Dhammikaraja

Dhammikaraja was the fourth sovereign of Xiān at Ayodhya. The extant historical sources provide limited detail regarding his reign. Nevertheless, it is generally characterized as a period of economic prosperity and the flourishing of Theravāda Buddhism, as evidenced by the construction of several religious monasteries attributed to his patronage. According to the Ayutthaya Testimonies, he ascended the throne at the age of fifteen, which suggests a birth year of approximately 1150. By 1157, they had shifted southward and assumed control over Singburi. and Phrip Phri in 1188. Some scholars further suggest that Uthong II may have entered into a matrimonial alliance with Dhammikaraja’s daughter.

An alternative tradition recorded by Jeremias van Vliet describes him as a Chinese prince who had been exiled from China. However, this account appears to conflict with other traditions: both the Northern Chronicle and the Ayutthaya Testimonies state that the father-in-law of Uthong II—whom some scholars have identified with Dhammikaraja—was a descendant of Sindhob Amarin (r. 937–996).
