Mingyi Swe was viceroy of Toungoo from 1540 to 1549 during the reign of his son-in-law King Tabinshwehti of Toungoo Dynasty. He was also the father of King Bayinnaung, as well as key viceroys in Bayinnaung's administration. He rose to the position of viceroy of the ancestral home of the dynasty, after having started out as a royal household servant of Tabinshwehti. All the Toungoo kings from Bayinnaung to Mahadhammaraza Dipadi descended from him.
Background
The genealogy of Mingyi Swe and his first wife Shin Myo Myat, the parents of King Bayinnaung, is unclear. Though there are no extant contemporary records regarding Bayinnaung's ancestry or childhood, different traditions about the king's genealogy have persisted. According to Maha Yazawin, the official chronicle of Toungoo Dynasty compiled two centuries later, Swe was born to a gentry family in Toungoo, then a vassal state of Ava Kingdom. His parents were Taungkha Min and Kayenawaddy, a descendant of viceroys of Toungoo, Tarabya, and Minkhaung I. When he reached adulthood, Swe was married to Myo Myat, a 5th generation descendant of King Thihathu of Pinya and his chief queen Mi Saw U of Pagan Dynasty. Despite the official version of royal descent, oral traditions speak of a decidedly less grandiose genealogy: That the couple were commoners from Ngathayauk in Pagan district or Htihlaing village in Toungoo district, and that Swe was a toddy palm tree climber, then one of the lowest professions in Burmese society. The commoner origin story first gained prominence in the early 20th century during the British colonial period as nationalist writers promoted it as proof that even a son of a toddy tree climber could rise to become the great emperor like Bayinnaung in Burmese society. To be sure, the chronicle and oral traditions need not be mutually exclusive since being a toddy tree climber does not preclude his having royal ancestors.
Whatever their origin and station in life may have been, the couple's lives were changed for good in 1516 when both were chosen to be part of the seven-person staff to take care of the royal baby Tabinshwehti. His wife, who had delivered her second child named Ye Htut just three months earlier, was chosen to be the wet nurse of the prince and heir apparent. The family moved into the Toungoo Palace precincts where the couple had three more sons, the last of whom died young. Myo Myat died in the 1520s, and Swe remarried to her younger sister, who bore him two more sons who later became known as Minkhaung II and Thado Minsaw. His youngest son was born in May 1531. They raised Tabinshwehti like a son of their own, and the prince in turn treated them like his own parents. The prince is said to have deeply respected Swe.
Toungoo royalty
His close ties to the crown prince eventually brought him into the ranks of Toungoo royalty. When Tabinshwehti came to power in 1530, the 14-year-old king took Swe's eldest daughter Khin Hpone Soe as one of his two queens; awarded his father-in-law a royal title of Minye Theinkhathu ; and made him a key adviser. His royal ties became stronger in 1534 when his eldest son Ye Htut was married to Princess Thakin Gyi, younger half-sister of the king. In the next six years, whenever Tabinshwehti and Ye Htut went on military campaigns against the Hanthawaddy Kingdom, Swe was left to govern the capital, first Toungoo and later Pegu, with a sizable garrison. In 1540, Tabinshwehti appointed Swe viceroy of Toungoo with the style of Minye Thihathu. It was the first viceroyship appointment by the king, who had moved the capital of his kingdom to Pegu a year earlier. Swe continued to be treated with great respect by the king in the following years. He was seated to the right of the king, a position normally reserved for the king's most trusted person, in the latter's 1545 coronation ceremony at Pegu. Swe built the Myazigon Pagoda at Toungoo in the same year. Unlike his sons, he rarely went on military campaigns. Rather, his primary job during the king's annual military campaigns was to guard Toungoo from raids from eastern Shan states. He did join the king and his sons in the 1548–1549 invasion of Siam, commanding a regiment. He died in March 1549, within weeks of his return from the front.
