when did sikkim become full fledged state of india
History of Sikkim Prime Minister Dorji appealed to the Indian Parliament for representation and change of status to statehood. On 14 April 1975, a referendum was held, in which Sikkim voted to merge with the union of India. Sikkim became the 22nd Indian State on 26 April 1975. On 16 May 1975, Sikkim officially became a state of the Indian Union and Lhendup Dorji became head of State (chief minister).
British Raj This system of governance was instituted on 28 June 1858, when, after the Indian Rebellion of 1857, the rule of the British East India Company was transferred to the Crown in the person of Queen Victoria[12] (who, in 1876, was proclaimed Empress of India). It lasted until 1947, when Britainâ€²s Indian Empire was partitioned into two sovereign dominion states: the Dominion of India (later the Republic of India) and the Dominion of Pakistan (later the Islamic Republic of Pakistan, the eastern part of which, still later, became the People's Republic of Bangladesh). At the inception of the Raj in 1858, Lower Burma was already a part of British India; Upper Burma was added in 1886, and the resulting union, Burma, was administered as an autonomous province until 1937, when it became a separate British colony, gaining its own independence in 1948.
