Thawun Nge

Thawun Nge (, ; 1260 – 1324) was governor of Toungoo (Taungoo) from 1317 to 1324. He came to office by assassinating his elder brother Thawun Gyi while Toungoo's overlord Pinya was facing a serious rebellion at Sagaing. His own rebellion was brief as he struck a deal with Pinya to keep the office in exchange for his submission. He died in 1324, and was succeeded by his son Saw Hnit.

Early life Thawun Nge was the younger son of Thawun Letya, the ex-governor of Kanba Myint and Kya-Khat-Wa-Ya (both in modern Taungoo District). He was born after 1256. According to the regional chronicle Toungoo Yazawin, he was born in Pyu where his father had been placed under house arrest since 1256 by a rival governor from a Mon state to the south, which most likely was Pegu (Bago). The fight between the rival governors took place during a brief interregnum following the death of King Uzana of Pagan (Bagan) May 1256. At the capital Pagan (Bagan), a power struggle broke out between Crown Prince Thihathu and his half-brother Narathihapate. The court-backed Narathihapate emerged winner by November 1256. Since Thawun Letya remained under house arrest until his death in 1279,

Deputy ruler of Toungoo After their father's death, the two sons along with the followers (370 households) left Pyu for the north. They decided to settle at a location, about 55 km from Pyu and about 40 km south of Kanba Myint. It was named Toungoo (Taungoo) (, "Hill's Spur") because of its location by the hills in the narrow Sittaung river valley between the Bago Yoma range and southern Shan Hills. The date of foundation was 17 April 1279.

According to Toungoo Yazawin, Thawun Nge was the more ambitious of the two brothers. He wanted the top job but had to relent as Thawun Gyi became the ruler by primogeniture. Thawun Nge settled for being the deputy. Toungoo became independent in 1287 when its overlord Pagan fell due to the Mongol invasions. Thawun Gyi never submitted to King Kyawswa (r. 1289–97), who ruled only around Pagan,

By the 1310s, Thawun Nge was getting impatient; he had been waiting in the wing for over three decades. His opening came in 1315 when Toungoo's overlord Myinsaing–Pinya faced a rebellion at Sagaing. What began as a minor thinly veiled insurrection by Prince Saw Yun against his father King Thihathu grew serious by March 1316 when Saw Yun completely fortified Sagaing. Thihathu sent two expeditions to retake Sagaing but both failed. Thawun Nge decided that it was time to remove his brother. On or right before the beginning of the Buddhist Lent that year (23 June 1317), his men assassinated Thawun Gyi in the precincts of the Tayahte Pagoda (modern Myat Saw Nyi-Naung Pagoda).

Ruler of Toungoo Thawun Nge was now finally the ruler. But by having assassinated Thawun Gyi without Pinya's permission, he was also in revolt. He was not alone, however. Toungoo's neighboring state, Taungdwin had also revolted. Thihathu did send an army led by Crown Prince Uzana, which laid siege to Toungoo. Thawun Nge successfully negotiated a deal to keep his office in exchange for his submission to Pinya. He ruled for seven more years before his death in 1324. He had two wives, Princess Saw Sala who was the chief wife and Princess Saw Omma. His son Saw Hnit succeeded him.
