Resistance here does not look like the national story and it would be dishonest to make it. Sikkim was never part of British India: it was a protected kingdom, so there was no colonial administration to agitate against and no Congress organisation inside it, and its political life before 1947 was a matter between the Chogyal, the monastic establishment and a British Political Officer. Darjeeling and Kalimpong were British territory, but a plantation district rather than an ordinary one - most of its population had arrived within living memory to work in tea, and organised politics there formed around the hill population's demand for representation, through the Hillmen's Association from 1907 and the All India Gorkha League from 1943, more than around Congress. The one action here that belongs squarely to the national movement was carried out by revolutionaries who came up from Bengal for the purpose: the attempt on the Governor at Lebong in 1934. The honest summary is that this ridge produced a great deal of politics and very little anti-colonial insurgency.
The Sikkim court's resistance to British expansion1849–1861
Sikkim's court, with a minister of pro-Tibetan sympathies at its head, tried to hold the line against British encroachment from Darjeeling and in 1849 detained Archibald Campbell and the botanist Joseph Hooker when they crossed into Sikkim.
Outcome: The detention was used as grounds for annexing roughly 1,700 square kilometres between the Mechi and the Teesta in 1850, and the Treaty of Tumlong of 1861 ended the kingdom's control of its own external relations. The attempt to resist accelerated exactly what it was meant to prevent.
The Lebong racecourse action6 May 1934
Members of a Bengal revolutionary network made an attempt on the life of John Anderson, Governor of Bengal, at the racecourse at Lebong above Darjeeling. A revolver was carried up concealed in a harmonium; the shot wounded the Governor slightly.
Outcome: Those involved were arrested within a fortnight and tried by a special tribunal. Ujjwala Majumdar was sentenced to fourteen years and released from Dhaka jail in April 1939.
The hill associations and the demand for representation1907–1943
Political organisation among the Darjeeling hill population took the form of associations petitioning for separate representation rather than of civil disobedience. The Hillmen's Association submitted a memorandum to the Minto-Morley reforms in 1909; the All India Gorkha League was founded in 1943.
Outcome: Damber Singh Gurung, who founded the League, was elected to the Constituent Assembly for Bengal in November 1946 and served until his death in 1948.
