Thawun Nge was governor of Toungoo from 1317 to 1324. He came to office by assassinating his elder brotherThawun 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 . 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. The fight between the rival governors took place during a brief interregnum following the death of King Uzana of Pagan May 1256. At the capital Pagan, a power struggle broke out between Crown PrinceThihathu 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, he may have backed Thihathu. Thawun Nge had an elder brother named Thawun Gyi, who like him was also born in Pyu. The brothers grew up listening to their father's constant reminders about their royal descent from King Sithu II of Pagan—the two brothers were two-times-great-grandsons of Sithu II—and their rightful claim to the Kanba Myint region, which was given in fief to their ancestor Ananda Thuriya by Sithu II. Their father died in early 1279. Per Toungoo Yazawin, his last words to his two sons were to reclaim their rightful land.
Deputy ruler of Toungoo
After their father's death, the two sons along with the followers 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 because of its location by the hills in the narrow Sittaung river valley between the Bago Yomarange 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, who ruled only around Pagan, but submitted to the Myinsaing rulers later at an unspecified date. 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, his men assassinated Thawun Gyi in the precincts of the Tayahte 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 the chief wife and Princess Saw Omma. His son Saw Hnit succeeded.
