Buyiruq is the Naiman khan of the mountains.
By the Secret History he is the man the Kereyit and the Mongols chase over the Altai: he is driven from Soqoq-usun, flees down the Urunggu (the Ulungur) and is struck at Lake Kishil-bashi (Kizilbash), usually taken for Lake Ulungur or a lake beside it, in the Year of the Dog (1202). He swears to Jamuqa at the Argun and with Qutuqa of the Oirat tries to raise a storm against Temujin at Koyiten in 1201; the wind turns and he withdraws to Uluq-taq south of the Altai. Rashid's story, taken from Wikipedia's article on Toghrul, gives him Toghrul's runaway brother Erke Qara as a guest about 1198 and the first Kereyit-Mongol war on him in 1199.
His captain is Kokse Sabraq, the Naiman who takes Senggum's wife and son and half of Toghrul's people; his scout is Yeditubluq. He is killed while hunting in 1206.

Secret History 142-144, 158-163, 177 (translation with dating footnotes read online); Wikipedia on Buyruq Khan and Toghrul.
Overlord
None shown.
What it holds
- The Guchugud Naiman of the Altai, a following of herding clans (no count)
- The Ulungur river and lake and the country of Lake Kishil-bash south of the Altai as winter ground; the Altai slopes towards Khovd and the Soqoq-usun as summer ground (Secret History 158; the exact places are not pinned)
- The captain Kokse Sabraq (in his service in the Year of the Dog) and the scout Yeditubluq
- A refuge for Toghrul's exiled brother Erke Qara, about 1198 (Rashid via Wikipedia; medium)
How it was acquired
Divided from Tayang after Inanch Bilge's death with a faction of the Naiman (Wikipedia).
Allies and rivals
Enemy of Toghrul (who wants Erke Qara). Ally of Jamuqa and Qutuqa of the Oirat in 1201; no recorded quarrel with Tayang. The Uyghurs of Qocho lie south of him.
How things stand that morning
On the working reading (Rashid, the Chinese annals, the regional brief's '1199?') Temujin and Toghrul came over the Altai in the autumn of 1199, beat him at Lake Kishil-bash, and on the way home his captain Kokse Sabraq cut off Toghrul's son Senggum: Buyiruq is beaten but not broken, Toghrul's camp is shaken, and Erke Qara, the Kereyit exile, is still his guest. On the Secret History's order of events nothing has yet been fought and Buyiruq sits at peace on the Ulungur with a guest he will not give up. The winter camp is on the Ulungur (the lake, the river, the Kran valley); in the summer he is on the Altai's north-east side.
Wealth
Herds; the Altai pastures and the Ulungur lakes; the road south to Beshbaliq and the Uyghur oases.
Military
Naiman horsemen of his branch; captain Kokse Sabraq, who stood at the Bayidaraq confluence in the Year of the Dog; no castles. No numbers.
Threats
- Toghrul's Kereyit and Temujin, coming across the Altai
- Tayang if the brothers fall out
- A hard winter on the Ulungur
What the year holds
What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.
In 1200
- 1202, only if the Secret History's order is right (the autumn of 1199 and already past on the working reading)Toghrul and Temujin attack him at Soqoq-usun and chase him over the Altai and down the Ulungur to Lake Kishil-bash.Depends on: Toghrul pursuing Erke Qara and the Naiman. Stopped by: A truce, or the campaign having been fought already in 1199.
Later, on the likely course
- 1201At the Argun oath and Koyiten (the storm-stone fails); he withdraws south of the Altai.Depends on: Jamuqa's election as gurkhan. Stopped by: The coalition not meeting.
- 1206Killed while hunting by Mongol pursuers; Kuchlug takes over the Naiman remnant.Depends on: Temujin's victory in 1204 and the proclamation of 1206. Stopped by: Buyiruq's flight beyond reach.
Places of note
- Lake Kishil-bash (the Ulungur lake, by the usual identification): Where the Secret History destroys Buyiruq's force; Kizilbash is generally taken for Lake Ulungur or a lake beside it (not pinned).
Where the sources disagree
- Dating of the war on Buyiruq at Lake Kishil-bash and of Kokse Sabraq's seizure of Senggum's household. Rashid al-Din's order of events, the Chinese annals and the older English histories (Cambridge History of China, vol. 6, pp. 338-339, via Wikipedia's article 'Naimans') put a first campaign by Temujin and Toghrul against Buyiruq in 1199, before the Tayichi'ut war of 1200. The regional brief marks it '1199?', and the central-steppe records (Kereyit and the Khangai belt) treat it as done, so this record uses it as the working reading: by 1 January 1200 the Kereyit and Mongols have beaten Buyiruq at Kishil-bash and his captain Kokse Sabraq has struck back at Senggum on the way home (autumn 1199). The Secret History, in the translation read for this record, tells the same two episodes after the oath at the Argun (Year of the Cock, 1201) and Koyiten, in the Year of the Dog, which its footnotes give as 1202; on that order nothing has been fought between the Naiman and the Kereyit-Mongol allies on 1 January 1200 and both episodes lie in the future. The two cannot be reconciled with certainty and each record carries both. We could not open the Yuanshi or the Shengwu qinzheng lu (ctext and zh.wikisource were unreachable), so the Chinese side rests on secondary citations.
- Wikipedia's Buyruq article says the 1202 attack was by Toghrul's Keraites at 'Soqoq-Usun, near modern Ulaangom'; the Secret History says Chinggis Qahan and the Ong Qan together. The Ulaangom identification is Wikipedia's, not the source's.
Evidence: Buyiruq appears in a few lines of the Secret History, in Rashid's account and in Chinese annals we could not open; his camps and family are not given.
On the map: The Ulungur is the best-supported anchor (Secret History 144, 158); the rest of his range is inferred.
