Was the 20th Century Really the Most Violent?

That is the question posed and answered by Steven Pinker (Pinker 2011: 193–200), and his answer is likely to startle many people.

First, let us consider the man depicted in this painting below.



You might recognise him already. This is Genghis Khan (c. 1162–1227), and the evidence would suggest that he rivalled the worst 20th century dictators in the number of people killed during his wars of conquest.

Of course, in terms of absolute numbers, no one doubts that the 20th century was the most violent in human history.

Yet immediately one must point out that the 20th century also had a greater population than any previous century. The question “how violent is this war compared to that war?” requires per capita death rates, not absolute numbers.

The table below ranks the most violent episodes in Medieval and Modern human history, and all dates are AD.

The third column (“Est. Death Toll”) shows the estimated death toll in millions, and the fourth column (“Adjusted Death Toll”) shows us what the death toll would have been for any conflict before the 20th century, but adjusted for the 20th century population.

That is to say, if Tamerlane had lived in the 20th century, and his conquests had occurred with the same per capita death rate as they did in his own time, how many people would have died?

What do you notice?
Event | Century | Est. Death Toll* | Adjusted Death Toll*
* both in millions

(1) An Lushan Revolt | 8th | 36 | 429

(2) Mongol Conquests | 13th | 40 | 278

(3) Mideast Slave Trade | 7th–19th | 19 | 132

(4) Fall of Ming Dynasty | 17th | 25 | 112

(5) Fall of Rome | 3rd-5th | 8 | 105

(6) Timur Lenk (Tamerlane) | 4th–15th | 17 | 100

(7) Killing of American Indians | 15th–19th | 20 | 92

(8) Atlantic Slave Trade | 15th–19th | 18 | 83

(9) Second World War | 20th | 55 | 55

(10) Taiping Rebellion 19th | 20 | 40

(11) Mao Zedong | 20th | 40 | 40

(12) British India | 19th | 17 | 35

(13) Thirty Years War | 17th | 7 | 32

(14) Russia’s Time of Troubles | 16th–17th | 5 | 23

(15) Josef Stalin | 20th | 20 | 20

(16) First World War | 20th | 15 | 15

(17) French Wars of Religion | 16th | 3 | 14

(18) Congo Free State | 19th–20th | 8 | 12

(19) Napoleonic Wars | 19th | 4 | 11

(20) Russian Civil War | 20th | 9 | 9

(21) Chinese Civil War | 20th | 3 | 3 (Pinker 2011: 195).

Notes
(1) Some of these atrocities were mostly caused by man-made (or preventable) famine, e.g., the death toll for Mao Zedong and British India.
What is most remarkable is that of the top 10, only the Second World War makes it onto that list, and only at number (9) in terms of per capita death rates.

All the other 10 most violent events of human history did not even occur in the 20th century.

The most murderous events of human history were the An Lushan Revolt in the 8th century AD China, and the Mongol Conquests of the 13th century AD.

The death toll from the Mongol Conquests was very high, and the 20th century equivalent would have been a conflict in which 278 million people died. By contrast, the Second World War killed some 55 million people.

That would make Genghis Khan one of the worst monsters of history, and the eruption of essentially stateless nomads from the Eurasian steppe one of most violent events of human history.

Nor were the Mongols the first such invaders. Sedentary agricultural peoples down through the centuries – in Europe, the Near East and China – have been terrorised by steppe nomads many times in human history: we need only think of the (often stateless) Scythians, Sarmatians, Goths, Huns, Bulgars, Avars, Magyars, Tartars, Cumans, Khazars, Mughuals and Manchus. The wars of such people are remarkably consistent with Pinker’s thesis about higher levels of violence in stateless and tribal societies as compared with state-based societies.

  1. So what's the point? I don't want to meet a violent death. I don't care if violence is defined in proportional or absolute terms. The lesson people have to learn is that violence doesn't JUST "happen" Someone decides to perpetrate violent acts against another. Whatever the reasons they have for doing so. Those reasons need to be closely examined and hopefully rejected. As a population, humans are doing better at this. Today it is widely accepted than there are fewer legitimate reasons for violent behavior than in the past. That is the reason for lower rates of death from violence today. People say no!
    Government is the sole perpetrator of legal violence remaining in our society. It must be watched, controlled and when the time comes stopped by its own population. As happened in the Arab Spring, with The Third Reich, USSR. What was the ultimate "good" that came from all that violence? I suspect very little. It was mostly a bunch of groupies blindly following a violent leader to their own demise. We should learn the same lesson regarding our own politicians and experts.

    1. "Government is the sole perpetrator of legal violence remaining in our society."

      That is a tautology.

      In fact: that the government has a monopoly on force is a good thing. It keeps the level of private sector violence right down.

      Also, you appear to have missed the point of the post: was the 20th century the most violent?

  2. Wow, I came to a similar conclusion about the 13th century being the most violent in history. I even wrote an article about it for Yahoo.

  3. Why not count some of the relentless Muslim conquests?

    1. You could certainly include them, but scholars need a good estimate of the estimated death toll to compare them with others on the list.

      E.g, the Muslim slave trade was very brutal.

  4. Do you also notice that the various slave trades and certain other events in the top half of the list each occurred over a number of centuries?

    And that out of the 21 events listed, the majority happened in the 19th and 20th Centuries? 7 in the 20th Century.

    And if we total the counts from those beginning in the 19th Century until now, we get at least 229 million in the last 200 years or so. This is ignoring countless other events throughout history, I realize, but... let's not pretend that some really horrible violence isn't continuing to happen. We're just as 'at risk' as ever.

    1. Moreover, what of the dozens of Cold War proxy fights that added up to nearly 50 million killed in the Third World in the last half of the 20th century? The list above is of the big categorically named "events." But most of the 1951-2000 deaths were in small "events" that would never make this list.
