Trisong Detsen
Trisong Detsen retired to live at Zungkar and handed power to his second son, Muné Tsenpo, in 797. From this point there is much confusion in the various historical sources. It seems there was a struggle for the succession after the death of Trisong Detsen. It is not clear when Trisong Detsen died, or for how long Muné Tsenpo reigned. It is said that Muné Tsenpo was poisoned by his mother, who was jealous of his beautiful wife.
