QatwanBattle
A Buddhist steppe army destroyed the Seljuk sultan Sanjar outside Samarkand, which made Transoxiana tributary to a non-Muslim power for the first time since the conquests and reduced the Karakhanids and Khwarazm to vassals. Reports of a great non-Muslim king defeating a Muslim empire in the east reached Europe soon afterwards and are generally thought to lie behind the Prester John story.

Pusuwan killed by arrowsSuccession crisis
The empress Pusuwan, ruling in her own name as gurkhan for fourteen years, had her own husband killed to clear the way for her lover - and was killed in turn, along with him, when the dead man's father, the dynasty's most senior surviving general, surrounded the palace with troops rather than accept it. The throne passed without further crisis to her nephew Zhilugu, confirming that the line the conquest generation's loyalty actually protected was Yelü Dashi's own descent, not the sex of whoever currently held it - a second woman had now ruled the empire in her own right, after Yelü Dashi's own widow had done the same as regent a generation earlier.

A Naiman prince who had taken refuge here after the Mongols broke his own people usurped the throne, and then did the one thing his predecessors never had: he persecuted his Muslim subjects, closing mosques and forcing conversions. Seven years later the population of the Tarim oases treated an approaching Mongol army as a deliverance.

Jebe takes the realm; Kuchlug is hunted downCatastrophe
A Mongol army under Jebe advanced under instructions to proclaim the restoration of religious freedom, and the Tarim oasis populations, faced with a choice between a Buddhist persecutor and a pagan army, largely did not resist it. Kuchlug was hunted into the Pamirs and killed, and the empire ended without a battle worth the name - destroyed by a ruler who finally asked something of subjects it had spent eighty years governing by asking nothing, then finished off by an army those same subjects preferred to him.

A dynasty that walked west
formationDrafted from Biran, Cambridge Studies in Islamic Civilization (2005)
The Liao were the Khitan dynasty that ruled the northern Chinese frontier for
two centuries under two administrations at once — one for the steppe, one for
the settled prefectures. In 1125 the Jurchen destroyed it and the Jin took its
place.
Yelu Dashi was a member of the Liao imperial clan who had passed the Chinese
examinations. When the state collapsed he did not surrender. He rode north-west
with a couple of hundred followers, gathered what Khitan garrisons and allied
tribes remained on the steppe frontier, and kept going — across Mongolia, past
the Uyghurs of the Tarim, into the Semirechye. In 1134 he took Balasaghun from
the eastern Karakhanids, whose ruler had invited him in to deal with unruly
Qarluq and Qangli tribes and discovered he had invited in a state.

What he founded there is one of the odder objects in medieval Eurasia. It was a
Chinese dynasty. The rulers took the title gurkhan, universal khan, but also
Chinese reign names; the chancery worked in Chinese as well as Persian; the
coinage was struck in Chinese form; the dynastic name they used of themselves
was still Liao. Two thousand miles from the nearest Chinese-speaking
administration, ruling a Muslim, Turkic and Persian-speaking population that
had no reason to be impressed by any of it, they kept the whole apparatus.
It is a state that turns up constantly in other people's histories as the power
in the background. The Karakhanids, the first Turkish Muslim dynasty, spent
their last seventy years collecting taxes for it. The Khwarazmshahs made their
empire by throwing its suzerainty off. It is the thing the Ghurids and the
Chagatai inheritance both keep gesturing at, and it is almost never described in
its own right.
Two hundred horsemen
expansionDrafted from Bretschneider, Mediaeval Researches from Eastern Asiatic Sources, volume I (1888)
The Liao dynastic history contains a short account of the man who refounded it
two thousand miles away, and Bretschneider translated it in full. It is the
Qara Khitai founding as told by the Chinese historians of the state Yelü Dashi
walked out of, and it is better than any summary of it.
The man
He was a descendant in the eighth generation of Tai-tsu. He was well versed in
the literature of the Liao, as well as in that of the Chinese; and besides
this he was a clever horseman and skilful archer. In 1115 he received the
degree of shi, and was admitted a member of the Hanlin academy.
A Khitan prince of the imperial line with a Chinese doctorate and a seat in the
national academy, who could also shoot from the saddle. That combination is the
whole of what he did next.
The answer to the emperor
When the Jurchen broke the Liao, the emperor Tianzuo abandoned his throne and
took to roving about. Dashi assembled the dignitaries and put a prince of the
imperial family on the throne instead. The emperor, when he heard, had the
regent put to death and reprimanded Dashi for raising a rival while the
legitimate emperor was still alive.
Dashi answered him:
Even at the time when the empire was still in full vigour, your majesty had
not been able once to repulse the enemy, but had fled far away, abandoning the
people in their calamities; and had I then placed Shun on the throne, the
reigning family would still have been descendants of our ancestor Tai-tsu. Has
it not been the more dignified course now thus to act, instead of imploring
the enemy for mercy?
To this the emperor had nothing to reply. He entertained Ta-shi with a feast and
pardoned him.
Dashi did not feel safe. He killed two of the court dignitaries, declared
himself sovereign, and left by night at the head of two hundred well-armed
horsemen, heading north.
Khitan horsemen, in a detail of *Returning from a Hunt*, attributed to Hu Gui of the tenth century.

What two hundred horsemen accumulate
Three days out, across the Etsina river, an Ongut chief gave him four hundred
horses, twenty camels and about a thousand sheep. He went on west to a city
called Ketun and rested, and there he assembled the chiefs of seven cities and
eighteen tribes, whose names the Liao history lists.
They raised more than ten thousand horsemen. He appointed officers and armed
them.
In the second month of 1121 he sacrificed a black bull and a white horse to
heaven, to earth and to his ancestors, put his troops in order and set out west.
The letter to the Uyghurs
Before he moved he had written to the Uyghur king, and the letter is a small
masterpiece of the diplomatic use of history.
He reminded the king that his own ancestor, the first Liao emperor, had passed
through Uyghur country and sent word to the king's ancestor: do you still
cherish the remembrance of your ancient country? I shall occupy it for you if
you wish to return. The Uyghur had thanked him and declined, saying his people
had been away more than ten generations, were quite happy where they were, and
had no desire to go back.
This proves that we have been for a long time on good terms with your people.
Therefore: I intend to advance west, I ask permission to pass through your
country, do not entertain suspicion.
The king came out to meet him, spent three days entertaining him, gave him six
hundred horses, a hundred camels and three thousand sheep, handed over sons and
grandsons as hostages, declared himself a vassal, and escorted him to the
border of his realm.
That exchange cost nothing and bought a safe corridor, remounts and a client —
using an offer his great-great-grandfather had made three hundred years earlier
and which had been refused.
Ten thousand li
From there, the history says, he vanquished everyone he met and kept the peace
with those who surrendered voluntarily, and the army advanced ten thousand li,
overthrowing kingdoms and taking camels, horses, cattle, sheep and goods beyond
counting.
At Samarkand he met the combined army of all the western kingdoms, a hundred
thousand men. What he said to his troops before it is the last thing in the
Chinese account worth quoting, and it is a professional's assessment:
We see before us a numerous host, but it wants an able commander. When they
are attacked in front, the rear will fail to come to the rescue, and there can
be no doubt our army will gain the victory.
He split into three: twenty-five hundred against the right flank, twenty-five
hundred against the left, and the main body at the centre, all going in
together. The enemy army was destroyed, and for ten li the ground was covered
with bodies.
He rested at Samarkand for ninety days.
The day Transoxiana stopped being Muslim-ruled
peakDrafted from Biran, Cambridge Studies in Islamic Civilization (2005)
In September 1141, on the Qatwan steppe north of Samarkand, the Qara Khitai
destroyed the army of Sanjar, the last great Seljuk sultan. It was the heaviest
defeat any Muslim power suffered before the Mongols, and it is why this dynasty
turns up so often as somebody else's overlord.
The consequences were immediate and structural. Transoxiana — Bukhara,
Samarkand, the country the Samanids and Karakhanids had made — became tributary
to a non-Muslim power for the first time since the Arab conquests. The
Karakhanids continued to reign and began to remit. The Khwarazmshahs became
tributaries too and stayed that way for two generations. Seljuk authority east
of Khurasan never recovered.
The other consequence happened in Europe and is one of the strangest in
medieval history. Word travelled west that a great king from the far east, not a Muslim,
had destroyed a Muslim empire in a huge battle beyond Persia. Within a few
years chroniclers in the Latin kingdoms were reporting a Christian priest-king
in the east — Prester John — who would come to the aid of the Crusader states,
and the letters and expectations attached to that figure ran for four hundred
years. The scholarship generally traces the story to news of Qatwan.
What the victory did not produce is an occupation. The Qara Khitai took
tribute, kept a resident to collect it, left the local dynasties on their
thrones, and did not garrison the cities or interfere with their religion. That
is the subject of the next chapter, and it is the reason this empire is
remembered by its subjects less bitterly than almost anyone else who beat them.
The empress who ruled for her son
contractionDrafted from Bretschneider, Mediaeval Researches from Eastern Asiatic Sources, volume I (1888)
Yelü Dashi died in 1135, twenty years into the empire he had built by
walking his people three thousand miles west rather than surrender to
the Jin. His own son Yilie was not yet of age, and the Liao shi records
what happened next without treating it as anything unusual: the widowed
empress took the regency, ruled the empire in her own name for seven
years, and handed it to her son only when he was old enough to want it.
Tabuyan
The empress, named Tabuyan and given the Chinese title Kan tien huang
hou, governed under her own reign-name, Xian Qing, from 1135 until
1142. The Liao shi says nothing about her policies in the detail it
gives Yelü Dashi's own campaigns, which is itself a kind of evidence:
a seven-year regency that produced no crisis worth narrating is a
regency that worked. The empire she handed over was intact, still
collecting tribute from the Khwarazmian shahs and the Kara-Khanid
princes Qatwan had made vassals, with no successor's legitimacy
seriously questioned when Yilie finally took the throne himself in
1142.
Yilie's own reign
Yilie ruled for thirteen years under the reign-name Shao Xing, long
enough to order a census of his own empire - eighty-four thousand five
hundred families counted across the whole of it, the only such figure
the Chinese sources preserve for the Qara Khitai at any date. He died
in 1155 and was canonised, in the Chinese fashion his dynasty had kept
even three thousand miles from where it was first used, as Renzong.
His own son was still a minor. For the second time in twenty years,
the throne of an empire built by conquest passed not to a man but to a
woman ruling in her own name - this time not a widow, but Yilie's own
younger sister.
Killed by arrows
contractionDrafted from Bretschneider, Mediaeval Researches from Eastern Asiatic Sources, volume I (1888)
Pusuwan held the Qara Khitai throne for fourteen years, longer than
either of the two emperors she ruled between, and the Liao shi records
her downfall in as much detail as it gives any single event in the
dynasty's whole reign in the west - because the men who finally killed
her were the same family that had made her empire's conquests possible
in the first place.
The regent
When Yilie died in 1155 leaving a son too young to rule, the regency
passed to his own younger sister, Pusuwan, who took the title Chengtian
Taihou and reigned under her own era-name, Chongfu, for fourteen
years - the longest single tenure of anyone who ever held the Qara
Khitai throne apart from Yelü Dashi himself. She had married Xiao
Duolu, son of Xiao Wa-li-la, the general who had led Yelü Dashi's own
cavalry divisions at the founding of the empire in Central Asia and
whose family's loyalty had underwritten every gurkhan's authority
since.
The affair the general would not tolerate
Pusuwan took her husband's own younger brother, Pugu Dishali, as a
lover, and when the affair threatened exposure she had her husband
Xiao Duolu murdered to clear the way - after first, with what the
sources treat as a particularly pointed insult, granting him the
honorary title Prince of Dongping. It was a miscalculation. Xiao
Wa-li-la, the murdered man's own father and the dynasty's most senior
surviving general, surrounded the palace with troops rather than accept
the killing of his son. Pusuwan and her lover were both shot to death
with arrows.
What survived her
The dynasty did not merely survive the killing of a reigning gurkhan by
its own senior general - it settled immediately, without a further
succession crisis, on Yilie's second son, Zhilugu, who took the throne
under the era-name Tianxi and, by the Liao shi's own count, held it for
the longest reign of any Qara Khitai ruler after the founder - the
Chinese and Persian chronicles differ by several years on exactly when
that reign ended, which is a dating quarrel rather than a competing
account of the reign itself. What Xiao Wa-li-la's intervention actually
protected was not one woman's authority but the principle that had let
two of them hold it in the first place: that the throne belonged to
Yelü Dashi's own bloodline, male or female, regent or empress, and that
the loyalty the conquest generation owed it did not depend on the sex
of whoever currently held it. Zhilugu's own reign would end
differently - not at the hands of a general defending the dynasty, but
at the hands of a refugee it had sheltered.
How to rule what you cannot outnumber
asideDrafted from Biran, Cambridge Studies in Islamic Civilization (2005)
The census of the Qara Khitai heartland records something like eighty-four
thousand households. That is a small people holding suzerainty over
Transoxiana, the Semirechye and the Tarim, and everything characteristic about
how they governed follows from it.
They ruled indirectly and almost entirely through people who were already
there. The Karakhanids kept their thrones at Samarkand and Kashgar, the
Khwarazmshahs kept Khwarazm, the Buddhist Uyghur kingdom of Qocho kept the
Tarim, and each remitted tribute and received a Qara Khitai resident to make
sure of it. There was no attempt to settle Khitans on the land, no
redistribution of estates, and — this is the part the Muslim sources
consistently notice — no interference in religion.
The rulers were Buddhist. Their subjects were overwhelmingly Muslim, with
Nestorian Christian, Buddhist and Jewish communities among them. Mosques
functioned, qadis sat, the law was applied, and the Friday sermon was preached
for local rulers rather than for the gurkhan. Muslim writers who had every
reason to describe infidel rule as a calamity mostly describe it as
unobjectionable, and several are notably warmer than that.
Set that against the century it happened in. The Almohads were building a
caliphate on an infallible mahdi. The Fatimids had run a state whose foreign
policy was a missionary organisation. The Abbasids had held the mihna, an
examination of judges on a point of doctrine. The Qara Khitai had no religious
programme at all — not tolerance as a principle argued for, but the practical
indifference of a ruling group too small to impose anything and too sensible to
try.
One further oddity belongs in the same chapter. They kept Chinese imperial forms
nobody around them could read — reign titles, coin legends, a chancery working
in a language with no speakers for two thousand miles. That is a claim addressed
backwards, to a dynasty that no longer existed, rather than outwards to anyone
who was actually present to be impressed.

The refugee who wrecked it
endDrafted from Biran, Cambridge Studies in Islamic Civilization (2005)
Kuchlug was a prince of the Naiman, a confederation on the western Mongolian
steppe that Chinggis Khan broke in 1204. He fled west, was received at the Qara
Khitai court, married the gurkhan's daughter, and in 1211 took the throne from
his father-in-law.
Then he did the one thing his predecessors had never done. Kuchlug — raised
Nestorian Christian, converted to Buddhism, and on any account a man in a hurry
— began persecuting his Muslim subjects: closing mosques and madrasas in the
Tarim oases, requiring conversion to Buddhism or Christianity, and reportedly
having the imam of Khotan crucified on the door of his own school. Eighty years
of a religious policy that had made an infidel suzerainty tolerable were
reversed in about seven.
The Mongols arrived in 1218 under Jebe with instructions that are the point of
the whole episode: proclaim the restoration of religious freedom. The oasis
populations of the Tarim, faced with a choice between a Buddhist persecutor and
a pagan army, treated the Mongol advance as a deliverance and largely did not
resist it. Kuchlug was hunted into the Pamirs and killed. The empire ended
without a battle worth the name.
Two things follow. The Mongols acquired Transoxiana's approaches cheaply and
with a reputation for religious tolerance they traded on across the whole
conquest — a reputation earned, in this particular case, by being less bad than
a usurper. And Khwarazm, which had spent the previous decade throwing off Qara
Khitai suzerainty, discovered in the same year that the buffer between it and
the steppe was gone.
Calling it a conquest is accurate and thin. An empire that had governed by not
asking anything of its subjects was destroyed by a ruler who asked, and then
finished off by an army its subjects preferred to him.
The name that stuck
afterlifeDrafted from Bretschneider, Mediaeval Researches from Eastern Asiatic Sources, volume I (1888)
The empire lasted about eighty-five years and left three things: a reputation
the Mongols spent, a name for China in half the languages of Eurasia, and a
figure Europe waited four hundred years for.
Cathay
The Khitan ruled the northern Chinese frontier for two centuries, and everyone
who reached China across the steppe reached it through them, so Khitan became
the word for the country beyond.
It went west with the Qara Khitai and stayed. Russian still calls China Kitai.
Mongolian, Turkic and Persian all carry versions of it. It reached Latin
Christendom through the Mongol-era travellers as Cathay, and it was still
being used as though it named a country distinct from China three hundred years
later — which is why Portuguese and Jesuit expeditions went looking for Cathay
after Europeans were already living in Canton.
A dynasty that had ceased to exist in China in 1125 gave the country its name in
the language of everyone who approached it from the west, and the name outlived
every state that ever used it.
Prester John
The other export was a rumour.
Word travelled west after Qatwan that a great king from the far east, not a
Muslim, had destroyed a Muslim empire in an enormous battle beyond Persia.
Within a few years chroniclers in the Latin kingdoms were reporting a Christian
priest-king in the east who would come to the aid of the Crusader states, and
the letters, maps and expectations attached to that figure ran for four hundred
years — attaching themselves in turn to the Mongols, and eventually to
Ethiopia.

Bretschneider, Mediaeval Researches from Eastern Asiatic Sources, volume I (1888) · Abraham Ortelius · Public domain
The scholarship generally traces the story to news of 1141. Europe spent four
centuries waiting for rescue from a Buddhist Khitan who had never heard of it.
The reputation the Mongols inherited
The most consequential legacy is the one that is hardest to see, because it
looks like a Mongol achievement.
For eighty years the Qara Khitai had governed Transoxiana and the Tarim by
leaving everything alone: local dynasties on their thrones, a resident to
collect the tribute, mosques open, qadis sitting, no settlement of Khitans on
the land and no interference in religion. Muslim writers who had every reason to
call infidel rule a calamity mostly describe it as unobjectionable.
Then Kuchlug reversed it in seven years, and when Jebe's army arrived in 1218
proclaiming the restoration of religious freedom, the oasis populations treated
a pagan Mongol advance as a deliverance.
The Mongols got Transoxiana's approaches without a battle, and they got
something more useful: a demonstration, in front of the whole Muslim east, that
they were the ones who let people pray. They traded on that reputation across
the entire conquest. It was earned, in this case, by being less bad than a
usurper who had wrecked an arrangement somebody else had built.
The women
One thing the Muslim chroniclers record with notably little comment, and it is
worth setting down.
The throne passed twice to women ruling in their own right: Yelü Dashi's widow
as regent for their son, and later his daughter Pusuwan as gurkhan. Both issued
orders, both were obeyed, and the Persian and Arabic historians who describe
them do so in the ordinary register they use for any sovereign.
For a Buddhist steppe dynasty exercising suzerainty over the Muslim heartland of
Central Asia, that is the most quietly remarkable fact about it, and nobody at
the time appears to have thought it worth an argument.
Yelu Dashi, of the Liao imperial clan, kept the dynastic name, the reign names, the Chinese titles and the Chinese-form coinage after the Jin destroyed the state, and reconstituted them in the Semirechye.
Jebe's army arrived proclaiming the restoration of religious freedom against the usurper Kuchlug, and the Tarim oases treated it as a deliverance rather than an invasion.
