Thihathu of Prome

Thihathu (d. 1288) was a son of King Narathihapate, the last sovereign ruler of the Pagan Empire, and served as viceroy of Prome from 1275. During the Mongol invasion his father fled Pagan and submitted to the Mongols in 1287; when the king passed through Prome, Thihathu seized him in 1287 and forced him to swallow poison.

He then murdered a rival half-brother and marched on Dala and Pegu, where in 1288 he accidentally killed himself with his own crossbow bolt.
