E Daeng Phloeng

E Daeng Phloeng was a 13th-century monarch mentioned in the Wat Si Chum Inscription as a ruler of the Sukhothai Kingdom. His political authority appears to have been confined predominantly to the territorial bounds of the ancient Sukhothai site, extending westward toward Mueang Rahaeng , which corresponds to the present-day Mueang Tak district. The precise identification of E Daeng Phloeng, including his historical role and leadership position, remains a subject of scholarly debate, with phonetic analyses indicating a possible Mon origin.

In 1219, E Daeng Phloeng was overthrown by , a Tai monarch from Mueang Chaliang, who subsequently established dual sovereignty over Mueang Chaliang and Sukhothai. The kingdom under the lead of and Pha Mueang significantly expanded by consolidating several other polities.
