Rajadhiraj II

Rajadhiraj II is recorded in the Northern Chronicle as a monarch of Mueang Chaliang (Si Satchanalai). He was the youngest son of Dharmatriloka and ascended the throne following his father’s reign in the early 13th century, as his two elder brothers, Dhammaraja and Baramaraja, were unable to return to Chaliang after entering into matrimonial alliances with princesses of Ayodhya.

The source provides no further information regarding the administrative activities or achievements of Rajadhiraj II. His reign, however, appears to have been brief, as the emergence of a new Tai dynasty led by —who had established dynastic ties with Angkor through the marriage of his son, Pha Mueang, to , a princess under Jayavarman VII —brought about a significant shift of political power in Mueang Chaliang. In 1219 CE, after established their power in Mueang Chaliang, this new dynasty successfully captured Sukhothai from E Daeng Phloeng, a Mon monarch potentially identifiable as the successor of Candraraja of the Xiān lineage from the Padumasuriyavamsa dynasty.
