Phunstog Namgyal II, the illegitimate child of Gurmed, succeeded his father to the throne in 1733. His reign was tumultuous as he was faced with attacks by the Bhutanese and the Nepalese, apart from rebellions within Sikkim from Magars and the Tsongas in 1752. Since Namgyal II was a weak king, the Nepalese had made 17 invasions against Sikkim. Bhutan had also attacked Sikkim and occupied areas east of Tista River; however, they later withdrew to present frontiers after negotiations held at Rhenock.
