Mangyül Gungthang
Mangyül Gungthang was a Tibetan kingdom in the Kyirong valley near Nepal, ruling from Dzongka on a trans-Himalayan trade route. Founded around 1265 by Bumdegon, it was one of the thirteen myriarchies of Yuan-era Tibet.
In the fifteenth century the princess Chökyi Drönma, daughter of King Tri Lhawang Gyaltsen, became the first Samding Dorje Phagmo, Tibet's highest female reincarnation. Gungthang repelled a Rinpungpa invasion in 1555, but after successive Central Tibetan overlords it was destroyed by the King of Tsang in 1620.
