The people of the upper Brahmaputra and the Lohit: later the Chutia kingdom of Sadhayapura (Sadiya), which English Wikipedia says was "believed to be founded in the early 13th century around Sadiya", before the Ahoms arrive in 1228.
It names no founder and says the Chutia ruler lists "cannot be traced to earlier than 19th century"; the earliest securely attested Chutia ruler is Nandin in the late fourteenth century. For 1 January 1200 there is a country of tribal chiefs and a Brahman shrine at Parasuram Kund, but no Chutia king.

Places of note
- Sadiya: Sadhayapura.
- Parasuram Kund: Pilgrim bathing place on the Lohit.
Where the sources disagree
- The campaign board entry sadiya-country is "contested" under Kamarupa; English Wikipedia says the Chutia state emerged after the fall of Kamarupa, in the early thirteenth century. We draw it as peoples' ground.
Evidence: Chronicles of the nineteenth century and a plate of 1392; nothing from 1200.
"The campaign board" is OMNIA's working map. These notes record where its earlier claims were checked against the sources.
On the map: The range is drawn as a province (the matching nie-prov record); this record draws no ground of its own.
