Stages of the Holocaust and Jewish Resistance
The Holocaust was the state-sponsored, systematic persecution and murder of approximately six million European Jews by Nazi Germany and its collaborators between 1933 and 1945. Understanding how this genocide unfolded in stages, and how Jews resisted at every phase, is central to grasping the Holocaust's lasting impact on Jewish identity.
Stages of the Holocaust
Ghettoization and Concentration Camps
Ghettoization was the forced relocation of Jewish populations into designated, sealed-off areas within cities. Jews were stripped of their freedom of movement and cut off from resources.
- Major ghettos included Warsaw (the largest, holding over 400,000 people), Łódź, and Theresienstadt
- Conditions were defined by extreme overcrowding, poor sanitation, and grossly inadequate food and medical supplies. Disease and starvation killed tens of thousands before deportations even began.
Concentration camps were established to imprison and exploit Jews, political prisoners, Roma, and other groups the Nazis targeted.
- Prisoners endured forced labor, medical experiments, and arbitrary violence from SS guards
- Major concentration camps included Dachau (one of the first, opened in 1933), Buchenwald, and Mauthausen
- These camps had staggering death rates from disease, exhaustion, and outright murder, though they differed from the extermination camps discussed below
Mass Shootings and the Final Solution
Before the gas chambers, mass shootings were the Nazis' primary method of killing Jews in Eastern Europe.
- Einsatzgruppen (mobile killing units) followed the German army's advance into the Soviet Union beginning in 1941, systematically shooting Jews and other targeted groups
- These units killed over 1.5 million people, most of them Jews
- Notable massacres include Babi Yar near Kyiv, Ukraine (over 33,000 Jews killed in two days in September 1941) and Rumbula near Riga, Latvia (approximately 25,000 killed in November-December 1941)
The shift from mass shootings to industrialized killing was formalized at the Wannsee Conference in January 1942. High-ranking Nazi officials met to coordinate the logistics of the "Final Solution," the plan to systematically exterminate all European Jews. This conference did not originate the idea of genocide, but it organized the bureaucratic machinery to carry it out across all of occupied Europe.
Extermination camps were then established with the sole purpose of mass murder:
- Camps such as Auschwitz-Birkenau, Treblinka, Sobibór, Bełżec, Chełmno, and Majdanek used gas chambers (often employing Zyklon B poison gas) and crematoria to kill and dispose of victims on an industrial scale
- At Treblinka alone, approximately 900,000 Jews were murdered, most within hours of arrival
- This represented something historically unprecedented: the industrialization of mass murder
The liberation of the camps by Allied forces in 1944-1945 revealed the full scope of the atrocities. Survivors' testimonies and the physical evidence shocked the world. The Nuremberg Trials (1945-1946) prosecuted major Nazi perpetrators and established the principle that individuals bear responsibility for crimes against humanity, even when acting under government orders.
Jewish Resistance During the Holocaust

Armed Resistance
A persistent myth holds that Jews went passively to their deaths. In reality, Jewish resistance took many forms under conditions that made any opposition extraordinarily dangerous.
Ghetto and camp uprisings:
- The Warsaw Ghetto Uprising (April-May 1943) was the largest single act of Jewish armed resistance. Roughly 750 fighters with limited weapons held off German forces for nearly a month before the Nazis razed the ghetto.
- The Sobibór revolt (October 1943), led by Soviet-Jewish POW Alexander Pechersky and other Jewish prisoners, resulted in the escape of about 300 inmates. The Nazis subsequently dismantled the camp.
- The Sonderkommando uprising at Auschwitz (October 1944) saw Jewish prisoners forced to work in the crematoria attack SS guards and destroy one crematorium, using explosives smuggled by female prisoners from a nearby munitions factory.
Partisan warfare:
- Jewish partisans operated in forests and rural areas across Eastern Europe, sabotaging German supply lines, attacking military targets, and sheltering Jews fleeing persecution
- The Bielski partisans in Belarus, led by the Bielski brothers, built a forest community that sheltered over 1,200 Jews by war's end, making it one of the largest rescue operations by Jews themselves
- The Jewish Fighting Organization (ŻOB) organized armed resistance within the Warsaw Ghetto
Spiritual and Cultural Resistance
Spiritual resistance meant refusing to let the Nazis destroy Jewish identity, faith, and culture. Under conditions designed to dehumanize, maintaining these things was itself an act of defiance.
- Jews in ghettos and camps organized clandestine prayer services, religious study groups, and holiday observances
- Secret schools were established so children could continue their education, preserving knowledge and cultural continuity
- Small daily acts of resistance, like sharing scarce food, caring for the sick, creating art, and maintaining personal dignity, sustained community bonds under unbearable conditions
One of the most remarkable cultural resistance efforts was the Oyneg Shabes archive in the Warsaw Ghetto, organized by historian Emanuel Ringelblum. A network of writers, scholars, and ordinary people documented daily life, Nazi atrocities, and Jewish responses. The archive was buried in milk cans and metal boxes before the ghetto's destruction. Parts were recovered after the war and remain one of the most important primary sources on the Holocaust.
Collaborators and Bystanders in the Holocaust
Collaborators
Collaborators were individuals, organizations, or governments that cooperated with the Nazi regime in persecuting and murdering Jews and other targeted groups. The Holocaust could not have been carried out on such a massive scale without local collaboration.
- Local police forces and auxiliaries in occupied countries aided in rounding up, deporting, and executing Jews. Examples include the French Milice and the Ukrainian Auxiliary Police.
- These collaborators had local knowledge that made it far easier to identify and apprehend Jews. Motivations ranged from ideological antisemitism to opportunism to fear of punishment.
State-level collaboration:
- The Vichy government in France, led by Marshal Philippe Pétain, enacted its own anti-Jewish laws and cooperated in deporting Jews to extermination camps
- The Ustaše regime in Croatia, led by Ante Pavelić, established concentration camps and carried out mass killings of Jews, Serbs, and Roma
Collaboration also took everyday forms. Individuals denounced hidden Jews to authorities, profited from the seizure of Jewish businesses and property, or looted Jewish homes. Informants who reported Jews' whereabouts directly contributed to arrests and deportations.

Bystanders
Bystanders were individuals or nations that witnessed the Holocaust but did not actively intervene.
- The majority of civilians in Nazi-occupied territories did not resist or protest the persecution of their Jewish neighbors. Fear of reprisals, a sense of powerlessness, indifference, and ingrained antisemitism all played roles.
- The normalization of anti-Jewish measures happened gradually, making each escalation easier to accept or ignore.
The international community's passivity is covered in more detail below, but the broader lesson of bystander behavior remains significant for understanding the Holocaust. The genocide demonstrated how complicity and apathy can enable mass atrocities, and it raises difficult questions about the moral obligations of individuals and societies when they witness injustice.
International Response to the Holocaust
Pre-War Responses and the Jewish Refugee Crisis
The international response to the Holocaust was marked by indifference, restrictive policies, and missed opportunities to save lives.
- Before World War II, many countries severely limited Jewish immigration. The United States maintained strict national-origin quotas that kept Jewish refugee admissions far below demand.
- The Évian Conference (1938), convened by President Roosevelt to address the refugee crisis, ended with almost no country willing to accept more Jewish refugees. The Dominican Republic was the only nation to make a significant offer.
- The MS St. Louis (1939), carrying over 900 Jewish refugees, was turned away by Cuba, the United States, and Canada. Forced to return to Europe, roughly a quarter of its passengers eventually died in the Holocaust.
- The Bermuda Conference (1943), held by the U.S. and U.K. to discuss the refugee crisis, produced no concrete rescue plans. It focused on postwar resettlement rather than immediate action.
Responses During the War
Allied governments received credible reports of the genocide but did not prioritize rescue efforts.
- The Allies did not bomb the Auschwitz-Birkenau extermination camp or its railway lines, despite having the capability by 1944. Military leaders debated feasibility and effectiveness, but ultimately prioritized other targets. This decision remains one of the most debated aspects of the Allied response.
- The War Refugee Board, established by the U.S. in January 1944, did facilitate the rescue of tens of thousands of Jews through diplomatic pressure, financial support, and coordination with neutral countries. But it was created late in the war, after millions had already been killed.
- Notable individual rescuers connected to the Board included Raoul Wallenberg, a Swedish diplomat who issued protective passports to tens of thousands of Hungarian Jews, and Hiram Bingham IV, a U.S. diplomat who provided visas and assistance to refugees in France.
The inadequacy of the international response stemmed from competing military priorities, bureaucratic inertia, lack of public pressure, and, in many cases, antisemitism within Allied governments themselves. The Holocaust exposed deep failures in international law and institutions, directly fueling postwar efforts like the Universal Declaration of Human Rights (1948) and the UN Genocide Convention (1948) to create new frameworks for preventing and responding to mass atrocities.
