The Mongol Empire

He couldn't read, but he wrote a legal code that governed more people than Rome ever did

Think of one man, Genghis Khan, riding out of the steppe and putting all of Eurasia to the sword. The gates of Vienna. The House of Wisdom in Baghdad. The Yangtze river.

He died in August of twelve twenty seven, probably on campaign against the Xi Xia kingdom.

The Mongol army did not reach Hungary and Poland until twelve forty one, fourteen years after he was gone. Baghdad fell in twelve fifty eight, to his own grandson, thirty one years after he was gone. The conquest of southern China did not finish until twelve seventy nine, fifty two years after he was gone, under another grandson.

The empire everyone pictures inside one lifetime took three generations to build. The man whose name it carries saw less than half of it happen.

Scene 1The cangue

Look at the boy first, not the khan. His name was Temüjin. When he was nine, Tatars poisoned his father, Yesügei, and the clan that owed the family loyalty abandoned them on the steppe.

His half brother Begter challenged his authority. Temüjin killed him.

He was captured by the Tayichi'ud and forced to wear a cangue, a wooden collar locked around his neck, until he escaped with help from a family that sheltered him at the risk of their own lives.

Every policy that followed traces back to this. The destruction of tribal aristocracies. The promotion of commoners by merit. The loyalty he demanded from everyone under him.

He did not inherit power. He built it from nothing, and he rebuilt Mongol society so that no one could be abandoned the way he had been.

Scene 2The Onon river, 1206

In twelve oh six, a kurultai, a gathering of Mongol tribal chiefs, met on the banks of the Onon river and proclaimed Temüjin as Genghis Khan, universal ruler. He was about forty four.

He had spent twenty years unifying the Mongol, Tatar, Merkit, Naiman and Kereit tribes, through conquest, through strategic marriages, through blood brotherhood, and through the destruction of rival aristocracies.

The confederation he had built held perhaps one million people. Within sixty years his grandsons would rule from the Pacific Ocean to the Danube.

This is what Genghis Khan is recorded as saying was a man's greatest joy.

Attributed to Genghis Khan · Recorded by Rashid al-Din, Compendium of Chronicles · c. 1300

“The greatest joy a man can know is to conquer his enemies and drive them before him, to ride their horses and take away their possessions, to see the faces of those who were dear to them bedewed with tears, and to clasp their wives and daughters in his arms.”

Scene 3Otrar, 1219

The governor of Otrar executed a caravan of Mongol trade envoys. Under Mongol law, envoys were inviolate.

Genghis Khan invaded with somewhere between a hundred thousand and a hundred fifty thousand troops.

Otrar was razed. Bukhara was burned. Samarkand surrendered and was sacked anyway. Merv, Nishapur and Herat were destroyed so thoroughly that chroniclers counted the skulls in pyramids.

To Genghis Khan, the governor's act was not a local crime. It was, by Mongol law, a declaration of war as clear as any that had ever been issued.

Ibn al-Athir wrote his history from Mosul, a city the Mongols never took.

Ibn al-Athir · Al-Kamil fi al-Tarikh · 1231

“In the space of a single year they seized the most populous, the most beautiful, and the best cultivated part of the earth whose inhabitants excelled in character and urbanity. This is a thing the like of which had not been heard.”

Scene 4Karakorum, 1254

A Franciscan friar named William of Rubruck, sent by Louis the Ninth of France, reached the Mongol capital of Karakorum in twelve fifty four.

He found Nestorian Christian churches, Buddhist temples and mosques standing on the same streets.

In the khan's palace, a Parisian goldsmith named Guillaume Boucher, captured by Mongol forces in Hungary, had built a silver fountain that dispensed four different drinks through four lion heads.

This was not tolerance in the modern sense. It was imperial pragmatism. But on the street, the effect was the same.

Scene 5Yamen, 1279

Kublai Khan's conquest of the Song dynasty took twenty years and ended at sea.

At the naval Battle of Yamen, the last Song emperor was an eight year old boy. When the battle was lost, his minister jumped into the water carrying the boy on his back.

Both of them drowned. China was reunified under foreign rule for the first time.

Five accounts

Five accounts of one empire, and the same conquest reads differently depending on which side of it you were born on.

  1. The Mongol court
  2. The Chinese court
  3. The Persian world
  4. The Russian principalities
  5. The revisionist argument

The turn

And here is what each one cannot hold at the same time as its own case.

  1. Mongol Imperial

    The Mongol court's account calls the killing a consequence rather than a goal, and it says nothing about the forced population transfers, the enslavement, or the wars its own descendants fought each other over succession.

    From the record
    Scale of civilian massacres in Khwarezmia, northern China, and elsewhere
    Forced population transfers and enslavement of conquered peoples
    Environmental devastation (irrigation systems destroyed, farmland returned to steppe)
    Internal succession crises and fratricidal wars among Genghis Khan''s descendants
  2. Chinese / Jin-Song

    The Chinese account's own numbers are the strongest evidence in this episode, and it says little about the Chinese officials and merchants who served the Yuan willingly, or the cultural flourishing the Yuan patronized alongside the hierarchy.

    From the record
    Mongol administrative innovations adopted by subsequent Chinese dynasties
    Cultural flourishing under Yuan patronage, including the development of Chinese opera (zaju)
    Chinese merchants and officials who served the Yuan willingly and profitably
    Kublai Khan''s genuine engagement with Chinese culture, Buddhism, and governance philosophy
  3. Persian / Islamic

    The Persian account is written by a man on the empire's payroll, and it says less about the Ilkhanate's later conversion to Islam, or the Persian renaissance that the caliphate's own collapse helped enable.

    From the record
    Mongol religious tolerance that allowed Islam to flourish under Ilkhanate rule
    Ilkhanate conversion to Islam and patronage of Islamic learning
    Persian cultural renaissance enabled by the caliphate''s collapse
    Mongol trade protection that benefited Muslim merchants across Eurasia
  4. Russian

    The Russian account calls two centuries a yoke, and it says little about the Russian princes who collaborated with the Horde profitably, or the Orthodox Church, which the Horde exempted from tribute entirely.

    From the record
    Russian princes who collaborated with the Horde willingly and profitably
    Trade and cultural exchange that continued during Mongol suzerainty
    Orthodox Church''s privileged status under Mongol rule, exempt from taxation and tribute
    Russian adoption of Mongol military, administrative, and fiscal practices
  5. Revisionist / Connective

    And the revisionist case, built on postal stations and trade routes, is the one least willing to sit with its own conclusion: forty million dead cannot be balanced against a network, no matter how well the network worked.

    From the record
    40 million dead cannot be balanced against trade routes and postal stations
    Revisionist framing risks minimizing the experience of conquered populations
    Mongol "tolerance" coexisted with systematic massacre, enslavement, and forced population transfer
    Successor states'' descent into fragmentation, civil war, and their own atrocities

Close

Genghis Khan's face is on Mongolian currency now, and his name is on the airport at Ulaanbaatar.

Fifty four kilometers east of the capital, a stainless steel statue of him on horseback stands forty meters tall.

In China, he is classified as a Chinese emperor, the founder of a legitimate dynasty. In Iran, Iraq and Afghanistan, he remains a byword for destruction.

A two thousand three genetic study found that sixteen million men alive today carry a Y chromosome lineage traced to his family line.
