Photisarath

Photisarath (also spelled Phodhisaraja, Phothisarat, or Potisarat, , 1501–1548), son of King Visoun of Lanxang, is considered to be the most devout of the Lao kings. He banned spirit worship and built temples upon the sites of spirit shrines. His elephant fell and crushed him while he sought to display his prowess to the diplomatic corps. His son Setthathirath returned from Chiang Mai to succeed him to the throne of Lan Xang.

Phothisarath was ruler (1520–47) of the Lao kingdom of Lan Xang whose territorial expansion embroiled Laos in the warfare that swept mainland Southeast Asia in the latter half of the 16th century. King Chairachathirat of the Ayutthaya Kingdom invaded Vientiane with a large army in 1540, captured Muang Khouk and crossed the Mekong, but succumbed to a rout at the battle of Sala Kham, the remnants fleeing for their lives and leaving enormous casualties behind. Phothisarath himself allied himself with Burma, sent out 3 campaigns against the Ayutthaya Kingdom: the first to Phitsanulok in 1535, the second one to Vieng Prangarm in 1539, and third was sent in 1548 to Vieng Prab (now Sawangaburi) where he brought back 20,000 families to settle in the Lan Xang kingdom.
