E Daeng Phloeng

E Daeng Phloeng (Thai: อีแดงเพลิง) was a 12th-century monarch mentioned in the Wat Si Chum Inscription as a ruler of the Sukhothai Kingdom.^{[1][2]: 115 [3]: 17} His political authority appears to have been confined predominantly to the territorial bounds of the ancient Sukhothai region, extending westward toward Mueang Rahaeng (เมืองระแหง), which corresponds to the present-day Mueang Tak district.^[4] The precise identification of E Daeng Phloeng, including his historical role and leadership position, remains a subject of scholarly debate,^[1] with phonetic analyses indicating a possible Mon origin.^[5]
