Trisong Detsen
Trisong Detsen is said to have had four sons. The eldest, Mutri Tsenpo, apparently died young. When Trisong Detsen retired he handed power to the eldest surviving son, Muné Tsenpo ("Mu-ne btsan-po"). Most sources say that Muné's reign lasted only about a year and a half. After a short reign, Muné Tsenpo was supposedly poisoned on the orders of his mother.
