful and spurred Polish resistance groups to support the Jews in earnest.

The uprising started on 19 April when the ghetto refused to surrender to the police commander SS-Brigadefhrer Jrgen Stroop, who ordered the burning of the ghetto, block by block, ending on 16 May. A total of 13,000 Jews were killed, about half of them burnt alive or suffocated. German casualties were probably fewer than 150, with Stroop reporting 110 casualties [16 killed + 1 dead/93 wounded].It was the largest single revolt by Jews during World War II. The Jews knew that the uprising was doomed and their survival was unlikely. Marek Edelman, the only surviving OB commander, said their inspiration to fight was "not to allow the Germans alone to pick the time and place of our deaths". According to the United States Holocaust Memorial Museum, the uprising was "one of the most significant occurrences in the history of the Jewish people".

The Holocaust, also known as the Shoah, was the genocide of European Jews during World War II. Between 1941 and 1945, Nazi Germany and its collaborators systematically murdered some six million Jews across German-occupied Europe, around two-thirds of Europe's Jewish population. The murders were carried out in pogroms and mass shootings; by a policy of extermination through labor in concentration camps; and in gas chambers and gas vans in German extermination camps, chiefly Auschwitz-Birkenau, Bełżec, Chełmno, Majdanek, Sobibór, and Treblinka in occupied Poland.Germany implemented the persecution in stages. Following Adolf Hitler's appointment as chancellor on 30 January 1933, the regime built a network of concentration camps in Germany for political opponents and those deemed "undesirable", starting with Dachau on 22 March 1933. After the passing of the Enabling Act on 24 March, which gave Hitler dictatorial plenary powers, the government began isolating Jews from civil society; this included boycotting Jewish businesses in April 1933 and enacting the Nuremberg Laws in September 1935. On 9–10 November 1938, eight months after Germany annexed Austria, Jewish businesses and other buildings were ransacked or set on fire throughout Germany and Austria on what became known as Kristallnacht (the "Night of Broken Glass"). After Germany invaded Poland in September 1939, triggering World War II, the regime set up ghettos to segregate Jews. Eventually, thousands of camps and other detention sites were established across German-occupied Europe.

The segregation of Jews in ghettos culminated in the policy of extermination the Nazis called the Final Solution to the Jewish Question, discussed by senior government officials at the Wannsee Conference in Berlin in January 1942. As German forces captured territories in the East, all anti-Jewish measures were radicalized. Under the coordination of the SS, with directions from the highest leadership of the Nazi Party, killings were committed within Germany itself, throughout occupied Europe, and within territories controlled by Germany's allies. Paramilitary death squads called Einsatzgruppen, in cooperation with the German Army and local collaborators, murdered around 1.3 million Jews in mass shootings and pogroms from the summer of 1941. By mid-1942, victims were being deported from ghettos across Europe in sealed freight trains to extermination camps where, if they survived the journey, they were gassed, worked or beaten to death, or killed by disease, starvation, cold, medical experiments, or during death marches. The killing continued until the end of World War II in Europe in May 1945.

The European Jews were targeted for extermination as part of a larger event during the Holocaust era (1933–1945), in which Germany and its collaborators persecuted and murdered millions of others, including ethnic Poles, Soviet civilians and prisoners of war, the Roma, the disabled, political and religious dissidents, and gay men.
