After Desi Sonam Rapten died in 1658, the following year the 5th Dalai Lama appointed his younger brother Depa Norbu (aka Nangso Norbu) as his successor. However, after a few months, Norbu betrayed him and led a rebellion against the Ganden Phodrang Government. With his accomplices he seized Samdruptse fort at Shigatse and tried to raise a rebel army from Tsang and Bhutan, but the Dalai Lama skilfully foiled his plans without any fighting taking place and Norbu had to flee. Four other Desis were appointed after Depa Norbu: Trinle Gyatso, Lozang Tutop, Lozang Jinpa and Sangye Gyatso.
