Explanation:

Maharaja Hari Singh (1895 – 1961) was the last ruling Maharaja of the princely state of Jammu and Kashmir in India. He signed the Instrument of Accession on 26 October 1947, joining the whole of his princely state to the Dominion of India. He remained titular Maharaja of the state until 1952, when the monarchy was abolished and Maharaja was replaced with an elected Sadr-e-Riyasat (President of the state). Only a permanent resident of J&K could become Sadr-e-Riyasat. Once elected by the Legislative Assembly, the Sadr-e-Riyasat had to be recognised and then appointed by the President of India. In 1965, the J&K Constitution was amended (Sixth Constitution of J&K Amendment Act, 1965) by the government, which replaced the position of Sadr-e-Riyasat with the centrally nominated Governor on March 30, 1965. Karan Singh, son of Hari Singh has been the only Sadr-e-Riyasat, serving from November 17, 1952, until the post was abolished. Subsequently, he became the first Governor too.
