Following of a sworn brother · Mongolia and the Steppe · as at first light, 1 January 1200

Jamuqa's following

Jamuqa is Temujin's sworn brother (anda) from boyhood and his rival since the two parted camps.

He leads the Jadaran, a Mongol clan of Turkic descent, and in the Secret History he is the natural leader of the old aristocracy who object to a khan who raises low-born companions. At the parting it was Jamuqa who proposed to camp apart; Temujin's people marched on through the night on Borte's advice and by dawn camp circles from nearly all the clans had followed Temujin, with Chaghan Uua of the Chinos from Jamuqa's own camp and Daritai with families of the Jadaran, so Jamuqa's own clan is split (Kahn/Cleaves, pp. 44 to 48).

He beat Temujin at Dalan Balzhut and boiled prisoners alive, which turned many clans against him; English Wikipedia (Rise of Genghis Khan) says his disgusted allies went over to Temujin and that, with fewer men, he could no longer challenge Temujin on the upper Kherlen and 'retreated further east'. Since then the sources say almost nothing of him, except that the same page has him in a Merkit raid with Toghrul and Temujin in 1191 and, in 1199, riding with them against Buyiruq of the Naiman beyond the Altai (a campaign the Secret History's order places after Koyiten). On 1 January 1200 he is a chief without a state: his own Jadaran, a handful of followers, and ties to the Tayichi'ut and the eastern clans that are not yet formal.

Where he is that winter is not stated in any source: the middle Kherlen is our placing from the route descriptions, not a fact.

What the realm holds

  • The Jadaran, their herds and winter pasture
  • Whatever followers stayed after the Chinos prisoners were boiled

How it was acquired

By descent in the Jadaran chiefly house.

Allies and rivals

Anda and rival of Temujin, though English Wikipedia has them campaigning together in 1191 and 1199. The Tayichi'ut joined him out of fear of Temujin (same page). No coalition stands behind him on 1 January 1200; the coalition of 1201 is in the likely course.

The realm that morning

Not pinned. No source places Jamuqa on a river that winter. The draw puts him on the middle Kherlen and the lower Ulz, between Temujin and the eastern clans, as the least harmful guess; English Wikipedia says only that after the parting he withdrew east of Temujin's upper Kherlen. If the 1199 Altai campaign is a fact (Wikipedia's dating) he spent that autumn in Toghrul's company and has come back east since.

Military

His own clan levy; no numbers.

Threats

  • Isolation after Dalan Balzhut
  • Temujin's growth
  • Toghrul

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. 1200Jamuqa stays out of the Tayichi'ut war or gives it only indirect help.Depends on: No coalition has formed yet. Stopped by: A Tayichi'ut appeal that he answers early.

Later, on the likely course

  1. Autumn 1201 (one line)Elected gurkhan on the Ergune; the coalition fights at Koyiten.Depends on: The Tayichi'ut and eastern clans seek a leader. Stopped by: Temujin's victory in 1200 breaks them first.

Where the sources disagree

  • The regional brief asks where Jamuqa is and who follows him: the honest answer is that no source says. The Wikipedia Jamukha article gives no camp and no pre-1200 event after Dalan Baljut.
  • English Wikipedia (Rise of Genghis Khan) has Jamukha with Temujin and Toghrul in a Merkit raid in 1191 and against Buyruq west of the Altai in 1199. The Secret History's order puts the Naiman fights after Koyiten, and a Jamuqa who rides with Toghrul in autumn 1199 does not fit the plain 'rival' of the standard account. Treat his standing with Temujin and Toghrul on 1 January 1200 as open.

Evidence: Almost nothing is recorded of Jamuqa between Dalan Balzhut and 1201.

On the map: Low confidence. Treat the whole polygon as 'where Jamuqa's Jadaran probably graze', not as a camp.
