Perpetrator: Soviet government under Stalin

Victims: Ukrainian peasants

Estimate Source Deaths
Lower scholarly 3.5 million
Central estimate 3.9 million
Higher estimates Up to 7 million

Mechanisms: – Impossibly high grain requisition quotas – Confiscation of all foodstuffs – Blocking of food relief – Internal passport system preventing escape – Blacklisting of villages

Attribution: 1962 official review: 30% natural disasters, 70% policy errors.

Irish Great Famine (1845-1852)

Context: British-ruled Ireland

Victims: Irish peasants

Category Number
Deaths (starvation/disease) 1 million
Emigration 2 million
Population decline (1841-1901) 8.5M to 4.4M

Immediate cause: Potato blight (Phytophthora infestans)

Policy failures: – Continued food exports (75% of farmland produced export crops) – Inadequate relief measures – Workhouse system – Laissez-faire ideology – Trevelyan's statement: “direct stroke of an all-wise Providence”

Part 5: Patterns and Comparisons

Common Features of Genocide

Feature Examples
Dehumanization Jews as “vermin”; Tutsi as “cockroaches”; Armenians as “disease”
Classification/identification Yellow stars; ID cards; population registries
State organization Bureaucratic planning; military involvement
Propaganda Radio, newspapers, speeches inciting hatred
Isolation Ghettos, camps, restricted areas
Denial During and after; destruction of evidence

Warning Signs (Genocide Watch)

  1. Classification
  2. Symbolization
  3. Discrimination
  4. Dehumanization
  5. Organization
  6. Polarization
  7. Preparation
  8. Persecution
  9. Extermination
  10. Denial

Factors Enabling Mass Atrocity

Factor Examples
War/conflict WWI (Armenia), WWII (Holocaust), Liberation war (Bangladesh)
Economic crisis Weimar Germany, 1990s Rwanda
Authoritarian rule Stalin, Mao, Pol Pot, Amin
Colonial structures Congo, Americas, Namibia
International indifference Rwanda, Darfur
Dehumanizing ideology Nazism, Hutu Power, Khmer Rouge

Accountability Comparison

Event Trials Convictions Other
Holocaust Nuremberg + national Thousands Ongoing
Armenia None None Some recognition
Rwanda ICTR + Gacaca 61 (international); 1.9M (domestic) Extensive
Cambodia ECCC 3 Limited
Bosnia ICTY Multiple Ongoing denial
Indonesia None None Official impunity
Congo Free State None None Belgium apology

Part 6: Remembrance and Politics

How Atrocities Are Remembered (or Forgotten)

Event Recognition Level Political Use
Holocaust Near-universal Israel advocacy; “never again” framing
Armenian Contested (Turkey denies) Diaspora advocacy; Turkish politics
Holodomor Growing recognition Ukrainian nationalism; anti-Russia
Native American Limited acknowledgment Indigenous rights movements
Congo Largely forgotten Belgian colonial reckoning
Indonesia Suppressed Remains politically sensitive

The Politics of Death Tolls

Death tolls are often contested for political reasons:

Event Low Estimate High Estimate Political Stakes
Holocaust 5.1M (Hilberg) 6M+ Deniers minimize; memory politics
Holodomor 3.5M 7M+ Ukraine emphasizes; Russia minimizes
Bangladesh 26K (Pakistan) 3M (Bangladesh) Pakistan denial
Armenia 600K 1.5M Turkey denial
Great Leap Forward 15M 55M CCP legitimacy

Conclusion: Lessons and Patterns

What History Shows

  1. Genocides are planned: Not spontaneous violence but organized state policy
  2. Warning signs exist: Classification, dehumanization, preparation are visible
  3. International response often fails: Rwanda, Darfur, ongoing crises
  4. Denial is universal: Every perpetrator state denies or minimizes
  5. Accountability is rare: Most perpetrators face no consequences
  6. Memory is political: How atrocities are remembered serves present purposes

The Scale of Human-Caused Death

Category Estimated Deaths (20th-21st century)
Genocides 15-20 million
Political famines 40-80 million
Political mass killings 10-20 million
Colonial atrocities (ongoing effects) Incalculable

Total deliberate mass death in modern history: Likely exceeds 100 million.
