Tsänsong

Tsänsong (Brtsan-srong) was Songtsän Gampo's younger brother.

Circa 639, after Songtsän Gampo had a dispute with his younger brother Tsänsong (Brtsan-srong), the younger brother was burnt to death by his own minister Khäsreg (Mkha’s sregs) (presumably at the behest of his older brother the emperor).
