Suvarnapura Kingdom

Suvarnapura Kingdom or Chên Li Fu (Chinese: 真里富), was a short-lived political entity located on the north shore of the Gulf of Siam, west of Chenla. It was centered in the Phraek Si Racha–Suphan Buri historical regions in present-day Central Thailand, with its sphere of influence extending across the western Chao Phraya Basin, reaching as far south as the modern provinces of Phetchaburi  and Prachuap Khiri Khan,  bordering Po-Ssu-lan to the southeast and Tambralinga to the south. Chên Li Fu sent tribute to the Chinese court in 1200, 1202, and 1205.

Before the rise of Angkor, Chên Li Fu was believed to have been one of the principal polities within the Dvaravati cultural sphere, alongside the Lavo Kingdom in the eastern basin.  O. W. Wolters, whose interpretation was strongly influenced by George Cœdès’ framework of Southeast Asian history, proposed that Chên Li Fu likely became a vassal state of, or came under the influence of, Angkor around the 12th century. However, Songsiri contends that during this period Chên Li Fu may have autonomous status but has close dynastic connections with the Mahidharapura Kingdoms in the Phimai region—contrasting with its eastern neighbor, Lavo, which was fully incorporated into the Angkorian domain.  Some scholars generally identify Chên Li Fu with the Siamese polity of Suphannabhum; however, this contrasts with the account preserved in the Northern Chronicle, which records that Suphannabhum was ruled by another line of monarchs during this period.

In 1205, the Phraek Si Racha region of Chen Li Fu, previously under the authority of Pra Poa Noome Thele Seri, was incorporated into Ayodhya, which at that time was ruled by his son, Uthong II. Notably, this same year coincides with the enthronement of Mahīđharavarman III, identified in Chinese sources as Se-li-Mo-hsi-t’o-pa-lo-hung, who subsequently dispatched a tributary mission to the Chinese court. This chronological convergence strongly suggests a high probability that Mahīđharavarman III may be identified with Uthong II.
