Trisong Detsen
Trisong Detsen retired to live at the palace 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 Mune Tsenpo reigned. The "Testament of Ba", a Tibetan historical text which may date back to the 9th century, claims that Muné Tsenpo insisted that his father's funeral be performed according to Buddhist rather than traditional rites.
