I. Sikkim:

At the time of Independence, Sikkim was a "Protectorate" of India. It meant that it was neither a part of India like other states nor a complete sovereign country. Sikkim's defence and foreign relation were managed by India while the power of internal administration was with the Sikkim's Chogyal Monarch. The people of the state were unhappy with this arrangement and aspired for democratic set up for governance. The majority of the people of the state were Nepali and ruler was from minority community Lepcha-Bhutia. The people of the state got support for this cause from the Government of India and from the leaders of both the communities.

In 1974's Assembly Elections, the Sikkim Congress swept the polls and they stood for greater integration with India. The Assembly sought the status of "Associate State" initially then in 1975 passed a full-fledged resolution of integration with India. This was followed by immediate referendum that sealed the approval on assembly's request of integration. The Indian Parliament accepted this plea and accepted it as a state.
