Pua

Pua was a Tai polity in the upper Nan River valley, in present-day northern Thailand. Its exiled ruler Phanong returned and was crowned in 1313, restoring independence from Phayao.

In 1338 Phanong joined Khamfu of Chiang Saen in sacking Phayao, and Pua absorbed its eastern towns. The capital moved south to Nan in 1368. Tilokkaraj of Lan Na bombarded and conquered Pua in 1449; it became a vassal before annexation in 1461. Its Bo Mang salt wells made it a prized possession.
