Hnin U Yaing


Hnin U Yaing was a princess of Martaban and the mother of two kings, Saw O and Saw Zein.
She helped her eldest brother Wareru seize the governorship of Martaban in 1285. In 1311, she and her husband, Governor Min Bala of Myaungmya, overthrew her brother, King Hkun Law, and placed their eldest son, Saw O, on the throne.

Brief

U Yaing was born to commoner parents in Donwun, then part of the Pagan Kingdom. She had at least two elder brothers, Ma Gadu and Ma Gada. The siblings were of Shan and/or Mon background.
According to the Razadarit Ayedawbon, U Yaing played an import role in the rise of her eldest brother's early rise to power. Gadu reportedly used his younger sister's good looks to seize the governorship of Martaban, the provincial capital. Gadu asked U Yaing to choose her bathing place in a river spot strategically, where Governor Aleimma of Martaban would see her. The governor fell in love with U Yaing, and asked to marry her. At the wedding ceremony, Gadu killed the governor, and became the rebel lord of Martaban. Gadu, now styled as King Wareru, went on to declare independence from Pagan in 1287, and to consolidate all three Mon-speaking provinces of Lower Burma by the mid-1290s.
U Yaing rose along with her brother. Wareru appointed U Yaing's husband Min Bala governor of Myaungmya, in the westernmost province. By 1307, when Wareru was assassinated by his grandsons, U Yaing and Bala were entrenched in the delta. They did not respect her other brother, Gada, who succeeded as King Hkun Law. In March 1311, the couple went to the capital and seized the throne while Law was on a hunting trip. Bala's troops subsequently killed Law at the outskirts.
Although Bala initially wanted to ascend the throne, U Yaing objected. Her rationale was that Bala was too old already, and that their eldest son, Saw O, as a nephew of Wareru, would stand a better chance at gaining the support of the vassals. Bala finally yielded to his wife's demand, and Saw O ascended the throne on 10 April 1311.
U Yaing and Bala both died from old age in the mid-to-late 1310s. The couple had at least three sons, two of whom—Saw O and Saw Zein—became kings of Martaban.
