Brahui-dynasty khanate of Balochistan founded by Mir Ahmad Khan I, unifying the Kalat, Kharan, Makran, and Las Bela regions under a khan who balanced Mughal, Safavid/Persian, Durrani-Afghan, and later British overlordship while retaining internal autonomy; became a British-protected state via 1854 and 1876 treaties.
Remained a British-protected princely state through the Raj; briefly declared independence on 12 August 1947 as British paramountcy lapsed, then acceded to Pakistan on 27 March 1948 under disputed circumstances that still fuel Baloch nationalist grievance; formally dissolved as a princely state on 14 October 1955 when Pakistan's One Unit scheme merged it into West Pakistan.
