Khan of Kalat or Khan-e-Qalat (Balochi: خان قلات) is the title of the former rulers of the Khanate of Kalat. Kalat state is now a part of Balochistan Province, Pakistan. The rulers in Kalat first were subjected to Mughal emperor Akbar in Delhi after 1839 to the British, and since 1948 to the Pakistani government.
The rulers of Kalat held the title of Vali originally but in 1739 they also took the title (Begler Begi) Khan, usually shortened to just Khan. The last Khan of Kalat was also the President of the Council of Rulers for the Baluchistan States Union.
The Khans of Kalat belonged to a Baloch hill chieftain named Qambar (or Qumbar). His tribe was hired by Sehwa, the Raja of Kalat, a Hindu princely state, to protect against marauding tribes from the Multan, Shikarpur and Upper Sind areas.Mir Qambar Baloch and his troops successfully repressed the incursion, but afterward, they deposed the raja and Mir Qambar Baloch became the first Vali.
