The demand for responsible government continued and the SSC launched a civil disobedience movement. The Chogyal Palden Thondup Namgyal asked India for help in quelling the movement, which was offered in the form of a small military police force and an Indian Dewan. In 1950, a treaty was agreed between India and Sikkim which gave Sikkim the status of an Indian protectorate. Sikkim came under the suzerainty of India, which controlled its external affairs, defence, diplomacy and communications. In other respects, Sikkim retained administrative autonomy.
