Sithu Pauk Hla of Yamethin

Sithu of Yamethin (ရမည်းသင်း စည်သူ, ; c. before 1368 – c. 1413), also known by his birth name Pauk Hla, was governor of Yamethin from 1400 to c. 1413. He was the eldest child of Chief Minister Min Yaza, and also served as a senior commander in the Royal Ava armed forces. He fought in all the major campaigns of the Forty Years' War between 1408 and 1412.

Early life
Probably born before 1368, Pauk Hla was the eldest child of an athi commoner family of Nga Nyo and Me Chit from Wun Zin, a rural village in the Kingdom of Ava. He had at least two siblings: one full younger sister Saw Myat Lay, and a half younger brother, Saw Yin; he may have also had another younger brother.

He grew up in the royal capital of Ava (Inwa) from 1368 onwards. His father had entered the service of King Swa Saw Ke, and the entire family had moved to Ava since 1368. His father went on to become the chief minister of the court with the title of Min Yaza.

Career
Pauk Hla's career rose alongside his father's. His career defining appointment came in 1400 when the new king of Ava, Minkhaung I, appointed him governor of Yamethin, a major irrigated district traditionally held by the most senior royals, and gave him the command of a 50-strong royal war elephant company. The appointments came alongside Minkhaung's other appointments which included Yaza's son-in-law Thado Theinkhathu being made governor of Badon and Tabayin. The appointments were designed to retain Min Yaza's support by the new king, who had come to power only after a contentious succession crisis. Indeed, the Yamethin governorship previously belonged to Maha Pyauk of Yamethin, who had tried to seize the Ava throne from Minkhaung.

Pauk Hla, now known by the title of Sithu, loyally served as governor for the next dozen plus years. As governor of a major fief, Sithu served in the Royal Ava Armed Forces, and fought in various campaigns—from Hanthawaddy in the south (1408–1410), to Arakan in the west (1411–1412) to Hsenwi in the northeast (1412). He led entire armies in the 1408, and 1409–1410 campaigns, and later served as one of the deputy commanders in Crown Prince Minye Kyawswa's armies from 1410 onwards.

He is not mentioned in the royal chronicles again after 1412. The Yazawin Thit chronicle cursorily mentions that King Minkhaung appointed Sithu Thihapate governor of Yamethin in late 1413 but does not say what had ever happened to the previous governor. While it is not clear if Sithu Pauk Hla had fallen in action or had died by natural causes, he did not lose the governorship because his father had lost power. Min Yaza remained the chief minister of the Ava court until his death in 1421.
