Sadnalegs

[1][2] Whatever the case, both the Old Book of Tang and the Tibetan sources agree that, since Muné Tsenpo had no heirs, power passed to his younger brother, Sadnalegs, who was on the throne by 804 CE.

[3][4] 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.

In order to test the majesty of the young prince, the ministers let him sit on a seat and put many precious ornaments on his head.

Finally he inherited the throne, and thus got a nickname, Sénalek Jingyön, which meant "The crooked neck [child] who had been examined and [recognized as] the proper [emperor]".

[10][11] The Tibetan army continued to attack the Arabs to the west and, according to al-Ya'qubi, they besieged Samarkand, the capital of Transoxiana at the time.

Finally, the Tibetan governor of Turkestan presented a statue made of gold and precious stones to the Arab Caliph al-Ma'mun (r. 813–833).
