Question 1

Which country has killed the most people in history?

Accepted Answer

By total state-caused deaths, China under Mao Zedong ranks among the highest in history with an estimated 35–45 million deaths — primarily from the Great Leap Forward famine (1958–62), which killed 15–55 million through forced collectivization policies. The Mongol Empire under Genghis Khan killed an estimated 40 million people (~10% of the world's population) through military conquests. Nazi Germany killed 12–17 million through the Holocaust and WWII operations. The Soviet Union under Stalin caused 6–20 million deaths. Rankings depend on methodology and time period.

Question 2

How many people did Genghis Khan kill?

Accepted Answer

Genghis Khan and his Mongol Empire successors (1206–1368) are estimated to have killed approximately 40 million people — roughly 10% of the world's population at the time. Major massacres include Baghdad (1258, ~1–2 million killed), Merv (~700K–1.3 million), and Nishapur (~1.7 million). Cities that resisted Mongol conquest were systematically depopulated.

Question 3

How many people died in the Great Leap Forward?

Accepted Answer

Mao Zedong's Great Leap Forward (1958–62) caused the deadliest famine in human history. Estimates range from 15 million (conservative) to 55 million (Frank Dikötter). The scholarly consensus centers around 30–36 million deaths (Judith Banister, Yang Jisheng). The famine was caused by forced agricultural collectivization, grain confiscation, and the suppression of reporting on starvation.

Question 4

What was the deadliest genocide in history?

Accepted Answer

The Holocaust (1941–1945) is the most documented genocide: 6 million Jews plus 5–6 million others (Roma, disabled, Soviet POWs, Slavic civilians) were systematically murdered by Nazi Germany. By total deaths, the Mongol conquests killed more people but over a longer period. The Rwandan Genocide (1994) was the fastest: ~800,000 killed in 100 days.

Question 5

Which countries have committed genocide?

Accepted Answer

Countries and empires responsible for recognized or widely-documented genocides include: Nazi Germany (Holocaust), Ottoman Empire (Armenian, Assyrian, Greek genocides), Cambodia (Khmer Rouge), Rwanda (1994 genocide), Bosnia/Serbia (Srebrenica), Myanmar (Rohingya), Sudan (Darfur), Pakistan (1971 Bangladesh), Indonesia (East Timor), and Imperial Germany (Herero and Nama). Colonial powers including Belgium (Congo), Spain, Portugal, and Britain also caused mass deaths through colonial exploitation.
