In the run-up to Partition, Pakistan and the Khan of Kalat concluded a standstill agreement intended to manage administrative continuity and relations while Kalat’s future status remained unsettled.
As British paramountcy lapsed, the Khanate of Kalat asserted independence rather than immediate accession, setting the stage for subsequent negotiations and conflict over accession to Pakistan.
At independence, the British-administered Baluchistan (centered on Quetta and surrounding areas) continued as a Chief Commissioner’s Province within Pakistan’s administrative structure, distinct from neighboring princely states.
The ruler of Las Bela acceded to Pakistan, beginning the formal incorporation of key Baloch princely states into the new dominion (with acceptance recorded shortly afterward).
The princely state of Kharan acceded to Pakistan, further reducing Kalat’s strategic options and accelerating the regional consolidation process.
Makran’s accession to Pakistan added another coastal-adjacent princely territory to Pakistan and contributed to the broader integration of Baloch princely states.
After months of disputed negotiations following its independence claim, Kalat acceded to Pakistan—an event that became central to later Baloch political contestation over the legitimacy and terms of incorporation.
Pakistan’s Governor-General formally accepted Kalat’s accession, completing the legal step that made the accession operative within Pakistan’s constitutional framework at the time.
Prince Agha Abdul Karim (from the Kalat ruling family) led an armed revolt against the accession, marking an early insurgent challenge tied to the contested integration of Kalat.
Kalat, Kharan, Las Bela, and Makran were merged into the Baluchistan States Union (BSU) with its capital at Kalat, creating a single administrative unit for several former princely states while maintaining a distinct identity from the Chief Commissioner’s Province.
Pakistan announced the One Unit plan to merge western provinces and state territories into a single province (West Pakistan), a major structural shift that would end the separate administrative existence of both the BSU and the Chief Commissioner’s Province.
Pakistan’s Constituent Assembly passed the Establishment of West Pakistan Act, 1955, providing the legal basis for integrating multiple western provinces and states into the new province of West Pakistan.
The Establishment of West Pakistan Act received the Governor-General’s assent and was published, moving One Unit from legislative passage toward full administrative implementation.
On the appointed day for One Unit, the Baluchistan States Union and the Baluchistan Chief Commissioner’s Province were dissolved as separate entities and incorporated into the new province of West Pakistan, completing this phase of administrative integration (1947–1955).
