Holocaust
How Many Events in History Can Be Classified as a Holocaust?
The word “holocaust” is most commonly associated with the Nazi genocide of Jews during World War II. Historically, however, the term refers more broadly to large-scale destruction or mass killing, and many scholars use it interchangeably with genocide when describing systematic, state-sponsored extermination of civilian populations.
Throughout history, multiple events meet these criteria. What often varies is how many people were killed, how deaths are counted, and whether international organizations—such as the International Committee of the Red Cross (ICRC)—were able to document the atrocities as they occurred.
Major Historical Genocides and Estimated Death Tolls
1. The Holocaust (1941–1945)
Perpetrator: Nazi Germany
Victims: Jews, Roma, disabled individuals, Poles, Soviet POWs, LGBTQ+ people, and political dissidents
Estimated Deaths:
~6 million Jews
~11–17 million total victims
The Holocaust is the most extensively documented genocide in history. The ICRC was directly involved during WWII, particularly in prisoner-of-war monitoring, and postwar investigations align with the widely accepted figures.

Debate: There is no credible academic debate about whether the Holocaust occurred. Variations relate only to whether non-Jewish victims are included in the total count.
2. Armenian Genocide (1915–1923)
Perpetrator: Ottoman Empire
Victims: Armenians, Assyrians, Greeks
Estimated Deaths: ~1.5 million Armenians
The Red Cross and Red Crescent societies were active in refugee relief during this period, but comprehensive death records were never fully compiled.

Debate: Turkey disputes both the term “genocide” and the death toll, while most historians accept the ~1.5 million figure.
3. Rwandan Genocide (1994)
Perpetrator: Hutu extremist militias
Victims: Tutsis, moderate Hutus, Twa
Estimated Deaths: ~800,000 in approximately 100 days
The ICRC was one of the only international organizations operating continuously during the genocide, documenting mass killings and humanitarian collapse.

Debate: Estimates range from 500,000 to over 1 million depending on inclusion of indirect deaths.
4. Cambodian Genocide (1975–1979)
Perpetrator: Khmer Rouge regime
Victims: Intellectuals, ethnic minorities, political opponents
Estimated Deaths: 1.5–2 million
The ICRC documented mass starvation, forced labor, and executions, though access was limited.

Debate: Death estimates vary due to lack of population data and regime secrecy.
5. Holodomor (1932–1933)
Perpetrator: Soviet government under Joseph Stalin
Victims: Ukrainian peasants
Estimated Deaths: 3.5–7 million
The ICRC was denied access to Soviet Ukraine, meaning no official Red Cross death count exists.

Debate: Scholars disagree on whether the famine constituted intentional genocide or criminal state negligence.
6. Nanjing Massacre (1937–1938)
Perpetrator: Imperial Japanese Army
Victims: Chinese civilians and POWs
Estimated Deaths: 200,000–300,000
The ICRC-supported Nanjing Safety Zone, which documented atrocities and saved tens of thousands of civilians.

Debate: Disputes remain over geographic boundaries and classification of deaths.
7. Bosnian Genocide (1992–1995)
Perpetrator: Bosnian Serb forces
Victims: Bosniak Muslims and Croats
Estimated Deaths: ~100,000
Srebrenica Massacre: 8,000+ men and boys
The ICRC maintained extensive field operations, especially related to missing persons.

Debate: Minimal regarding Srebrenica; broader war deaths vary by methodology.
8. Indigenous Peoples of the Americas (16th–19th Century)
Perpetrators: European colonial powers and later U.S. policies
Victims: Indigenous populations across North and South America
Estimated Deaths: 10–100 million
The Red Cross did not exist during early colonization, so no official records exist.

Debate: Major disagreement over how many deaths were caused by disease versus violence and forced displacement.
Why Death Toll Numbers Are Debated
Incomplete or destroyed records
Restricted access for humanitarian organizations
Political denial or revisionism
Indirect deaths from famine, disease, and displacement
The ICRC generally avoids issuing definitive death totals, focusing instead on humanitarian response, missing persons, and civilian protection.
Conclusion
There is no universally agreed-upon number of historical events that qualify as “holocausts.” What is clear is that multiple genocides meet the criteria of systematic mass extermination, and the true human cost is often higher than any recorded figure.
