Yadong (Xarsingma)

The lower Chumbi valley (Dromo, 'the valley of the Mo') is a green wedge of the Tibetan plateau that reaches south of the Himalaya between Sikkim and Bhutan.

Its farmers, the Dromowa, grow barley and keep yaks, and control the Nathu La and Jelep La routes to Sikkim (the Chumbi page names those passes only in nineteenth-century material). The Chumbi page says that in 1206 Bakhtiyar Khilji invaded Tibet through the valley and was beaten back; this is the one dated event, and it is after 1 January 1200 (see the province record). The gazetteer's 'Yadong' is a place in Inner Mongolia and is not used; Xarsingma is the modern county seat.

Who holds it

Title
Lord of the Dromo valley
Since
not pinned
Confidence
low

No source we could open names the holder for the winter of 1199-1200.

Overlord

none: no one rules Tibet in 1200; the house answers to its own patrons and to the custom of the valleys

How things stand that morning

Valley settlement; lord not known.

Wealth

No source we could open gives figures; the usual base is estates and serfs, herds, pass tolls, trade in salt, wool, tea and barley, and the gifts of patrons.

Military

No standing army; the house or lord calls on retainers, tenants and kin. No troop numbers are given by any source we could open.

Council

none known; the place is governed by its lord or house, and no source we could open names a headman or judge

Communities

Tibetan; no other community is attested here

Fairs and markets

none known; pilgrims and caravans meet at the feasts of the temples, but no fair is dated

Walls and castle

none known; the dzong (fort) as an institution of the district lord belongs to the fourteenth century

Trade and crafts

not described by any source we could open

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.

  1. 1205-1206Bakhtiyar Khilji's expedition from Bengal reaches Tibet by the Chumbi valley and is repulsed (en Wikipedia, Chumbi Valley, gives 1206).Depends on: Bakhtiyar's conquest of Nadia in Bengal (dated 1203 or 1204 on different accounts) and a march from Bengal into the hills; the Chumbi page gives 1206 and the route is debated. Stopped by: No conquest of Bengal.

Where the sources disagree

  • The gazetteer has a Yadong in Inner Mongolia (48.5 N, 123.8 E): do not use the bare name.

Evidence: Wikipedia (Chumbi Valley). Treasury of Lives, the Blue Annals, the Red Annals, Petech, Sorensen and Hazod and Davidson could not be opened in this session (treasuryoflives.org and rigpawiki.org refused the fetch; the archive.org full texts were refused or cut off), so facts marked 'recalled' are from memory of those works and unchecked.
