On this day May 16, 1975
Based on the results of a referendum held about one month earlier, Sikkim abolished its monarchy and was annexed by India, becoming its 22nd state.
In 1973, riots in front of the palace led to a formal request for protection from India. The Chogyal was proving to be extremely unpopular with the people.
In 1975, theKazi (Prime Minister) appealed to the Indian Parliament for a change in Sikkim’s status so that it could become a state of India. In April, the Indian Army took over the city of Gangtok and disarmed the Palace Guards.
A referendum was held in which 97.5% of the voting people (59% of the people entitled to vote) voted to join the Indian Union. A few weeks later, on May 16, 1975, Sikkim officially became the 22nd state of the Indian Union and the monarchy was abolished.
