Uthong II
Uthong II, or Mahidharavarman III, the fifth king of Xiān at Ayodhya, who was of mixed Siamese Mon–Chinese–Cham heritage, ascended the throne following his father-in-law Dhammikaraja, who left only a daughter, Phummawadi Thewi, married to Uthong II, prince of Phrip Phri. Uthong II was born to Pra Poa Noome Thele Seri and the Cham-Chinese queen Chandradevi. Upon his death, Jayasena, his son-in-law who was also the younger prince of Phichai Chiang Mai or Phetchaburi, succeeded him.
During his reign, Ayodhya’s authority extended west to Tanintharyi in present-day southern Myanmar. To the north, Phraek Si Racha, the seat of Xiū Luó Fēn and later Chen Li Fu—which was under his father in from 1180 to 1204—was left without a ruler between 1249 and 1299. To the east, adjoined Lavapura in Lavo, which as was administered by Nripendravarman, a prince serving under the Angkorian monarch Jayavarman VII.
Commercial relations with Đại Việt, first established in 1149, were maintained in subsequent centuries. Documentary evidence records that in 1241, a naval merchant mission from Xiān arrived at Yún tún to request official authorization for trade and the procurement of goods.Biography
Genealogy
The Ayutthaya Testimonies identify Uthong II as the son of Queen Consort Mani Mala. In contrast, the ' records that the king of Kampoch —likely Dhammikaraja —died without a male heir, after which the throne was offered to the wealthy noble named Uthong, who relocated the capital southward in response to epidemic outbreaks. The ', which contains a mixed story of Uthong I, Uthong II, and Uthong V, similarly recounts that a son of a wealthy merchant named Uthong became ruler of Ayodhya. This account aligns with the , which states that Pra Poa Noome Thele Seri, king of Phrip Phri who prospered through maritime trade with China, married Chandradevi, a daughter of the Chinese emperor and a Cham princess Chandramouli, and that their son, Uthong, subsequently ascended the throne of Ayodhya. Taken collectively, these sources suggest that Uthong II was the offspring of Pra Poa Noome Thele Seri and Chandradevi, a Cham-Chinese princess.Issues
According to the , Uthong II had four children: three sons and one daughter. The eldest son, Ai, was appointed governor of Mueang Nakhon, a city that some scholars have identified with Nakhon Si Thammarat of Tambralinga in the south. However, at the time in question, Nakhon Si Thammarat was demonstrably ruled by descendants of Sri Dharmasokaraja II, suggesting that the chronicle may instead be referring to the former capital of Indaprasthanagara. The second son, Yi, was sent to rule Tanintharyi in the far west, while the youngest son, Sam, succeeded his uncle Thonglanraj as ruler of Phrip Phri. His only daughter, Rajadevi, reportedly entered into a clandestine relationship with Jayadatta, the eldest son of the king of Phichai Chiang Mai, and bore a son, Suvarnaraja, who later reigned as king of Ayodhya from 1289 to 1301.
