Tamna chiefs

Tamna was a separate kingdom that English Wikipedia says was subjugated in 938 and officially annexed in 1105 (when we recall Goryeo made it a county (gun)); a county official was sent in 1153 [not yet checked against the source].

The old chiefs kept the titles Seongju (the Go clan, West Tamna) and Wangja (the Moon clan, East Tamna) (English Wikipedia says local autonomy lasted to 1404) and the tribute of horses, abalone, tangerines and seaweed goes north under them. The island rose in 1168 under Yang Su against a tax-greedy magistrate [not yet checked against the source] and rises again in 1202 (the Chinese Wikipedia list of Choe-era risings has a Tamna revolt that year). The Mongol horse farms are of 1273 and not yet.

We give no chief's name.
