The First Belmang, Lobzang Dondrub, was the ninth throne holder of Labrang. A Geluk incarnation line, the line's seats were at Labrang Tashikyl and Shitsang monasteries. The line dates from the 18th century with the Second Jamyang Zhepa's recognition of the Second Belmang, Konchok Gyeltsen, as the reincarnation of Lobzang Dondrub.
