The Sindhi and Urdu-speaking class in Sindh Province revolted against the One Unit policy. The violence spread to Balochistan Province, Khyber-Pakhtunkhwa and Punjab Province. The One Unit policy was a failure in West Pakistan, and its survival was seen as improbable. However, with the military coup of 1958, trouble loomed for the province when the office of Chief Minister was abolished and the President took over executive powers for West Pakistan.
