Chiefs of the upper Nan

The upper Nan is settled, rice-growing and works the salt above it, with no attested muang seat on 1 January 1200.

The valley is here and the state is not yet. The Nan Chronicle (compiled in the Bangkok period) puts the ruling line at Pua under Khun Fong in the thirteenth century; Phayao takes Pua in 1263.
