King Trisong Detsen (Tib. ཁྲི་སྲོང་ལྡེ་བཙན་, Wyl. khri srong lde btsan) or Trisong Deutsen [Déu tsen] (ཁྲི་སྲོང་ལྡེའུ་བཙན་, khri srong lde'u btsan) (742-c.800/755-797 according to the Chinese sources) – the thirty-eighth king of Tibet, second of the three great religious kings and one of the main disciples of Guru Rinpoche.

The Sons of Trisong Detsen
There is some confusion in the various histories regarding the number and the names of Trisong Detsen's sons.
According to Erik Haarh, he had four sons:
Mutri Tsenpo (མུ་ཁྲི་བཙན་པོ་, mu khri btsan po),
Mune Tsenpo (མུ་ནེ་བཙན་པོ་, mu ne btsan po),
Muruk Tsenpo (མུ་རུག་བཙན་པོ, mu rug btsan po) and
Mutik Tsenpo (མུ་ཏིག་བཙན་པོ, mu tig btsan po) who became known as Tridé Songtsen (ཁྲི་ལྡེ་སྲོང་བཙན་, khri lde srong btsan) or Senalek (སད་ན་ལེགས, sad na legs.
The situation is made more complex because later Tibetan sources use several of these names interchangeably. 
In Ancient Tibet , it says that there were three sons:
Desong (ལྡེ་སྲོང་, lde srong) aka Senalek, and
the third son, who is called both Murug and Mutik.
According to Dudjom Rinpoche's History of the Dharma (བདུད་འཇོམས་ཆོས་འཇུང་, Wyl. bdud 'joms chos 'jung, King Trisong Detsen had three sons:
the eldest was named Mune Tsepo,
the middle one Murup Tsepo, and
the youngest Mutik Tsepo, or Senalek Jingyön.
