Tsona is the highest town on the Tibetan side of the Mon country (Monyul), the traditional name for the valleys south of the Himalaya from Tawang to Bhutan.
The Tsona dzong and the Mon-Tibetan trade in rice and salt belong to later centuries; in 1200 it is a border settlement where Tibetans, Mon (Monpa) and Lhoba meet. The Monyul page says nothing of Tsona; the position is from our notes (27.99 N, 91.95 E, the modern county seat of Cona).
Who holds it
- Title
- Headman of Tsona
- 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
Border 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
Where the sources disagree
Evidence: The Monyul page and recollection. 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.
