Phra Chao Luang
Phra Chao Luang, the second sovereign of Xiān at Ayodhya, acceded to the throne in 1089 following his successful resolution of a protracted succession dispute among the nine noble clans of Ayodhya that had arisen after the death of King Narai I. The civil conflict is believed to have inflicted severe devastation upon the city, resulting in significant depopulation and long-term instability. It is further suggested that factional tensions within the royal court persisted throughout his reign.
The extant records of Phra Chao Luang’s twenty-two–year reign provide only limited testimony regarding his political and military activities. Nonetheless, they preserve significant evidence of his contributions to economic organization and religious patronage. According to the, he instituted the establishment of Akorn Khanon, a form of tax office, in every subdistrict, thereby systematizing fiscal administration. In 1098, he relinquished the royal palace to facilitate the expansion of the principal Buddhist temple precinct, which subsequently became known as Wat Doem or Wat Ayodhya. A new royal palace was thereafter constructed to the south of the site of the present-day Wat Phanan Choeng.
Phra Chao Luang remained on the throne until 1111. As he died without a male heir, the polity entered a brief interregnum. Historical tradition records that the king was survived by a single daughter, Rajadevi, who was married to Duangkrian Krishnaraja, son of King Kesariraja of Lavo. They then went to ruled Kishkindha in the present-day Saraburi province.
During the ensuing vacancy of the throne, it is posited that political authority in the region temporarily shifted to Lavo. Shortly thereafter, the throne of Ayodhya was offered to a commoner, Sai Nam Peung, who assumed the kingship.
