Balochistan contained a Chief Commissioner's province and four princely states under the British Raj in colonial India. The province's Shahi Jirga and the non-official members of the Quetta Municipality opted for Pakistan unanimously on 29 June 1947. Three of the princely states, Makran, Las Bela and Kharan, acceded to Pakistan in 1947 after independence. But the ruler of the fourth princely state, the Khan of Kalat, Ahmad Yar Khan, who used to call Jinnah his 'father', declared Kalat's independence as this was one of the options given to all of the 565 princely states by British Prime Minister Clement Attlee.
