A state of northeast India in the eastern Himalaya Mountains between Nepal and Bhutan. Long isolated from the outside world, Sikkim was settled by Tibetans who established a kingdom there in the 1600s. A British protectorate after 1890, Sikkim passed to India in 1950 and became a state of that country in 1975.
