Ngua Nam Thum

Ngua Nam Thum was a king of Sukhothai of the House of Phra Ruang. The Jinakalamali chronicle makes him a son of King Ban Mueang, nephew of Ram Khamhaeng and cousin of Loe Thai, whom he followed on the throne around 1323.

Around 1340 he named Loe Thai’s son Li Thai his heir and ruler of Si Satchanalai. In 1347 or 1348, the Wat Pa Mamuang inscriptions record, Li Thai marched on the capital, killed his enemies and took the throne as Mahathammaracha I.

One historian has suggested that Ngua Nam Thum died that same year and that Li Thai seized the throne before the late king’s son could succeed him.
