<P> During the period of the British Raj , there were four princely states in Balochistan : Makran , Kharan , Las Bela and Kalat . The first three acceded to Pakistan . However , the ruler of the fourth princely state , the Khan of Kalat Ahmad Yar Khan , declared Kalat 's independence as this was one of the options given to all princely states . The state remained independent until it was acceded on 27 March 1948 . The signing of the Instrument of Accession by Ahmad Yar Khan , led his brother , Prince Abdul Karim , to revolt against his brother 's decision in July 1948 , causing an ongoing and still unresolved insurgency . </P>
