Kraisornrat

Thai chronicles make Kraisornrat a Tai ruler of the northern city-state of Chaliang in the upper Chao Phraya valley. Lavo's court had moved from Lavapura to Ayodhya in the 1080s, and its former seat stood vacant from 1087 until Kraisornrat took it in 1106.

Chaliang then became a northern stronghold of Lavapura, held by the crown prince. Kraisornrat married Suladevi, a princess of Si Satchanalai, and the chronicles name Sai Nam Phueng among his children.
