Trisong Detsen retired to live at Zungkar and handed power to his second son , Mune 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 . It is said that Mune Tsenpo was poisoned by his mother who was jealous of his beautiful wife . Whatever the case , both the Old Book of Tang and the Tibetan sources agree that , since Mune Tsenpo had no heirs , power passed to his younger brother , Sadnalegs , who was on the throne by 804 CE. The other brother , Mutik Tsenpo , was apparently not considered for office as he had previously murdered a senior minister and had been banished to Lhodak Kharchu near the Bhutanese border . As he was quite young when he came to the throne , Sadnalegs was assisted by four experienced ministers , two of whom were also Buddhist monks . They followed the policies of the previous kings . Sadnalegs had four wives from different Tibetan clans . What is the relationship between 'sadnalegs' and 'emperor'?
