Hanthawaddy Mibaya was the chief queen consort of King Nanda of Toungoo Dynasty of Burma from 1581 to 1599.
Background
Her mother may have been Dhamma Dewi. They were at least half-cousins since her father Tabinshwehti and Nanda"s mother Atula Thiri were half-siblings, and may have been double cousins if her mother was Dhamma Dewi since Nanda"s father Bayinnaung and Dhamma Dewi were siblings.
Career
She was the mother of two heirs apparent: Mingyi Swa and Minye Kyawswa II of Ava. The queen was one of King Tabinshwehti"s two children listed in the Burmese chronicles. She became the chief queen in 1581 when Nanda ascended to the throne.
Nanda presided over the collapse of the Toungoo Empire over the next 18 years.
Minye Thihathu was dismayed, and protected the queen. The queen spent her last years there, and died in June 1606.
