Old royal clan · Mongolia and the Steppe · as at first light, 1 January 1200

The Tayichi'ut of Tarqutai

The Tayichi'ut are a lineage of the old Mongol royal house.

Ambaghai Khan, who led the Khamag Mongols in the middle of the century and was handed by the Tatars to the Jin and put to death, was a Tayichi'ut. They kept serf families of lesser clans (the Suldus of Sorqan-shira are the best known). When Yesugei died about 1170 Tarqutai Kiriltuq and Todo'en Girte led the Tayichi'ut away from his widow and sons and left them on the Onon; Tarqutai later took the young Temujin and held him in a cangue until Sorqan-shira helped him escape.

On 1 January 1200 the Tayichi'ut hold the middle and lower Onon below Dadal and the Aga steppe, and Tarqutai is the strongest Mongol noyan who is Temujin's enemy. The war of 1200 is in the likely course.

medium

Only the Secret History and Rashid al-Din name him; no Chinese source we know.

Overlord

None. Named among Jamuqa's helpers at Dalan Balzhut; no tie to the Jin known.

What the realm holds

  • Winter and summer pastures on the middle and lower Onon
  • Serf and dependent families (Suldus and others)
  • The old royal prestige of Ambaghai Khan's house

How it was acquired

By descent from the house of Ambaghai Khan; leadership of the house after Qutula Khan's death (no khan since).

Allies and rivals

Enemies: Temujin (since c. 1170), Toghrul by extension. Friends: Jamuqa (English Wikipedia, Rise of Genghis Khan: the Taichiud, frightened by Temujin's power, joined Jamukha; by our memory of the Secret History they also stood with him at Dalan Balzhut) and dependants such as Jirqo'adai of the Besut. Their grievance against the Tatars (Ambaghai's betrayal) is old but not a quarrel of 1200.

The realm that morning

Winter camps on the lower Onon, not pinned. They have not yet been attacked; a war on them is likely in spring or summer 1200 (see the likely course). Whether Jamuqa shares their camps that winter is not known.

Military

Clan levies and followers. Their dependants include good archers such as Jirqo'adai of the Besut. No numbers.

Threats

  • Temujin's growing following upstream
  • Toghrul's help to Temujin
  • Defection of their own serf families

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

  1. Spring and summer 1200Temujin and Toghrul attack; the Tayichi'ut are broken on the Onon; Tarqutai flees and is taken (the Secret History has Shirgu'etu ebugen and his sons Alaq and Naya'a seize him; he is killed).Depends on: Toghrul's help; the Tayichi'ut standing on the Onon. Stopped by: Withdrawal beyond the Onon; Jamuqa or the Merkit coming to their aid early.

Later, on the likely course

  1. 1201 (one line)Survivors join Jamuqa's coalition at the Ergune.Depends on: Escape of Tayichi'ut groups after 1200. Stopped by: Their destruction in 1200.

Where the sources disagree

  • Wikipedia names the Besud (Jebe's clan) and the Suldus (Chila'un's clan) as Tayichi'ut sub-clans and says they share the ancestor Bodonchar with the Qiyat-Borjigin; the Kahn/Cleaves excerpt has camp circles of the Besud and Suldus following Temujin at the parting from Jamuqa, so the sub-clans were split between the two houses.
  • The Wikipedia Taichiud article places them in southern Zabaykalsky Krai and Dornod and does not mention the lower Onon; the regional brief and the Secret History's route descriptions put them on the Onon, and we keep that. Their exact camps are not pinned.

Evidence: Narrative sources only; locations inferred from route descriptions.

On the map: A broad range; the western edge against Temujin (near Dadal) is a guess.
