Kingdom of Champasak
In 1695, Sourigna died and was heirless. He had 2 sons, the eldest one having been executed for adultery and the other son having fled to Ayutthaya with his mother, step-mother and 600 followers in February 1686, after his father ordered their execution because he was found to be co-habiting with his half-sister with their full knowledge. This was a chaotic time in Laotian history wherein the empire completely collapsed with the kingdom splitting into 3 new kingdoms: Vientiane, Luang Phrabang and Kingdom of Champasak.
