The Khon are an old noble family of Tsang, and their house is the only one of the Tibetan monastic powers where the headship is inherited inside a family: Khon Konchok Gyalpo (1034-1102) founded Sakya in 1073, his son Sachen Kunga Nyingpo (1092-1158) made it famous, and three of Sachen's sons followed him as the 'white-robed' lay patriarchs: Sonam Tsemo (1142-1182), Drakpa Gyaltsen (1147-1216) and the fourth son, Palchen Opoche (1150-1203), who is the family's father and not its head.
On 1 January 1200 three generations are alive: Drakpa Gyaltsen (52) as head and teacher; Palchen Opoche (about 49) with his wife and sons; and Sakya Pandita (17) and his brother Zangtsa Sonam Gyaltsen (about 15, recalled). Zangtsa's sons Phagpa (born 1235) and Chana Dorje (born 1239) are the generation that the Mongols will use, and they do not exist yet. Which stewards (gnyer), patrons (bdag po) and lay lords serve the household the pages do not say.
The land of the house is the Sakya valley and the estates the founders won by gift; the rest of Tsang is held by other families whom no source we opened names.

Wikipedia (Sakya, Sakya Pandita) and the brief: the Khon head passes from brother to brother and uncle to nephew. Sonam Tsemo (1142-1182) died in 1182, Drakpa Gyaltsen (1147-1216) is the head until 1216, when Sakya Pandita succeeds.
Overlord
none: no one rules Tibet in 1200; the house answers to its own patrons and to the custom of the valleys
What it holds
- Sakya valley and the North Monastery (see the religious record Sakya for the drawing)
- The household of the head (bla brang): kin, servants and the stewards whom no source names
- Estates and tenants, gifts of disciples (not itemised)
How it was acquired
1073: Khon Konchok Gyalpo's foundation. Headship by family succession since.
Allies and rivals
No ally or rival of the house is named for 1200. Its teachers and pupils reach into Kadam and Kagyu houses (Sonam Tsemo is listed among the Sangphu masters on the Kadam page).
How things stand that morning
A famous teaching house in Tsang with three generations in view and no political reach.
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.
Threats
- The succession depends on Palchen Opoche's sons: Drakpa Gyaltsen has no recorded son.
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.
- 1203Palchen Opoche dies.Depends on: Natural death on its date (Wikipedia, Sakya Pandita). Stopped by: A change in his circumstances in play.
- 1216Drakpa Gyaltsen dies; Sakya Pandita becomes head.Depends on: Natural death on its date. Stopped by: A different choice of the family.
- 1235-1239Phagpa (1235) and Chana Dorje (1239) are born to Zangtsa Sonam Gyaltsen (recalled).Depends on: Natural births. Stopped by: A change in Zangtsa's circumstances.
Where the sources disagree
- The brief says 'Sakya Pandita, about 17, is studying': agrees with the pages. Zangtsa's age is from our recollection.
- Chinese Wikipedia (Sakya monastery) says Drakpa Gyaltsen led the monastery 57 years; with the dates above it is 34 (1182-1216). Not used.
Evidence: The family tree to the second generation after Sachen is on the Wikipedia pages in two languages; the household and its servants are not. 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. Dates: 1200 is an Iron-Monkey year in the Tibetan cycle (the first sixty-year cycle began in 1027, a Fire-Hare year); 1 January 1200 falls in the closing weeks of the Earth-Sheep year (1199), before the Tibetan new year. Western years below are the ones the cited pages give; the Tibetan histories give animal-years and the conversions differ by a year or two.
On the map: No map part: the land is drawn on Sakya.
