Haripuñjaya

Haripuñjaya was the Mon kingdom of northern Thailand, ruling from Lamphun, itself also called Haripuñjaya, from 661 to its fall to Lan Na in 1292. Chronicle tradition brings its foundress Camadevi, a princess invited from Lavo, Queen Camadevi bearing twins who split Lamphun and Lampang and beating the Lawa king Wilangka at her accession, though modern dating runs anywhere from the seventh to the twelfth century, and the basin's graves and ironworks predate every chronicle. Its art and inscriptions belong to the Dvaravati world of Mon city-states, its seven large Lamphun steles recording gifts, buildings, an earthquake and the 1219 Vat Don inscription. In the twelfth century Adityaraja quarreled with Lavo's kings, her line having warred with Tambralinga's Lavo and the Khmers from 1002, annexing Lavo in 1052, and in 1292 Mangrai's Tai host besieged and took the city, closing six centuries of Mon rule in the north.
