Songtsen Gampo
Some accounts say that when Gungsong Gungtsen reached the age of thirteen (twelve by Western reckoning), his father, Songtsen Gampo, retired, and he ruled for five years (which could have been the period when Songtsen Gampo was working on the new constitution). Gungsong Gungtsen is also said to have married 'A-zha Mang-mo-rje when he was thirteen, and they had a son, Mangsong Mangtsen (r. 650-676 CE). Gungsong Gungtsen is said to have only ruled for five years when he died at eighteen. His father, Songtsen Gampo, took the throne again. Gungsong Gungtsen is said to have been buried at Donkhorda, the site of the royal tombs, to the left of the tomb of his grandfather Namri Songtsen (gNam-ri Srong-btsan). The dates for these events are very unclear.
According to Tibetan tradition, Songtsen Gampo was enthroned while still a minor as the thirty-third king of the Yarlung Dynasty after his father was poisoned circa 618. He is said to have been born in an unspecified Ox year and was 13 years old (12 by Western reckoning) when he took the throne. This accords with the tradition that the Yarlung kings took the throne when they were 13, and supposedly old enough to ride a horse and rule the kingdom. If these traditions are correct, he was probably born in the Ox year 605 CE. The "Old Book of Tang" notes that he "was still a minor when he succeeded to the throne."
