Kingdom of Sikkim

1642 CE – 1975 CE · capital Gangtok

A Buddhist Himalayan kingdom ruled by the Namgyal Chogyals for over three centuries until it became a state of India in 1975.

Origins

In 1642 three Tibetan lamas consecrated Phuntsog Namgyal as the first Chogyal at Yuksom, founding a Buddhist monarchy over the Bhutia and Lepcha peoples. Later capitals included Rabdentse and Tumlong.

Rule and society

The Chogyals ruled through Bhutia nobles and monasteries such as Pemayangtse, with Tibetan Buddhism as state religion. Sikkim lost territory to Nepal and Bhutan, and in 1861 a treaty with Britain made it a protectorate; the capital moved to Gangtok in 1894. Nepali settlers came to form a majority of the population.

Decline and legacy

After 1947 Sikkim became an Indian protectorate. Agitation against Palden Thondup Namgyal in the 1970s led to a 1975 referendum that abolished the monarchy, and Sikkim became India's 22nd state.
