Tenzing Namgyal, the next king was also a weak ruler, and his sovereignty saw most of Sikkim being appropriated by Nepal. The Chogyal was forced to flee from Rabdentse to Lhasa where he died in 1780. Tshudpud Namgyal, his son returned to Sikkim in 1793 to reclaim the throne with the help of China. Finding Rabdentse too close to the Nepalese border, he shifted the capital to Tumlong. Consequent to the repeated attacks by the Bhutanese and Nepalese over the many invasions, the capital city was reduced to ruins by the liberating army of Nepal.
