Warsaw Ghetto Uprising Begins Against Nazis

Context

The Warsaw Ghetto was established by German authorities in October 1940 as the largest of the ghettos created in occupied Poland, confining roughly 400,000 Jews into a densely packed 3.3 square kilometer area of Warsaw. Overcrowding, starvation, and disease took a heavy toll even before systematic deportations began under SS and Police Leader Odilo Globocnik and local commander Ludwig Hahn.

In summer 1942, German forces launched the Grossaktion Warsaw, deporting approximately 265,000 residents to the Treblinka extermination camp between July 22 and September 21. This operation, directed by SS-Oberführer Ferdinand von Sammern-Frankenegg, reduced the ghetto population to an estimated 70,000–80,000 survivors. Many residents came to understand that deportation meant almost certain death rather than resettlement.

In response, surviving underground groups formed the left-leaning Jewish Combat Organization (ŻOB) in July 1942 and the right-wing Jewish Military Union (ŻZW). These organizations trained fighters, executed suspected collaborators, and secured limited weapons through contacts with the Polish Home Army (Armia Krajowa). A partial deportation attempt in January 1943 met with armed pushback that forced German authorities to pause operations after only a few thousand removals, spurring further bunker construction and defensive preparations.

What Happened

On April 19, 1943—the eve of Passover—German SS, order police, and Trawniki auxiliary forces under initial command of Ferdinand von Sammern-Frankenegg entered the ghetto to resume deportations to Majdanek and Treblinka. Fighters from the ŻOB and ŻZW, numbering roughly 600 and 400 respectively, were already positioned in buildings, on rooftops, and in prepared posts. They opened fire with pistols, homemade grenades, and Molotov cocktails, forcing the German column to withdraw after suffering casualties on the first day.

Jürgen Stroop replaced Sammern-Frankenegg and shifted tactics, directing systematic burning of buildings and use of artillery to destroy resistance positions and force civilians from underground bunkers. ŻOB commander Mordechai Anielewicz coordinated operations from key sites including the bunker at Miła 18, while other leaders such as Yitzhak Zuckerman, Zivia Lubetkin, and Marek Edelman directed actions across sectors. Civilians supported the fighters by refusing to assemble at collection points and remaining hidden.

The fighting continued for nearly a month as German forces advanced block by block. Resistance persisted from sewers and fortified positions despite the destruction of most structures. Anielewicz and many of his group were killed when the Miła 18 bunker was discovered and destroyed on May 8.

Aftermath

German forces declared the operation complete on May 16, 1943, after blowing up the Great Synagogue of Warsaw as a symbolic finale. According to Stroop’s official report, at least 56,065 Jews were killed or captured during the suppression. The vast majority of those captured were deported to extermination or labor camps, with many later murdered in the November 1943 Operation Erntefest shootings at Majdanek and nearby sites.

The physical ghetto was almost entirely razed, leaving only ruins. The event eliminated the largest remaining Jewish community in occupied Poland and marked the end of organized life in Warsaw’s Jewish quarter.

Legacy

The Warsaw Ghetto Uprising stands as the largest and most sustained single revolt by Jews against Nazi authorities during World War II. It demonstrated that organized armed resistance was possible even under conditions of extreme isolation and limited resources, influencing later uprisings in other ghettos such as Białystok and in camps including Treblinka and Sobibór.

Postwar, the uprising became a defining symbol of Jewish defiance and dignity. Its commemoration on Yom HaShoah in Israel and through memorials worldwide helped shape Holocaust memory around themes of resistance rather than solely victimhood. The event has informed international discussions on human rights, the ethics of resistance under occupation, and the documentation of Nazi crimes through Stroop’s own detailed report, which later served as evidence in postwar trials.
