Thihapate of Tagaung (Burmese: သီဟပတေ့, in Burmese pronounced as /θìha̰pətḛ/; also known as Nga Nauk Hsan (ငနောက်ဆံ, in Burmese pronounced as /ŋə naʊ̯ʔ sʰàɴ/); d. November 1400) was governor of Tagaung from 1367 to 1400.[1] The powerful governor of the northernmost vassal state of Ava was a brother-in-law of King Swa Saw Ke,[2] and had even served as a tutor to Crown Prince Tarabya.[3] [4] In 1380/81, he was even considered by King Swa Saw Ke as a candidate to become king of Arakan although he was ultimately passed over.[5]
Thihapate came to Ava (Inwa) in 1400 to serve as an advisor to his one-time pupil Tarabya, who had become king. With Tarabya becoming mentally unstable, Thihapate assassinated the young king in November 1400,[6] and tried to seize the throne. But the Ava court did not accept him, promptly executed him.[5]
