Tensung Namgyal, the son of Phuntsog Namgyal, founded Rabdentse as the capital of the Sikkim Kingdom. In 1670, he became the second Chogyal, or King of Sikkim. In 1642, the capital was relocated from Yuksom. Tensung Namgyal had three wives, one each from Nepal, Bhutan, and Sikkimese. The king’s offspring from each of his wives were not friendly and regularly fought over who would be the successor to the throne. As a result, several skirmishes arose between the three districts, with armies headed by the king’s progeny, resulting in significant bloodshed and property devastation over the years.
The Sikkimese force was defeated in the end, and the conflict between the Nepali and Bhutanese armies continued. The Nepali army, who won the fight, entirely destroyed Rabdentse’s palace as a result of the conflict.
