Li Thai (Maha Thammaracha I)

Li Thai, known posthumously as Maha Thammaracha I, was king of Sukhothai from about 1347 until his death in 1368. The son of King Loe Thai, he ruled Si Satchanalai as viceroy before taking the throne.

A devout Theravada Buddhist, he built Wat Phra Si Rattana Mahathat at Phitsanulok and wrote the Trai Phum Phra Ruang, on Buddhist cosmology and a righteous king's duties, the first major Buddhist text composed in Thai. He was succeeded by his son Lue Thai.
