This is the worldly half of the chronicle genre — dynastic and political history, the record of muang and their rulers rather than relics and Buddhas. It is the smallest of the three chronicle sub-genres at 159 witnesses (against 569 Buddhist Chronicle and 328 Tamnan), but it is the piece that functions as secular memory: how the northern polities remembered their own statecraft.
The titles are the vocabulary of dynastic history. The pongsawadan (Pongsawadan lan na — the annals of Lanna) and the rājavaṃsa lineages (Tamnan lacawong tao phanya mueang lan na, the succession of the lords of Lanna) give the ruling houses their genealogies; the puen mueang city-chronicles (Puen wongsa cao nai … mueang pua lae mueang nan) narrate individual polities; and the biographical phawat cao (Phawat cao mantale) records particular rulers. Named muang recur — Tamnan chiang mai, Tamnan mueang nan — each polity keeping its own version of the story.
Palm-leaf-dominant (134) but with a visibly higher share of undated and paper witnesses than the canon, and dated across an exceptional span — 1742 to 2024, the most recent witness in the entire collection, a sign that secular chronicling continued into living memory and beyond. Its geography breaks the Wat Sung Men pattern cleanly: Phayao leads through Wat Si Khom Kham (26), ahead of Phrae and Chiang Mai, and the material is spread across many temples. Secular history was kept where the polity was, not gathered into one scholastic library — a genuinely regional distribution.
