Sricandradhipati

Sricandradhipati, also known as Phra Ruang II, is a legendary monarch mentioned in the Legend of Phra Ruang. According to the narrative, he originated from Lavo Kingdom and was said to be the son of a commoner named Kongkrao. He was subsequently offered the throne of Sukhothai in 959 CE.
The legend recounts that while residing in Lavo, Ruang was assigned the duty of collecting tribute for submission to Indapraṣṭhanagara, which has been tentatively identified with Yaśodharapura of Chenla by early Thai scholars. However, when the king of Indapraṣṭhanagara ordered his arrest, Ruang fled—first to Phichit and subsequently to Sukhothai—where he entered the Buddhist monastic order. In 959 CE, following the death of the reigning monarch of Sukhothai, who left no direct heir, the local populace invited Phra Ruang to leave the monkhood and he ascended the throne under the regnal title Sricandradhipati.
There is no extant record identifying his immediate successor. However, Thai historian Birihan Thepthani has postulated that Arunaraja, the son of Sricandradhipati’s predecessor and then-ruler of Mueang Chaliang, assumed sovereignty over Sukhothai, thereby establishing a dual monarchy. Aruṇa Kumāra is further said to have proclaimed independence from Umoṅkaselā in 1017 CE.
