Rajadhiraj II
king of Si Satchanalai
Rajadhiraj II (Thai: ราชาธิราชที่ 2) 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 Sri Naw Nam Thom—who had established dynastic ties with Angkor through the marriage of his son, Pha Mueang, to Sukhara Mahadevi, 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.
Begin with the source’s own compact description: “Rajadhiraj II” is king of Si Satchanalai. The dossier treats that line as a proposition to test through Rajadhiraj, king and Satchanalai, not as a finished interpretation.
Why this record matters
The phrase “king of Si Satchanalai” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Aug 21, 2026. The linked authority identifier is Q136679045. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1219.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
