Uthong II

Uthong II (Thai: อู่ทองที่ 2), 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 (จันทรเทวีศรีบาทราชบุตรีศรีทองสมุทร). 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 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 (later enthroned as the Angkoian monarch Indravarman II), 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 ( chữ Hán: 雲屯) to request official authorization for trade and the procurement of goods.
